Attorney, trust company or family: who should act for you?

Updated 2026-10-16 · Expert review in progress

The short answer

Family fits when someone close is willing, able and nearby, and your affairs are simple. An attorney fits when the estate has legal complexity and you want a known adviser. A trust company fits when you need someone neutral who will outlast you and stay available. Many plans combine them, with family first and a professional as backup.

When you sit down to name an executor or a trustee, three kinds of candidates usually come up. A family member. The lawyer who helped with your will. Or a trust company, whose business is serving in these roles.

Each brings something real, and each has limits. This page compares them plainly so you can match the right one to each job. It is part of our guide to choosing professional help.

What each option actually is

A family member is a sister, son, niece or cousin you name in your documents. Family is also who the law picks by default when you name nobody, which is a separate question covered in default decision-maker laws by state.

An attorney can be named in their own name, like any qualified person. In Washington, a firm owned only by attorneys and organized under state law can also serve as an executor (RCW 11.36.010). Separately, any executor can hire an attorney for the legal work, without making the attorney the executor.

A trust company is a regulated firm that serves as executor, trustee or agent. Washington allows trust companies organized under its laws, and authorized national banks, to serve as executor even though most corporations can't (RCW 11.36.010). Washington trust companies are supervised by the state Department of Financial Institutions (RCW 30B.04.005).

All three, once named, are fiduciaries. That means legally required to act in your interest and follow what you wrote.

For the pay row, Washington's rules are specific. An executor gets what the will sets, or what a court finds just and reasonable, and may be allowed more for legal work (RCW 11.48.210). An agent under a power of attorney is entitled to reasonable pay unless the document says otherwise (RCW 11.125.120). For what professionals tend to charge, see trust company fees and estate planning attorney cost.

When family is the right choice

Family can be the best choice, and often the warmest. Lean toward family when:

  • Someone is willing, organized and younger than you
  • They live close enough to get to the house or the hospital
  • Your estate is simple, with few accounts and no business
  • Your heirs get along, or the family member isn't one of them

The hard part with family is often timing. A brother your own age may be unwell when the day comes. A child three time zones away can sign papers but can't check the furnace.

Naming family on purpose still beats leaving it to the default. Say you haven't named a health care agent in Washington, and you have several adult children. The medical consent law then requires all available children to agree (RCW 7.70.065). One named person avoids that.

When an attorney is the right choice

An attorney may be the right executor or trustee when the legal work is the hard part. That might mean property in several states, a business, or an heir likely to contest the will.

Before naming your lawyer, ask a few things:

  • Are you willing to serve, and what will you charge?
  • Who takes over if you retire or leave the practice?
  • Would you rather serve as executor, or advise whoever does?

For many estates, it works well to name a family member or trust company as executor and have them hire a lawyer for probate. The lawyer handles the court; the executor handles the rest.

When a trust company is the right choice

A trust company tends to fit when continuity and neutrality matter most. Think of a trust that will run for years, heirs who may not agree, or a plan where the people you'd name are your age.

A trust company is an institution, so the staff you deal with may change over time. Its knowledge of you comes from your file, which is why a written plan matters so much. Our page on corporate vs individual trustees goes deeper on that trade-off.

Questions to ask any trust company:

  • Who regulates and examines you?
  • What do you charge, and when does billing start?
  • Will you serve in powers of attorney, or only as executor and trustee?
  • Can you serve as backup behind a family member?

Mixing them is often the answer

You don't have to pick one for everything. Each role can have its own choice.

RoleOne way to fill it
Medical power of attorneyA family member or close friend first, a professional as backup
Financial power of attorneyA family member or a trust company, with the other as backup
ExecutorA family member or trust company, who hires an attorney for probate
TrusteeA trust company, especially for a trust that will run for years

If you name two agents to serve together under a power of attorney, Washington's default is that they must act jointly unless the document says otherwise (RCW 11.125.110). You may prefer one at a time, with the second as backup. That arrangement, with a professional waiting behind the first choice, is what we call a standby fiduciary.

Where Kinly fits

Kinly is one version of the trust company option. A membership names Trella Trust Company, a Washington State chartered trust company, in any or all four roles. It can be first, or backup to family or friends. If the trust company actually steps in and does work, it is charged by the hour, and you see the rates before anything starts. If your estate needs a litigator or a family-business specialist, a private attorney may serve you better. The two can work together. More on how it works, and on naming a friend vs a professional.

Common questions

Should my lawyer, a trust company, or a family member be executor?

Choose family if someone close is willing, able and nearby and the estate is simple. Choose an attorney if the legal work is complex. Choose a trust company if you want a neutral party that will be there decades from now. Naming one first and another as backup is often the most practical plan.

Can a trust company be executor in every state?

Rules vary by state. In Washington, trust companies organized under state law and authorized national banks may serve, while most other corporations may not. Check your own state's law, or ask the trust company where it can serve.

Is a family member cheaper than a professional?

Often, because many family members waive pay. But a family executor may still need to hire a lawyer or accountant, and the estate pays for that. In Washington, a family member serving as agent or executor is also entitled to reasonable pay if they want it.

What happens if the family member I name can't serve?

If you named a backup, the backup steps in. If you didn't, the law decides. In Washington, when every named executor refuses, the court appoints whoever would have been entitled with no will at all (RCW 11.28.010).
