3.2 Since entry of the Current Order, the Parties have substantially complied with their respective obligations except as otherwise set forth herein.
4. GROUNDS FOR MODIFICATION
4.1 Since the date of the Current Order, the following changed circumstances have occurred, including but not limited to:

6. REQUESTED RELIEF
Petitioner respectfully requests that the Court enter an Order that:
6.1 Finds that the pleaded changed circumstances warrant modification.
6.2 Vacates the child-support provisions of the Current Order and substitutes a Modified Child Support Order obligating [Obligor] to pay $[___] per [frequency] commencing [MM/DD/YYYY], plus:
a. Allocation of reasonable and necessary unreimbursed medical expenses exceeding the $250 per-child annual amount included in the basic schedule, in proportion to combined monthly adjusted gross income under S.C. Code Regs. § 114-4720(A)(12), with regularly recurring extraordinary expenses treated under (A)(13) without duplicate reimbursement;
b. Continuation of health-insurance coverage for the Child(ren);

6.5 If warranted, orders future exchange of specified income records [DOCUMENTS / PROPOSED FREQUENCY / PROPOSED DELIVERY EVENT]. This is a requested order term; no statewide annual April deadline is asserted.
6.6 Awards suit money, including reasonable attorney’s fees, if the pleaded request is well-founded under S.C. Code § 63-3-530(A)(38), based on [SUPPORTING FACTS AND AMOUNT].
6.7 Grants such other and further relief as the Court deems just and proper.
7. ENFORCEMENT MECHANISMS
7.1 Income Withholding & Wage Garnishment: As set forth above.
7.2 Later changes. A later income change may support a properly filed and served modification action under S.C. Code § 63-17-310 or an applicable agency review. Any later adjustment requires the applicable court or agency action.
7.3 Separate enforcement requests, if any: [IDENTIFY EXISTING ARREARS, AGENCY INVOLVEMENT, REQUESTED REMEDY AND CURRENT AUTHORITY / NONE]. Tax intercept, reporting, license action or contempt is not initiated by this Petition alone. Any enforcement relief must follow its applicable notice, hearing and proof requirements.

Family law covers the paperwork that shapes divorce, custody, child support, adoption, guardianship, and other family matters. These filings are emotional and high-stakes, and they also have to meet strict procedural rules for service, financial disclosure, and parenting plans. Clean, accurate paperwork keeps the focus on getting a workable outcome for the family instead of getting derailed by technical problems that delay hearings or force amended filings.
