After the grantor dies, a revocable trust becomes irrevocable and shifts from a flexible planning tool into a fixed set of instructions that the successor trustee carries out. That trustee gathers the assets, notifies beneficiaries, pays debts and taxes, and then distributes what remains, all outside of probate court. Understanding how a revocable trust works after the grantor dies matters because the process usually takes somewhere between six months and two years, and the trustee’s decisions along the way can either protect the family or create real liability.
The Trust Locks the Moment the Grantor Dies
During the grantor’s lifetime, a revocable trust is essentially an extension of the grantor, who can rewrite it, pull assets out, or dissolve it entirely. Death ends that flexibility. The terms are now fixed, and no one has authority to change them.1Internal Revenue Service. Certain Revocable and Testamentary Trusts That Wind Up
Two practical consequences follow. The trust is now its own legal entity for tax purposes, separate from the grantor and from the grantor’s estate, which means it needs its own taxpayer identification number and its own tax returns going forward. And the assets inside belong to the trust itself. The successor trustee manages them under the document’s instructions but does not own them.
The Successor Trustee Steps In
The person or institution named as successor trustee now takes over. The role carries a fiduciary duty, the highest standard of care the legal system recognizes. In plain terms, the trustee has to put the beneficiaries’ interests ahead of their own in every decision.
That duty breaks into a few core obligations. Loyalty means the trustee cannot use trust assets for personal benefit or engage in self-dealing. Prudence means investment and management decisions must be reasonable; a trustee who gambles trust funds on speculative investments or lets property fall into disrepair can be held personally liable. Impartiality means that when a trust has multiple beneficiaries, the trustee has to balance their interests fairly according to the trust’s terms rather than play favorites.
Accepting the role is voluntary. Most trust documents include a provision for declining, and the trustee usually signs a formal acceptance of trusteeship before taking any action. If the named successor cannot or will not serve, the document typically names an alternate or gives a mechanism for appointing one.
First Steps for the Trustee
Getting organized comes before everything else. The most important document is the original signed trust agreement, along with any amendments the grantor made during their lifetime, since those modify the original terms.
Next comes ordering certified copies of the death certificate. Banks, brokerages, insurance companies, and government agencies all require certified copies to verify the death and to recognize the successor trustee’s authority. Ordering a dozen or more up front saves repeat requests later.
Beneficiaries then have to be notified in writing. Most states require notice within a set period after the grantor’s death, often around 60 days, though the exact window varies. The notice generally covers the trust’s existence, the beneficiary’s interest, the trustee’s identity and contact information, and the beneficiary’s right to request a copy of the trust document. Skipping or delaying this step can expose the trustee to legal liability and give beneficiaries grounds to challenge the administration.
Inventorying and Valuing the Assets
The trustee has to build a complete inventory of everything the trust owns: bank accounts, investment portfolios, real estate, business interests, vehicles, valuable personal property, debts owed to the trust, and liabilities the trust owes.
Many assets need professional appraisals as of the grantor’s date of death. Real estate, closely held businesses, and collectibles all require formal valuations. Those appraisals do two things: they set the estate’s total value for potential tax obligations, and they establish the new tax basis for inherited assets.
Why the Stepped-Up Basis Matters
Under federal law, when someone inherits property through a revocable trust, the tax basis of that property resets to its fair market value on the date the grantor died. If the grantor bought a house for $150,000 and it was worth $500,000 at death, the beneficiary’s basis becomes $500,000. Sell the house for $510,000, and only the $10,000 gain is taxable, not the $350,000 gain the grantor would have faced.2Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
This works because assets in a standard revocable trust are included in the grantor’s taxable estate. Getting the date-of-death appraisals right is essential. Without documented valuations, beneficiaries may struggle to prove their stepped-up basis to the IRS if they later sell.
Paying Debts Before Anyone Gets a Distribution
The trustee has to pay the grantor’s outstanding debts, final medical bills, funeral expenses, and the costs of administering the trust itself before distributing anything. A trustee who hands out assets to beneficiaries while legitimate debts remain unpaid can be held personally liable for those debts.
Creditor claims against a trust work differently from claims in probate. Probate has a formal creditor notice process and a clear deadline after which claims expire. Trusts vary significantly by state. Some states impose a statutory period, often one year, during which creditors can pursue claims against trust assets. Others are less structured. Because of that uncertainty, experienced trustees typically wait for the applicable creditor claim period in their state to run before making final distributions. Rushing this step is one of the most common and costly mistakes.
The Tax Filings
The tax side catches many successor trustees off guard. There can be three separate filings, and a new taxpayer ID is the starting point.
A New EIN for the Trust
Once the grantor dies, the trust can no longer use the grantor’s Social Security number. The trustee applies for a new Employer Identification Number from the IRS, which can be done online. That EIN identifies the trust as its own taxpayer going forward.3Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1
The Grantor’s Final Form 1040
The trustee is responsible for the grantor’s final personal income tax return, covering January 1 of the year of death through the date of death. The return is due by the normal April 15 deadline of the following year. A surviving spouse may file jointly for that final year.
The Trust’s Form 1041
Any income earned by trust assets after the date of death is reported on the trust’s own Form 1041. The trust pays tax on income it retains and passes through a deduction for income distributed to beneficiaries, who then report it on their personal returns. Calendar year trusts file by April 15 of the following year.4Internal Revenue Service. About Form 1041 US Income Tax Return for Estates and Trusts
The trustee and the estate’s executor can jointly elect under Section 645 of the tax code to treat the revocable trust as part of the grantor’s estate for income tax purposes. The election lets the trust use the estate’s fiscal year instead of a calendar year, which can defer income and add flexibility. It must be made on the first Form 1041 filed for the estate, and once made it cannot be undone.5Office of the Law Revision Counsel. 26 USC 645 – Certain Revocable Trusts Treated as Part of Estate
Federal Estate Tax and Portability
If the total value of the grantor’s estate, including trust assets, exceeds the federal estate tax exemption, the trustee or executor files Form 706. For 2026, the exemption is $15,000,000 per individual.6Internal Revenue Service.

Skipping the portability election when a spouse survives can cost the family significant future estate tax savings.7Internal Revenue Service. Instructions for Form 706
Distributing What’s Left
Distribution comes last for good reason. The trustee should only distribute after confirming that debts have been paid, tax returns have been filed or adequate reserves set aside, and the creditor claim period in the relevant state has run.
Before making distributions, the trustee prepares a final accounting showing every transaction during administration: assets collected, income earned, debts paid, fees incurred, and the remaining balance. Beneficiaries are entitled to review it, and getting their written approval before distributing protects the trustee from later claims that the administration was mishandled.
The trust document controls how assets go out. Some beneficiaries receive outright distributions and take full control of their share immediately. Others receive their inheritance through a continuing trust, where assets stay in trust and are distributed over time under conditions the grantor set, such as staggered age-based payments (a third at 25, a third at 30, the rest at 35) or a trust that pays out only income while preserving the principal for the next generation.
Once assets are distributed and beneficiaries have signed receipts, the trustee can formally close the trust. Simple estates with straightforward terms can wrap up in six to nine months. Complex assets, tax issues, or family disputes can stretch administration well beyond two years.
Assets the Grantor Never Put Into the Trust
A revocable trust only controls assets that were actually transferred into it during the grantor’s lifetime. Anything the grantor forgot to retitle, acquired after creating the trust, or never got around to moving in remains outside the trust and may have to go through probate.
Most estate plans that include a revocable trust also include a pour-over will, which directs that any assets owned in the grantor’s individual name at death be transferred into the trust. Those assets still have to pass through probate before reaching the trust, which partially defeats the probate-avoidance purpose. Without a pour-over will, assets left outside the trust pass under the state’s default inheritance laws, which may not match what the grantor intended.
The assets people most commonly forget to retitle include newly opened bank accounts, vehicles, real estate purchased after the trust was created, and tax refunds owed to the deceased.
Whether Beneficiaries Can Challenge the Trust
Trusts are not bulletproof. Beneficiaries and disinherited heirs can challenge a revocable trust after the grantor’s death on several grounds. The most common are lack of mental capacity, meaning the grantor did not understand what they were signing; undue influence, meaning someone pressured or manipulated the grantor into terms that benefit that person at the expense of natural heirs; and fraud or forgery, meaning the document was falsified or the grantor was deceived about its contents.
Many trust documents include a no-contest clause, which threatens to disinherit anyone who challenges the trust and loses. These clauses are enforceable in most states, though their teeth vary. A beneficiary with a substantial inheritance at stake will think twice; someone left nothing has nothing to lose. Challenges typically must be filed within a limited window after the beneficiary receives notice, often 120 days, though this varies by state.
What Administration Costs
Trust administration is not free. Attorney fees for guiding a successor trustee through the process typically range from $150 to $800 per hour depending on the market and the complexity of the estate. Simple administrations might require only a few hours of legal time. Contested or tax-heavy estates can generate substantial legal bills.
If the trust holds real estate or other hard-to-value assets, professional appraisals run from a few hundred dollars for a standard residential property to $10,000 or more for complex commercial real estate or business interests. Accounting fees for the fiduciary tax returns add another layer.
When a professional or corporate trustee serves rather than a family member, fees typically run between 1% and 3% of the trust’s total assets and are paid from the trust before beneficiaries receive their shares. Even when a family member serves, many trust documents authorize reasonable compensation, though family trustees frequently waive it.
