A trust does not end because a trustee dies. The trust assets pass to the successor trustee named in the trust agreement, who carries on the administration. If the agreement names no successor, or none of the named successors can serve, a beneficiary or any other interested person may petition the court to appoint one.
A trust is an agreement by which the grantor transfers assets to a trustee, who manages and administers them for the benefit of designated beneficiaries. In a living trust the grantor is usually also the trustee and the beneficiary. When that grantor-trustee-beneficiary dies, the trust assets pass to the successor trustee named in the agreement, who manages them for the successor beneficiaries. Trusts are a popular planning tool because they avoid probate, can minimize taxes, and allow wealth to be managed and distributed for a long time after death.
A trustee is the person the grantor appoints to hold, own and manage the trust property. The trust document usually names a trustee and several successors, in case a trustee dies, becomes incapacitated, resigns, is disqualified or otherwise cannot serve. Sometimes the document does not name enough successors, especially when the trust is meant to last for several generations, and at some point there is no successor left. The trust does not fail for lack of a trustee.
When the trustee dies, the successor trustee is responsible for transferring the trust property into his own name as trustee. This usually requires the original death certificate and an affidavit of death of trustee, in which the successor states under oath that the prior trustee has died, that the prior trustee held the property, and that the successor is the person named in the trust document. With those papers, the county recorder (for real property) or the bank (for accounts) will transfer the property to the successor trustee.
If the trustee who died was also the grantor, the trust becomes irrevocable. Trust income can no longer be reported under the deceased grantor-trustee’s social security number, so the successor must obtain a tax identification number for the trust and file the returns that report the grantor’s income before death. Properties will also need to be appraised, so the successor should consult an accountant early.
The transition is a vulnerable period. Assets left unsecured can be lost, depleted or claimed by people with no right to them, so the successor should move in order:
The affidavit is the main document establishing the successor’s authority. It identifies the trust by name and date, identifies the original trustee and confirms the death, cites the trust provisions on succession, identifies the successor and confirms acceptance of the role, states that the trust is still in effect, and affirms the successor’s authority to act. It is notarized and recorded against any real estate the trust holds. Banks and brokerage firms often require their own forms in addition to the recorded affidavit.
The effect of a trustee’s death depends on the kind of trust.
| Type of trust | Effect of the trustee’s death |
|---|---|
| Revocable living trust (grantor is the original trustee) | The trust becomes irrevocable, because there is no longer a grantor to revoke it. The successor trustee takes over and administers the trust under its terms. |
| Irrevocable trust with the grantor as trustee | Less common. The grantor’s death does not change the trust’s irrevocable status; the successor simply takes over. |
| Irrevocable trust with a non-grantor trustee | Neither the status nor the terms of the trust change. The successor continues the administration. |
| Trust with co-trustees | The surviving co-trustee or co-trustees continue to serve. A successor is appointed if the trust requires a particular number of trustees. |
The deceased trustee’s social security number can no longer serve as the trust’s tax identification number. If the trust does not already have one, the successor applies for an Employer Identification Number, which can usually be done online through the IRS. Income earned before death is reported under the deceased’s social security number on the final returns; income earned afterward is reported under the new EIN. The successor should give the new number to every bank, brokerage and other payer so that 1099 forms are issued correctly.
Several returns may be due when a grantor-trustee dies.
| Return | What it covers |
|---|---|
| Final personal income tax return (federal Form 1040, New York IT-201) | Income from January 1 to the date of death |
| Initial trust income tax return (federal Form 1041, New York IT-205) | Income earned by the trust from the date of death forward |
| Federal estate tax return (Form 706) | Required if the gross estate exceeds the federal threshold ($15 million per person in 2026) |
| New York estate tax return (ET-706) | Required if the gross estate exceeds the New York threshold ($7.35 million for deaths in 2026) |
| Gift tax returns | Lifetime gifts that were never reported |
The successor trustee is generally responsible for the trust returns and, depending on the family situation, may also be responsible for the deceased’s final personal return. Coordination with the deceased’s executor and accountant matters.
Assets held in a revocable trust generally receive a step-up in basis to fair market value as of the grantor’s date of death. The successor trustee should obtain date-of-death appraisals of real estate, closely held business interests, and artwork, jewelry and other personal property; date-of-death values for marketable securities are easily obtained from the broker. These values become the trust’s basis going forward, and capital gain on a later sale is measured against the stepped-up basis, which is often far higher than the original cost.
After the transition, the successor has the same duties as the original trustee: investing under the prudent investor standard, distributing according to the trust’s terms, accounting to the beneficiaries periodically, filing trust tax returns each year, keeping records, keeping beneficiaries informed of material matters, and treating similarly situated beneficiaries impartially. These duties are fiduciary and carry personal liability for mistakes. Engaging counsel and adopting routine administrative practices reduces that exposure. A successor who wonders whether the trust terms can be changed will find the answer in can a successor trustee change a trust.
When the trust agreement names no successor, or every named successor is unable or unwilling to serve, any interested person (typically a beneficiary) may petition the court under SCPA § 1502 to appoint one. The court may appoint a successor when no other trustee is able to act or succeed and the trust still needs to be carried out, but it will not make an appointment that contravenes the express terms of the trust. The petition is served on all interested parties, a hearing is held if the appointment is contested, and the court then appoints a qualified individual or institution. Court-appointed trustees are typically professional fiduciaries, attorneys or institutional trustees rather than family members; the court weighs the candidate’s qualifications, the trust’s needs and the beneficiaries’ preferences.
