Responding to a Spouse's Petition to Modify Child Custody

Attorney Answer

A five-day deadline is unusual for a full response to a custody modification petition — before doing anything else, read the actual papers you were served to see whether that five days applies to a hearing date, a temporary-orders motion, or an order to show cause, rather than your answer to the petition itself.

Under Utah's general civil rules, a person served with a summons and complaint inside Utah normally has 21 days to file and serve an answer, and 30 days if served outside the state. A genuinely five-day deadline usually comes from something narrower — a scheduled hearing, a request for temporary orders, or a show-cause order — each with its own, much shorter timeline. Missing whichever deadline actually applies to you risks a default on the provisions your spouse is asking for, so this isn't something to guess about.

On the merits, Utah courts do not change custody just because one parent asks. The court may modify custody only if there has been a substantial and material change in circumstances since the existing order, and only if the change would be an improvement for the child and serve the child's best interest. Parent-time (visitation) changes have a lower bar — only a change in circumstances — so if the petition bundles both custody and parent-time provisions, they may not all be held to the same standard. If it asks to modify joint custody specifically, Utah law also requires a verified petition or affidavit and compliance with dispute-resolution steps before the court can act.

What you can do 1. Locate the actual summons, petition, or order you were served and identify exactly which document sets the five-day window and what it requires by then. 2. If a hearing or temporary-orders motion is set within five days, treat that as the priority — you may need to appear or respond in writing even before your full answer is due. 3. Contact Utah family law attorneys today and lead with the deadline, so the office can triage how fast you need to be seen. 4. If you cannot retain counsel before the deadline, consider filing a short response or objection yourself to avoid a default, then supplement it once you have a lawyer. 5. Keep a record of what has and has not been agreed to, since the substantial-and-material-change and best-interest findings will require evidence, not just your objection.

On timing: every deadline in a custody case is set by the specific document you were served, not by a general rule. Get the papers in front of a Utah family law attorney right away so the actual due date can be confirmed before it passes.
