How to Write a Child Support Demand Letter

A direct written demand to the paying parent — before court action — serves two purposes: it gives them a chance to pay without litigation, and it documents their willful nonpayment if they ignore it.

What to Include

State: the total amount overdue (with the calculation period), the date by which payment must be received, that failure to pay will result in enforcement action (specify: contempt motion, bank levy, lien recording), and that you are preserving all legal rights. Send certified mail and keep a copy.

The demand letter starts the contempt clock. A paying parent who receives a written demand specifying the amount owed and ignores it is willfully failing to pay — strengthening your contempt case. The letter also creates a record that you made reasonable attempts to resolve the matter before burdening the court.
