Co-Trustees at Commencement

1. Cotrusteeship is a single fiduciary office jointly held; the trustees function as a plural body but owe a unitary duty to the beneficiaries. Restatement (Third) of Trusts § 39; UTC § 703.
2. Each nominated cotrustee must independently accept the office under UTC § 701; acceptance by one does not bind the others.
3. Under UTC § 703(a), cotrustees who cannot reach unanimity may act by majority; the older common-law rule of unanimity survives in some non-UTC jurisdictions.
4. Each cotrustee has an affirmative duty to participate in the administration of the trust. UTC § 703(d); Restatement (Third) § 81.
5. A dissenting cotrustee is generally not liable for a majority action to which she has properly dissented and, when required, communicated the dissent. UTC § 703(h).
6. Every cotrustee has an affirmative duty to prevent, and to redress, a breach of trust by a cotrustee. UTC § 703(g); Restatement (Third) § 81 comment b.
7. Delegation among cotrustees is permissible where prudent and where the delegating trustee retains supervisory responsibility. UTC § 703(e); Restatement (Third) § 80.
8. Vacancy in a cotrustee office at commencement does not suspend administration; the remaining trustees may act, subject to the trust's terms and any statutory minimums. UTC § 704.

Upon completing this chapter, the reader should be able to:

1. Explain the doctrinal and practical reasons for appointing multiple trustees.
2. Apply UTC § 701 to the acceptance of office by each of several nominated cotrustees.
3. Distinguish the common-law unanimity rule from the UTC majority-action rule, and identify the governing rule in a given jurisdiction.
4. Apply UTC § 703 to decision-making, delegation, participation, dissent, and liability among cotrustees.
5. Identify the affirmative duty of each cotrustee to prevent and to redress a cotrustee's breach, and the mechanics of a proper dissent.
6. Analyze the effect of a cotrustee's resignation or removal during the commencement of administration.
7. Design a decision-making, meeting, and recordkeeping protocol for a cotrusteeship.
8. Recognize the recurrent administrative errors that arise in cotrusteeships and construct protocols to avoid them.

The office of trustee is often shared. Settlors appoint multiple trustees for reasons that are practical, structural, and doctrinal: to combine complementary skills (a corporate trustee for custody and investment, an individual trustee for family knowledge and judgment); to distribute administrative burden and reduce the risk of single-point failure; to introduce internal checks upon discretion; to preserve continuity across generations; and, in specialized trusts, to allocate functions among specialists. See Restatement (Third) of Trusts § 34 comment a; Bogert §§ 554–555.

The choice of multiple trustees is not merely additive. It creates a distinct governance structure — the cotrusteeship — with its own rules of decision, participation, delegation, and liability. Volume II Chapters 1–3 have treated the trustee as a single office; this chapter addresses the doctrinal and practical consequences of dividing that office among several persons.

The dominant doctrinal proposition is that the office of trustee is single even when the persons who hold it are many. Restatement (Third) of Trusts § 39; Bogert § 555. The cotrustees are not separate fiduciaries owing separate duties; they are joint holders of one office, and each owes the full fiduciary duty to the beneficiaries. The plural body acts; but the office is one and the duty is one.

The unitary character of the office has three consequences that recur throughout the chapter. First, the trust property is held by the cotrustees jointly, not in undivided shares; on the death or resignation of one, title vests in the remaining trustees without conveyance. UTC § 704 comment. Second, decisions of the cotrusteeship — however reached internally — are decisions of the trustee for external purposes. Third, breach by one cotrustee is, in defined circumstances, breach by the others; participation, acquiescence, or failure to act may all be sources of liability. See § 4.16, infra.

The number of trustees is generally set by the trust instrument. Where the instrument provides for a specific number, that number governs, and the mechanism by which vacancies are filled is generally specified. Where the instrument is silent, the default rule permits any number consistent with the settlor's intent, subject to the courts' equitable jurisdiction to appoint or remove trustees where necessary to preserve the trust. UTC § 704(c)–(d); Restatement (Third) § 34 comment b.

Instrument-specific structures common in modern practice include: two individual cotrustees with unanimity required; three cotrustees with majority action; a corporate trustee paired with one or more individual cotrustees; a directed-trust structure in which some cotrustees are subject to the direction of a trust director under the Uniform Directed Trust Act; and trust-protector arrangements alongside the cotrusteeship. Each structure has doctrinal and practical implications treated in later Parts.

As Chapter 1 established, the office of trustee begins with acceptance. UTC § 701; Restatement (Third) § 35. The rule applies severally to each nominated cotrustee: acceptance by one does not accept for the others, and a nominated cotrustee who does not accept has never held the office. Restatement (Third) § 35 comment c.

Acceptance by cotrustees is best documented individually. Each nominated cotrustee should execute a separate written acceptance or a joint acceptance instrument identifying each accepting person. The written acceptance forecloses later doubt as to when — and by whom — the office was assumed.

Non-simultaneous acceptance is common. A corporate trustee may accept promptly upon presentation of the instrument, while an individual cotrustee requires time to consult counsel. During the interval the accepting trustee is fully in office. She holds the trust property alone (or jointly with any other accepting trustee) and owes the full fiduciary duty. Her authority to act extends to whatever the trust and applicable law permit a sole trustee to do; the future acceptance of another nominated cotrustee neither retroactively validates nor invalidates her acts. Restatement (Third) § 39 comment d.

The accepting trustee should nonetheless act with awareness of the pending acceptance. Non-emergency decisions that will bind the cotrusteeship over the long term — investment allocations, custody arrangements, discretionary distributions — are ordinarily best deferred until the full trustee body is in place. Emergency and protective measures under UTC § 809 should not be deferred.

A nominated cotrustee may decline the office by any conduct manifesting rejection, including inaction beyond a reasonable period. UTC § 701(a)–(b). Declination by one nominated cotrustee does not, without more, defeat the trust or the cotrusteeship: the accepting trustees continue in office, and the trust instrument's successor provisions (or, if none, UTC § 704) supply any needed successor. See § 4.24, infra.

The declining nominee should communicate declination in writing to the settlor (if living), to the other trustees, and to the qualified beneficiaries who would otherwise expect her acceptance. Documentation of declination is important because the fiduciary consequences of accepting the office are substantial; a subsequent claim that the nominee "agreed to serve" absent formal acceptance is not uncommon.

Qualification, as distinct from acceptance, refers to any additional steps required before a trustee is permitted to act. For most inter vivos trusts governed by the UTC, qualification is subsumed in acceptance: no bond is required (UTC § 702(a)), and no court confirmation is required for accepted trustees. For testamentary trusts, some jurisdictions require issuance of letters of trusteeship by the probate court; the cotrustees together must present the will admitted to probate and satisfy any statutory requirements. See N.Y. Surrogate's Ct. Proc. Act § 1408; Cal. Prob. Code § 17200.

Corporate cotrustees must additionally satisfy any regulatory prerequisites — trust department authorization, out-of-state qualification where required, and the internal committee approvals customary in institutional practice. The remaining cotrustees should verify that qualification has been completed before joint action is taken in reliance upon it.

Joint fiduciary responsibility attaches upon acceptance by more than one trustee. From that moment forward the trustees hold the office together and owe the duties of that office together. Restatement (Third) § 39 comments a, d. Each cotrustee is fully answerable to the beneficiaries for the administration of the trust from her acceptance forward, subject to the allocation rules of §§ 4.16–4.20, infra.

The consequence at inception is that the marshaling duties of Chapter 3 — identification, collection, protection, segregation, earmarking, titling, and inventory — are joint duties. Each cotrustee has a personal responsibility to see that they are discharged; none may passively rely on another. UTC § 703(d); Restatement (Third) § 81 comment b.

At common law, cotrustees could act only unanimously. Restatement (Second) of Trusts § 194; Bogert § 555. The rule reflected the view that the trust was a matter of confidence in named persons and that the settlor who named several intended each to consent to every act. In the absence of a controlling statute or trust provision, some non-UTC jurisdictions continue to apply a unanimity default.

The unanimity rule is inconvenient in practice. It gives every cotrustee an effective veto and, where cotrustees disagree, forces recourse to the courts to break the impasse. Its limitations became evident as institutional trust practice matured and as the number of cotrustees in family wealth structures expanded. The Uniform Trust Code responded by reversing the default.

UTC § 703(a) provides: "Cotrustees who are unable to reach a unanimous decision may act by majority decision." The rule reverses the common-law default. Where the trust instrument is silent and a UTC (or UTC-derived) statute governs, cotrustees may act by majority. Comment to UTC § 703. Most states adopting the UTC have retained the majority default.

The rule is a default only. A trust instrument requiring unanimity, supermajority, or specific-trustee consent controls. Where the trust instrument provides that certain decisions require the concurrence of a particular cotrustee (for example, an investment cotrustee for all investment matters), that provision is enforceable as an allocation of function; it does not create the vice of unanimity but rather a functional allocation treated at § 4.13, infra.

An even-numbered cotrusteeship acting by majority default is vulnerable to deadlock. Two-trustee arrangements in particular have no majority: two-for-nothing is unanimity; one-and-one is impasse. The trust instrument may address the problem by (a) requiring unanimity, thereby accepting the veto but making it explicit; (b) appointing an odd number of trustees; (c) providing a tie-breaker (a designated trustee, a trust protector, or a specified process); or (d) referring the deadlock to a designated committee or to arbitration.

Where the trust instrument does not resolve the deadlock, the trustees may petition the court for instruction or removal. UTC §§ 201, 706. Persistent deadlock impairing administration is itself a ground for removal under UTC § 706(b)(3) ("lack of cooperation among cotrustees substantially impairs the administration of the trust"). See Bogert § 559.

UTC § 703(b) provides that, where a cotrustee is unavailable to participate because of absence, illness, disqualification under other law, or other temporary incapacity, the remaining cotrustees may act for the trust to the extent required by the circumstances. The provision recognizes that emergency and time-sensitive administrative duties — the protection of trust property under UTC § 809, the payment of a tax or debt, the execution of an insurance renewal — cannot await the return of an absent cotrustee.

The permission is limited: it authorizes action only "to the extent required by the circumstances." The remaining trustees must promptly inform the absent cotrustee and, upon her return, integrate her into the ordinary decisional process. Ratification, or lack of it, then applies to the interim actions on their own merits.

Modern trust instruments increasingly allocate functions among cotrustees. A common structure names one cotrustee for investment decisions (frequently a corporate trustee), one for distribution decisions (frequently an individual cotrustee close to the family), and specifies that decisions within an allocated function require only the responsible cotrustee's concurrence. The Uniform Directed Trust Act formalizes a related pattern in which a trust director (not a cotrustee) directs certain functions.

Functional allocation is enforceable and, subject to the trust instrument, materially alters the liability landscape. See UTC § 703(h); UDTA §§ 8, 9. A cotrustee who is not responsible for a function ordinarily is not liable for the responsible cotrustee's actions within that function, provided the non-responsible trustee has neither acquiesced in a known breach nor failed to perform the duties allocated to her. The interaction between functional allocation and the duty to prevent breach is treated at § 4.19, infra.

UTC § 703(e) provides that a cotrustee may delegate to a cotrustee the performance of a function "that the trustee reasonably could not be required to perform personally." The provision codifies the modern prudent-delegation principle applied within the cotrustee body. It complements UTC § 807, which permits delegation to agents outside the cotrustee body under the prudent-investor standard.

The delegating cotrustee retains supervisory responsibility. She must (a) exercise reasonable care in selecting the delegate cotrustee for the function, (b) establish the scope and terms of the delegation consistently with the trust's purposes, and (c) periodically review the delegate's performance. Restatement (Third) § 80(a); UTC § 703 comment. Delegation does not relieve the delegating trustee of the underlying fiduciary duty; it distributes the mechanism by which the duty is discharged.

Delegation among cotrustees should be documented at inception in a written protocol addressing: (a) the functions subject to delegation; (b) the delegate cotrustee for each function; (c) the frequency and manner of reporting to the non-delegating cotrustees; (d) the criteria and process for revocation of the delegation; and (e) the treatment of conflicts and coordination questions. The protocol should be part of the permanent administrative record described at § 3.23.

Third parties dealing with the cotrusteeship — banks, brokers, custodians, counterparties — are entitled to rely on the trust instrument as evidence of authority. Where the trust instrument allocates a function to a specific cotrustee, third parties may generally rely on that cotrustee's signature within the allocated function. Where the cotrustees have adopted an internal delegation protocol not memorialized in the trust instrument, they may need to provide third parties a Certification of Trust under UTC § 1013 that reflects the delegation.

UTC § 703(d) provides: "If a cotrustee is unavailable to perform duties because of absence, illness, disqualification under other law, or other temporary incapacity, and prompt action is necessary to achieve the purposes of the trust or to avoid injury to the trust property, the remaining cotrustees may act for the trust." More broadly, Restatement (Third) § 81 establishes an affirmative duty on each cotrustee to participate in the performance of the trust.

Participation is not optional. A cotrustee who fails to participate — who does not review reports, attend meetings, engage with proposed decisions, or discharge her share of the administrative work — breaches the duty owed to the beneficiaries independently of the substantive merit of any decision she failed to influence. Restatement (Third) § 81 comment a; Bogert § 556. Absentee cotrusteeship is itself a breach.

UTC § 703(h) provides: "A trustee who does not join in an action of another trustee is not liable for the action." The provision protects the dissenting trustee from vicarious liability for a decision she opposed. Its protection is not automatic: the dissent must be effective in fact and, in practice, documented in the record.

A properly documented dissent has three elements:

1. The dissenting cotrustee expresses her disagreement at the time the decision is made — before the action is taken, not after.
2. The dissent is communicated to the other cotrustees, and the substance of the dissent is recorded.
3. The dissenting cotrustee takes such further action as the duty to prevent breach may require. § 4.19, infra.

The prudent practice is to record a dissent contemporaneously in the minutes of the cotrustee meeting (or in a written record where there is no formal meeting), and to preserve the record as part of the permanent administrative file. See § 4.26, infra.

Restatement (Third) § 81 imposes a duty of cooperation among cotrustees. The duty complements, and does not conflict with, the right to dissent: the cotrustee who dissents from a decision remains obligated to cooperate in the administration of the trust generally and, in particular, to facilitate the orderly implementation of decisions properly reached notwithstanding her dissent. The line runs between dissent (permitted, sometimes required) and obstruction (breach). Bogert § 557.

Where cooperation has broken down to a degree that materially impairs administration, UTC § 706(b)(3) permits removal. The remedy is severe and generally reserved for cases in which the trust cannot be administered under the existing composition of the cotrusteeship. The prudent course, where possible, is mediated resolution short of removal.

UTC § 703(g) provides: "Each trustee shall exercise reasonable care to prevent a cotrustee from committing a serious breach of trust, and to compel a cotrustee to redress a serious breach of trust." The duty is affirmative. Restatement (Third) § 81 comment b. A cotrustee who observes, or should observe, that a cotrustee is committing or about to commit a serious breach owes an obligation to intervene.

The duty operates through a graduated set of responses:

1. Inquiry — request information and clarification of the questioned action.
2. Objection — communicate disagreement and, where appropriate, refuse concurrence.
3. Formal dissent — document opposition contemporaneously.
4. Corrective demand — request or require that the cotrustee redress the breach or refrain from the threatened action.
5. Judicial recourse — petition the court under UTC §§ 201, 706, or 1001 for instruction, removal, or remedial relief.
6. Notice to beneficiaries — where required to satisfy the duty to inform under UTC § 813, communicate the material facts to the qualified beneficiaries.

Not every response is required in every case; the duty is one of reasonable care under the circumstances. But mere disagreement, unaccompanied by any of these steps, is generally insufficient to discharge the duty. Bogert § 561.

UTC § 703(g) also imposes the duty to "compel a cotrustee to redress a serious breach of trust" that has occurred. The non-breaching cotrustees must take reasonable steps to secure restoration of the trust to the position it would have occupied but for the breach: recovery of property wrongfully transferred, imposition of a surcharge, and, where the breach is ongoing, its immediate cessation. UTC § 1002 (damages); § 1003 (recovery from trustee).

The obligation runs to the beneficiaries. A non-breaching cotrustee who fails to compel redress may become independently liable for the loss occasioned by her failure. See § 4.22, infra. The corollary is that the non-breaching cotrustees should not accept representations of "cure" without substance; the duty is to compel actual redress, not to accept declaratory assurances.

The default liability rule is joint. Restatement (Third) § 39 comment d; Restatement (Second) § 224. Because the cotrustees hold a single office, a breach in the administration of that office is a breach by the trustee body, and each cotrustee is answerable to the beneficiaries for the loss.

Two categories of allocation modify the default. First, functional allocation by the trust instrument, or by a properly documented internal delegation under UTC § 703(e), may confine primary responsibility for a function to a designated cotrustee. Second, dissent under UTC § 703(h) may relieve a non-participating cotrustee of liability for a decision to which she has properly dissented. Both modifications are subject to the overriding duty to prevent or redress breach under § 703(g).

The doctrinally distinct — and most consequential — form of cotrustee liability is liability for failure to act. UTC § 703(g); Restatement (Third) § 81 comment b; Bogert § 561. A cotrustee who observes a breach and does nothing, who fails to participate in decisions and thereby permits a breach to go undetected, or who accepts a facially inadequate cure is liable for the resulting loss to the extent her omission caused it.

The rule is not one of strict liability. The standard is reasonable care under the circumstances. But the case law and the Restatement are clear that passive cotrusteeship is a source of liability at least as important as active misconduct. See Bogert § 561; Scott & Ascher § 24.3. Beneficiaries who cannot identify who committed the affirmative breach can often identify who failed to prevent or redress it, and the failure supports independent recovery.

UTC § 1009 permits a beneficiary to consent to, release, or ratify a trustee's conduct. Where obtained after full disclosure and from a beneficiary not under a disability, a consent, release, or ratification may bar recovery against the trustees, including the non-participating cotrustee. The doctrine applies to cotrustee liability in the same manner as to sole-trustee liability, subject to the ordinary limits on the effectiveness of such instruments. See § 1009 comment.

Reliance on prospective releases at inception is disfavored. A release procured before the events to which it purports to apply is generally ineffective; the beneficiary cannot release a wrong not yet done and cannot make an informed judgment about what has not yet occurred. Restatement (Third) § 96 comment g.

A cotrustee may resign under UTC § 705 by giving notice to the qualified beneficiaries, the settlor if living, and the other cotrustees, or by court order for cause. Resignation at inception — for example, upon the resigning trustee's post-acceptance recognition of a conflict, or upon a health event — does not terminate the cotrusteeship if others remain. The remaining trustees continue in office; the trust instrument's successor provisions fill any vacancy, and, absent instrument provisions, UTC § 704 supplies the default appointment mechanism.

The resigning cotrustee is not thereby relieved of accountability for the period during which she served. She remains subject to accounting and, in appropriate cases, to surcharge for breaches occurring during her tenure. UTC § 705(c); Restatement (Third) § 36. The resignation instrument should identify the effective date and preserve the resigning trustee's ability to complete any transition responsibilities. See § 4.27, infra.

UTC § 706 permits removal of a trustee by the court for cause, including serious breach, lack of cooperation among cotrustees, unfitness, or unwillingness to administer the trust effectively. Removal at commencement is uncommon but not unprecedented; a nominated cotrustee's undisclosed conflict, or a demonstrated inability to serve, may be raised early.

The effect of vacancy — whether by declination, resignation, removal, or death — is governed by UTC § 704: any specified successor takes office; failing that, a person selected by a majority of the qualified beneficiaries under § 704(c) may be appointed; failing that, the court may appoint a successor. Administration continues by the remaining trustees during the interim, and the trust property vests in them without conveyance. UTC § 704(a) comment.

A cotrusteeship functions only as well as its governance. At inception, the cotrustees should adopt a governance protocol addressing:

• Decision-making rule: the applicable standard (unanimity, majority, functional allocation) and the mechanism for tie-breaking or deadlock resolution.
• Meetings: regular schedule, permitted forms (in-person, telephonic, written consent), and quorum.
• Notice: the manner and lead-time for calling meetings and circulating agenda items.
• Records: minutes, dissent documentation, and retention consistent with UTC § 810 and Restatement (Third) § 83.
• Delegation and functional allocation: responsibilities of each cotrustee within the office and the terms of any internal delegation under UTC § 703(e).
• Third-party dealings: signatory authority, Certifications of Trust under UTC § 1013, and coordination with counsel and custodians.
• Conflicts: disclosure protocol, recusal, and the treatment of conflicts under UTC § 802.
• Beneficiary communications: who speaks for the cotrusteeship in communications required by UTC § 813, and how disagreements about communications are resolved.

The protocol should be part of the permanent administrative record and should be reviewed periodically. Where the trust instrument contains a governance framework, the protocol is subordinate to it; where the instrument is silent, the protocol supplies the operational infrastructure that the office requires.

Certain errors recur in cotrusteeships and generate a disproportionate share of early liability:

1. Undocumented acceptance. Nominated cotrustees begin acting without written acceptance instruments, producing later disputes over when the office began.
2. Assumed unanimity or assumed majority. Cotrustees act without confirming the governing decision rule under the trust instrument and applicable statute.
3. Passive cotrusteeship. One cotrustee (often an individual paired with a corporate trustee) treats her role as ceremonial and does not participate in decisions, meetings, or record review — exposing her to liability under § 703(d) and § 703(g).
4. Unrecorded dissent. A cotrustee opposes an action orally but does not document the dissent, forfeiting the protection of § 703(h).
5. Delegation without documentation. Functions are informally allocated among cotrustees without written protocol, complicating later analysis of responsibility.
6. Failure to intervene. A cotrustee observes questionable conduct by a cotrustee and neither inquires, objects, nor takes further action, incurring independent liability under § 703(g).
7. Two-trustee deadlock. A two-cotrustee arrangement with unanimity encounters an impasse without any pre-agreed resolution mechanism, forcing recourse to the courts.
8. Third-party confusion. Institutions receive inconsistent instructions from cotrustees because no Certification of Trust or signatory protocol has been provided.

Each error is preventable by the routine application of the governance and documentation protocols described in this chapter. None is exotic; all are recurrent.

The following framework identifies the minimum institutional standard for the opening stages of a cotrusteeship. It is not a substitute for professional judgment or for jurisdictional variation.

Days 1–15. Written acceptance by each nominated cotrustee. Confirmation of the decision-making rule under the trust instrument and applicable statute. Circulation of the trust instrument, any amendments, and a summary of pending matters to each cotrustee. Preliminary identification of any conflicts under UTC § 802.

Days 16–30. Adoption of a written governance protocol addressing decision-making, meetings, records, delegation, and third-party dealings. Preparation of a Certification of Trust under UTC § 1013. Coordination with counsel, custodians, and beneficiaries as required. Delivery of UTC § 813(b) notices as described in Chapter 2.

Days 31–60. Integration of the marshaling protocol of Chapter 3 into the cotrusteeship's operations. Allocation of custody, investment, and distribution responsibilities consistently with the trust instrument. Confirmation of insurance, titling, and fiduciary-account arrangements. First recorded cotrustee meeting, with minutes preserved in the administrative file.

Days 61–90. Completion of the initial inventory as a cotrustee body. Review and documentation of any interim decisions taken during the acceptance interval. First reporting cycle initiated. Review of the governance protocol against experience of the first quarter.

By the close of the ninety-day window, the cotrusteeship should be operating as a coordinated fiduciary body, with a documented governance framework, defined lines of responsibility, and a permanent administrative record adequate to support the accountability that each cotrustee owes to the beneficiaries.

Cotrusteeship is a single office held jointly. Its distinctive doctrinal features — acceptance by each nominee, majority decision under the UTC default, permitted delegation, required participation, protected dissent, and the affirmative duty to prevent and redress breach — organize the practical realities of shared trusteeship into a framework the beneficiaries can rely upon. The framework requires discipline. Cotrustees who accept the office jointly must administer it jointly, or the office will fail even as its holders remain in place.

This chapter completes Part I of Volume II. Chapters 1–4 have set the doctrinal and administrative foundations of the trustee's inception duties: acceptance and qualification, notice and information, marshaling of the trust estate, and cotrusteeship. Part II turns from inception to the substantive fiduciary duties that structure ongoing administration.
