Executor: Definition and How It Works in California

By Eric Ridley, attorney, Ridley Law. Updated September 2026.

An executor is the person a will names to carry out its instructions: filing for probate, collecting the decedent’s assets, paying debts, and distributing what’s left to the beneficiaries.

How it works in California

An executor has no authority just because a will names them. Under Prob. Code, § 58, an executor is a type of personal representative, and under Prob. Code, § 8400, that person has no power to act for the estate until the probate court appoints them and issues letters testamentary. For a fuller walk-through of what the job involves day to day, see the executor’s role in a California will.

Once appointed, the executor’s job runs through the entire probate process: locating and valuing assets, notifying creditors and beneficiaries, paying valid debts and taxes, and eventually petitioning the court to close the estate and distribute what remains. Executors typically post a probate bond unless the will waives it or every beneficiary agrees to waive it in writing, and the court can still require one.

California doesn’t require an executor to live in the state, but an out-of-state executor still has to work within the California probate court’s timeline and filing rules. Executors also owe the estate a fiduciary duty: acting in the beneficiaries’ interest, keeping estate money separate from personal funds, and accounting for what comes in and goes out.

Why it matters

For example, an out-of-state sibling named as executor sometimes assumes the title alone lets them access the decedent’s bank accounts. It doesn’t. Until the court issues letters testamentary, the bank has no obligation to talk to them, and moving money before appointment can create personal liability. The gap between being named in a will and actually having authority to act is where most executor problems start.

Common mistakes

Acting before letters testamentary are issued, which can expose the executor to personal liability. Mixing estate funds with personal accounts instead of opening a separate estate account. Assuming the job ends at distributing assets rather than also handling final tax returns and a full accounting to the beneficiaries.
