In most family courts, you have between 14 and 30 days from the date you were served to file a written response to a motion. The exact number depends on your state’s rules of civil procedure, your county’s local rules, and the type of motion filed. That range is the answer to how long to respond to a motion in family court, but the deadline is one you cannot afford to guess at: if you miss it, the judge can grant the other party’s request without ever hearing your side.
When the Clock Starts
Your countdown begins the day you are officially served, not the day the motion was filed and not the day you happened to open the envelope. Look at the certificate of service attached to the papers. It states the date and method of service, and that date is your starting point.
Most courts count calendar days, including weekends and holidays. Under the federal model that most states follow, you skip the day of service itself, so if you were served on a Monday with a 14-day deadline, day one is Tuesday. If the final day lands on a Saturday, Sunday, or legal holiday, the deadline rolls to the end of the next regular business day.1Legal Information Institute.

How you were served can change the math. When service happens by mail, many courts add three extra days to the response period to account for delivery time.1Legal Information Institute.

Emergency and Ex Parte Motions
The standard window doesn’t apply when the other party files an emergency motion or requests ex parte relief. Family courts see these often in cases involving child safety, domestic violence protective orders, and urgent financial matters. A judge can issue temporary orders before you have any chance to respond.
When a court grants emergency orders, it typically schedules a follow-up hearing within a short period, often a few weeks, where you get your opportunity to present evidence and argue your position. Your written response in that situation may be due just days before the hearing rather than within the standard 14-to-30-day window. Some courts require it by a specific time on the morning of the hearing itself. If you receive notice of an emergency motion, call the court clerk that day and get the exact deadline in writing.
Asking for More Time
If the deadline is coming up fast and your response isn’t ready, the fastest path is to contact the other party or their attorney and ask for a stipulation. A stipulation is a written agreement between both sides extending the deadline to a specific new date. Once signed, you file it with the court for approval. Most judges will approve a reasonable stipulation, especially a first request, without much scrutiny.
If the other party refuses, you can file a motion asking the court for an extension. That motion must show “good cause.”1Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers Good cause means more than “I didn’t get around to it.” Legitimate reasons include needing time to hire an attorney, difficulty gathering financial records, complexity of the issues, or a personal emergency. The judge has full discretion.
There is no hard cap on how many extensions you can request, but each additional one is harder to justify. Judges view repeated requests as a sign the party isn’t taking the case seriously or is stalling, and eventually the court will deny the request and hold you to the existing deadline. File your extension request before the current deadline expires. Asking for more time after the deadline has already passed requires you to meet the higher standard of “excusable neglect,” which is significantly harder to establish.1Legal Information Institute.

What Happens If You Miss the Deadline
When no response is filed, the judge can treat the motion as unopposed and grant it. That is not a technicality. If the motion asks to change your custody schedule, modify your support payments, or restrict your parenting time, the court can approve all of it without hearing from you. Judges are not required to rule in the moving party’s favor on an unopposed motion, but they frequently do, especially when the request appears reasonable on its face and nobody has offered a reason to deny it.
Filing late doesn’t get you back to safety. The other party can ask the court to strike your response as untimely and have the judge disregard it entirely. Whether a late filing is accepted is up to the judge. Some are lenient about a day or two; others enforce deadlines strictly. You do not want to be in the position of hoping yours is the forgiving type.
There is a distinction worth understanding between an unopposed motion and a default judgment. Failing to respond to the initial petition or complaint that started the case can lead to a default judgment resolving the entire case against you. Failing to respond to a motion inside an existing case is less catastrophic but still serious: the court rules on that specific issue without your input, and the ruling becomes an order you must follow.
Reversing an Order After a Missed Deadline
If you missed the deadline and the court granted the motion, you may be able to file a motion asking the court to set aside or vacate the order. Under the federal model that most states mirror, a court can grant relief from an order based on mistake, inadvertence, surprise, excusable neglect, newly discovered evidence, or fraud. For excusable neglect, you generally must file within a reasonable time and no more than one year after the order was entered.3Legal Information Institute. Federal Rules of Civil Procedure Rule 60 – Relief from a Judgment or Order
Courts evaluating whether to set aside an order typically look at whether the failure to respond was willful, whether the other party would be unfairly harmed by reopening the issue, and whether you have a legitimate defense worth hearing. “I forgot” or “I was busy” almost never qualifies as excusable neglect. A medical emergency, a problem with service where you never actually received the papers, or an attorney’s serious error might. Getting an order set aside is an uphill fight, and courts are reluctant to undo decisions and restart proceedings. Responding on time, even with an imperfect filing, is far easier than trying to undo the damage afterward.
