How Spousal Support Is Calculated in Michigan
Spousal support in Michigan is determined by a statutory multi-factor analysis under MCL § 552.23. The court weighs the following factors to arrive at a fair support amount and duration. Unlike the temporary formula, there is no mathematical calculation for permanent support — it is a discretionary determination by the judge based on the totality of the circumstances.
The types of spousal support available in Michigan include: Temporary, Fixed-term, Permanent, Lump-sum. The type ordered depends on the length of the marriage, each spouse's financial situation, and the supported spouse's ability to become self-supporting.
