Same-facts estimate

Compare estimated support with one scenario

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

South Dakota

Conservative educational estimate based on need, ability to pay, income disparity, marriage length, earning capacity, post-divorce financial condition, age, health, marital standard of living, property division, and South Dakota equitable factors; no mandatory statewide formula applies.

Lower

$1,400/mo

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

Duration: Medium to long marriage

South Dakota 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

Key Differences

Calculation

South Dakota: Conservative educational estimate based on need, ability to pay, income disparity, marriage length, earning capacity, post-divorce financial condition, age, health, marital standard of living, property division, and South Dakota equitable 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

South Dakota: South Dakota has no fixed statutory duration formula. Temporary alimony may be awarded while the divorce is pending. Post-divorce alimony may be rehabilitative, restitutional, permanent, or another equitable form depending on the facts. Rehabilitative support may be time-limited and tied to education, training, or self-support. Permanent or longer-term support may be possible where age, disability, health, or long-term dependency prevents self-support, but it is not automatic. 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

South Dakota: South Dakota alimony may be modified when a substantial change in circumstances justifies review, depending on the award type and decree terms. Courts evaluate changes affecting need, income, earning capacity, 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

South Dakota

South Dakota authorizes alimony when a divorce is granted and permits the court to require one spouse to make a suitable allowance for the other's support. The state does not use a mandatory statewide formula. Courts rely on discretionary factors such as marriage length, earning capacity, financial condition, age, health, social standing, and fault-related responsibility for the breakup.

Eligibility: A spouse may qualify if the court finds support suitable after reviewing the parties' financial and personal circumstances. South Dakota courts consider marriage length, earning ability, property division, age, health, social standing, and fault or responsibility for the divorce. Eligibility depends on equity rather than a strict income threshold.

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.
