Establishing Paternity in Utah

Short answer: Unmarried parents in Utah can establish legal paternity either by signing a Voluntary Declaration of Paternity (VDP) — the fastest and least expensive route — or through genetic testing, often arranged through the Office of Recovery Services (ORS), if there's any uncertainty. Only sign the VDP if you're confident about paternity, since it's a legal document with real consequences.

Who this guide is for

Unmarried parents in Utah — or anyone helping establish a child's legal father — trying to understand the available process.

Why establishing paternity matters

Legal paternity affects child support, custody and parent-time rights, inheritance, and access to benefits like health insurance and Social Security through the parent. Without it being legally established, an unmarried father generally has no automatic legal rights or obligations regarding the child, regardless of the biological relationship.

Option 1: Voluntary Declaration of Paternity (VDP)

This is a signed legal document where both parents acknowledge paternity — commonly completed at the hospital or birthing facility shortly after birth, though it can be done later too. It's described as the fastest, easiest, and least expensive way to establish paternity for unmarried parents in Utah.

Important: the VDP needs to actually be filed with the Utah Department of Health and Human Services, Office of Vital Records and Statistics — hospitals and birthing facilities usually handle this, but if it wasn't done at birth, confirm it gets properly filed.

Do not sign a VDP if you have any doubt about paternity. It's a legal acknowledgment with real consequences, and genetic testing is the appropriate path if there's uncertainty rather than signing and hoping it works out.

Option 2: Genetic testing through the Office of Recovery Services

If there's an open child support case with ORS, genetic testing can generally be requested — and is often provided at no charge before paternity and child support are formally established. This is the appropriate path when there's genuine uncertainty about paternity, rather than relying on the voluntary declaration.

Administrative vs. court-based establishment

Utah's Office of Recovery Services has authority to establish paternity through an administrative process that doesn't involve the court system — these administrative orders carry the same legal effect as a court order for paternity and child support purposes, but cannot address custody or parent-time. If custody or parent-time needs to be resolved (not just paternity and support), that generally requires going through the court system separately.

What happens after paternity is established

Once paternity is legally established — whether through the VDP or genetic testing — child support, and eventually custody and parent-time if needed, can be addressed. See Utah Child Support: How It's Calculated for that next step.

Frequently asked questions

Can paternity be established without genetic testing if both parents agree? Yes — the Voluntary Declaration of Paternity is exactly this option, for situations without dispute or uncertainty.

Is there a deadline to establish paternity? Establishing paternity generally isn't subject to the same kind of strict filing deadlines as some other family law matters, but resolving it sooner rather than later avoids complications with support, benefits, and custody down the line.

Can a signed Voluntary Declaration of Paternity be undone later? There are limited circumstances and timeframes for rescinding or challenging a signed VDP — this is exactly why it shouldn't be signed if there's genuine doubt in the first place, and why genetic testing is the safer path when uncertainty exists.
