Quick answer
A successor trustee's core duties are to notify beneficiaries, get a tax ID and open a trust bank account, inventory and protect the trust's assets, pay the deceased's debts and taxes, and then distribute what remains to beneficiaries per the trust — all without going through probate court. You generally act using the trust document itself, not a court order.
If someone named you successor trustee of their living trust, your job starts the moment they die or become incapacitated — usually with no court involved at all. That's the whole point of a trust, but it also means there's no judge walking you through the process. Here's what you actually need to do, in order.
What Is a Successor Trustee?
While the person who created the trust ("the grantor") is alive, they usually serve as their own trustee, keeping full control of their assets. The successor trustee is the backup named in the trust document who steps in when the grantor dies or can no longer manage their own affairs.
Your job is to:
- Locate, protect, and inventory the trust's assets
- Pay the deceased's valid debts, expenses, and taxes
- Distribute what remains to beneficiaries according to the trust's instructions
- Keep accurate records and communicate with beneficiaries throughout
Successor Trustee vs. Executor
These roles are often confused because the same person frequently holds both.
- An executor is named in a will and administers assets that go through probate court.
- A successor trustee is named in a trust and administers assets the grantor already transferred ("funded") into the trust — without probate.
If the grantor used a trust as their main plan with a simple "pour-over" will as a backstop, you may be both executor and successor trustee: executor for any stray assets outside the trust, trustee for everything inside it. See our executor duties checklist if you're handling both roles.
Your Duties as Trustee
As trustee, you hold a fiduciary duty to the beneficiaries, meaning you must:
- Act in their interest, not your own
- Follow the trust's terms exactly as written
- Keep trust and personal funds separate at all times
- Keep beneficiaries reasonably informed and provide accountings when asked
Step-by-Step Checklist
1. Accept the Role and Read the Trust
Get the original, signed trust document (and any amendments) and read it fully before doing anything else. It defines your authority, lists the beneficiaries, and spells out exactly how assets should be distributed.
2. Notify Beneficiaries
Most states require the successor trustee to send beneficiaries and heirs a formal notice within a set window after the death. Even where it isn't strictly required, notifying beneficiaries early avoids disputes later.
3. Get an EIN and Open a Trust Account
The trust typically needs its own tax ID (EIN) from the IRS once the grantor dies. Use it to open a dedicated trust bank account — never run trust money through your personal accounts.
4. Inventory and Secure the Assets
List everything the trust holds and confirm it was actually retitled into the trust's name — real estate, bank and brokerage accounts, and valuable personal property. Assets the grantor forgot to transfer may need to go through probate separately. Maintain insurance, pay the mortgage and property taxes, and safeguard valuables while you administer the trust.
5. Pay Debts, Expenses, and Taxes
Pay the deceased's valid debts and final expenses from trust funds, file their final personal income tax return, and file a trust income tax return for any income the trust earned after death. Consult a tax professional if the estate is large or the trust structure is complex.
6. Distribute Assets
Once debts, expenses, and taxes are handled, distribute the remaining assets to beneficiaries exactly as the trust directs — whether that's an outright distribution, staged payments over time, or funds held in further trust for a minor.
7. Provide a Final Accounting and Close the Trust
Give beneficiaries a final accounting of what came in, what was paid out, and what was distributed. Once everything is settled, close the trust's accounts and your role ends.
Common Trustee Mistakes
- Commingling funds. Always keep trust money in its own account, separate from your personal finances.
- Distributing too early. Settle debts and taxes first — you can be personally liable if you distribute early and a valid claim shows up later.
- Ignoring the trust's exact terms. Follow the document as written, even if you'd personally handle something differently.
- Skipping records. Keep receipts and a running accounting; beneficiaries can request one, and disputes are far easier to resolve with documentation.
- Missing tax filings. Trust and final personal tax returns have real deadlines — don't assume "no probate" means "no paperwork."
This is general information, not legal or tax advice — trustee rules vary by state and by the terms of the specific trust, so consult an estate attorney for anything complex or contested.
