⚖ 50/50 Custody in Minnesota
Does Child Support Apply With 50/50 Custody in Minnesota?
In most cases, yes. Minnesota does not automatically eliminate child support with equal parenting time.
✓General rule: With 50/50 custody, the higher-earning parent typically pays the lower-earning parent. The amount is reduced vs sole custody but rarely reaches $0.

Key rules, age cutoffs and what you need to know in Minnesota.
FORMULA How Minnesota Calculates Child Support
Minnesota Statutes Section 518A.34 governs child support. Minnesota uses Income Shares with parenting expense adjustments beginning when the paying parent has 10% or more of parenting time. Support may extend to 20.
AGE When Does Child Support End in Minnesota?
Child support in Minnesota ends when the child turns 18 — or high school graduation, whichever is later (20 max). Support also ends upon the child’s death, marriage or emancipation. Important: In most cases support does not stop automatically — you need a court order. Stopping payments without a court order creates arrears even after the child reaches the cutoff age.
INTEREST Arrears Interest in Minnesota
Minnesota charges 12% annual interest on unpaid child support arrears. Minnesota’s rate of 12% is among the higher rates in the country. There is generally no statute of limitations on child support debt.
ENFORCEMENT Minnesota Child Support Enforcement
Minnesota has broad enforcement powers including wage garnishment, tax refund interception, driver’s license suspension, professional license suspension, passport denial, and credit bureau reporting. Criminal charges may apply for significant or long-term non-payment.
MODIFY Modifying Child Support in Minnesota
Child support can be modified in Minnesota when there is a material and substantial change in circumstances — typically a significant income change, job loss, new children from another relationship, or change in custody. Most states also allow a periodic review every 3 years. File a petition with the court — private agreements to change support are not legally enforceable.
