Proving Parentage for Inheritance in Utah

Short answer: If your father’s name is not on your birth certificate, you can still prove you are his child for inheritance in Utah by establishing legal parentage. This is typically done through a recorded voluntary acknowledgement of paternity, a court order establishing paternity (often supported by DNA testing), or other clear evidence recognized by the probate court. Acting quickly and gathering documentary and testimonial evidence will make the process easier. This is general information only and not legal advice.

How Utah law treats children and heirs

Under Utah’s probate rules, a decedent’s children (that is, their legally established biological or adopted children) are among the persons who may inherit when a person dies without a valid will. See Utah’s intestate succession rules for the statutory framework: Utah Code Section 75-2-102 (Intestate Heirs).

Main ways to prove parentage in Utah

  1. Voluntary Acknowledgment of Paternity (VAP)

    If your father signed a voluntary acknowledgment of paternity that was properly recorded with the vital records office, that document is strong proof of paternity. In many cases the VAP is as legally effective as a court order. Utah courts and the Utah Department of Health explain how acknowledgments work and where they are filed: Utah Courts: Paternity and Establishing Parentage.

  2. Court order establishing paternity

    If there is no VAP, you can ask a Utah court to declare that a deceased person was your father. This normally requires filing a paternity action (or a petition in the probate case) and asking for genetic testing if needed. A court may issue a judgment of parentage based on DNA results and other evidence. Once a court order is entered, the probate court will treat you as the decedent’s child for inheritance purposes.

  3. Posthumous DNA testing

    If the alleged father is deceased, DNA testing may still be possible using stored tissue, medical samples, or testing close biological relatives (siblings, parents, children of the decedent). A court can order testing of available samples or relatives to determine genetic relationship.

  4. Other admissible evidence

    If DNA is not available, courts consider documentary and testimonial evidence: affidavits saying the decedent publicly acknowledged you as his child, family photos, school or medical records listing parentage, financial support records, correspondence, and testimony from family members or community members who knew the relationship. This evidence can help support a court finding of parentage under Utah law.

Typical steps to take if you need to prove parentage for inheritance

  1. Open or review the probate file

    When someone dies, probate may be opened where assets are distributed. If a probate case is already open, file a written request with the probate court to be named as an heir or to appear as a claim of interest. If probate has not been opened, someone (often an executor, personal representative, or interested person) must start the probate process.

  2. Gather documents

    Collect your birth certificate, any signed acknowledgments, school or medical records, photos, letters, baptismal or church records, documents showing financial support, and contact information for witnesses who can attest the decedent recognized you as his child.

  3. Request DNA testing if needed

    Ask the probate court or the family court to order genetic testing. If the alleged father is deceased, the court can order testing of preserved samples or close relatives. DNA is the most persuasive evidence of biological parentage.

  4. File a petition to establish parentage

    If no voluntary acknowledgment exists, file a petition asking the court to establish parentage. This may be a separate paternity action or incorporated as an issue in the probate case. The petition should state facts, attach supporting documents, and request appropriate orders (testing, declaration of heirship, distribution of estate assets).

  5. Attend hearings and present witnesses

    Be prepared to present witnesses who knew the relationship, the results of any DNA tests, and your documentary evidence at hearing. The court will weigh the evidence and issue a ruling.

Burden of proof and timing

In civil proceedings such as probate and paternity cases, the standard is typically a preponderance of the evidence (more likely than not). DNA testing usually satisfies this standard easily. Because probate matters have deadlines (claims deadlines, distribution deadlines, statute of limitations for challenging a will), you should move promptly. If you wait too long, you may lose rights or face procedural bars.

Probate and parentage issues can be legally and emotionally complex—especially when the alleged parent is deceased. A Utah probate or family law attorney can help you evaluate evidence, file the correct petitions, request DNA testing, and represent you at hearings. If cost is a concern, contact local legal aid organizations or the Utah State Bar for referrals.
