In probate law, an administrator is a person appointed by a California probate court to act as the estate’s personal representative when no qualified executor is available. The administrator collects and protects probate assets, pays valid debts and taxes, handles probate filings, and distributes the remaining property under the will or California intestate succession law, depending on the case.
What Is an Administrator of an Estate?
An administrator is a person appointed by the probate court to administer a decedent’s estate when the decedent dies without a valid will, or when no named executor is willing, able, or eligible to serve. Like an executor, an administrator is responsible for managing the estate, paying debts, and distributing assets.
In California probate, both an administrator and an executor are types of personal representatives. The main difference is how the person is selected and whether the estate is governed by a will, intestate succession law, or a will where no executor can serve.
An administrator generally manages an intestate estate and distributes the remaining probate assets under California’s intestate succession laws. If a valid will exists but no executor is named, willing, or able to serve, the court may appoint an administrator with the will annexed, who administers the estate according to the will.
When Does a California Probate Court Appoint an Administrator?

A California probate court may appoint an administrator when estate administration is needed and there is no qualified executor available to serve. Common situations include:
- The decedent died without a valid will;
- The will does not name an executor;
- The named executor declines to serve;
- The named executor is unable, unavailable, or ineligible to serve; or
- A dispute exists over who should administer the estate.
The process usually begins with a Petition for Probate. After appointment, the court issues Letters of Administration or, where a will exists but no executor can serve, Letters of Administration with Will Annexed.
Who Has Priority to Serve as Administrator in California?
California law gives certain people priority to serve as administrator. The preferred order generally starts with the surviving spouse or registered domestic partner, then children, grandchildren, other heirs, parents, siblings, more remote relatives, the Public Administrator, creditors, and eventually other persons.
A person outside the preferred family priority classes may petition for appointment, but that does not give the person equal priority. The court considers California’s statutory order of priority, any nominations or waivers, the petitioner’s eligibility, and whether the appointment would protect the estate.
A Public Administrator is a county official who may administer an estate when no appropriate private person is available, willing, or entitled to serve.
Who Can Serve as an Administrator?
A proposed administrator must be legally competent to serve. California generally disqualifies minors, people who are incapable or unfit to perform the duties, people subject to certain conservatorships, and some non-U.S. residents. Having appointment priority does not guarantee that the court will appoint the person.
The court may also require the administrator to obtain a probate bond before Letters of Administration are issued. The bond protects heirs, beneficiaries, creditors, and the estate against losses caused by mismanagement or misconduct. Exceptions or waivers may apply depending on the facts and governing documents.
When Does an Administrator’s Authority Begin?
An administrator’s authority begins when the probate court appoints the person and issues Letters of Administration. A court order approving the appointment alone is not enough; the appointment does not become effective until the letters are issued.
Letters of Administration are the court-issued document that gives the administrator authority to act for the estate. Banks, title companies, buyers, creditors, and other third parties often require letters before recognizing the administrator’s authority.
What Does an Administrator Do?
An administrator is responsible for administering the estate throughout the probate process. Typical duties include:
- Identifying, collecting, and protecting probate assets;
- Managing and preserving estate property;
- Preparing and filing an Inventory and Appraisal;
- Working with a probate referee where an appraisal is required;
- Notifying creditors and evaluating creditor claims;
- Paying valid debts, taxes, and administrative expenses;
- Obtaining a tax identification number when needed and handling required tax filings;
- Maintaining records of estate income, expenses, and transactions;
- Preparing required probate filings, reports, and accountings; and
- Petitioning for final distribution and transferring remaining estate assets.
When a person dies without a valid will, estate assets are distributed under California Probate Code sections 6400–6414. Depending on the decedent’s surviving family members, the estate generally passes to the surviving spouse or registered domestic partner, children or descendants, parents, siblings, or more remote relatives.

What Fiduciary Duties Does an Administrator Owe?
Once appointed, the administrator owes fiduciary duties in managing the estate. An administrator must act in the estate’s interests, safeguard assets, avoid self-dealing, treat interested parties fairly, maintain accurate records, and comply with court orders.
An administrator who breaches these fiduciary duties may be removed by the court and held personally liable for resulting losses. In probate litigation, fiduciary-duty disputes often involve alleged mismanagement, failure to account, improper distributions, conflicts of interest, or misuse of estate property.
Can an Administrator Manage or Sell Estate Real Property?
An administrator may be authorized to manage or sell estate real property, but the required procedure depends on the powers granted by the probate court. A sale may require court confirmation or compliance with California’s Independent Administration of Estates Act, including a Notice of Proposed Action.
This issue often matters when the estate includes valuable California real estate, disputed occupancy, unpaid property expenses, or competing heirs. Schorr Law’s related guide on selling inherited property discusses additional issues that can arise when estate property needs to be sold.
Administrator vs. Executor
Administrators and executors perform many of the same probate functions. The main difference is how they are selected and what document gives them authority.

Common Disputes Involving Administrators
Issues involving administrators frequently arise in probate litigation, including:
- Contested appointments;
- Competing petitions to serve as administrator;
- Alleged breaches of fiduciary duty;
- Disputes involving the sale or management of estate real property;
- Heirship and intestate succession disputes;
- Failure to account or disclose estate transactions; and
- Claims involving self-dealing, conflicts of interest, or mismanagement.
These issues often become more complex when the estate includes valuable real property or multiple competing heirs. Schorr Law has handled disputes and trials involving competing petitions for appointment as administrator of an estate.
Can an Administrator Be Removed?
A California probate court may remove an administrator for mismanagement, fraud, embezzlement, wrongful neglect, incapacity, failure to perform required duties, or when removal is necessary to protect the estate or interested persons.
Removal does not necessarily end the dispute. The court may need to appoint a successor personal representative, require an accounting, address surcharge claims, or resolve disputes over estate property.
If a dispute involves the appointment, authority, removal, or conduct of an administrator, Schorr Law’s Los Angeles probate attorneys can evaluate the probate and real-property issues involved.
