Lump sum alimony in Michigan, legally called "alimony in gross," is a one-time or fixed-installment payment that satisfies a spouse's entire support obligation under Mich. Comp. Laws § 552.23. Unlike monthly support, it is non-modifiable under Mich. Comp. Laws § 552.28 and often involves a present-value discount of 10-20%.

What Is Lump Sum Alimony in Michigan?
Lump sum alimony in Michigan is a single fixed payment, or a defined series of installments totaling a definite sum, that completely discharges one spouse's support obligation. Michigan courts call this "alimony in gross" under Mich. Comp. Laws § 552.23. In Staple v. Staple, 241 Mich App 562 (2000), the Court of Appeals held that any alimony fixed at a definite total amount is alimony in gross rather than periodic support.
The defining characteristic of lump sum alimony is its certainty. The amount is fixed at the time of the judgment and does not change based on future events. This contrasts with periodic spousal support, which fluctuates and terminates upon the recipient's remarriage or either party's death. Michigan courts treat alimony in gross as functionally part of the property division rather than ongoing maintenance, which is why it carries different legal consequences than a monthly alimony buyout structured as periodic support. Because the obligation is satisfied upfront, neither spouse retains a continuing financial relationship after payment, making lump sum alimony attractive for couples seeking a clean financial break after divorce.
Lump Sum vs Monthly Alimony in Michigan
Lump sum alimony delivers the entire award in one payment, while monthly (periodic) alimony spreads payments over months or years and remains modifiable under Mich. Comp. Laws § 552.28. A one time alimony payment typically reflects a 10-20% present-value discount, whereas periodic support continues until remarriage, death, or a court modification based on changed circumstances.
The choice between lump sum vs monthly alimony involves significant trade-offs. A lump sum guarantees the recipient receives the full value regardless of the payer's future job loss, death, or bankruptcy. Periodic support, by contrast, can be reduced if the payer loses income under Gates v. Gates, 256 Mich App 420 (2003), which requires the moving party to prove changed circumstances. The table below compares the two structures across the factors that matter most to divorcing spouses in Michigan.
| Feature | Lump Sum (Alimony in Gross) | Monthly (Periodic) |
|---|---|---|
| Payment timing | One payment or fixed installments | Ongoing monthly payments |
| Modifiable? | No, under Mich. Comp. Laws § 552.28 | Yes, with changed circumstances |
| Ends on remarriage? | No, full amount still owed | Yes, terminates |
| Ends on death? | No, estate owes balance | Yes, terminates |
| Typical discount | 10-20% of stream value | None |
| Bankruptcy risk | Protected if true support | Future payments at risk |
| Best for | Clean break, distrust of payer | Lower upfront cost, flexibility |
How Lump Sum Alimony Is Calculated in Michigan
Michigan has no statutory formula for any alimony, including lump sum awards. Courts apply 14 factors from Sparks v. Sparks, 440 Mich 141 (1992), then negotiate a present-value figure. As an informal benchmark, Michigan attorneys estimate periodic support at roughly 30-40% of the income gap between spouses, with duration near one year of support per three years of marriage.
To convert a periodic stream into a one time alimony payment, the parties calculate the total expected payments and apply a discount. The Clarkston Legal example illustrates the math: if a payer owes $1,000 per month for 120 months, the total liability is $120,000. The payer might offer a lump sum of $102,000, reducing the obligation by $18,000, or 15%. This discount reflects the time value of money, the payer's elimination of risk, and the recipient's benefit of receiving funds immediately. The actual percentage depends on negotiation leverage, the marriage length, and the certainty of the underlying support award. Because no Michigan statute caps or mandates the discount, the buyout alimony agreement figure is whatever the two spouses accept as just and reasonable under Mich. Comp. Laws § 552.23.
The 14 Sparks Factors Michigan Courts Apply
Michigan judges weigh 14 factors from Sparks v. Sparks, 440 Mich 141 (1992), when deciding whether to award spousal support and in what amount. No single factor controls, and courts retain broad discretion under Mich. Comp. Laws § 552.23. These same factors govern whether a lump sum or periodic structure is appropriate.
The Sparks factors include the past relations and conduct of the parties, the length of the marriage, each party's ability to work, the source and amount of property awarded, the parties' ages, the parties' ability to pay support, the present situation of the parties, the needs of the parties, the parties' health, the prior standard of living, whether either party supports others, contributions to the joint estate, fault, and general principles of equity. Michigan is a no-fault divorce state, so while fault is one factor, adultery alone does not bar an award. The Michigan Supreme Court in Loutts v. Loutts described the purpose: "to balance the parties' incomes and needs so that neither party will be impoverished."
Is Lump Sum Alimony Modifiable in Michigan?
No. Lump sum alimony in Michigan is non-modifiable and exempt from change under Mich. Comp. Laws § 552.28, even if the recipient remarries or dies before all installments are paid. Courts in Oknaian v. Oknaian and Hall v. Hall confirm that alimony in gross cannot be altered for changed circumstances; the only narrow exception is proven fraud.
This non-modifiability is the defining legal feature of a lump sum alimony buyout. Because Michigan classifies alimony in gross as part of the property division, the standard modification rights that protect periodic-support payers do not apply. A payer who loses a job after agreeing to lump sum alimony remains fully obligated. Conversely, a recipient who later faces hardship cannot return to court for more. Importantly, Michigan judges cannot impose non-modifiable support on their own. Under Staple v. Staple, only the parties can waive modification rights through a clearly worded settlement agreement, and that waiver must state that the parties forgo their statutory right to petition for modification and agree the provision is final, binding, and nonmodifiable.
The Staple Waiver: Making Alimony Non-Modifiable
A "Staple waiver" is precise contract language, from Staple v. Staple, 241 Mich App 562 (2000), that makes negotiated spousal support non-modifiable. To be enforceable, the waiver must clearly state that both parties forgo their right under Mich. Comp. Laws § 552.28 to petition for modification and agree the support is final, binding, and nonmodifiable.
The Staple decision resolved a conflict in Michigan law by adopting a "modified approach": parties may contractually waive modification rights, but courts cannot. The waiver only applies to judgments entered from the parties' own negotiated settlement, never to support ordered after a trial on the merits. The danger of an unclear waiver appears in Keisling v. Keisling (2016), where a judgment ordered $1,000 monthly support but omitted binding non-modifiable language; the court therefore had to consider whether changed circumstances justified modification. For a lump sum alimony buyout to achieve true finality, the divorce judgment must contain explicit Staple-compliant language. Attorneys routinely caution clients that such waivers are powerful but irreversible: a payer who later cannot afford the obligation gets no relief, and a recipient cannot seek more.
Tax Treatment of Lump Sum Alimony in Michigan
For any Michigan divorce finalized after December 31, 2018, alimony, including a lump sum, is not tax-deductible for the payer and not taxable income for the recipient under the federal Tax Cuts and Jobs Act of 2017. This rule applies to all alimony structures, so a one time alimony payment carries no federal income tax for the receiving spouse.
The 2019 tax change significantly affects the economics of a buyout alimony agreement. Before 2019, payers could deduct alimony, which effectively subsidized larger payments and shifted tax to the lower-bracket recipient. Now, with no deduction available, payers fund alimony with after-tax dollars, and recipients keep the full amount tax-free. When negotiating lump sum vs monthly alimony, both spouses should account for this when calculating present value, because the absence of a deduction often pushes payers toward smaller, discounted lump sums. Michigan does not tax alimony separately at the state level beyond standard income rules. Because tax law is complex and individual situations vary, spouses considering a lump sum should consult a tax professional before signing, as the structure of the payment can affect estate and asset-transfer consequences.
Cost to File for Divorce in Michigan
The filing fee for divorce in Michigan is $175 for cases without minor children and $255 for cases with minor children, as of January 2026. Verify the exact amount with your county Circuit Court clerk, since fees vary slightly by county. Fee waivers are available under Michigan Court Rule 2.002 for filers who receive means-tested public assistance.
You file a Complaint for Divorce in the Family Division of the Circuit Court in your county of residence. Filers who cannot afford the fee submit Form MC 20, a Fee Waiver Request. The clerk must automatically approve the waiver for filers receiving SNAP/FAP, Medicaid/Healthy Michigan, SSI, TANF/FIP, WIC, or CHIP benefits. Filers not on public assistance qualify if their income falls at or below 125% of the federal poverty guidelines. Beyond the filing fee, costs may include attorney fees, mediation, and service of process. A contested case with disputed alimony, such as a fight over whether to structure support as a lump sum, typically costs far more in attorney time than an uncontested buyout where both spouses agree to the figure in advance.
Residency and Waiting Periods for Michigan Divorce
To file for divorce in Michigan, one spouse must have lived in Michigan for at least 180 days and in the filing county for at least 10 days before filing, under Mich. Comp. Laws § 552.9. The 180-day rule is jurisdictional, meaning courts cannot waive it. Only one spouse must satisfy these requirements.
Michigan also imposes a mandatory waiting period before any divorce, including one resolved by lump sum alimony, can be finalized. Under Mich. Comp. Laws § 552.9f, the waiting period is 60 days for cases without minor children and 180 days for cases with minor children. These periods run from the filing date and cannot be shortened for the child-involved cases. If the grounds for divorce arose outside Michigan, the filing spouse needs a full year of Michigan residency. A narrow exception to the 10-day county rule exists when a foreign-national spouse poses a risk of removing a minor child from the United States. Because residency is jurisdictional, filing before meeting the 180-day threshold results in dismissal, so confirm your dates before submitting paperwork.
When Lump Sum Alimony Makes Sense
Lump sum alimony in Michigan works best when the payer has liquid assets, when one spouse distrusts the other's reliability, or when both want a clean financial break. A one time alimony payment eliminates the risk that future job loss, bankruptcy, or death will interrupt support, and it ends all financial entanglement under Mich. Comp. Laws § 552.23.
Several situations favor a buyout alimony agreement over monthly payments. A recipient who fears the payer will stop paying, hide income, or file for bankruptcy gains security from receiving the full amount upfront, because true support generally is not dischargeable in bankruptcy. A payer with substantial assets but unpredictable income may prefer to settle the obligation once rather than commit to years of monthly payments. Couples who simply want no ongoing contact also benefit from finality. However, lump sum alimony carries real risks. The payer surrenders a large sum immediately and cannot recover it if circumstances change. The recipient gives up potential future increases and must manage a large amount responsibly. Because the structure is non-modifiable, both spouses should model best-case and worst-case scenarios before agreeing, ideally with attorney and financial-planner input.
