How Paternity Is Established in Utah
Utah law provides three distinct paths to establishing paternity. Which one applies depends on whether both parents agree, whether a government child support agency is involved, and whether custody and parent-time also need to be resolved.
Voluntary Declaration of Paternity
When unmarried parents agree, they can sign a Voluntary Declaration of Paternity by Parents, a legally binding form administered by the Utah Department of Health and Human Services, Office of Vital Records and Statistics. It’s typically signed at the hospital but may be filed at any time after the child’s birth. A properly signed and filed declaration carries the same legal weight as a court order, and the father’s name is added to the birth certificate.
Either parent has up to 60 days (or until a child support order is established, whichever comes first) to rescind a signed declaration. After that window closes, it can be challenged only on grounds of fraud, duress, or material mistake of fact.
Administrative Process Through ORS
The Utah Office of Recovery Services can establish paternity through an administrative process without court involvement, typically when child support is already in question. This route is faster in straightforward situations, but it has a significant limitation: an ORS administrative order can’t address custody or parent-time. If those issues need resolution, a court action is necessary.
Judicial Parentage Action
When paternity is disputed, when one parent refuses to sign voluntarily, or when custody and parent-time must also be resolved, a parentage action under the Utah Uniform Parentage Act is filed in district court. The court can order DNA genetic testing and issue temporary orders for custody, parent-time, and child support while the case is pending. A court order establishing paternity can be changed only by a later court order; a post-order genetic test can’t by itself undo an adjudicated determination.
After Paternity Is Established: What Comes Next
A judicial paternity order doesn’t end the legal process. It opens the door to downstream matters that often require their own attention.
Parenting Plans and Parent-Time Schedules
Final orders following a paternity case address legal fatherhood, custody arrangements, a parent-time schedule, child support, and decision-making authority. A well-drafted parenting plan covers holiday rotation, make-up time when a child is ill, communication between households, and transportation. Leaving these details undefined is a common reason families return to court.
Child Support Calculation
Utah child support is calculated under state guidelines using both parents’ incomes, the custody arrangement, and other relevant factors. Judges retain discretion when income is unusually high or a child has special needs that affect support costs.
Relocation and Modification
Once custody and support orders are in place, either parent may seek modification if there is a material change in circumstances. A custodial parent who wishes to move 150 miles or more from the other parent must provide advance written notice, and either parent can ask the court to weigh in on the disagreement. A judge may modify the parent-time schedule or custody arrangement if the proposed move wouldn’t serve the child’s best interests.
