California Probate Notice of Hearing: Recipients, Deadlines, and Service

A California probate notice of hearing must reach every required party at least 15 days before the hearing date, delivered by first-class mail, personal delivery, or (with written consent) electronic service, with proof of service filed before the judge calls the matter. The petitioner is responsible for identifying who gets notice, picking an approved method, and documenting it. Any gap on those three fronts tends to push the hearing out.

Who You Have to Notify

For a petition to probate an estate, Probate Code 8110 requires notice to every known heir of the decedent and to every devisee, executor, and alternative executor named in any will offered for probate, even if a later document purports to revoke that appointment or gift.¹ Heirs must be identified “so far as known to or reasonably ascertainable by the petitioner.” You cannot skip a relative you have lost touch with without making a real effort to find them.

If the decedent died without a will, notice must reach everyone who would inherit under California’s intestate succession rules.² If the decedent was a citizen of a foreign country, or if estate property will pass to a foreign citizen, notice must also go to the recognized diplomatic or consular official of that country who maintains an office in the United States.³

For later hearings in the same case (accountings, distribution requests, sale approvals, and similar matters), Probate Code 1220 sets a narrower default list: the personal representative of the estate and anyone who has filed a request for special notice under Probate Code 1250.⁴ Many individual statutes expand that list for particular hearing types, so check the specific code section governing your petition rather than relying on the default.

The 15-Day Deadline

Notice has to go out at least 15 days before the hearing.⁴ The clock starts when you mail or deliver the notice, not when the recipient opens the envelope. The Probate Code explicitly declines to extend the notice period to account for mailing time, so if a recipient lives out of state or overseas, it is wise to mail earlier than the minimum. A recipient who never actually sees the notice before the hearing can create problems later even if the paperwork was technically on time.

For good cause, the court can shorten the notice period, but only sparingly and only when the statute governing your petition allows it. Some proceedings (conservatorship-related petitions, for example) run on different timing rules in a separate part of the code. Confirm the period that applies to your specific petition rather than assuming 15 days is universal.

How Notice Can Be Delivered

Probate Code 1215 recognizes three delivery methods, each with its own rules.⁵

First-class mail (including certified, registered, or express mail) in a sealed, postage-paid envelope addressed to the recipient’s residence or place of business. International mail services qualify for recipients outside the country. Mailing is complete when the envelope is deposited.
Personal delivery, complete the moment the notice reaches the recipient. The server must be at least 18 and not a party to the proceeding.
Electronic delivery, available only if the recipient has filed express consent (Judicial Council Form EFS-005-CV) and provided an email address for that purpose. Filing documents electronically is not consent to receive electronic service. A party can withdraw consent at any time by filing Form EFS-006.

One rule catches petitioners off guard: if you are the petitioner, you cannot mail the notice yourself. A non-party must handle the mailing and sign the proof of service.³

Requests for Special Notice

Any person with an interest in the estate (heir, devisee, creditor, or trust beneficiary) can file a written request for special notice with the court clerk at any time after letters have been issued.⁶ The request lists the person’s mailing address and the types of filings they want to be told about: petitions, inventories and appraisals, objections to appraisals, accountings, and status reports.

Once a valid request is on file, the petitioner must send that person written notice of every covered filing, along with a copy of the petition, account, or other document, at least 15 days before the hearing.⁶ The obligation continues through every subsequent hearing that falls within the scope of the request. Overlooking a special notice request is one of the most common reasons hearings get continued, because the court will check.

When a Required Recipient Cannot Be Found

The Probate Code does not let a missing heir stall the case forever, but it does require a real effort before alternatives are allowed. A diligent search typically includes contacting other known relatives, checking last known addresses, searching property records, reaching out to former employers, and searching online resources including social media. A private investigator may be appropriate in difficult cases. Whether the effort qualifies as reasonable is within the court’s discretion.

If those efforts fail, the court can authorize service by publication in a newspaper of general circulation where the missing party was last known to live. For certain probate publications, California Government Code 6061 requires publication one time.⁷ Before approving publication, the court will expect a declaration detailing every step you took to find the person. A vague statement that you “tried to find” someone will not do.

Waivers of Notice

A person entitled to notice can voluntarily waive it, and the court will accept a valid waiver in place of proof of service. Probate Code 1260 provides that if a party has waived notice, the court shall note the waiver in its order, and that finding becomes conclusive once the order is final.⁸

To hold up, a waiver must be knowing and voluntary. The person signing should understand which proceedings they are waiving notice of and what rights they are giving up, including the right to appear and object. A signed, written waiver that identifies the specific hearing is the safest form. If the court later finds that a waiver was not truly voluntary, it can set aside any resulting orders.

Proof of Service

After notice goes out, the server must complete and file proof of service with the court. Under Probate Code 1260, proof must be made to the court’s satisfaction at or before the hearing.⁸ If proof is missing or incomplete when the judge reviews the file, the hearing will almost certainly be continued.

The forms depend on how notice was delivered:

For service by mail, the proof is completed on the reverse side of the Notice of Hearing form (DE-120). If you served more than a handful of people, attachment form DE-120(MA) provides additional space.
For personal delivery, use Judicial Council Form DE-120(P), designed specifically for personal service of a notice of hearing in a decedent’s estate or trust matter.⁹
For service by publication, file a declaration describing the search for the missing party, together with an affidavit from the newspaper confirming publication dates.

Check that every person listed on Attachment 8 of the Petition for Probate also appears on the proof of service. Courts compare the two lists, and a name on one but not the other will trigger questions.

What Happens If Notice Is Defective

Before any hearing, judges confirm that notice went to every required party, that an approved delivery method was used, and that the 15-day timeline was met. If any piece is missing, the court will typically continue the hearing and order the petitioner to correct the problem and re-serve. That adds weeks to the probate timeline and generates additional filing fees and attorney costs.

If a party later claims they never received proper notice, the stakes rise. The court can invalidate prior orders if it finds that due process was not satisfied, and the petitioner carries the burden of proving compliance. Keep mailing receipts, copies of everything served, and file proof of service promptly.

More serious consequences follow when the omission appears intentional. Probate Code 8007 addresses situations where an interested party was knowingly left off the notice list. If an heir or beneficiary loses the chance to contest a will or object to a petition because they were deliberately excluded, the responsible party can face personal liability for the resulting harm.¹⁰ Courts can also remove a personal representative, impose monetary sanctions, or in extreme cases involving fraud, refer the matter for criminal investigation.

The court may dispense with notice entirely for good cause under Probate Code 1220(c), but that is a narrow exception for unusual circumstances, not a fallback for petitioners who did not plan ahead.⁴
