Michigan does not offer "legal separation" by that name. Instead, Michigan provides separate maintenance under Mich. Comp. Laws § 552.7, which divides property, sets support, and resolves custody while keeping the couple legally married. Divorce, under Mich. Comp. Laws § 552.6, legally ends the marriage. Both cost $175-$255 to file in 2026 and follow nearly identical procedures.
The central choice between legal separation vs divorce Michigan residents face comes down to one fact: separate maintenance keeps you married (preserving health insurance and certain benefits in some cases), while divorce dissolves the marriage and lets you remarry. This guide explains both options, the exact statutes, filing fees, residency rules, and waiting periods so you can decide which path fits your situation.

What Is Legal Separation in Michigan?
Michigan has no statute called "legal separation"—the equivalent legal process is "separate maintenance" under Mich. Comp. Laws § 552.7. Separate maintenance is a court action that divides marital property and debt, orders spousal support, and decides child custody, parenting time, and child support, yet leaves the couple legally married at the end. The filing fee is the same $175-$255 as divorce.
The statute requires that a separate maintenance action be filed "in the same manner and on the same grounds" as a divorce. That means the only ground is a breakdown of the marriage relationship under Mich. Comp. Laws § 552.6. When people search for the difference between separation and divorce in Michigan, the practical answer is that separate maintenance produces an enforceable court judgment addressing every financial and parenting issue a divorce would—property, debt, support, custody—but the spouses stay married. Because the marriage continues, neither party may legally remarry, and tax filing status typically remains married filing jointly or married filing separately. Couples often pursue this judicial separation route for religious reasons, to preserve health coverage, or to retain benefits tied to marital status.
What Is Divorce in Michigan?
Divorce in Michigan legally dissolves the marriage under Mich. Comp. Laws § 552.6, and it is the only process that lets either spouse remarry. Michigan is a pure no-fault state: the sole ground is "a breakdown of the marriage relationship to the extent that the objects of matrimony have been destroyed and there remains no reasonable likelihood that the marriage can be preserved." Filing costs $175-$255 in 2026.
No spouse must prove adultery, abandonment, or cruelty to obtain a divorce; stating the statutory breakdown language is sufficient. However, marital misconduct such as adultery can still influence how a judge divides property or awards spousal support, even though it is not required to grant the divorce itself. A Michigan divorce resolves the same categories of issues as separate maintenance—equitable property division, debt allocation, child custody and parenting time, child support, and spousal support—but ends with a Judgment of Divorce that terminates the marriage. After entry of that judgment, each former spouse becomes a single person for legal purposes, loses spousal health-insurance eligibility, and may remarry. Roughly 30,000-33,000 divorces are granted in Michigan each year, making it by far the more common of the two actions.
How Filing Fees Compare in 2026
Michigan divorce and separate maintenance filing fees are identical in 2026: $175 for cases without minor children and $255 for cases with dependent children under 18. The base fee of $150 is set by Mich. Comp. Laws § 600.2529, plus a $25 electronic filing fee, plus an $80 custody and parenting-time fee when children are involved. As of March 2026, verify with your local clerk.
The $80 difference between the two fee tiers exists because cases involving minor children require an additional payment to the Friend of the Court Fund under Mich. Comp. Laws § 600.2529. Some counties add local surcharges, so the total can vary slightly by jurisdiction. If you cannot afford the fee, Michigan courts grant fee waivers to households at or below 125% of federal poverty guidelines—approximately $19,506 for a single-person household in 2026—by filing a Fee Waiver Request (Form MC 20) with documentation of income, assets, and monthly expenses. Beyond the court filing fee, both actions carry similar attorney costs because the procedures are nearly identical; an uncontested matter may cost $1,500-$3,500 in legal fees, while a contested case can exceed $15,000-$25,000. The court filing fee itself does not change based on whether you choose separate maintenance or divorce.
Residency Requirements for Both Actions
Both divorce and separate maintenance in Michigan require the same residency: at least 180 days of Michigan residency plus 10 days in the filing county before filing, under Mich. Comp. Laws § 552.9. Only one spouse must satisfy these requirements. The 180-day rule establishes the court's jurisdiction; the 10-day county rule sets the proper venue (the specific Circuit Court).
The 180-day period does not require continuous physical presence if the person maintains an established domicile and intends to return—temporary absences for work, military service, or family emergencies do not break residency. A narrow statutory exception relaxes the county requirement in cases involving minor children at risk of being removed from the country. Because separate maintenance follows the identical jurisdictional rules, it offers no shortcut around the 180-day requirement; a person who has lived in Michigan fewer than six months cannot use separate maintenance to bypass the residency threshold for either action. Both actions are filed with the Circuit Court (Family Division) in the county where the residency conditions are met. If you have not yet met the 180-day requirement but need urgent orders, you would typically still have to wait, since the residency rule governs both the divorce and the separate maintenance route equally.
Waiting Periods: Identical for Both
Michigan imposes the same mandatory waiting periods on divorce and separate maintenance under Mich. Comp. Laws § 552.9f: 60 days when there are no minor children, and 6 months (180 days) when the couple has dependent children under 18. Both periods begin on the filing date, not the date of service. No case can finalize in fewer than 60 days.
The two periods are treated differently when it comes to exceptions. The 60-day period generally cannot be shortened—it is an absolute floor for any Michigan marital action. The 6-month period for cases with minor children, however, can be reduced to as few as 60 days when a party files a written motion demonstrating "unusual hardship or compelling necessity," such as documented domestic violence, military deployment, or terminal illness. Courts evaluate each petition individually and approval is not guaranteed. Because separate maintenance uses these identical timeframes, choosing it over divorce does not produce a faster resolution. In practice, uncontested matters of either type typically finalize within two to six months, while contested cases often run eight to twenty-four months depending on complexity and court scheduling.
Property and Debt Division in Both Actions
Michigan applies equitable distribution to both divorce and separate maintenance, meaning marital property and debt are divided fairly—though not necessarily 50/50—based on factors the court weighs. Both actions can fully resolve who keeps the house, how retirement accounts split, and who pays which debts. The legal standard is identical whether you choose separate maintenance under Mich. Comp. Laws § 552.7 or divorce under Mich. Comp. Laws § 552.6.
Michigan courts consider factors including the length of the marriage, each spouse's contributions to the marital estate, the parties' ages and health, earning abilities, and fault in the breakdown of the marriage. Separate (non-marital) property—such as inheritances or assets owned before marriage—is generally retained by the original owner in both proceedings, though it can become divisible if commingled or if the other spouse contributed to its growth. A key practical point: once a separate maintenance judgment divides property, that division is generally final. If a spouse later files for divorce, the court may adopt the existing separate maintenance orders and will not automatically let a party relitigate a property award already decided. For example, if one spouse received the marital home in the separate maintenance case, the other generally cannot use a later divorce filing to reverse that outcome. This finality makes the property decisions in a separate maintenance case just as consequential as those in a divorce.
Health Insurance: The Decisive Difference
Health insurance is often the single biggest reason couples choose separate maintenance over divorce in Michigan. Because separate maintenance keeps the couple legally married, a dependent spouse may be able to stay on the other spouse's employer health plan—coverage that ends after a divorce. After a Michigan divorce, you cannot keep a former spouse on your health insurance, forcing the dependent spouse onto COBRA, a marketplace plan, or their own employer coverage.
This advantage is real but not guaranteed, and it is entirely plan-dependent. Many employer plans cover a current spouse but exclude former spouses, so separate maintenance can preserve that coverage. However, some insurers treat a separate maintenance order as a qualifying "life event" that allows them to terminate or deny spousal coverage, and some plans will not honor spousal coverage if the spouses no longer live together. COBRA continuation after a divorce typically lasts up to 36 months but often costs $400-$700 or more per month in unsubsidized premiums, which is why preserving employer coverage through separate maintenance can be financially decisive. Other marital-status benefits—such as certain Social Security spousal benefits and some pension provisions—may also be preserved because the couple remains married. The consistent professional advice is to confirm coverage directly with the plan's HR department or insurer before choosing separate maintenance, because no statute forces an insurer to continue coverage.
Converting Separate Maintenance to Divorce
Converting a separate maintenance case to divorce is simple while the case is pending but complicated after judgment. While the separate maintenance action is open, either spouse can ask the court to proceed as a divorce; under Mich. Comp. Laws § 552.7, if the defendant files a counterclaim for divorce, the court must grant the divorce rather than separate maintenance. After a final judgment, however, Michigan requires filing a brand-new divorce action.
This is an important distinction from some other states that allow a simple motion to convert a finalized separation into a divorce. In Michigan, once a separate maintenance judgment is entered, there is no streamlined conversion; the spouse seeking divorce must start a fresh case and pay a new filing fee. The court may adopt the existing separate maintenance orders, which can preserve the prior property and support arrangements, but it is not automatically bound by them, and the new filing can reopen certain issues. One practical benefit is that the groundwork laid in the separate maintenance case—financial disclosures, parenting plans, and negotiated terms—often carries over and can speed the later divorce. The counterclaim rule also means a person cannot unilaterally force a spouse to remain merely separated; if either party wants a full divorce, Michigan law ultimately allows the divorce to proceed.
Which Option Is Right for You?
Choose separate maintenance if you need to preserve health insurance, retain marital-status benefits, or have religious objections to divorce while still legally dividing property and arranging support. Choose divorce if you want to legally end the marriage, remarry in the future, or achieve a clean financial break. Both cost $175-$255 to file in 2026 and follow the same 60-day or 6-month waiting periods.
The decision turns less on cost or procedure—which are nearly identical—and more on the desired end state of the marriage. Separate maintenance suits couples who want full legal resolution of property, debt, custody, and support but have a concrete reason to stay married, most often health insurance or Social Security spousal benefits. Divorce suits couples who want finality and the freedom to remarry. Be aware that separate maintenance offers no faster timeline, no lower filing fee, and no escape from the 180-day residency rule. Because either spouse can convert a pending separate maintenance case into a divorce by counterclaim, a person who wants to remain only separated cannot guarantee that outcome if the other spouse insists on divorce. Given how consequential—and often final—the property decisions are, consult a licensed Michigan family law attorney and your insurer before deciding.
