Five steps. You'll pick a Utah statutory parent-time schedule, see your actual overnight counts and which child-support worksheet they trigger, allocate holidays, and choose the ground rules that get written into the plan — in the same legal wording divvi puts in the documents you file. Nothing is saved and no account is needed.
It creates a printable outline covering the custody schedule, annual overnights, holidays, summer parent-time, exchanges, communication, and the ground rules you select. It is a planning tool until the terms are placed into court documents and signed.
On an equal-time schedule this barely matters — it only decides who is named first in the plan.
A Utah parenting plan sets out legal custody (who makes major decisions), physical custody and the parent-time schedule, the regular week, holidays, school breaks and summer, plus how you will exchange the children, how you will communicate, and how you will resolve disagreements later. Utah requires one in any divorce involving minor children. Most people start from a statutory schedule and then adjust it, because a schedule a court already recognises needs less explaining than one built from scratch.
Utah's statutory minimum for a child aged 5 to 18 is set by Utah Code § 81-9-302, alternating weekends, one weekday evening, and a division of holidays and summer. § 81-9-303 is the optional expanded schedule, which works out at 145 overnights a year and is treated as joint physical custody for child support. There is a separate minimum for children under five (§ 81-9-304) and an equal, 50/50 option (§ 81-9-305). Parents are free to agree to something different; the statutory schedules are the floor and the default, not a limit.
Two numbers do two different jobs. Utah defines joint physical custody as each parent having the child more than 30% of the year, which is 110 overnights (§ 81-9-101). But qualifying for the joint child-support worksheet takes at least 111, § 81-6-206(4)(a) credits the overnights over 110, so at exactly 110 the credit is zero and nothing changes until 111. If your schedule sits near that line, count the overnights before choosing a worksheet.
Utah's statutory schedules divide the holidays rather than splitting each one, with the parents alternating years on most of them, so neither parent misses the same holiday twice running. You can agree to any arrangement you both prefer, including keeping particular days with a particular parent every year, but writing it out beats leaving it to goodwill. A holiday clause that names the date, the pickup time and the handover place is the one that stops the argument three years from now.
Yes, but not by agreement alone once it is in a decree. Changing custody or parent-time takes a petition to modify under Utah Code § 81-9-208 and generally requires a substantial and material change in circumstances since the decree. Parents often work around small changes informally; the risk is that an informal arrangement is unenforceable the day one of you stops honouring it.
