If an obligated parent does not pay child support, you may file a Petition to Enforce Child Support, Child Support Arrears and Medical Expense Reimbursement. Often, all three of those issues go together. It makes sense to include those three issues in one petition, because if the obligated parent is not paying child support, you will want to ask the court to enforce the child support order in effect. You will also want the obligated parent to pay for the months he/she did not pay, along with any medical expenses he/she did not pay. Also, be advised that it is appropriate in that petition to ask for the obligated parent to pay your attorney’s fees if you hire an attorney for this issue.
