Michigan Motion To Modify Support Order for incarcerated Person is a legal document that is used when a person who is incarcerated and making payments for support arbitrages seeks to have the payment modified due to their changed circumstances. This type of motion is typically filed in the court that issued the original support order. The motion can be used to reduce the amount of payments or to suspend payments altogether. The motion must be accompanied by evidence of the changed circumstances such as proof of incarceration and proof of income. There are two types of motions: one to modify the amount of support payments and one to suspend support payments.
