If you’re trying to transfer property or close an estate in Utah without going through probate, you might be considering an heirship affidavit. But before you draft or file one, you need to know whether you’re legally allowed to do so. The eligibility criteria for filing heirship affidavit in Utah aren’t optional they’re built into state law. Get this wrong, and the affidavit may be rejected, delay title transfers, or even expose you to liability.

Who qualifies to file an heirship affidavit in Utah?

In Utah, only certain people can sign and file an affidavit of heirship. You must be an heir of the deceased person meaning you’re related by blood, adoption, or marriage and you must have personal knowledge of the family facts stated in the affidavit (like who the heirs are, whether the decedent had a will, and whether there are any surviving spouses or minor children). You also can’t be the sole heir if there are other known heirs; the affidavit must list all known heirs, not just yourself.

For example, if your uncle died without a will and left behind two siblings (your parent and an aunt), both siblings or their descendants, if they’ve passed would need to be accounted for. You wouldn’t qualify to file alone just because you’re the one handling paperwork. That’s why many families turn to a trusted relative who meets all eligibility requirements.

What counts as “personal knowledge” and what doesn’t?

Utah law requires the affiant (the person signing) to swear under oath that they personally know the facts about the decedent’s family relationships and estate. This means you were present for key life events like marriages, births, adoptions, or deaths or you’ve reviewed official documents (birth certificates, marriage licenses, death certificates) yourself. It does not mean you heard something from a cousin at a reunion or read it in an old letter.

A common mistake is asking a friend or neighbor to sign because they “know the family.” Unless that person actually witnessed or documented the relationships, their affidavit won’t hold up. Courts and title companies often reject affidavits signed by people without direct, firsthand knowledge. If you’re unsure whether your knowledge qualifies, review the filing requirements for relatives to see how Utah defines acceptable knowledge.

Can a spouse, child, or sibling always file?

Not automatically. Being a close relative helps, but it’s not enough on its own. You still need personal knowledge of the full heirship picture. For instance, a surviving spouse can file but only if they know whether the decedent had children from another relationship, whether any heirs are minors, and whether there’s a valid will somewhere. A child might know their own parentage but not know about a half-sibling born before their parents married. In that case, they’d need to include that sibling in the affidavit or find someone who can verify that relationship.

This is why some families use more than one affiant, especially when heirs live in different states or have incomplete information. You’ll find more detail about who’s authorized in the list of authorized filers.

What happens if someone files who isn’t eligible?

An ineligible filing doesn’t just get ignored it can cause real problems. A title company may refuse to insure the property transfer. A county recorder may reject the document outright. Worse, if false statements are made (even unintentionally), the signer could face perjury charges. Utah Code § 75-3-901 outlines penalties for knowingly false affidavits, including fines and possible jail time.

That’s why it’s worth double-checking eligibility before signing. If you’re uncertain whether you meet the criteria, it’s safer to consult with someone who does or to look into alternatives like small estate affidavits or informal probate. More details about the full process are available in the step-by-step legal process.

Practical next step

Before drafting anything:

  • Confirm you’re an heir under Utah law (see how Utah defines heirship)
  • Make a list of all known heirs including those who’ve predeceased the decedent (and their descendants)
  • Gather copies of birth, marriage, and death certificates you’ll rely on
  • Ask yourself: “Can I swear under penalty of perjury that I personally know each fact I’m stating?” If not, find someone who can.

Utah’s heirship affidavit is a useful tool, but only when used correctly. When in doubt, talk to a Utah attorney familiar with estate administration. You can also review the official guidance from the Utah State Courts Probate Forms page.
