If you’re handling a loved one’s estate in Utah and there’s no will or the will doesn’t cover all property you might need to file an affidavit of heirship. But before you print or sign anything, you need to know: who can submit the form. That’s not just paperwork it’s about legal standing. Only certain people are allowed to file this document, and if the wrong person does, the affidavit won’t hold up in court or with title companies.

Who qualifies to sign and submit an affidavit of heirship in Utah?

In Utah, the person who signs and submits the affidavit must be someone who knew the deceased well typically a family member or close friend and who can swear under oath about the decedent’s family relationships, marital history, and lack of a will. The signer doesn’t have to be an heir themselves, but they must have personal knowledge of the facts stated. Common filers include adult children, siblings, parents, or long-time neighbors who attended family events and knew the decedent’s living situation firsthand.

You’ll also need two disinterested witnesses people who aren’t heirs, beneficiaries, or related by blood or marriage to the decedent or the heirs. Their role is to verify the signer’s identity and confirm the affidavit was signed willingly. This requirement helps prevent fraud and supports the document’s credibility.

What happens if the wrong person files it?

If someone without personal knowledge signs the affidavit say, a distant cousin who never met the deceased the document could be rejected by a county recorder or challenged later during a title transfer. Worse, filing false statements knowingly is perjury, which carries legal penalties. We’ve seen cases where heirs tried to rush the process by asking a neighbor to “just sign it,” only to find out months later that the property couldn’t be sold because the affidavit lacked proper foundation.

It’s not enough for someone to be related they must be able to speak truthfully about things like whether the decedent was married at death, how many children they had, or whether any heirs predeceased them. That’s why checking eligibility matters more than speed.

Do heirs themselves need to sign the affidavit?

No only the affiant (the person making the sworn statement) signs it. Heirs don’t sign unless they’re also serving as the affiant. In fact, having heirs sign as witnesses would violate the “disinterested” rule. If you’re an heir wondering whether you can file, the answer depends on your relationship and knowledge not just your status.

Where do you file it and what comes next?

Once completed and notarized, the affidavit gets filed with the county recorder in the Utah county where the real property is located. It doesn’t go to probate court unless contested. Filing creates a public record that helps establish ownership when transferring land, refinancing, or selling. But remember: this isn’t a substitute for probate in all cases especially if there’s debt, disputes among heirs, or complex assets.

For example, if the deceased owned a home in Salt Lake County and a small rental in Cache County, you’d typically file the affidavit in Salt Lake County (where the primary residence was), but may need separate filings or additional steps for the second property. That’s why reviewing the filing requirements for relatives in Utah helps avoid delays.

Common mistakes to avoid

  • Using a notary instead of a witness: Notaries verify identity and willingness they don’t attest to facts. You still need two qualified witnesses.
  • Leaving blanks or guessing at family details: If you’re unsure whether the decedent had a prior marriage or a child born outside marriage, leave it out or consult an attorney. Guessing risks invalidating the whole affidavit.
  • Filing before gathering supporting documents: While not required, having copies of birth certificates, marriage licenses, or death certificates on hand makes the process smoother and strengthens credibility.

Utah law doesn’t require attorneys to file affidavits of heirship but if the family structure is unclear, there’s disagreement among heirs, or the estate includes significant assets, speaking with a local probate attorney is wise. The Utah State Bar offers a lawyer referral service here.

Before you file: Double-check that your affiant has direct knowledge of the decedent’s family and marital history, confirm your two witnesses meet the disinterested requirement, and make sure every fact stated can be verified by someone else.
