Executive Summary

Being named as a trustee or executor for a parent is a sign of trust — and the start of a job with real legal duties attached. The two titles are not interchangeable: an executor settles a will through the probate court, while a trustee manages assets held inside a trust, and one person is often asked to do both. This article walks through what each role requires, what "fiduciary duty" means for you personally, the tax filings you can't skip, and the mistakes that most often get well-meaning adult children into trouble.

First, Figure Out Which Job You Actually Have

A surprising amount of stress comes from people using these words interchangeably. They are three separate roles, governed by different documents, that switch on at different times.

Executor (also called personal representative)

An executor is the person named in a will to settle an estate after death. The executor's authority does not exist until the person dies and the probate court formally appoints them. Probate is simply the court-supervised process of proving a will is valid, paying the deceased person's debts and taxes, and distributing what remains. In New Jersey, the county Surrogate's Court handles this. Once appointed, the executor receives a document — often called Letters of Testamentary — that proves to banks, brokerages, and other institutions that you have the legal authority to act.

Trustee (and "successor trustee")

A trustee manages assets that were placed inside a trust. A parent who set up a revocable living trust typically served as their own trustee while healthy, then named a successor trustee — often an adult child — to step in when they became incapacitated or died. The key difference from an executor is timing and scope: a successor trustee can take over managing trust assets while the parent is still alive if the parent can no longer handle their own affairs, and trust assets generally pass to beneficiaries without going through probate at all.

Where power of attorney fits — and where it stops

Many adult children are also named as agent under a power of attorney (POA) — a document that lets you handle a parent's finances while they are alive but unable to do so themselves. Here is the piece people miss most often: a power of attorney ends the moment the person dies. It gives you no authority to settle the estate. At death, the baton passes to the executor (for probate assets) and the trustee (for trust assets). The diagram below shows how these roles hand off across a parent's life.

What "Fiduciary Duty" Means — And Why It Matters To You Personally

Executors and trustees are both fiduciaries, which means you are legally required to act in the interest of the estate or the beneficiaries rather than your own. That duty generally breaks down into a few obligations:

Duty of loyalty — no self-dealing. You cannot buy estate property at a discount, use trust funds for personal expenses, or favor yourself over other beneficiaries.
Duty of prudence — you must manage assets with reasonable care. For a trustee, this is often measured against the Uniform Prudent Investor Act, a standard most states have adopted that looks at how you managed the overall portfolio, not whether any single holding went up or down.
Duty of impartiality — if there are multiple beneficiaries (say, you and your siblings), you must treat their interests even-handedly, even when it's inconvenient.
Duty to account — you must keep clean records and report what you've done.

This is not just paperwork. A fiduciary who breaches these duties can be held personally liable — meaning out of their own pocket — for losses to the estate or trust. That is precisely why the boring habits below (separate accounts, receipts, written communication) protect you as much as anyone.

Core Responsibilities of the Executor

The exact sequence varies by state and by the size of the estate, but the arc of the job looks like this.

1. Locate the will and open probate

Find the original signed will, then file it with the county Surrogate's Court to be appointed. Order more certified copies of the death certificate than you think you'll need — most institutions want one, and you'll be contacting many.

2. Inventory and protect the assets

Build a complete picture of what the person owned and owed as of the date of death: bank and investment accounts, real estate, vehicles, personal property, life insurance, and any debts. Values are measured as of the date of death, which matters for both the accounting and the tax basis beneficiaries will inherit. Secure the property in the meantime — that can mean changing locks, maintaining insurance on a vacant home, or safeguarding valuables.

3. Notify and pay the right people, in the right order

You'll formally notify beneficiaries and known creditors. Legitimate debts and final expenses generally get paid before beneficiaries receive anything. Paying out to family too early — before you're certain the debts and taxes are covered — is one of the more common and costly missteps, because a shortfall can land on the executor personally.

4. Handle the taxes

More on the specific filings below, but the executor is responsible for making sure the final tax returns are filed, and any tax is paid from the estate.

5. Distribute what remains and close the estate

Once debts, expenses, and taxes are settled, you distribute assets according to the will, prepare a final accounting, and formally close the estate.

Core Responsibilities of the (Successor) Trustee

A trustee's work often looks less like a court proceeding and more like ongoing management, especially if the trust continues for years (for example, a trust that holds money for a beneficiary until a certain age).

Read the trust and take control of the assets

Your instructions live in the trust document — read it carefully, because it, not your own judgment about what's fair, controls what you may and may not do. Then get the assets retitled into your name as trustee so you can actually manage them. Assets the parent forgot to move into the trust may still have to go through probate, which is where an executor and trustee sometimes end up working side by side.

Manage prudently

Invest and administer the assets with reasonable care under the prudent-investor standard, keeping in mind the needs of both current and future beneficiaries. This is general fiduciary conduct, not a call to chase returns. This is also where a skilled financial advisor can be of assistance. If there are investment accounts in the name of the trust, as the trustee, you can select a financial advisor to assist in prudently managing those assets in accordance with the trust document.

Account to the beneficiaries

Beneficiaries are generally entitled to know what the trust holds and how it's being managed. Good recordkeeping helps prevent the misunderstandings that quietly turn into family disputes.

Distribute according to the trust — not according to you

Make distributions exactly as the document directs. If it says "for health, education, maintenance, and support," you don't get to substitute your own definition of a reasonable expense without understanding that standard.

The Taxes You Can't Afford To Overlook

Whether you're an executor or a trustee, tax deadlines don't pause for grief, and missing them can create penalties the fiduciary may have to answer for. Several separate returns can come into play:

The final individual return (Form 1040)

Someone has to file the parent's final personal income tax return for the year of death, covering income up to the date they died.

The fiduciary income tax return (Form 1041)

If the estate or trust earns income during administration — interest, dividends, rent — that income is reported on a fiduciary income tax return. You'll generally need to obtain a separate taxpayer ID (an EIN) for the estate or trust to do this.

The federal estate tax return (Form 706)

For 2026, the federal estate tax exemption is $15 million per person ($30 million for a married couple using portability), a level the One Big Beautiful Bill Act made permanent and indexed to inflation. Because that threshold is so high, the large majority of estates owe no federal estate tax. One nuance worth flagging: if a surviving spouse wants to preserve the deceased spouse's unused exemption (portability), a Form 706 may need to be filed even when no tax is owed. That's a conversation to have with a tax professional.

New Jersey's inheritance tax

Here's a state-specific point that trips up many central New Jersey families. New Jersey repealed its estate tax back in 2018, so people assume there's no state death tax left. But New Jersey is one of the few states that still imposes a separate inheritance tax, which is based on who inherits, not the size of the estate. The good news for most adult children: Class A beneficiaries — spouses, children, grandchildren, and parents — are fully exempt. Where it comes up is when a parent leaves money to a sibling, a niece or nephew, a friend, or an unmarried partner, who fall into a different beneficiary class. The return is generally due within eight months of death, and even fully exempt Class A estates may need a waiver form (such as the L-8) to release New Jersey bank and brokerage accounts. If any non-exempt beneficiary is in the picture, this is worth professional review.

One quiet piece of good news: the step-up in basis

Assets inherited at death generally receive a step-up in cost basis to their date-of-death value. In plain terms, if a parent bought stock decades ago for very little, the beneficiary's cost basis resets to what it was worth on the date of death — which can reduce the capital gains tax owed if the beneficiary later sells. It's one reason accurate date-of-death valuations (from step 2 above) matter well beyond the estate itself.

Five Mistakes That Create Real Liability

Commingling funds
Never run estate or trust money through your personal account. Open a dedicated account under the estate's or trust's EIN and keep every dollar separate.
Self-dealing
Buying assets from the estate, lending yourself money, or paying yourself an unreasonable fee invites challenge. Trustees and executors are generally entitled to reasonable compensation — just do it transparently and by the rules.
Distributing too early
Pay debts, expenses, and taxes first. Clawing money back from relatives after you've handed it out is painful and sometimes impossible.
Missing tax deadlines
The final 1040, the 1041, and any state filings all have due dates. Calendar them early.
Going it alone on a complex estate
Real estate in multiple states, a family business, blended-family beneficiaries, or a contentious family dynamic are all signs to bring in help rather than improvise.

When To Bring In Professionals

You don't have to be an expert — you have to be responsible, and part of being responsible is knowing when to delegate. An estate attorney handles probate and interprets ambiguous trust language; a CPA or Enrolled Agent handles the tax returns; and a financial professional can help you manage and eventually distribute the assets in line with the documents. Fees for reasonable professional help are generally payable from the estate or trust, not from your own pocket — so hiring qualified help is usually a matter of prudence, not extravagance

Frequently Asked Questions

Can I be both the executor and the trustee?

Yes, and it's common. Many parents name the same adult child for both roles. Just keep the two jobs — and the two pools of assets (probate assets versus trust assets) — clearly separate in your records, because they follow different rules and timelines.

Do I get paid for serving?

Executors and trustees are generally entitled to reasonable compensation, and states often provide guidelines for what "reasonable" looks like. Some family members waive the fee; others don't. Be aware that fees you receive are typically taxable income to you, so factor that in before deciding.

What if my parent named me but I don't want to serve?

You can generally decline before you accept the role, and in most cases you can resign afterward through the proper legal process — though resigning mid-stream is more involved. If a successor or co-fiduciary was named, they may step in. This is a reasonable question to raise with an attorney rather than something to figure out alone.

Does having a trust mean we avoid probate entirely?

Only for the assets actually titled in the trust's name. A common surprise is discovering that a parent set up a trust but never moved a particular account or property into it. Those "loose" assets may still pass through probate, which is often why an executor and a trustee end up working together.

Talk It Through Before You're in the Middle Of It

The hardest time to learn this job is while you're grieving and the clock is already running. If you've been named as a trustee or executor for a parent — or you're a parent deciding whom to name — a conversation now can prevent a great deal of confusion later.
