Changes in Child Support Over Time

Child support usually changes automatically to reflect the cost of living. But the court also can modify original child support orders under certain circumstances.

Most judges include a cost-of-living adjustment (COLA) clause in divorce decrees to eliminate the need for revisiting the order every time the Consumer Price Index goes up. In Minnesota, basic support orders require a COLA every two years.

Besides cost-of-living increases, child support can be adjusted to reflect specific circumstances.

The court may subsequently change the initial child support order if:

Unmarried Parents and Child Support

Unmarried mothers seeking child support must first take steps to legally establish the paternity of the child. The father may submit to a paternity test voluntarily or by court order following a lawsuit by the mother. Once paternity is established, the court will issue a child support order in a manner similar to that in a divorce.

For more information on these issues in Minnesota, see Paternity and Unmarried Parent Resources.

For specific information on the rights of unmarried fathers in Minnesota, see the Central Minnesota Legal Services publication, Unmarried Fathers’ Guide to Paternity, Custody, Parenting Time and Child Support in Minnesota.

Interstate Moves and Child Support

When a non-custodial parent moves to another state, a custodial parent may have to rely on the Uniform Interstate Family Support Act to implement or ensure payment of child support. This federal act provides the mechanisms by which a support order issued in one state can be transferred to, and enforced in, another state. For more information, visit the U.S. Department of Health and Human Services website. Uniform Interstate Family Support Act 1996.
