Michigan Spousal Support (Alimony) Laws: How It Works (2026)

Michigan uses the term "spousal support" rather than alimony. Courts award it on a purely discretionary basis under MCL 552.23, weighing a 14-factor test that traces to Ianitelli v Ianitelli, 199 Mich App 641 (1993), and Thames v Thames, 191 Mich App 299 (1991), and is commonly restated in Olson v. Olson, 256 Mich App 619 (2003). There is no statutory formula.

What is spousal support in Michigan?

Spousal support is a court-ordered payment from one spouse to the other after a divorce or legal separation. Michigan law uses the phrase "spousal support" consistently in modern court forms and practice, though the older term "alimony" still appears in several statutes.

MCL 552.13 is the foundational grant of authority. It allows the court to "require either party to pay alimony for the suitable maintenance of the adverse party." The statute also allows the court to terminate an alimony award as of the date the recipient remarries, unless the divorce judgment states otherwise, but termination requires the paying spouse to petition the court rather than happening automatically.

MCL 552.23 sets the governing standard for final awards. When the property divided in a divorce is not sufficient to suitably support either party, the court may award "spousal support out of the real and personal estate" in whatever amount it considers "just and reasonable." The court must consider the ability of either party to pay, the character and situation of the parties, and all other circumstances of the case.

Spousal support is separate from child support. It compensates a spouse for economic disadvantage caused by the marriage or its dissolution, not for child-rearing costs. Michigan child support follows a separate statutory formula. See Michigan child support laws for a full explanation of those rules.

How Michigan courts decide spousal support (the Olson v. Olson factors)

Because MCL 552.23 provides no formula, Michigan courts have developed a multi-factor framework through case law. The 14-factor test traces to Ianitelli v Ianitelli, 199 Mich App 641 (1993), and Thames v Thames, 191 Mich App 299 (1991), and is commonly restated in Olson v. Olson, 256 Mich App 619 (2003), which lists the factors a trial court must consider and make findings on when ruling on spousal support. Michigan's often-cited Sparks v. Sparks, 440 Mich 141 (1992), is a separate, related decision: it is the Supreme Court's leading case on dividing marital property and whether fault may be weighed in that division, not the source of this spousal-support factor list.

The factors include:

1. The past relations and conduct of the parties
2. The length of the marriage
3. The ability of the parties to work
4. The source and amount of property awarded to the parties in the divorce
5. The age of the parties
6. The ability of the parties to pay spousal support
7. The present situation of the parties
8. The needs of the parties
9. The health of the parties
10. The prior standard of living and whether either party is responsible for the support of others
11. Contributions to the marital estate
12. A party's fault in causing the divorce
13. The effect of cohabitation on a party's financial status
14. General principles of equity

A court does not weigh every factor equally. It considers the full picture of the marriage and each spouse's circumstances. The main objective, as courts have stated, is to balance the incomes and needs of the parties in a way that will not impoverish either.

Fault in causing the divorce is its own enumerated factor (factor 12 above), separate from the general category of past relations and conduct. Michigan courts have consistently held that fault should not receive disproportionate weight in the overall analysis, but it must be considered and addressed on the record.

The trial court must make specific findings on the relevant factors. An award that fails to address the applicable factors can be reversed on appeal.

The types of spousal support in Michigan

Michigan recognizes three functional types of spousal support.

Temporary (pendente lite) support is awarded while the divorce case is pending. It maintains the financial status quo during the proceedings so that neither party is left without support before the final judgment. Temporary support does not automatically continue after judgment; the court sets final support independently.

Periodic spousal support is the most common form of ongoing award after judgment. The court orders the paying spouse to make regular payments (typically monthly) over a specified period or indefinitely. Periodic support is modifiable under MCL 552.28 upon a showing of changed circumstances.

Alimony in gross is a fixed-sum award, either paid in one lump sum or in installments of a defined total amount over a specific time. Michigan courts define alimony in gross as "a sum certain" payable in a definite amount. Because the total obligation is fixed, alimony in gross is generally non-modifiable. Courts have held it can be modified only upon a showing of fraud. The non-modifiable character gives both parties finality and is often preferred in negotiated settlements.

For long marriages where one spouse has significantly lower earning capacity, a court may award long-term or even permanent periodic support. For shorter marriages or situations where a spouse needs time to become self-supporting, a time-limited periodic award is more typical.

How much and how long

Michigan courts have complete discretion on amount and duration. There is no statutory cap, no percentage guideline, and no formula written into the law.

Some Michigan courts have used a non-binding software tool called the Michigan Spousal Support Prognosticator as a starting point for settlement discussions. That tool generates a suggested range based on inputs such as income, length of marriage, and other variables. It is not a statute and it is not binding. A court may depart from its output, and many do. Parties and attorneys use it as one data point among many, not as the answer.

Amount typically reflects the gap between what the supported spouse can earn independently and what they need based on the marital standard of living. Duration often corresponds to the length of the marriage and the time a spouse needs to gain skills or re-enter the workforce.

For marriages of 20 or more years, courts more readily award longer-term or open-ended support. For marriages of fewer than five years, short rehabilitative support is more common. Between those ranges, the outcome depends heavily on the specific facts, the judge, and effective advocacy.

When spousal support ends or changes

Remarriage. Under MCL 552.13, periodic spousal support does not end automatically when the recipient remarries. The paying spouse must petition the court to terminate it; if the court grants termination, it takes effect as of the date of remarriage unless the divorce judgment expressly provides otherwise. Payments that accrued before the remarriage remain owed and collectible.

Death. Periodic spousal support generally terminates on the death of either party unless the judgment states otherwise. Alimony in gross, because it is a fixed vested obligation, may survive as a debt of the estate depending on how the judgment is written.

Cohabitation. Michigan does not have a statute that automatically terminates support on cohabitation, but cohabitation is one of the Olson factors. If the supported spouse's financial situation has materially improved because of a cohabiting relationship, the paying spouse can petition under MCL 552.28 for a reduction or termination based on changed circumstances.

Modification under MCL 552.28. Either party can petition the circuit court to modify a periodic spousal support award by showing a change in circumstances since the original judgment. Courts have broad authority to revise the amount, frequency, or duration of payments. Alimony in gross is not subject to modification except for fraud.

Retirement and job loss. A substantial and involuntary change in the paying spouse's income can qualify as a changed circumstance justifying modification. Voluntary income reduction, such as early retirement at an unusually young age, may receive less deference.

Is spousal support taxable in Michigan?

Michigan income tax generally conforms to federal adjusted gross income, so the federal treatment drives the state tax result for most taxpayers.

Federal rule for agreements signed after December 31, 2018. The Tax Cuts and Jobs Act eliminated the federal deduction for alimony payments and excluded receipt of alimony from the recipient's gross income. For any divorce or separation agreement executed after 2018, the payer cannot deduct spousal support, and the recipient does not report it as income. This applies to all new Michigan divorces as of 2026.

Federal rule for agreements signed before January 1, 2019. Agreements executed before 2019 retain the old rules: the payer deducts payments, and the recipient includes them as taxable income. If such an agreement is modified after 2018 and the modification expressly states that the new tax rules apply, the switch to the post-TCJA treatment takes effect from the modification date forward.

For authoritative guidance on the federal rules, see IRS Topic No. 452 and IRS Publication 504.

Spousal support vs. property settlement. Property transfers incident to divorce are generally not taxable events for either party. Labeling a payment as spousal support rather than a property settlement has significant tax consequences and should be addressed explicitly in any settlement agreement.

Spousal support vs. child support. Child support is never deductible and never taxable income. If a single payment is designated as both child support and spousal support, the IRS treats any amount that falls on a child-related contingency as child support. See Michigan child support laws for details on how child support is calculated separately.
