How Durational Alimony Works in Florida: Length, Caps, and Endings

Durational alimony in Florida is spousal support paid for a fixed period after divorce, available only when the marriage lasted at least three years. The length of payments is capped as a percentage of the marriage’s duration, and the monthly amount cannot exceed the recipient’s reasonable need or 35 percent of the difference between the spouses’ net incomes, whichever is lower. Since the 2023 alimony reform ended permanent alimony, durational alimony is now the longest-running form of support a Florida court can order.

Who Qualifies

Two threshold rules decide whether durational alimony is even on the table.

First, the marriage must have lasted at least three years. Florida measures length from the wedding date to the date the petition for dissolution is filed, not the date the divorce becomes final.¹ A long separation before someone files does not add to the count. If the marriage falls short of three years, the court cannot award durational alimony at all.²

Second, the requesting spouse must show a genuine financial need, and the other spouse must have the ability to pay. The court has to put both findings in writing in the order.² Sworn financial affidavits, tax returns, and bank statements carry the weight here.

Once those thresholds are met, the marriage falls into one of three tiers that drive the duration cap:

Short-term: less than 10 years
Moderate-term: 10 years up to 20 years
Long-term: 20 years or more

These tiers are rebuttable presumptions, so a judge can reclassify a marriage in unusual circumstances, but they are the default framework for every case.¹

How Long Durational Alimony Can Last

The maximum length of payments is tied to the marriage tier:

Short-term marriage: up to 50 percent of the marriage’s length
Moderate-term marriage: up to 60 percent of the marriage’s length
Long-term marriage: up to 75 percent of the marriage’s length

No award can exceed the total length of the marriage itself.² An eight-year marriage caps at four years of payments. A 15-year marriage caps at nine years. A 25-year marriage caps at 18 years and nine months. These numbers are ceilings. Judges can and do set shorter terms when the circumstances call for it.

How Much the Payments Can Be

The dollar amount has its own hard cap. The award cannot exceed:

the recipient’s reasonable need, or
35 percent of the difference between the two spouses’ net incomes,

whichever figure is smaller.²

Net income for this calculation follows the formula in Florida Statute 61.30, which subtracts taxes, mandatory deductions, and individual health insurance premiums from gross income. Spousal support already being paid under a court order in the same case is excluded from the net income figures.²

There is also a fairness guardrail. The award cannot leave the paying spouse with significantly less net income than the recipient, unless the court makes written findings of exceptional circumstances.²

What the Judge Weighs Inside Those Caps

The caps are the outer limits. Within them, the court looks at eight statutory factors to decide the actual form, amount, and duration of alimony:

Marriage duration
Standard of living established during the marriage and each spouse’s anticipated needs
Age and the physical, mental, and emotional condition of each spouse, including any disability
Income and resources, including earnings from marital and non-marital assets
Earning capacity, education, vocational skills, and realistic ability to become self-supporting
Contributions to the marriage, including homemaking, child care, and supporting the other spouse’s career or education
Parenting responsibilities, with special weight for caring for a child with a disability
Any other factor necessary for fairness, which must be specifically identified in writing

Adultery

Florida courts can factor in either spouse’s adultery and its economic impact on the marriage.³ The operative words are “economic impact.” A spouse who spent significant marital funds on an affair gives the court a measurable financial harm to work with. Adultery without a dollar consequence carries far less weight.

When a Court Can Extend Beyond the Cap

In narrow situations, a judge can extend durational alimony past the percentage cap. The recipient has to prove the need by clear and convincing evidence, a higher bar than the usual standard. The court weighs four specific factors:

Whether the recipient’s age and job prospects limit their ability to become self-supporting
Whether the recipient’s financial resources are too limited for self-support
Whether the recipient has a physical or mental disability that prevents self-support
Whether the recipient is the primary caregiver for a disabled child common to both parties

If an extension rests on caregiving for a disabled child, it ends when the child no longer needs that level of care or upon the child’s death, unless one of the other factors independently justifies continuing support.²

When Payments End or Change

Automatic Termination

Durational alimony ends automatically when either former spouse dies or the recipient remarries. No court order or motion is required for those events to cut off the obligation.²

Modifying the Monthly Amount

Either party can petition to raise or lower the payment amount based on a substantial, permanent, and involuntary change in financial circumstances. A layoff, a serious illness, or a significant and unexpected jump in the recipient’s income can all qualify. The process starts with a supplemental petition and evidence showing the financial picture has genuinely shifted since the original order.

Modifying the Length

Changing the duration is much harder. The statute says the length of durational alimony cannot be modified except under exceptional circumstances, and the same four factors that justify extensions beyond the cap apply, under the same clear and convincing evidence standard.²

Supportive Relationships

If the recipient begins living with a new partner in a relationship that resembles a marriage, the payor can petition to reduce or terminate alimony. The payor must first prove the supportive relationship exists by a preponderance of the evidence. If that burden is met, it shifts to the recipient to show why alimony should continue anyway.⁴

Courts look at a wide range of indicators: whether the couple uses the same last name or mailing address, whether they pool finances or hold joint accounts, whether one supports the other, whether they have bought property together, and whether they care for each other’s children. The relationship must have existed within the 365 days before the petition.⁴

Retirement

Retirement can support a modification, and the statute lists “reasonable retirement” as a factor the court may consider.² Retiring does not automatically end payments. The payor must show that retirement is a substantial change in circumstances, and the court weighs whether the chosen retirement age is reasonable given the payor’s occupation, health, and the age at which others in similar careers typically retire. Florida courts generally treat 65 as reasonable. Retiring significantly earlier may not justify a reduction when the payor is healthy and able to keep working.

Enforcement and Securing the Award

Income Deduction

When a court enters a final durational alimony order, it must at the same time issue an income deduction order to the payor’s employer, withholding the support amount from wages automatically. If the payor falls behind, the order adds at least 20 percent on top of the regular payment until the arrearage is cleared. Attorney’s fees and court costs owed under the order can also be deducted, but only after the arrearage itself is satisfied.⁵

Contempt

For willful non-payment, the recipient can file a motion for contempt. Before imposing civil contempt, the court must find the payor has the ability to pay and is choosing not to. A judge may order payment of the arrearage by a specific date or face jail. Civil contempt sentences are typically indefinite, meaning the payor can end the jail time by paying the specified amount. If pursued criminally, the penalty can reach up to six months of incarceration.

Life Insurance or Bond

Because durational alimony ends when the payor dies, the recipient can lose the income entirely without protection in place. A court can order the paying spouse to buy or maintain life insurance, a bond, or other security to cover the award, but only after making specific written findings that special circumstances justify it. The cost can be split between the parties based on each one’s ability to pay.² If alimony is a meaningful part of the recipient’s budget, raising this during the divorce proceedings is worth the effort.

Federal Tax Treatment

For any divorce finalized after December 31, 2018, alimony payments are not deductible by the payor and not taxable to the recipient. The Tax Cuts and Jobs Act permanently repealed the federal tax code sections that previously allowed the deduction and required inclusion in income.⁶ Unlike many TCJA provisions set to sunset after 2025, this one is permanent.

The practical result: payors send alimony out of after-tax dollars with no deduction, and recipients keep the full amount without federal income tax. The old settlement math, where a high-bracket payor could shift income to a lower-bracket recipient and both came out ahead, no longer works. Both sides should price that into any negotiation.
