Calculation
Michigan: Conservative educational estimate based on need, ability to pay, income disparity, marriage length, marital standard of living, earning capacity, property division, health, age, and Michigan spousal-support factors; no mandatory statewide formula applies. Texas: Texas is a strict limited-eligibility maintenance state. Court-ordered spousal maintenance is not automatic and is available only if the requesting spouse lacks sufficient property to meet minimum reasonable needs and satisfies a statutory eligibility ground. Texas has no formula for the actual award amount, but it has a hard statutory maximum of the lesser of $5,000 per month or 20% of payer gross monthly income.
Duration
Michigan: Michigan has no fixed statutory duration formula. The court may award support for a short rehabilitative period, a longer transition period, an indefinite period in appropriate long-marriage or disability cases, or no support. Duration depends on need, ability to pay, marriage length, earning capacity, age, health, property division, and equity. Support may terminate or be modified under the order, agreement, remarriage or cohabitation provisions if included, death, changed circumstances, or court order. Texas: Texas generally requires maintenance to last only for the shortest reasonable period that allows the recipient to earn enough income to meet minimum reasonable needs. Maximum duration is generally 5 years for family-violence eligibility cases or marriages of at least 10 but less than 20 years, 7 years for marriages of at least 20 but less than 30 years, and 10 years for marriages of 30 years or more. Maintenance based on the recipient's disability or care of a disabled child may continue as long as the qualifying condition continues, subject to review.
Modification
Michigan: Periodic alimony may generally be modified upon a substantial change in circumstances unless a judgment or agreement limits modification. Courts review changes affecting financial need, earning capacity, or ability to pay. Texas: A maintenance order may be modified upon a material and substantial change in circumstances affecting either party. Any modified award remains subject to Texas statutory caps and limitations.
