Child Support Calculation Worksheet

This template provides the substantive content and calculation methodology to help you
prepare — but you must transfer your figures to the official worksheet before filing.
The official form is available at https://www.courts.maine.gov/courts/family/divorce-separation/child-support.html.

10. MAINE-SPECIFIC NOTES
- Income Shares Model: Maine uses the Income Shares Model, considering both parents' adjusted gross incomes to determine the total support obligation (19-A M.R.S. § 2006).
- Means-Tested Benefits Excluded: Means-tested public assistance (TANF, SSI, SNAP, general assistance) is excluded from gross income (19-A M.R.S. § 2001(5)).
- Enhanced Support Obligation: Maine provides for an enhanced support entitlement in certain circumstances, calculated separately from the basic support and not including child care, medical expenses, or health insurance (19-A M.R.S. § 2001(12-A)).
- Shared Parenting Adjustment: When both parents have the child at least 30% of overnights, the calculation may be adjusted to reflect shared parenting costs.
- Modification: Either party may seek modification upon a showing of substantial change in circumstances.
- Interest: Overdue child support accrues interest at the rate established by the State Treasurer.

About This Template
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.
