How to Choose a Successor Trustee

Naming a successor trustee is the one decision in a living trust that is about a person rather than property, and the one people most often want to get right and least often understand. This guide explains what the law expects of the role, using the Texas and Florida trust codes as examples, and then works through the practical choices.

What the law expects of a trustee

State trust codes describe the job in a sentence and then in detail. Texas: the trustee shall administer the trust in good faith according to its terms and the Trust Code (Property Code section 113.051). Florida: upon acceptance of a trusteeship, the trustee shall administer the trust in good faith, in accordance with its terms and purposes and the interests of the beneficiaries (section 736.0801). The trust document is the trustee's instruction manual; the statutes fill the gaps.

Communication is a legal duty, not a courtesy. Florida's trustee must keep the qualified beneficiaries reasonably informed, give notice within 60 days of accepting the trust and within 60 days of a revocable trust becoming irrevocable (which is what happens at the settlor's death), provide a copy of the trust instrument on request, and account to the beneficiaries at least annually for an irrevocable trust (section 736.0813). In Texas, a beneficiary may demand an accounting in writing (section 113.151). A successor trustee who cannot keep records or answer questions will struggle with these duties no matter how well meaning.

The qualities that matter

• Trustworthiness. The trustee holds legal title to everything in the trust, and no one checks the trustee's work day to day.
• Organization. Inventories, valuations, notices, accountings, tax filings and receipts. The role is closer to bookkeeping than to leadership.
• Availability. Settling a trust after a death takes months of attention. A successor who lives far away, travels constantly, or is in the middle of their own crisis can serve, but the work will be harder.
• Temperament. The trustee is the person who tells a sibling the answer is no because the trust says so. Someone who avoids conflict, or who enjoys it, is a poor fit.
• Willingness. Ask. A person who learns of the appointment after your death may decline, and both Texas (section 112.009) and Florida (section 736.0704) treat a declined trusteeship as a vacancy to be filled.

Child, spouse, friend or professional

Many families name a spouse first and an adult child or children next, and the law allows it: a person named as trustee who is also a beneficiary is not disqualified from acting (Texas section 112.008), and the only structural limit is that the same person may not be the sole trustee and the sole beneficiary, which would collapse the trust (Florida section 736.0402; Texas section 112.034). The question is not whether a child can serve but whether the child you are considering has the qualities above and whether naming one child over another will damage the family. Some parents name two children as cotrustees to share the work and the decisions; that helps when the two work well together and hurts when they do not, because both must act. A trusted friend with a financial or administrative background can be a good choice when the children are young, far away, or at odds. A bank trust department or a licensed professional fiduciary charges a fee set by its schedule and brings experience and neutrality; families with substantial assets, a business, or beneficiaries who do not get along often find the fee worth paying.

Always name an alternate

People die, decline, move away and fall ill. The statutes handle a vacancy, but only in the order they set. In Florida, a vacancy in a trusteeship that must be filled is filled first by the person named or designated in the trust as successor, then by a person appointed by unanimous agreement of the qualified beneficiaries, and only then by the court (section 736.0704). In Texas, if the person named does not accept, is dead or lacks capacity, the alternate named in the trust may accept; if no alternate is named, the court appoints a trustee on the petition of an interested person (section 112.009). Naming a first successor and at least one alternate keeps the choice yours and keeps it out of court.

Incapacity as well as death

The successor trustee's job can begin while you are alive. A living trust typically provides that the successor takes over if the settlor becomes unable to manage the trust, and says how incapacity is determined. That is a different role from the agent under a durable power of attorney, who handles property outside the trust, and from the health care agent; many people name the same person to all three so that one trusted individual can act, and others deliberately separate them. Whichever you choose, the people you name should know about each other.

Before you sign

Tell your chosen successor where the trust document is, who the attorney or service was, and what property is in the trust. A successor trustee who has to search for the trust and reconstruct the assets loses months. The Complete Estate Plan comes with a guide titled Your Next Steps, written for you, the person who created the trust. It lists the documents you received, walks through signing them and funding the trust, names each person you appointed, including your successor trustee and any alternate, reminds you to tell each of them what the role is and where your documents are kept, and covers where to keep the originals and who should have copies.
