How does alimony work in Michigan?

Federal & State Law Editorial TeamLast reviewed: 2026-04-30

Michigan spousal support is governed by MCL 552.13 and MCL 552.23 and is one of the most discretionary alimony regimes in the country — there is no statutory formula.

1. The Sparks Factors

The Michigan Supreme Court in Sparks v. Sparks, 440 Mich. 141 (1992), set out the 11 factors (since expanded in practice to 14) that govern spousal support:

  • Past relations and conduct of the parties
  • Length of the marriage
  • Abilities of the parties to work
  • Source and amount of property awarded
  • Ages of the parties
  • Abilities of the parties to pay alimony
  • Present situation of the parties
  • Needs of the parties
  • Health of the parties
  • Prior standard of living and whether either is responsible for support of others
  • Contributions of the parties to the joint estate
  • A party's fault in causing the divorce
  • Effect of cohabitation on a party's financial status
  • General principles of equity
  • 2. No Formula — But MARC Software

    Michigan does not have a statewide formula like New York or Illinois. However, many practitioners use the Michigan Alimony Recommendation Calculator (MARC) — privately published software that estimates support based on the Sparks factors. Courts may consider but are not bound by MARC outputs.

    3. Two Types

  • Periodic spousal support — paid in installments. Modifiable under MCL 552.28 unless made non-modifiable by agreement.
  • In gross (lump-sum) spousal support — fixed total amount. Generally not modifiable.
  • 4. Duration

    No statutory cap. Common patterns:

  • Short marriages (under 10 years): rehabilitative support, often 1-3 years
  • Mid-length (10-20 years): longer rehabilitative or modest periodic
  • Long marriages (20+ years): periodic support potentially indefinite
  • 5. Modification — MCL 552.28

    Periodic spousal support is modifiable on a change in circumstances. The threshold is significant but not extreme.

    6. Termination

    Unless the decree states otherwise, periodic spousal support terminates on:

  • Death of either party
  • Remarriage of the recipient
  • Cohabitation if the decree expressly so provides (it is critical to include this in the judgment)
  • 7. Fault

    Michigan is a no-fault divorce state but fault is one of the Sparks factors in setting spousal support. Adultery, abuse, or other misconduct can increase or decrease the award.

    8. Tax Treatment

    Federal TCJA applies — non-deductible/non-taxable for orders post-2018.

    When to Talk to a Lawyer
    • Fault evidence (adultery, abuse) may significantly affect support
    • You need to ensure the decree addresses cohabitation termination
    • You are negotiating periodic vs in gross support
