Legal frameworkTemporary maintenance may be awarded during the divorce case to address immediate financial needs. Final maintenance is governed by KRS § 403.200, which requires statutory eligibility findings before the court sets an amount and duration it deems just.Temporary maintenance during divorce proceedings is calculated using statutory formulas established in Domestic Relations Law § 236(B)(5-a). Post-divorce maintenance is governed by § 236(B)(6), where courts apply statutory formulas, duration advisory ranges, and deviation factors before entering a final award.

Same-facts estimate

Compare estimated support with one scenario

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

Kentucky

Conservative educational estimate based on statutory eligibility, reasonable need, ability to pay, income disparity, marriage length, financial resources, earning capacity, standard of living, age, health, and Kentucky statutory factors; no mandatory statewide formula applies.

Lower

$1,467/mo

Planning range: $954-$1,980/mo

Duration: Medium to long marriage

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

New York

Guideline maintenance estimate using New York's higher formula: 30% of payer income minus 20% of recipient income, capped so the recipient does not receive more than 40% of combined income after maintenance. If the maintenance payer is also the noncustodial parent paying child support, New York uses a lower formula: 20% of payer income minus 25% of recipient income.

Moderate

$2,000/mo

Planning range: $1,600-$2,400/mo

Duration: About 3 years

Key Differences

Calculation

Kentucky: Conservative educational estimate based on statutory eligibility, reasonable need, ability to pay, income disparity, marriage length, financial resources, earning capacity, standard of living, age, health, and Kentucky statutory factors; no mandatory statewide formula applies. New York: New York uses statutory guideline formulas for temporary and post-divorce maintenance on the payor's income up to the statutory income cap. The formulas are presumptive guideline calculations, but courts may adjust or deviate if the guideline amount is unjust or inappropriate after considering statutory factors. Maintenance above the income cap is discretionary.

Duration

Kentucky: Kentucky has no fixed statutory duration formula. Maintenance may be temporary during the case, rehabilitative for a defined period tied to education, training, or employment, or longer-term in appropriate cases involving long marriages, age, health limitations, or limited earning capacity. Duration depends on reasonable need, ability to pay, marriage length, self-support prospects, property division, and the court's equitable judgment. New York: New York uses a nonmandatory advisory duration schedule for post-divorce maintenance. For marriages up to and including 15 years, guideline duration is generally 15% to 30% of the marriage length. For marriages over 15 years and up to 20 years, guideline duration is generally 30% to 40% of the marriage length. For marriages over 20 years, guideline duration is generally 35% to 50% of the marriage length. Temporary maintenance lasts only while the divorce case is pending.

Modification

Kentucky: Maintenance may be modified under KRS § 403.250 upon changed circumstances so substantial and continuing as to make the existing terms unconscionable. Agreements may restrict modification if validly incorporated into the decree. New York: Maintenance orders may be modified when statutory standards for modification are satisfied, including qualifying changes in circumstances. Separation agreements and judgments may contain additional provisions affecting modification rights.

State Profiles

Kentucky

Kentucky uses the term maintenance and requires threshold findings before a court may award support. Under KRS § 403.200, the requesting spouse must lack sufficient property to provide for reasonable needs and be unable to support themselves through appropriate employment, with special consideration for custodial circumstances. Courts do not use a mandatory formula for amount or duration.

Eligibility: A spouse may qualify only if the court finds that the spouse lacks sufficient property, including marital property apportioned in the divorce, to provide for reasonable needs. The court must also find that the spouse cannot support themselves through appropriate employment or is custodian of a child whose condition or circumstances make outside employment inappropriate. Income disparity alone is not enough without the statutory findings.

New York

New York uses the term maintenance for spousal support and employs statutory formulas that provide presumptive maintenance amounts in many cases. Courts begin with the statutory calculation but may deviate when the formula would be unjust or inappropriate after considering statutory factors. Maintenance awards are intended to address economic disparities created by the marriage and divorce.

Eligibility: A spouse may qualify for maintenance when there is a demonstrated economic disparity and the statutory analysis supports an award. Courts review the parties' incomes, property distribution, future earning potential, and financial circumstances. Qualification does not require fault and is evaluated under the statutory framework.
