The goal is to help you act efficiently and lawfully so the probate process can move forward.

Detailed answer — locating a missing parent during probate in Delaware

When a parent is missing at the time you need to begin probate, your immediate priorities are (1) protect the estate, (2) make reasonable efforts to locate the missing parent (or other heirs), and (3) follow Delaware probate procedures for serving or notifying unknown or absent parties. Delaware’s decedent’s estate laws govern who may act for the estate and how notice is provided; you can review the Delaware Code governing decedents’ estates at the Delaware Code Title 12 page: https://delcode.delaware.gov/title12/. For procedural help and local filing information, see the Delaware Courts site: https://courts.delaware.gov.

Key points under Delaware practice (general guidance):

• Open the estate promptly. A personal representative (executor or administrator) or petitioner should file with the appropriate Delaware probate office (Register of Wills or the court handling probate matters) even if an heir is missing. Opening the estate starts the formal process and protects estate assets.
• Make reasonable, documented search efforts. Courts expect documented, reasonable efforts to locate missing heirs before permitting alternative notice (for example, publication). Reasonable efforts commonly include searching public records, contacting last known relatives and employers, checking Social Security records, and using online databases.
• Service by publication or appointed representative. If the parent’s location cannot be determined after reasonable searches, Delaware procedure generally allows the court or probate office to permit notice by publication or alternative service. The court may also appoint a guardian ad litem or an attorney to represent the missing person’s interests during probate. The exact procedure and paperwork are controlled by Delaware probate rules and the Register of Wills or court handling the estate.
• Bond and special appointments. If an heir or interested person cannot be found, the court may require a bond or special procedures to protect the estate while it is administered. The personal representative should confirm these requirements with the Register of Wills or the court to avoid personal liability.

Common search categories and where to look (practical steps):

1. Start with what you know. Collect the decedent’s documents — last will (if any), past mail, tax returns, bank records, medical records, vehicle registration, and any correspondence that might list a parent’s last known address or employer.
2. Contact close family and friends. Ask siblings, children, long-term friends, neighbors, old coworkers, and clergy if they know the parent’s whereabouts or last contact date.
3. Check government records. – Social Security Administration: request benefit or wage records (you may need the decedent’s SSN and proper authorization). – Delaware Vital Records and Delaware Public Archives for birth, marriage, or other filings: https://archives.delaware.gov.
4. Search public indexes and databases. Use property tax records, county assessor/recorder searches, voter registration, and court records in counties where the parent lived. Many counties provide online searchable databases.
5. Use address forwarding and phone checks. Contact the U.S. Postal Service for forwarding requests (National Change of Address) and check online phone directories and reverse-lookup services.
6. Check benefit and medical contacts. Contact hospitals, long-term care facilities, and the Department of Veterans Affairs (if applicable) to see if the missing parent had recent contact or claims.
7. Hire a professional search service. If initial steps fail, consider a licensed private investigator or a licensed attorney experienced in Delaware probate to perform a focused heir search, background checks, and official records requests.

What the probate office or court will expect you to show

• Documentation of where and how you searched (who you called, what records you checked, dates and outcomes).
• Copies of notices mailed to last-known addresses, and copies of phone calls or emails where applicable.
• If you request service by publication, a proposed publication plan and affidavit describing your search efforts.
• Any affidavits from witnesses who can testify to the parent’s history or disappearance.

If you cannot find the parent

If a parent remains missing after reasonable searches, the Register of Wills or the probate court can typically allow alternative notice (for example, notice by publication in a newspaper) and proceed with administration. The court often appoints a representative to protect the missing person’s share. Following Delaware’s procedures and showing good-faith, documented efforts reduces the risk of future challenges by a later-appearing heir.

Hypothetical example

Consider this hypothetical: You are the decedent’s adult child and need to open probate. The decedent named their own parent (your grandparent) as a beneficiary and next-of-kin, but that parent moved out of state and stopped responding five years ago. You file a probate petition in Delaware and document that you: called family members, checked the county property and voter rolls, contacted the Social Security Administration, and searched online databases. You file an affidavit summarizing these efforts and ask the Register of Wills for permission to publish notice. The Register approves publication and appoints a guardian ad litem for the missing parent. After the required notice period, the estate proceeds and the court protects the missing parent’s potential share. If the parent later appears, the court will evaluate any claim under the rules that governed the prior notices and distributions.

Helpful hints

• Document every step. Keep copies of emails, call logs, letters, and records you pull. Courts rely on documentation.
• Contact the Register of Wills early. Each Delaware county has procedures and clerks who can explain local filing and notice practices—contact them before you file paperwork.
• Use official government channels. For searches that require secure information (for example, full Social Security records), go through the SSA or other agencies rather than relying solely on commercial sites.
• Consider a limited-time search budget. Private investigators and genealogists can be effective for difficult cases; weigh the cost against the estate’s value and the likelihood the missing parent can be found.
• Be careful with privacy. Do not publish sensitive personal identifiers (Social Security numbers, full financial account numbers) in public notices or online postings.
• Get legal help when unsure. An attorney experienced in Delaware probate can help prepare sworn affidavits, file appropriate motions, and reduce your personal risk as personal representative.

Next steps and where to get help

1) Gather the decedent’s documents and list all lead contacts. 2) Contact the Register of Wills or probate clerk in the county where the decedent lived to learn local filing and notice rules (see Delaware Courts and the Delaware Code Title 12 index at https://delcode.delaware.gov/title12/). 3) If your searches fail, ask the clerk about publishing notice and any court forms used when a potential heir cannot be located.
