Same-facts estimate

Compare estimated support with one scenario

Use the same income and marriage facts to see how the planning estimate changes between Montana and Texas. This is educational, not a court prediction.

Montana

Conservative educational estimate based on statutory eligibility, reasonable need, ability to pay, income disparity, marriage length, marital standard of living, property division, earning capacity, education or training needs, age, health, and Montana statutory factors; no mandatory statewide formula applies.

Lower

$1,400/mo

Planning range: $910-$1,890/mo

Duration: Medium to long marriage

Montana relies heavily on court discretion or limited eligibility rules, so this estimate should be treated as a broad planning range.

Texas

Conservative educational estimate based on minimum reasonable need and ability to pay, capped at the lesser of $5,000 per month or 20% of payer gross monthly income.

Moderate

$680/mo

Planning range: $544-$816/mo

Duration: 10 to under 20 years

Key Differences

Calculation

Montana: Conservative educational estimate based on statutory eligibility, reasonable need, ability to pay, income disparity, marriage length, marital standard of living, property division, earning capacity, education or training needs, age, health, and Montana statutory 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

Montana: Montana has no fixed statutory duration formula. Maintenance may be temporary during the case, rehabilitative or transitional for a defined period, or longer-term where need, age, health, disability, long-term dependency, or limited earning capacity justify it. Duration depends on reasonable need, ability to pay, time needed for education or training, marriage length, property division, and the court's equitable judgment. 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

Montana: Montana maintenance may be modified under Mont. Code Ann. § 40-4-208 when statutory modification standards are met. Courts review changed circumstances affecting need, resources, employment, health, 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.

State Profiles

Montana

Montana uses the term maintenance and requires threshold findings before support may be awarded. A spouse must lack sufficient property to provide for reasonable needs and be unable to support themselves through appropriate employment, unless custodial circumstances make outside employment inappropriate. Courts do not use a mandatory statewide formula.

Eligibility: A spouse may qualify only if they lack sufficient property to provide for reasonable needs and cannot support themselves through appropriate employment. A spouse may also qualify when they are custodian of a child whose condition or circumstances make outside employment inappropriate. After threshold eligibility, courts consider financial resources, training needs, standard of living, marriage length, age, health, and the payer's ability to meet personal needs while paying maintenance.

CalculatorLaws

Texas

Texas uses the term spousal maintenance for court-ordered post-divorce support and imposes some of the nation's strictest eligibility requirements. Unlike many states, support is not presumed based solely on income disparity, and a spouse must first satisfy statutory eligibility thresholds before a court considers amount and duration.

Eligibility: A spouse generally must lack sufficient property after divorce to provide for minimum reasonable needs and satisfy at least one statutory ground. Common grounds include a marriage lasting 10 years or more combined with inability to earn sufficient income, a disabling condition, caregiving responsibilities for a disabled child, or recent family violence by the other spouse. The spouse seeking maintenance bears the burden of proving eligibility.
