Michigan divorce laws: no-fault, property division, and spousal support
Michigan is a pure no-fault divorce state. You do not need to prove wrongdoing to end your marriage. At least one spouse must have lived in the state for 180 days before filing. Property is divided equitably (not automatically 50/50), and spousal support decisions hinge on up to 14 court-reviewed factors, with marriage length carrying significant weight.
Quick answer
Michigan is a pure no-fault divorce state, meaning you need only show your marriage has broken down beyond repair. Property is divided equitably based on contributions and circumstances, not automatically split in half. Spousal support is not guaranteed, but marriages lasting 20 or more years, especially those where one spouse stepped away from a career, carry a meaningfully higher likelihood of a long-term or permanent award.
Michigan's no-fault divorce system
Michigan requires only one thing to file for divorce: a declaration that your marriage has broken down beyond any reasonable likelihood of being saved. That is the entire legal threshold. You do not need to prove infidelity, abuse, abandonment, or any other wrongdoing.
This makes Michigan a pure no-fault state, and it has real consequences for how your case unfolds. Because fault does not determine whether a divorce is granted, a spouse who refuses to agree cannot stop the process. They can slow things down by contesting individual issues, but the marriage will be dissolved if you want it to be.
That said, "no-fault" does not mean a spouse's conduct is irrelevant to everything. Michigan law allows judges to consider marital behavior when deciding how to divide assets and whether to award spousal support. A spouse who wasted marital assets, concealed income, or engaged in financial misconduct may receive a smaller share of property as a result. Fault is one factor among many, and it cannot be the only basis for a punitive outcome, but it is very much in play.
Key distinction
No-fault means fault cannot stop your divorce. It does not mean fault is invisible to the court when deciding what each spouse walks away with.
Residency and filing requirements
Before you can file for divorce in Michigan, at least one spouse must have lived in the state for a minimum of 180 days, and in the county where you plan to file for at least 10 days immediately before filing. You do not both need to be Michigan residents, and there is no requirement to live apart before filing.
The divorce is filed with the Family Division of the Circuit Court in the appropriate county. The person who files is called the Plaintiff; the other spouse becomes the Defendant. These labels carry no moral implication. After filing, the Defendant must be formally served with the Summons and Complaint for Divorce, and they have a set window to respond.
| Requirement | Rule | Notes |
|---|---|---|
| State residency | 180 days minimum | One spouse only — not both |
| County residency | 10 days before filing | File in county where either spouse meets this rule |
| Grounds required | Irretrievable breakdown | No proof of fault needed |
| Filing fee | ~$175–$255 | Higher when minor children are involved; varies by county |
| Separation required? | No | You can file while still living together |

Mandatory waiting periods
Michigan law imposes a waiting period between the date you file and the earliest date a divorce can be finalized. The length depends on whether you have minor children.
No minor children: 60-day minimum
If you and your spouse have no children under 18, your divorce cannot be finalized any sooner than 60 days from the date of filing. In practice, uncontested divorces with no children can often be completed relatively close to that window. Contested cases take longer depending on the complexity of the issues involved.
With minor children: 180-day minimum
When the marriage involves children under 18, state law requires a full 180-day waiting period from the filing date. This longer window is designed to give parents time to develop custody arrangements, parenting plans, and support agreements. A judge can shorten this period if waiting the full six months would cause unusual hardship, but such waivers are granted selectively.
Separate maintenance: an alternative to divorce
Michigan also recognizes "separate maintenance," which resolves property, custody, and support issues without legally ending the marriage. It is sometimes chosen for religious reasons or to preserve health insurance benefits. Note that a separate maintenance judgment does not result in a divorce, and a new filing would be required to actually dissolve the marriage later.

How Michigan divides marital property
Michigan is an equitable distribution state, not a community property state. That means assets and debts accumulated during the marriage are divided fairly, based on the specific circumstances of your case. Fair does not always mean equal. The court has wide discretion to award unequal splits when the facts justify it.
What counts as marital property?
Marital property is generally everything acquired during the marriage, regardless of whose name is on the title or account. This includes income, real estate, retirement accounts, investment portfolios, vehicles, and debt. The name on a bank account matters less than when the funds were deposited and how they were used. For instance, if one spouse opened an account before the marriage but both spouses routinely drew from it, a court may treat it as marital property.
What stays separate?
Separate property includes assets you owned before the marriage and kept genuinely separate throughout it, as well as gifts or inheritances received in your name alone during the marriage. The key word is "separate." Assets that were commingled with marital funds or used for joint purposes can lose their separate character over time. A family inheritance that went into a joint account used for household expenses, for example, may be treated as marital property.
What factors does the court consider?
Judges weigh a range of circumstances when deciding what equitable distribution looks like in a given case, including:
- Length of the marriage
- Each spouse's contributions, financial and non-financial (including raising children or supporting a spouse's career)
- Each spouse's current and future earning capacity
- The needs of any children
- Whether a spouse wasted, hid, or dissipated marital assets
- Any prenuptial or postnuptial agreements
Watch out for this
Marital debt follows the same rules as marital property. A judge's order divides the debt between you and your spouse, but creditors are not bound by that order. If your name is on a joint account and your ex-spouse stops paying, the creditor can still come after you. Closing or refinancing joint accounts as part of your divorce agreement is essential protection.

Spousal support: what Michigan courts actually weigh
Spousal support (also called alimony) is not automatic in Michigan. It is not tied to a fixed formula, and there is no statewide calculator. Whether it is awarded, how much it is, and how long it lasts are all determined by a judge applying up to 14 statutory factors to the specific facts of your case.
The factors include the length of the marriage, each spouse's age and health, earning capacity, career interruptions, contributions to the household (including non-financial ones like childraising), the property each spouse receives in the divorce, the prior standard of living, and each spouse's conduct during the marriage. Fault can influence the outcome, but it cannot be the sole justification for an award or denial.
Types of spousal support in Michigan
- Temporary support (pendente lite): Covers the lower-earning spouse's needs while the divorce is pending. Ends when the final judgment is entered.
- Rehabilitative support: Short-term support intended to help a spouse gain education, credentials, or job skills needed to become self-sufficient. Duration is tied to a specific milestone or timeframe.
- Periodic support: Ongoing monthly or annual payments following the divorce, subject to modification if circumstances change significantly.
- Permanent support: Rare, but possible in long-term marriages where one spouse has limited ability to become financially independent due to age, health, or an extended career gap.
- Lump-sum support: A one-time payment, sometimes structured through a larger share of the marital assets rather than ongoing cash payments.
Spousal support automatically ends in Michigan when either party dies or when the recipient remarries, unless the judgment specifically states otherwise. Cohabitation with a new partner can also trigger a modification, though courts do not treat cohabitation as an automatic termination event.

Divorce after 20 or 30 years: what changes
The length of a marriage is one of the most consequential factors in a Michigan divorce. The legal process itself follows the same rules regardless of how long you were married. What changes is how courts weigh the evidence when deciding property, spousal support, and retirement asset division.
Spousal support after a long marriage
Michigan courts are significantly more likely to award spousal support in marriages of 20 years or more, and the duration of any award tends to be longer. In marriages of 30 or more years where one spouse stepped away from a career to raise children or support the other spouse's professional advancement, a permanent or near-permanent award is a realistic outcome. The logic is straightforward: re-entering the workforce after decades is genuinely difficult, and the court does not expect someone to do so with no financial bridge.
A common informal benchmark used by Michigan practitioners is roughly one year of support for every three years of marriage, though judges are not bound by any formula. For very long marriages with significant income disparity, that ratio can extend considerably.
Gray divorce considerations
Divorces after age 50 involve unique financial challenges. Retirement accounts, Social Security benefits, pension plans, and health insurance continuity all require careful attention. A Certified Divorce Financial Analyst (CDFA) can be invaluable for mapping out long-term financial outcomes before you agree to any settlement.
Retirement accounts and QDROs
In long marriages, retirement savings are often the most valuable marital asset. The portion of a retirement account accumulated during the marriage is marital property subject to equitable distribution. Dividing a 401(k), pension, or other qualified plan requires a separate court order called a Qualified Domestic Relations Order (QDRO). This document instructs the plan administrator how to split the benefit. Without a properly drafted QDRO, the division may not be recognized, and the receiving spouse could be left without their share.
Tax implications of support awards after 2018
For divorces finalized after December 31, 2018, federal tax law no longer allows the paying spouse to deduct alimony payments, and the receiving spouse no longer reports them as taxable income. This shift matters in long-term marriages where support amounts are significant. Both parties should understand the after-tax impact of any proposed support arrangement before agreeing to it.
Child custody and support overview
When a Michigan divorce involves children under 18, the court's analysis of custody, parenting time, and support is governed by a separate set of legal standards designed around the best interests of each child.
Legal and physical custody
Legal custody refers to the right to make major decisions about a child's education, healthcare, and religion. Physical custody refers to where the child primarily lives. Both can be shared (joint) or awarded primarily to one parent (sole). Michigan courts consider 12 statutory best-interest factors when deciding custody, including the love and affection each parent has for the child, each parent's capacity to provide emotional guidance, the child's established life pattern, and each parent's willingness to support the child's relationship with the other parent. Domestic violence is explicitly considered under Michigan law.
Child support
Unlike spousal support, child support in Michigan is calculated using a specific statewide formula that factors in both parents' incomes, the number of overnights each parent has, and certain child-related expenses. The formula was updated with clarifications for 2025, particularly around income calculations for self-employed parents and parents with variable income. Child support is enforced through the Friend of the Court (FOC), the administrative arm of Michigan's family court system. Payments are typically withheld directly from the paying parent's paycheck.

Frequently asked questions about Michigan divorce laws
Can my spouse stop the divorce from happening in Michigan?
No. Michigan is a pure no-fault state, which means only one spouse needs to want the divorce. A spouse who refuses to participate can slow the process by contesting individual issues or missing deadlines, but they cannot prevent the court from ultimately granting the divorce. If a spouse fails to respond to the complaint after being properly served, a default can be entered and the case can proceed without them.
Is Michigan a 50/50 divorce state?
No. Michigan uses equitable distribution, which means marital property is divided fairly but not automatically equally. The court weighs each spouse's contributions, earning potential, the needs of any children, and other circumstances. A 50/50 split is a common outcome in many cases, but it is not guaranteed, and judges have significant discretion to adjust when the facts call for it.
How long does it take to get divorced in Michigan?
At minimum, 60 days if there are no minor children, or 180 days if there are. In practice, uncontested divorces with no children can sometimes be finalized relatively close to the 60-day window, while contested divorces or those involving complex assets and custody disputes can take a year or more. The more issues you and your spouse can agree on before filing, the faster and less expensive the process tends to be.
Does cheating affect a divorce in Michigan?
Infidelity does not determine whether you can get divorced, because Michigan is a no-fault state. However, it can influence how a judge weighs property division and spousal support. A spouse's conduct during the marriage is one of the factors courts may consider, particularly when the conduct caused financial harm. Fault alone cannot drive a punitive outcome, but it is a legitimate part of the factual picture the court evaluates.
Will I receive spousal support if I was married for 30 years in Michigan?
Marriage length is one of the most significant factors in Michigan spousal support decisions. After a 30-year marriage, particularly one where one spouse reduced or left their career to support the family, courts are meaningfully more likely to award long-term or even permanent support. The amount and duration still depend on both spouses' incomes, health, earning capacity, and the property each receives. Nothing is automatic, but the longer the marriage and the greater the financial disparity, the stronger the case for substantial support.
Can I change my name when I get divorced in Michigan?
Yes. Michigan allows either spouse to request restoration of a former name as part of the divorce judgment at no additional cost. You simply need to include the request in your Complaint for Divorce or raise it before the final hearing. Once the judgment is entered, you can use it to update your name with the Social Security Administration and the Michigan Secretary of State. A 2025 law update also simplified name change procedures for individuals with criminal records by eliminating the presumption of fraudulent intent.
What is the difference between divorce and separate maintenance in Michigan?
Separate maintenance is Michigan's version of legal separation. It resolves property, custody, and support issues without officially ending the marriage. Couples who choose this path often do so for religious reasons or to preserve health insurance benefits tied to marital status. The legal process is nearly identical to divorce. However, at the end of it you are still legally married, and a new filing would be required to actually dissolve the marriage later. If your spouse files a counterclaim for divorce during a separate maintenance proceeding, the court must treat the case as a divorce.
