If you have been appointed personal representative, here is how to notify heirs, beneficiaries, and creditors in probate: within 30 days of receiving your letters of authority, send written notice by certified mail to every heir at law, every person or entity named in the will, and every creditor you can identify from the decedent’s records; publish a notice to unknown creditors in a local newspaper; and file proof of every notice with the probate court. Miss any of those steps and you can be personally liable, removed as personal representative, or forced to reopen a closed estate.
Who You Have to Notify
Three groups are entitled to notice in almost every probate case, and identifying each one correctly is your first job.
Heirs at law are the people who would inherit under your state’s default rules if there were no will — usually the surviving spouse and children first, then parents, siblings, and more distant relatives.1Legal Information Institute. Heir at Law They get notice even when there is a valid will, because they have standing to challenge it. A disinherited child who never learns probate was opened can surface later and unwind what you have done.
Beneficiaries are the people and organizations named in the will itself, whether or not they are related to the decedent. A friend, a charity, or a business partner all qualify. They receive notice so they know about the potential inheritance and can object if they believe the estate is being mismanaged.
Creditors split into three groups that get different treatment:
- Known creditors — identifiable from the decedent’s records (mortgage lenders, credit card companies, medical providers, tax authorities). These get direct notice by mail.
- Reasonably ascertainable creditors — ones you should be able to find through a careful review of mail, bank statements, and financial files. These also get direct notice.
- Truly unknown creditors — only these can be notified by newspaper publication alone.
The distinction matters because publication does not satisfy due process for creditors whose identities you knew or should have known. The Supreme Court held that if a creditor is known or reasonably ascertainable, the personal representative must send actual notice by mail or another method certain to reach them.2Legal Information Institute. Tulsa Professional Collection Services Inc. v. Pope The broader constitutional rule is that notice must be “reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections.”3Legal Information Institute. Mullane v. Central Hanover Bank and Trust Co. Gesture notice does not count.
When a Recipient Is a Minor or Incapacitated
If an heir or beneficiary is a minor or a legally incapacitated adult, they cannot receive and act on notice themselves. The court appoints a guardian ad litem — an independent advocate whose only job is protecting that person’s interests — who reviews the proceedings, files responses on their behalf, and is paid a reasonable fee out of estate assets. If the person already has a legal guardian, that guardian can often acknowledge service, but the court can still appoint a separate guardian ad litem if the existing guardian has a conflict.
Your Deadlines
Two clocks start at your appointment and run in parallel.
Heirs and Beneficiaries: 30 Days
Under the Uniform Probate Code, which about half of states have adopted in some form, you must inform all heirs and devisees of the appointment within 30 days of receiving your letters. Many non-UPC states use a similar window. The notice has to include your name and address, the court handling the case, and the date of appointment or will admission. That 30-day period also opens the window for interested parties to object to your appointment or contest the will. Miss it and the court can remove you for breaching your fiduciary duty.
Creditors: The Nonclaim Period
For creditors, the clock is set by when you publish and mail. Publication in a local newspaper starts a fixed period during which creditors must file claims or lose them. The UPC sets this nonclaim period at four months from first publication; states that have modified the UPC or written their own codes run from two to six months. For known creditors receiving mailed notice, the clock typically starts on the mailing date rather than the publication date.
Publishing early is one of your most important first moves. Delaying publication delays the start of the nonclaim period, which delays closing the estate. Experienced probate attorneys treat publication as one of the first acts after appointment for that reason.
Information and Forms to Gather First
Errors in your notice paperwork stall everything, so get the details right before you mail anything.
You need the full legal name and current mailing address of every heir, beneficiary, and known creditor. The decedent’s Social Security number helps creditors match internal records. Every notice document should include the probate case number, the date of death, the name and location of the court, and contact information for the estate’s attorney if you have retained one.
Most probate courts publish standardized forms — sometimes called a Notice of Administration or Notice to Creditors — on their websites or at the clerk’s office. Use the court’s own form when one exists; it covers every required field.
Two Federal Filings You Should Not Skip
File IRS Form 56 to formally notify the IRS that you are acting as the fiduciary for the estate. This establishes your authority to handle the estate’s tax matters and to receive correspondence that would otherwise go to the decedent.4Internal Revenue Service. Instructions for Form 56 File it as soon as you are appointed.
Then apply for an Employer Identification Number for the estate. The IRS treats the estate as a separate taxpayer, and you must file an estate income tax return if the estate’s assets generate more than $600 in annual income.5Internal Revenue Service. Responsibilities of an Estate Administrator Applying online through IRS.gov is free.6Internal Revenue Service. Information for Executors Including the EIN on notices to creditors and financial institutions helps them process the estate through their compliance systems.
How to Deliver Each Type of Notice
Match the method to the recipient. Get it wrong and the notice may be invalid, which means the nonclaim clock never starts.
Certified Mail for Known Parties
Certified mail with return receipt requested is the standard method for heirs, beneficiaries, and known creditors. The signed green card (or its electronic equivalent) is your proof of receipt. As of 2026, one certified letter with a physical return receipt runs about $10 at the post office, so budget that cost across every recipient. For a large estate with dozens of creditors it adds up quickly. Some jurisdictions also allow personal service by a licensed process server, which provides stronger proof but typically costs $20 to $150 per service.
Publication for Unknown Creditors
For creditors you truly cannot identify after reasonable diligence, publish in a newspaper of general circulation in the county where the decedent lived. Depending on the state, the notice usually runs once a week for two or three consecutive weeks. Costs generally run $100 to $500. The probate clerk’s office can usually point you to publications that meet the “general circulation” standard.
Heirs Living Abroad
Service outside the United States is more complicated. If the heir lives in a country that has signed the Hague Service Convention and objected to service by postal channels, you generally cannot rely on certified mail. The U.S. Department of State lists several alternatives, including service through the foreign country’s designated central authority, retaining a foreign attorney or process server where local law allows, or requesting assistance through letters rogatory.7U.S. Department of State. Service of Process Letters rogatory involve a formal request from the U.S. court to a foreign court and can take a year or more. Budget extra time and legal fees, and consult an attorney who handles cross-border matters.
When You Cannot Find an Heir
Before you can rely on publication for a missing heir, you have to show the court you made a genuine effort to locate them. This “due diligence” standard is stricter than many personal representatives expect.
Steps that typically satisfy a diligent search include contacting known relatives and friends, checking last known addresses, searching property records, reaching out to past employers, and searching online, including social media. If those come up empty, you can ask the court for permission to spend estate funds on a professional heir-search firm or genealogist. These firms specialize in establishing kinship and producing court-ready documentation.
After the search, file a sworn statement detailing every step and why you could not locate the person. Judges have broad discretion to decide whether your efforts were enough. If the court finds your search was halfhearted, it can order you to do more before permitting publication. Document as you go — a log of every phone call, returned letter, and dead end becomes the backbone of that sworn statement.
Filing Proof of Service With the Court
Sending notice is not the end of the task. You have to prove to the court that you sent it. That proof takes the form of a Proof of Service or Affidavit of Mailing filed with the probate clerk. It lists each person notified, the date, the method of delivery, and for certified mail the tracking number or a copy of the signed green card.
These affidavits are a prerequisite to closing the estate. A judge will not sign a final distribution order or discharge you as personal representative without them. The affidavit typically needs to be notarized, which runs $5 to $10 in most states (a handful of states set no maximum or charge nothing). Keep copies of every return receipt and every publication affidavit from the newspaper, because the court may ask for the attachments.
Government Agencies That Also Need Notice
Beyond private heirs, beneficiaries, and creditors, two agencies routinely need to hear from the personal representative.
Social Security Administration
In most cases the funeral home reports the death to the SSA. If no funeral home was involved, or the death was not reported, call the SSA at 1-800-772-1213 with the decedent’s name, Social Security number, date of birth, and date of death.8Social Security Administration. What to Do When Someone Dies Any benefits paid after the date of death must be returned, so reporting promptly prevents overpayments that complicate administration later.
State Medicaid Agency
Federal law requires every state to seek recovery from the estates of certain Medicaid recipients, particularly those who were 55 or older when they received benefits or who received nursing facility services.9Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Many states require the personal representative to notify the state Medicaid agency directly, often by certified mail, within a set period after appointment. The notice typically includes the decedent’s identifying information, the court and case number, and the date letters were issued. Check your state’s rules early: some states prohibit any distribution until the Medicaid agency has responded or a waiting period has passed.
What Happens If You Do Notice Wrong
The consequences of inadequate notice go well beyond delay.
If you fail to notify a known creditor, that creditor’s claim can survive the nonclaim period. Because the Constitution requires actual notice for known creditors, publication alone does not start the clock against them. A creditor who never received proper notice can petition the court to reopen the estate, potentially unwinding distributions that already went to beneficiaries.
Your personal exposure is the more serious risk. If your carelessness caused the estate to fail to pay a legitimate debt, you can be held personally liable for the amount that creditor should have received. The liability attaches not because the estate owed the money but because your failure to follow the notice rules prevented the orderly payment probate is designed to produce.
For heirs and beneficiaries, defective notice can invalidate the whole proceeding. An heir who never learned about the case can challenge the will admission or your appointment long after the normal objection period. Courts that find the personal representative failed to exercise reasonable diligence in providing notice can vacate prior orders, reopen the estate, and in serious cases remove and replace the personal representative. The simplest protection: treat notice as the single most important task in your first 30 days, and document every step thoroughly enough that no one can credibly say they were left in the dark.
