Frequently Asked Questions
Child Support in Minnesota
Discover what you need to know about Child Support Laws in Minnesota.
Minnesota calculates child support under the state’s Income Shares guidelines. The court uses both parents’ gross incomes (combined parental income for determining child support), the number of joint children, and the cost of raising a child at various income levels to determine a presumptive support amount.
Minnesota’s guideline framework includes three core support components:
Basic support (everyday living expenses)
Child care support (work- or education-related childcare)
Medical support (health care coverage/medical support)
Minnesota also applies a parenting expense adjustment based on the percentage of parenting time when applicable.
For an estimate tailored to your situation, you can use the Deliberately.ai child support calculator above—but only a court order is legally binding.
Child support in Minnesota is commonly influenced by:
Each parent’s gross income (used in the guideline calculation)
Number of joint children
Parenting time percentage (used for the parenting expense adjustment)
Work- or education-related childcare expenses
Health care coverage costs / medical support issues
Potential deviations when guideline support would be “unreasonable and unfair” under the statute’s modification/deviation concepts
Cases involving self-employment, irregular income, or disputed parenting time often require more detailed documentation and review.
There is no universal amount. The final number depends on:
Both parents’ income information (combined parental income for determining child support)
The guideline amount for the number of joint children
Parenting time percentage (if the parenting expense adjustment applies)
Childcare and medical support inputs
For a reliable estimate before filing or negotiating, use the Deliberately.ai calculator above—keeping in mind the court has final authority.
Minnesota defines a “child” for support purposes as:
Under 18, or
Under 20 if still attending secondary school, or
Any age if incapable of self-support due to a physical or mental condition
Practically, support often ends at 18, or later if the child is still in high school—but not past age 20 under the statutory definition.
Your specific court order language still matters.
Not necessarily automatically.
Wage withholding can continue unless properly updated/terminated.
Any arrears remain owed even after the support obligation ends.
It’s important to confirm termination procedures through the court/Friend of the Court before stopping payments.
Not necessarily automatically.
Wage withholding and enforcement processes may continue unless properly updated.
Arrears can remain owed even after the support obligation would otherwise end.
(Your termination steps depend on your order and enforcement setup.)
Yes. Minnesota allows child support modification when one or more listed circumstances makes the current order “unreasonable and unfair,” such as:
Substantially increased/decreased gross income of either parent
Substantially increased/decreased needs of a parent or the child
Changes in healthcare availability/costs
Work- or education-related childcare added or significantly changed
Extraordinary medical expenses not addressed in the order
Modifications generally apply prospectively (from the date relief is requested), not retroactively to already-owed support.
Timeframes depend on:
Whether the case is uncontested
Court scheduling and county processing
Whether income, parenting time, or expenses are disputed
Uncontested cases may resolve in weeks to a few months; contested cases can take longer.
Minnesota’s guideline support framework includes:
Basic support
Child care support
Medical support / health care coverage obligations
It can—but only if:
Those costs are included in the guideline components/inputs, and
The court order accounts for them.
Paying expenses outside the order does not automatically reduce your obligation.
Minnesota’s guidelines use gross income concepts within the income-shares framework, starting with both parents’ gross incomes to determine combined parental income for support.
If a parent is voluntarily unemployed or underemployed, courts can address that within guideline application and case-specific findings.
Nonpayment may trigger enforcement tools (often through county child support enforcement), including income withholding and other collection actions. Arrears can build until paid.
Arrears generally:
Remain owed until paid in full
May be collected through enforcement tools
Do not simply disappear when the child ages out
Child support cases are handled through Minnesota’s court process and/or local child support enforcement (depending on the situation). If income, parenting time, or expenses are likely to be contested, consulting a Minnesota family lawyer before filing can help prevent delays and mistakes.
Yes—income withholding is common, and additional enforcement tools may be used depending on the case.
Not automatically.
Minnesota uses a parenting expense adjustment based on the percentage of parenting time (scheduled time averaged as the statute describes).
Income differences still matter, and support may still be owed even with substantial parenting time.
Minnesota’s statutory definition can extend support:
Up to under age 20 if still in secondary school
Potentially longer for a child incapable of self-support due to a physical or mental condition
College support is not automatic and typically requires specific legal grounds or agreements.
Parents generally cannot privately override a court order. Any change must be approved through the proper legal process to be enforceable.
A lawyer is not required for straightforward cases, but it’s strongly recommended when:
Income is disputed or self-employment is involved
Parenting time is contested
Arrears exist
A deviation is requested
You will typically need:
Recent pay stubs
Tax returns
Proof of health insurance costs
Childcare documentation
Existing court orders
Incomplete financial documentation is a common cause of delays.

How Long Does a Child Support Modification Take in Louisiana?
Michigan calculates child support using the Michigan Child Support Formula (MCSF), which Michigan courts are required to use when setting or changing child support.
Michigan’s approach is based on an income-shares model, meaning the formula estimates what parents would have contributed toward the child if they lived together, then allocates responsibility between parents.
The calculation is based on:
Both parents’ incomes (used to determine each parent’s support share)
Number of children
A statewide support schedule/formula inputs (per MCSF)
Parenting time / overnights (Michigan applies a parental time offset when overnights can be determined)
Medical support (health insurance and ordinary medical considerations)
Work-related childcare expenses
Other adjustments and court-approved deviations under the MCSF
