Successor Trustee
Updated June 7, 2026
When the successor trustee's role begins
A successor trustee has no authority while the original trustee is alive and capable. Their role begins when the trust document's succession conditions are met — usually the incapacity or death of the prior trustee. A trust document typically specifies how incapacity is established (often by certification from one or two physicians).
Choosing a successor trustee
The successor trustee should be someone who is organized, honest, and capable of managing financial matters or willing to engage professionals to help. Unlike an executor, the successor trustee may need to administer the trust for years — making investment decisions and handling distributions over time. Some people name an adult child; others name a corporate trustee (a bank or trust company) for continuity and impartiality.
Making the handoff smooth
Your successor trustee needs to find the trust document, all asset titling records, and a clear picture of what the trust holds. Keeping those in one organized, accessible place — and making sure your successor trustee knows where to look — makes the transition far less difficult.
Related terms
- Trustee — A trustee is the person or institution responsible for managing the assets held inside a trust, in accordance with the trust document and in the interest of the beneficiaries. The trustee holds legal title to the trust property but must use it only for the purposes the trust specifies.
- Living Trust — A living trust is a legal arrangement created during a person's lifetime in which they transfer ownership of their assets to the trust — typically naming themselves as the initial trustee — to be managed for their benefit while alive and distributed to named beneficiaries when they die, all without going through probate. Because the trust, not the individual, holds the assets, those assets pass directly to beneficiaries outside of the probate process.
- Testamentary Trust — A testamentary trust is a trust created by the instructions in a will, which comes into existence only after the testator dies and the will has been admitted to probate. Unlike a living trust, it does not exist during the testator's lifetime and does not avoid probate — the assets must pass through probate before they can be transferred into the trust.
- Executor — An executor is the person named in a will to carry out its instructions — gathering the deceased's assets, paying debts and taxes, and distributing what remains to the beneficiaries. The executor is accountable to the probate court and must act in the interest of the estate, not their own.
- Power of Attorney — A power of attorney is a legal document in which one person (the principal) grants another person (the agent or attorney-in-fact) the authority to act on their behalf in financial and legal matters. A standard power of attorney typically becomes invalid if the principal loses mental capacity — unlike a durable power of attorney, which survives incapacity.
