Custody and parent-time
Utah separates legal custody (major decisions) from physical custody. Also, it sets parent-time schedules by statute. "Full custody" often means sole legal and sole physical custody.
Name what you need. Sole decision-making and primary residence need different proof.
The joint-legal presumption
There is a rebuttable presumption that joint legal custody serves the child, except where there is evidence of domestic violence, neglect, or physical, sexual or emotional abuse.
So shared decision-making is the starting point. A parent seeking sole legal custody is asking to overcome a presumption.
Statutory schedules, including equal time
Utah publishes a minimum parent-time schedule and an optional expanded one, and a court may order an equal parent-time schedule where it serves the child, each parent has been actively involved, and each can make it work.
That gives you concrete templates to build from rather than starting blank.
The best-interest factors
Section 81-9-204 weighs each parent's conduct and moral character, the child's bond with each parent, past care, and each parent's ability to cooperate and support the child's bond with the other, among others.
The court weighs that kind of evidence, not a parent’s sex.
Building the record
Document the care you give and log parent-time, exchanges and missed time with dates. Keep the messages behind each change.
Casewell keeps those entries and files together. So an Utah lawyer can review a clean record against section 81-9-204.
What counts as joint physical custody
Utah measures physical custody in overnights. Under section 81-9-101, joint physical custody means the child stays overnight with each parent for more than 30% of the year. Both parents also contribute to the child's expenses on top of child support.
More than 30% is roughly 111 nights, which is why you will hear lawyers talk about a 111-night line. The label matters because it feeds into how child support is worked out.
So count the nights you actually have, not the nights the order describes. A dated log of overnights is the only way to know which side of the line you are on.
The child's voice at 14
Utah gives a teenager's view extra weight without handing over the decision. Under section 81-9-204 the desires of a child aged 14 or older carry added weight. They are never the single controlling factor.
Below 14 a child's preference can still be considered, weighed against how well the child understands what is being asked.
No child in Utah picks their own arrangement. What a mature child can do is shift the balance where the rest of the evidence is close.
Before you file in Utah
Save any current order, track parent-time for a few weeks, and draft your proposed schedule measured against the statutory templates.
An Utah family-law lawyer can weigh it against the current statute and your district's practice before filing.

Document the facts that matter
Record what was planned, what happened, the child-related effect and the source in Casewell. That structure can save time and cost, make a pattern easier to assess and give an expert a clearer basis for presenting the case. Start your Casewell record today.
Does a 14-year-old choose which parent to live with in Utah?
No. Section 81-9-204 gives added weight to the desires of a child aged 14 or older. The judge still decides, and a child's wish is never the single controlling factor.
What counts as joint physical custody in Utah?
Overnights. Section 81-9-101 sets it at the child staying with each parent overnight for more than 30% of the year. That is roughly 111 nights. Both parents also contribute to the child's expenses.
Does Utah publish a full-custody success rate?
No. Public data does not give a complete percentage of Utah cases in which mothers or fathers receive sole legal and physical custody. Household statistics describe where children live, not court outcomes.
Do these statistics show that mothers get custody more often in Utah?
They show the sex of the household householder in a living-arrangement table. They do not show legal custody, parenting-time percentages, the reason for the arrangement, or whether a court was involved.
Can documentation improve my chances of custody?
Yes. Good records can definitely improve your chances. They help you arrive prepared with clear, dated evidence in the right format. They give your lawyer a head start, saving time and fees. They cannot guarantee an outcome, but they can strengthen your case.
What should I record first?
Start with the current arrangement, then record each material change with the date, what was expected, what you observed, the source, the child-related effect, your response, and the outcome. Use Casewell to keep the entry and supporting file together.
