Alimony in Kentucky.
Whether the state sets a formula or leaves it to the judge, what the court has to weigh, how long it runs, and what brings it to an end.

No formula, cap or presumptive amount for maintenance. The contrast within KRS 403.160 itself is exact and worth quoting: for temporary CHILD support the court must, under KRS 403.160(2)(a), 'within fourteen (14) days from the filing of said motion, order an amount of temporary child support based upon the child support guidelines as provided by law'; for temporary MAINTENANCE, KRS 403.160(5) supplies only 'in amounts and on terms just and proper in the circumstances'. Kentucky's child support guidelines are statutory and presumptive (KRS 403.212). No statewide court rule or Administrative Office of the Courts guideline producing a maintenance number was found.
Use the state’s own words
Kentucky calls it maintenance. KRS 403.200 is captioned 'Maintenance — Court may grant order for either spouse'; KRS 403.160 governs 'temporary maintenance'. The word 'alimony' does not appear in the operative sections of KRS Chapter 403.. Using the state’s own term matters when you are searching for forms or reading an order — the words are not interchangeable across state lines, and some of them mean different things in different places.
The short version4 points · tap one to jump to it
- What the law actually says
- How long it lasts — No. 'The duration of the marriage' is factor (d); the order runs 'for such periods of time as the court deems just'.
- Does behavior matter? — Not provided for, and the omission is deliberate rather than accidental.
- When it ends, and when it can change — Retirement is not addressed.

How long it lasts
Duration
No. 'The duration of the marriage' is factor (d); the order runs 'for such periods of time as the court deems just'. No bracket, presumption or cap. KRS 403.200 is the 1970 Uniform Marriage and Divorce Act text, enacted by 1972 Ky. Acts ch. 182, sec. 10, and its history line records no amendment since.
Does behavior matter?
Marital misconduct
Not provided for, and the omission is deliberate rather than accidental. KRS 403.200 contains no fault factor and no fault bar. Kentucky's only ground for dissolution is irretrievable breakdown (KRS 403.170), and KRS 403.150(5) provides: 'Previously existing defenses to divorce and legal separation, including but not limited to condonation, connivance, collusion, recrimination, insanity, and lapse of time, are abolished.' The statute therefore neither requires nor permits marital fault as a maintenance criterion; it simply does not provide for it. That is not the same thing as an express bar of the Alaska or Montana kind, and the entry should not be read as one.
When it ends, and when it can change
What brings it to an end
KRS 403.250(2): 'Unless otherwise agreed in writing or expressly provided in the decree, the obligation to pay future maintenance is terminated upon the death of either party or the remarriage of the party receiving maintenance.' Kentucky has NO cohabitation-termination statute and no statutory definition of cohabitation. Retirement is not addressed. A temporary order has its own end point, KRS 403.160(6)(c): a temporary order or temporary injunction 'Terminates when the final decree is entered or when the petition for dissolution or legal separation is voluntarily dismissed.'
Changing it later
KRS 403.250(1): 'Except as otherwise provided in subsection (6) of KRS 403.180, the provisions of any decree respecting maintenance may be modified only upon a showing of changed circumstances so substantial and continuing as to make the terms unconscionable. The provisions as to property disposition may not be revoked or modified, unless the court finds the existence of conditions that justify the reopening of a judgment under the laws of this state.' Non-modifiable maintenance is expressly permitted, and the mechanism is KRS 403.180(6): 'Except for terms concerning the support, custody, or visitation of children, the decree may expressly preclude or limit modification of terms if the separation agreement so provides. Otherwise, terms of a separation agreement are automatically modified by modification of the decree.' KRS 403.180(2) also makes the parties' agreement binding on the court 'unless it finds, after considering the economic circumstances of the parties and any other relevant evidence produced by the parties, on their own motion or on request of the court, that the separation agreement is unconscionable.'
Worth knowing about Kentucky
Kentucky's modification threshold is not substantial change; it is unconscionability. KRS 403.250(1) requires changed circumstances 'so substantial and continuing as to make the terms unconscionable', a materially higher bar than the substantial-change standard used by most of the states in this batch, and the same word the statute uses to police separation agreements in KRS 403.180(2). Kentucky's maintenance section is also one of the few in this batch that has never been amended since enactment: the history line of KRS 403.200 reads in its entirety 'History: Created 1972 Ky. Acts ch. 182, sec. 10.'
The tax rule changed, and most guides still describe the old one
For a divorce or separation instrument executed after 31 December 2018, alimony is not deductible by the person paying it and not taxable to the person receiving it. The Tax Cuts and Jobs Act repealed the provisions that made it otherwise. For an instrument executed on or before that date the old treatment continues — deductible to the payer, taxable to the recipient — unless it is later modified and the modification expressly adopts the new rule.
This is not a detail. Under the old rule a higher-rate payer could transfer income to a lower-rate recipient and the two of them shared the saving. That saving no longer exists, which changes what a given number is worth to each side. New Hampshire wrote the point into its own statute: its 23 per cent figure assumes non-deductibility, and reverts to 30 per cent if the federal treatment is ever restored.
Alongside the federal rule, Kentucky’s own income tax follows the federal treatment, so if you are a full-year Kentucky resident the federal answer above is the whole answer — no state adjustment either way. Kentucky fixes its Internal Revenue Code reference to a date rather than following federal changes automatically: 31 December 2024 for the 2025 tax year, moving to 31 December 2025 for tax years beginning on or after 1 January 2026. Both dates sit well after the 2017 Act, so the alimony rule above is picked up either way.
If you moved — and in a divorce somebody usually does — Kentucky is not a plain conformity state. For part-year residents and nonresidents filing Form 740-NP, the alimony deduction “cannot exceed Kentucky income,” and for full-year nonresidents it is “limited to the percentage of their Kentucky total income to their federal total income.” A payer with a grandfathered pre-2019 instrument and modest Kentucky-source income can therefore deduct far less in Kentucky than federally, or nothing at all. None of this appears in the statute, which never uses the word alimony, or in the resident Form 740 packet, which does not mention it either — it exists only in the 740-NP instructions. Four states do not conform their state income tax to it — Arkansas, California, New Jersey and New York — so this is worth knowing rather than assuming. The fifty-state table.
Source: Kentucky Department of Revenue, Form 740-NP instructions, Part I line 26 (“The alimony deduction cannot exceed Kentucky income”) and line 6; KRS 141.010(21) for the conformity date for tax years beginning on or after 1 January 2026; the 2025 Form 740 packet for the 31 December 2024 date applicable to 2025. Note that KRS 141.010(21) is overwritten rather than layered, so the statute as published today speaks only to 2026 and later. the state source Checked 15 Sep 2026.
