Contact your ex-spouse to work out any problem that is causing a default on obligations. Inform them of the obligations and indicate which areas they are falling short according to the divorce agreement. If you come to another agreement, file a motion asking the court to establish a new court order that reflects the new agreement. File this motion with the court clerk and wait for the new court orders. Send copies of the new agreement and court orders to your ex-spouse.
File a motion to enforce if there was no agreement reached when you contacted your ex-spouse. Visit the court where the final divorce agreement was issued and ask the court clerk for the "motion to enforce" forms. Indicate your divorce case number, your address and that of the other party. Explain your ex-spouse's obligations according to the agreement, and indicate the areas that they are defaulting on such as alimony, child support, or mortgage payments. Pay the filing fee.
Contact the judge to set a hearing date or in other jurisdictions you may have to wait for a hearing date to be confirmed to you through certified mail or electronic mail. As you wait for the hearing, gather proof in the form of witnesses and documents that support your claim of the other party's default on the agreement. The burden of proof lies upon you, therefore you need substantial evidence for the motion of enforcement to be successful.
Serve your ex-partner or his attorney with a copy of the motion to enforce as well as the time and date of the hearing. Attend the hearing during which the judge will listen to both sides and make a decision to either turn down the request or issue new court orders for your ex-spouse to comply with the agreement.
File for a motion for contempt if your ex-spouse fails to comply with the new court order after a set period of time. Through a motion for contempt the court will sanction your ex-spouse harshly through monetary fines or a jail term. Obligations in the agreement must still be met regardless of these sanctions. Follow the same procedure as filing for a motion to enforce by starting out at the court clerk's office.
