Every year, thousands of estates enter probate without a valid will. When that happens, a body of law called intestate succession takes over-dictating exactly who inherits the deceased's property. The challenge? The rightful heirs are not always easy to find. They may live across the country, have lost contact with the family decades ago, or may not even know they stand to inherit. This guide explains how intestate succession works, why locating unknown heirs is harder than most people expect, and what practical steps attorneys, administrators, and families can take to ensure the right people receive what they are owed.
What Is Intestate Succession?
Intestate succession is the legal process that determines how a deceased person's estate is distributed when they die without a valid will. Each state has its own intestate succession statutes that create a priority hierarchy-typically beginning with a spouse and children, then extending to more distant relatives if no closer heirs survive.
When a person dies intestate, courts do not honor verbal wishes or informal agreements about who should receive property. Instead, state law steps in with a predetermined sequence of potential heirs.
That sequence typically follows this order:
- Surviving spouse
- Children and descendants (including legally adopted children)
- Parents
- Siblings and their descendants
- Grandparents and their descendants
- More distant relatives (aunts, uncles, cousins)
If no living relatives can be identified, the estate "escheats"-reverting to the state government. This outcome is almost always avoidable, but it requires a timely and thorough search effort.
One important distinction: intestate succession applies only to probate property-assets solely in the deceased's name that are not transferred by contract, beneficiary designation, or joint ownership. Life insurance policies, retirement accounts with named beneficiaries, and jointly held real estate typically pass outside of probate regardless of whether a will exists.
How State Laws Shape Intestate Heir Hierarchies
Each U.S. state has its own intestate succession statute that dictates which relatives inherit and in what share. While most states follow a broadly similar priority hierarchy, meaningful differences exist around spousal rights, half-siblings, stepchildren, and the representation of deceased heirs.
Spousal Share Variations
Some states grant a surviving spouse 100% of the estate when the deceased left no children. Others require the estate to be divided between the spouse and the deceased's parents. Community property states-Arizona, California, Nevada, Texas, and several others-treat assets acquired during marriage differently from separate property, which can significantly alter distribution.
Children Born Outside of Marriage
Most states today grant full inheritance rights to biological children regardless of the parents' marital status, provided paternity is legally established. Some jurisdictions also recognize equitable adoption for children raised as part of a family but never formally adopted through court proceedings.
Half-Siblings and Stepchildren
Half-siblings (those sharing one biological parent) are generally treated the same as full siblings in most states. Stepchildren, however, typically do not inherit intestate unless they were legally adopted.
Per Stirpes vs. Per Capita Distribution
When a direct heir predeceases the decedent, their share may pass to their own children under a "per stirpes" (by the branch) rule. Some states alternatively apply "per capita" distribution, dividing the estate equally among all surviving members of the same generation. These distinctions matter enormously when estate values are significant or when a family has grown in unexpected directions over decades.
Why Unknown Heirs Are So Common in Intestate Estates
Unknown heirs arise in intestate estates when branches of a family have lost contact, when the deceased had children from multiple relationships, or when records of biological relatives were never maintained. Family estrangements, adoptions, and long-distance moves all create gaps that formal records alone cannot reliably bridge.
Common reasons heirs go undiscovered include:
- Long-term estrangement: A sibling or child who lost contact 20 or 30 years ago may still hold full legal standing to inherit.
- Children from prior relationships: Decedents who had children from earlier marriages or relationships may not have disclosed them to their current family.
- Informal adoptions: Children raised by extended family members without formal legal proceedings often have uncertain inheritance status.
- Immigration and name changes: Relatives who immigrated or legally changed their names can be difficult to trace through standard vital records searches.
- Death of an intermediate heir: When the most direct heir-a child, for example-predeceased the decedent, the estate flows down to that person's own children, who may never have been in contact with the estate at all.
Personal representatives and estate attorneys carry a legal obligation to make a good-faith effort to notify all reasonably ascertainable heirs. Falling short of this standard can expose the estate to future claims, litigation, and in some jurisdictions, personal liability for the administrator.
Practical Methods for Finding Unknown Heirs
Finding unknown heirs requires a combination of vital records research, public record databases, social investigation, and in complex cases, professional forensic genealogy. No single source is sufficient-a thorough heir search draws from multiple independent records to build and verify a complete family tree.
Step 1: Collect Foundational Documents
Begin with the decedent's birth certificate, marriage records, divorce decrees, military discharge papers (DD-214), naturalization records, and any prior wills or trust documents. These anchor the research and immediately reveal which family branches require further investigation.
Step 2: Search Vital Records and Public Databases
Birth, death, and marriage records-available through state vital records offices and major genealogy platforms-establish family relationships across generations. The Social Security Death Index, historical census records, and obituary archives are also standard starting points in any estate heir search.
Step 3: Check State Unclaimed Property Databases
Many heirs are already reflected in state unclaimed property records. If a relative received a check that went uncashed, or held a dormant bank account, their name and last known address may appear in the state's database. Searching MissingMoney.com, which aggregates data from most states, is a routine step in professional heir search work.
Step 4: Conduct Skip Tracing
Modern data aggregation tools compile address histories, phone records, and public social profiles. Skip tracing-the professional practice of locating individuals through cross-referenced data sources-can surface current contact information for heirs who have relocated multiple times or changed their names.
Step 5: Engage Forensic Genealogy for Complex Cases
When paper trails go cold, forensic genealogy applies genetic genealogy techniques-including DNA database matching-alongside traditional document research to establish biological relationships. This is especially valuable in cases involving adoptees, unknown biological parents, or family lines with significant record gaps spanning multiple generations.
Our heir search services combine all of these methods into a documented, court-admissible process designed to satisfy the legal standard of a thorough and good-faith search.
What Happens to Dormant Assets When Heirs Are Not Found?
When no heirs are located within the statutory period, dormant assets held in the decedent's name-bank accounts, investment accounts, insurance proceeds, and real property-may be remitted to the state under escheat laws. Once escheated, assets can often still be claimed by rightful heirs, but the process becomes significantly more complex and time-consuming.
The Cost of Waiting
State escheat laws require financial institutions to report and remit dormant assets after a defined dormancy period-typically three to five years, though this varies by state and asset type. Once escheated, investment gains accrued during dormancy are rarely returned, and real property that escheats may be sold by the state before heirs are ever identified.
The Clock Starts at Death
From the moment of death, the dormancy period begins running on financial accounts. Estate settlement timelines and heir search timelines must run concurrently-not sequentially. Attorneys and personal representatives who wait to begin the heir search until other estate matters resolve risk allowing recoverable assets to slip into state hands.
Steps to Prevent Escheat During Active Probate
- File appropriate notices with financial institutions to suspend dormancy status during an active probate proceeding.
- Register the estate with state unclaimed property offices in every state where the decedent held accounts.
- Begin the heir search as early as possible-ideally within the first 60 days of estate administration.
Frequently Asked Questions
What is the difference between intestate and testate succession?
Testate succession occurs when a person dies with a valid will, and the will governs distribution of the estate. Intestate succession applies when there is no will-or when a will is declared invalid-and state law determines who inherits and in what share. The distinction affects not only who receives property but also who has authority to administer the estate and how quickly it can be settled.
How long does an heir search take in an intestate estate?
A basic heir search for a relatively straightforward family tree can often be completed in two to four weeks. Cases involving adoptions, unknown biological relatives, immigrants, or family lines spanning multiple generations may require two to three months or longer. Engaging a professional heir search firm early in the probate process significantly reduces delays in overall estate administration.
Can a long-lost relative inherit if they had no contact with the decedent?
Yes. Under intestate succession law, legal relationship-not personal relationship-determines inheritance rights. A sibling who had no contact with the decedent for 40 years carries the same legal standing as one who was in regular contact, provided the biological or legal relationship can be documented to the court's satisfaction.
What documentation is needed to prove heirship in probate?
Courts typically require certified copies of vital records-birth certificates, marriage certificates, and death certificates-establishing the chain of relationship between the decedent and the claimant. Where original records are unavailable, forensic genealogy research reports, DNA evidence, and sworn affidavits from knowledgeable witnesses may be accepted as supplemental proof of heirship.
Are there fees for recovering dormant assets from state unclaimed property funds?
Submitting a claim directly to a state unclaimed property fund is generally free of charge-states do not collect fees to process heir claims. However, professional heir search firms may charge contingency fees (a percentage of the recovered amount) for locating, documenting, and presenting an heir's entitlement. Contingency fee arrangements for heir location are regulated in a number of states, with caps that vary by jurisdiction.
