Free Child Support Demand Letter Template

A child support demand letter is a written request to a co-parent for support payments that are overdue. It sets out what is owed, over what period, and how you want the arrears handled.

The letter is a first step rather than an enforcement tool. A support obligation comes from a court order, and enforcing that order runs through the courts and your state’s child support enforcement agency. Sending a letter can prompt payment without either, which is why many parents try it first.

It also builds a record. If matters do escalate, a dated letter showing you asked clearly and allowed a reasonable chance to respond is worth having.

A demand letter suits situations where communication still works and the missed payments look like a solvable problem.

Consider sending one when:

• Payments have run late or partial and you want a clear written record.
• The other parent has had a change in circumstances and stopped communicating.
• Resolving this directly appeals more than opening a case file.
• You need documentation before approaching the agency or a court.

Skip the letter entirely when direct contact is unsafe or unwise. Go to your state’s child support enforcement agency instead if there is any history of abuse, intimidation, or a protective order, and let the agency or the court handle contact. That service is free, and choosing it is not an escalation you need to justify to anyone.

Tip: Keep support and parenting time separate. They are different matters, and withholding one to pressure the other tends to weaken your position rather than strengthen it. Ask the agency or an attorney before acting on that impulse.

Specific figures make a letter hard to argue with. Vague ones invite a dispute about arithmetic instead of a payment.

Pull together:

• A copy of the support order, including the amount and payment schedule.
• Payment history showing what arrived and when.
• Bank records or agency statements that corroborate the history.
• Any written agreement about modified or deferred payments.
• Earlier messages where payment was promised or discussed.

Work out the total owed and be ready to show your calculation. When the other parent disputes a figure, having the arithmetic on paper turns an argument into a correction.

If payments run through a state disbursement unit, request its records rather than relying on your own notes. Agency figures carry more weight than a personal spreadsheet.

Date-stamp your own records as you go. Reconstructing months of payment history under pressure is far harder than keeping a running note.

Our child support demand letter template covers each part below. Keep the tone factual throughout, since this letter may end up in front of a judge.

Your Details and the Children’s

Name yourself, the other parent, and the child or children the order covers.

The Court Order

Identify the order by case number, issuing court, and date, along with the amount and frequency it sets.

The Amount Owed

State the total arrears and the period they cover. Attach the payment history rather than reproducing it in the body of the letter.

What You Are Asking For

Say exactly what you want: payment in full by a date, a catch-up schedule, or a return to regular payments.

A Response Deadline

Give a specific date, and pick one that is genuinely reasonable.

What Happens Without a Response

State plainly that you will pursue enforcement through the appropriate channels. Avoid threatening any specific step unless you have confirmed it is actually available to you.

Signature and Date

Sign and date the letter, then keep a copy of everything you send.

Send the letter by a method that gives you proof of delivery, and file the receipt with your copy.

When a response arrives, get any agreement in writing. A promise made over the phone helps nobody later. Where you settle on a catch-up schedule, write down the amounts and dates and have both parents sign it.

When nothing arrives, or payments stop again, your state’s child support enforcement agency is the next step. It can open a case, locate a parent, establish or adjust amounts, and pursue arrears. A family law attorney is worth consulting when the situation is complicated or the sums are large. Many agencies let you start a case online, so ask what documents they want up front rather than sending things twice.

Tip: Keep everything in one place: the letter, the proof of delivery, the payment history, and any reply. Enforcement moves faster when the paperwork is already assembled.

None of this reflects on you. Chasing support you are owed is an ordinary thing to have to do, and these systems exist precisely because it happens often.

A child support demand letter is private correspondence. It carries no legal force on its own, and sending one changes neither the court order nor the amount owed.

Enforcement rules vary considerably by state, covering how arrears are calculated, which remedies exist, and what deadlines apply. Check your state’s official website and contact your state’s child support enforcement agency rather than relying on a general description.

Be careful about naming consequences in the letter. Describing an enforcement step you have not confirmed is available can undercut your credibility, so keep that language general unless you know the specifics for your state.

Talk to a family law attorney when the other parent disputes the order, lives in another state, has filed for bankruptcy, or when arrears have built up across years. A short consultation often clarifies which route is fastest.
