Executor of a Trust vs. Executor of a Will: What Adult Children Need to Know

When a parent sets up a living trust alongside a will, two separate roles need to be filled — and many families confuse them. The executor (sometimes called a personal representative) handles the will. The trustee handles the trust. These are different jobs, different legal authorities, and different timelines.

Understanding both roles helps you have a better conversation with your parent about who should fill them, and prepares you if you are ever asked to serve in either capacity.

The Executor: Will-Based Authority

An executor is named in the will and derives authority from the probate court. When your parent dies, the executor files the will with the court, applies for "Letters Testamentary" (or their state's equivalent), and uses that court-issued authority to collect assets, pay debts, and distribute what remains to beneficiaries.

The executor's authority is time-limited and court-supervised. The probate process typically takes 9 to 18 months. Once it concludes, the executor's job ends. The role is a temporary one.

Key executor responsibilities include:

• Filing the will with the probate court and opening the estate
• Notifying creditors and paying valid debts (including final tax returns)
• Gathering and securing all probate assets
• Distributing assets to beneficiaries per the will
• Closing the estate with the court

An executor only handles probate assets — assets that do not have a beneficiary designation, are not held in a trust, and are not jointly owned with right of survivorship. If your parent has a fully funded living trust, there may be very little going through probate at all.

The Trustee: Trust-Based Authority

A trustee manages assets held inside a trust. For a revocable living trust, the parent typically serves as their own trustee during their lifetime — they maintain full control of the trust assets. They also name a successor trustee who steps in when they become incapacitated or die.

Unlike an executor, the successor trustee does not go through court. Their authority comes from the trust document itself. This is one of the main advantages of a living trust: it allows someone to manage or distribute assets without probate, without court supervision, and without the public record that probate creates.

Key successor trustee responsibilities include:

• Stepping in when the parent loses capacity (without waiting for death — this is critical)
• Managing trust assets for the benefit of the parent during incapacity
• After the parent's death, distributing trust assets to beneficiaries per the trust terms
• Keeping accounting records and acting as a fiduciary at all times
• Potentially managing an ongoing trust if it continues for minor grandchildren or other beneficiaries

The trustee's role can be longer-term than an executor's. If the trust holds assets for beneficiaries over multiple years — for example, holding a grandchild's inheritance until age 25 — the trustee manages those assets for the full duration.

The Critical Difference: Incapacity

The most underappreciated difference between the two roles is when they become active.

An executor has no authority until the parent dies. The executor cannot access accounts, pay bills, or make decisions during a period of incapacity.

A successor trustee, by contrast, can step in when the parent becomes incapacitated — while still alive. If your parent has a stroke and can no longer manage their finances, the successor trustee named in the living trust can immediately take over management of the trust assets. No court petition required, no waiting.

This is why a properly funded living trust combined with a durable power of attorney gives families much stronger protection than a will alone. The will only speaks after death. The trust and power of attorney cover incapacity.

Can the Same Person Serve as Both?

Yes, and this is common. Your parent can name you as both executor (in the will) and successor trustee (in the trust). You would handle both the trust administration and any probate assets simultaneously.

Whether this makes sense depends on:

• The size and complexity of the estate. Simple estates with one trustee/executor are manageable. Complex estates with business interests or ongoing trusts may benefit from separating the roles or using a professional trustee for one.
• Family dynamics. If naming one sibling creates conflict, naming a neutral third party as trustee for ongoing distributions can reduce friction.
• The individual's skills. A trustee managing investments over years needs different skills than an executor wrapping up an estate in 12 months.

Choosing the Right Person

When helping your parent think through who to name, focus on these qualities:

For the executor:

• Organized and detail-oriented
• Available for 12-18 months during probate
• Lives in or near the same state (out-of-state executors sometimes face additional requirements)
• Trusted to be fair to all beneficiaries
• Not easily intimidated by paperwork and legal correspondence

For the successor trustee:

• Financially responsible and trustworthy
• Capable of making investment decisions or willing to hire a professional
• Available to step in quickly during an emergency (incapacity)
• If the trust continues beyond death for multiple beneficiaries, able to remain impartial over years
• Willing to take on the fiduciary duty — this is a legal obligation to act in the beneficiaries' best interests, not their own

When to consider a professional trustee: If the trust holds substantial assets over a long period, especially for younger grandchildren or for a surviving spouse with cognitive issues, a corporate trustee (bank trust department or trust company) can serve. They charge fees — typically 0.5% to 1% of trust assets annually — but bring professional investment management and eliminate the burden from family members.

Common Mistakes to Avoid

Naming someone without asking them first. Being named as executor or trustee is not an honor — it is a significant time commitment and legal responsibility. Always ask before naming someone.

Naming only one successor trustee with no backup. Life happens. Name a primary successor trustee and at least one alternate in case the first is unable to serve.

Not updating the trust after major life events. If the named trustee dies, moves, becomes ill, or has a falling out with the family, the trust should be amended. An outdated trust that names someone who is now dead or estranged creates serious problems.

Failing to fund the trust. A living trust that holds no assets is a legal shell. Assets must be retitled into the trust's name for the trust to control them. A common mistake is setting up the trust but never transferring the home, bank accounts, or investments into it. The executor ends up handling probate on assets that were supposed to pass through the trust.

Assuming the trustee knows what to do. The trust document governs the trustee's actions, but a new trustee often needs legal guidance during the first administration. Budget for an attorney's help during the transition.

What This Means for Your Family

If your parent has a living trust, find out:

1. Who is named as successor trustee?
2. Is there an alternate?
3. Does the named trustee know they have been selected and understand the role?
4. Is the trust properly funded — does it actually hold the assets it was designed to hold?

These questions cost nothing to ask and can prevent enormous problems later. A trust that names the right trustee but holds no assets, or a trustee who is surprised by the role at the worst possible moment, is a plan that will fail in practice even if the documents are perfect on paper.

Keeping Track of It All

Between the will, the trust, the executor, the successor trustee, powers of attorney, and beneficiary designations, there is a lot to document. The End-of-Life Planning Workbook includes a Document Locator worksheet specifically designed to record where each legal document is kept, who has been named in each role, and what contact information is needed for each person.

When a parent becomes incapacitated or dies, the last thing a family needs is a scavenger hunt for paperwork. Having a single, organized reference that covers all roles and document locations is the foundation of a plan that actually works.
