Can an Illegitimate Child Claim Inheritance? When They Can & Can’t
If you were born outside marriage, you generally have the same inheritance rights as any other child under modern U.S. law.
Being born to unmarried parents does not, by itself, prevent you from inheriting from either parent.
Establishing your relationship with your mother is generally straightforward, but there can be a bit of a bump when inheriting from your father, as it may require additional proof of paternity.
- From the biological mother.
- From the biological father, if legal paternity is established.
- When the father dies without a will.
- When the father legally acknowledges parentage.
- When conceived before the father’s death but born afterward.
- When named as a beneficiary in a valid will.
- When biological paternity cannot be legally established.
- When adoption has legally severed inheritance rights from biological parents.
- When excluded by a valid will, subject to state-law exceptions.
- From relatives of the biological father without an independent legal basis.
- When applicable legal deadlines have expired.
Can an Adopted Child Inherit From a Biological Parent?
Adoption can change inheritance rights, but the outcome depends on state law, the type of adoption, and whether a will or trust applies. Find out when an adopted child may still inherit.
Federal Law and Inheritance Rights of Children Born Outside Marriage
By the way, there isn’t a single federal inheritance law that governs every child born outside marriage.
Instead, inheritance is primarily handled under state probate laws, with federal constitutional protections.
- The child can inherit from the mother’s estate.
- The child can claim an intestate share if the mother dies without a valid will.
- The child generally has equal inheritance rights alongside the mother’s other legally recognized children.
- A voluntary acknowledgment of paternity.
- A court order establishing parentage.
- DNA evidence, where permitted by state law.
- Other legally recognized evidence of the father-child relationship.
States cannot treat a child as having no legal relationship with a parent simply because the parents were not married.
There is also a federal connection through Social Security.
The Social Security Administration (SSA) recognizes certain nonmarital children for survivor benefits, including children who qualify as heirs under applicable state inheritance laws.
Can a Child Born Outside Marriage Inherit From Both Parents?
Yes, a child born outside marriage can inherit from both biological parents, regardless of whether the parents were married.
Every state allows a child born outside marriage to inherit from their mother, and all states provide a legal route for inheritance from the father when paternity is established.
Note: Requirements for proving fatherhood are not identical everywhere.
Some states make it relatively straightforward through a written acknowledgment or DNA test. Others have more specific requirements, particularly when the father has already died and the child is trying to establish inheritance rights through probate.

As you can see, the basic principle is similar across these states, but the evidence needed to establish the relationship is different.
For example, a child who has a signed acknowledgment of paternity may have a relatively straightforward claim in one state. Someone in another state may need to go through a probate hearing and provide additional evidence that the father recognized them as his child.
Can You Inherit From a Parent Who Dies Without a Will?
Yes, when someone dies without a valid will, their estate is distributed according to the state’s intestacy laws.
Under state intestacy laws, children generally have inheritance rights, whether their parents were married or unmarried.
Once the parent-child relationship is legally established, the child has the same inheritance rights as the parent’s other children.
| Situation | Who inherits? | Child’s inheritance |
|---|---|---|
| No will and no surviving spouse | All eligible children | Entire estate is generally divided equally |
| No will and a surviving spouse | Spouse and children | Children receive the share allocated under state law |
| Three children, including one born outside marriage | All three legally recognized children | Generally equal shares |
| A child dies before the parent, leaving children | Surviving children and grandchildren of the deceased child | Grandchildren may inherit their parent’s share |
| A child is legally adopted | Adopted child | Generally the same rights as a biological child |
| Legal parentage has not been established | Depends on applicable law | Legal proof of parentage may be required |
How Do You Prove Paternity When the Father Dies Without a Will?
Umm… this is often the most complicated part of the process.
If the father died without previously acknowledging the child or establishing legal paternity, the child may need to ask the probate court to recognize the relationship before receiving an inheritance.
Typically, this involves opening an intestate probate proceeding and filing a petition to determine the legal heirs. The child must then provide evidence showing that the deceased was their father.
Depending on state law, acceptable evidence may include:
- A voluntary acknowledgment of paternity signed by the father.
- A birth certificate identifying the father.
- A previous court order establishing paternity.
- DNA testing showing a sufficiently high probability of paternity.
- Letters, photographs, financial support records, or other documents showing that the father acknowledged the child.
- Testimony or affidavits from relatives, friends, or other people familiar with the relationship.
Most states will require clear and convincing evidence, particularly when the alleged father is no longer alive.
Here are a few examples.
| State | How Can Paternity Be Established? | Note |
|---|---|---|
| California | Through a court order or clear and convincing evidence that the father openly treated the child as his own. | Private acknowledgment alone may not be enough. |
| Georgia | Through a court order, signed acknowledgment, birth certificate, other qualifying evidence, or qualifying DNA testing. | DNA results showing at least 97% probability of paternity create a rebuttable presumption. |
| Alabama | Through a court decision or clear and convincing evidence. | The father must also have openly treated the child as his own and not refused support. |
How to Claim an Inheritance Without a Will
If you believe you are entitled to inherit from a parent who died without a will, here are the general steps involved that you need to follow:
-
Step 1
Open or locate the probate case
If probate has not started, an interested person may need to petition the court for administration of the estate. If a case is already open, obtain the relevant probate information and identify the executor or administrator.
-
Step 2
Identify the estate assets
Find out what property, bank accounts, investments, and real estate are included in the estate. This helps establish what may eventually be distributed to the heirs.
-
Step 3
Notify the court or administrator
If you are not listed as an heir, notify the probate court and the estate’s administrator or executor that you believe you have an inheritance claim.
-
Step 4
Gather evidence of parentage
Collect your birth certificate, paternity acknowledgment forms, letters, family photographs, school or medical records, and any other documents showing the relationship. DNA testing may also be necessary.
-
Step 5
File a petition to determine heirship
Depending on the state, you may need to file a petition asking the probate court to recognize you as the deceased parent’s child and include you among the legal heirs.
-
Step 6
Attend the hearing
If paternity is disputed, the court may schedule a hearing where you can present documents, DNA results, and witness testimony.
-
Step 7
Obtain the court’s decision
If the court accepts the evidence, it can recognize you as an heir. You can then receive the share of the estate provided under the state’s intestacy laws, subject to other heirs’ and surviving spouses’ rights.
The process can take time, particularly if other family members dispute the claim or the estate has already been distributed. This is one reason why it is generally better to notify the probate court as soon as possible.
What Happens If the Parent Leaves a Will?
If a parent leaves a valid will, the estate is generally distributed according to the instructions in the will.
A child born outside marriage can inherit if named as a beneficiary.
| No. | Situation | What Does the Law Say? | Inheritance Outcome |
|---|---|---|---|
| 1 | Child named in the will | The parent expressly includes the child as a beneficiary. | The child can inherit according to the will, just like the other children. |
| 2 | Child accidentally left out | Pretermitted-child laws may protect children unintentionally omitted from a will. | The child may receive a share of the estate under applicable inheritance laws. |
| 3 | Child intentionally disinherited | A parent may generally exclude an adult child from a will, subject to applicable legal protections. | The child generally receives no inheritance unless there are valid grounds to challenge the will. |
| 4 | Surviving spouse has legal rights | The surviving spouse may be entitled to a share under community property or elective-share laws. | The spouse’s share may reduce the property available for distribution among the children. |
How to Prove You Are a Parent’s Child for Inheritance Purposes
As we’ve discussed, establishing parentage is often the most important part of an inheritance claim, particularly when the father has died.
Fortunately, there are several types of evidence that probate courts may accept. The exact requirements depend on state law, but the following are among the most common.
- Birth Certificate: A birth certificate listing the deceased as a parent can be useful evidence.
- Voluntary Acknowledgment of Paternity: Many states allow an unmarried father to sign a voluntary acknowledgment of paternity, often at the hospital or through the state’s vital records office.
- Paternity Affidavits and Forms: Some states have additional forms or registries that allow unmarried fathers to formally acknowledge a child.
- Court Order: A previous family court judgment establishing paternity can be particularly useful.
- DNA Testing: DNA testing is another common way to establish biological parentage.
So, being born outside marriage does not mean you lose the right to inherit from your parents. Children generally have the same inheritance rights regardless of their parents’ marital status, provided the legal parent-child relationship is established.
