How Maine child support is calculated

Maine uses the Income Shares Model. Child support is calculated by determining the combined gross income of both parents and using the Maine Schedule of Basic Child Support Obligations (a table) to find a basic support amount. This amount is then adjusted for additional expenses such as health insurance premiums for the children, weekly childcare costs, and extraordinary medical expenses. Finally, each parent's share of the total support obligation is determined proportionally based on their percentage share of the combined adjusted gross income.

What can change your child support amount

Income changes

A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.

Childcare & insurance

Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.

Parenting time shifts

If the custody schedule changes significantly, support can be recalculated under Maine guidelines.

Child's special needs

Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.

Common questions

What people ask about child support

How long does a divorce take in Maine?

A divorce in Maine takes a minimum of 60 days after the complaint for divorce is served. However, most cases take longer, especially if there are disagreements on issues like property division or child custody.

Do I need a lawyer to get divorced in Maine?

While it's possible to file for divorce without a lawyer, especially in uncontested cases where both parties agree on all terms, it is generally recommended to consult with a lawyer, particularly if there are complex property issues, domestic violence, or significant disagreements.

Is Maine a no-fault divorce state?

Yes, Maine is a no-fault divorce state, meaning you can file for divorce based on "irreconcilable differences" without proving fault. However, Maine also recognizes fault-based grounds such as adultery, extreme cruelty, and desertion.

How is property divided in Maine divorce?

Maine follows the principle of equitable distribution, meaning marital property is divided fairly, but not necessarily equally, between the spouses. The court considers various factors, including each spouse's contribution to the acquisition of marital property, the value of property set apart to each spouse, and the economic circumstances of each spouse.

What is the automatic preliminary injunction in Maine divorce cases?

In Maine, an automatic preliminary injunction is imposed once a divorce complaint is filed (Title 19-A, § 903). This injunction prohibits both spouses from transferring, encumbering, concealing, or disposing of marital property, canceling insurance, incurring unreasonable debt, harassing the other party, or relocating children out of state without court approval.
