Florida Durational Alimony: Caps, Modification, and the 2023 Reform

Durational Alimony Replaced Permanent Alimony

Florida's 2023 alimony reform (Senate Bill 1416, effective July 1, 2023) eliminated permanent alimony entirely. Durational alimony is now the longest form of support the court can award, and it comes with hard statutory caps that did not exist before.

If you filed for divorce before July 1, 2023, the old rules (including permanent alimony) may still apply to your case. For petitions filed on or after July 1, 2023, durational alimony is the longest form of support available under the current statute.

How the Duration Caps Work

The maximum length of a durational alimony award depends on how long the marriage lasted, measured from the wedding date to the date the dissolution petition was filed.

A 14-year marriage (moderate-term) caps durational alimony at 8.4 years. A 22-year marriage (long-term) caps at 16.5 years. These are maximums — judges routinely award less based on the specific circumstances.

Marriages under 3 years are ineligible for durational alimony entirely. Bridge-the-gap alimony (capped at 2 years) and temporary alimony may be available, while rehabilitative alimony depends on a specific defined plan and the statutory need-and-ability analysis.

The 35% Income-Gap Formula

The amount of durational alimony is subject to a hard cap: the lesser of the recipient's documented reasonable need or 35% of the difference between the spouses' net incomes.

If the higher-earning spouse nets $8,500/month and the lower-earning spouse nets $3,000, the income gap is $5,500. The maximum monthly award is $1,925 (35% of $5,500), regardless of how high the recipient's documented expenses are.

This 35% ceiling applies to the durational alimony award itself. Other forms may be awarded only if their separate statutory requirements are met.

When Durational Alimony Can Be Modified

Unlike bridge-the-gap alimony (which cannot be modified once awarded), durational alimony can be changed if either party demonstrates a substantial, material, and permanent change in circumstances. Common triggers:

• Job loss or disability — involuntary, not a strategic resignation to reduce income (courts watch for this)
• Significant income increase for the recipient — if they land a much higher-paying job, the payer can petition to reduce
• Cohabitation — if the recipient enters a "supportive relationship" as defined by the statute (sharing finances, living together, holding out as a couple), the payer can seek reduction or termination
• Remarriage of the recipient — terminates durational alimony automatically by operation of law

The duration itself generally cannot be modified; an extension is available only in exceptional circumstances under the statute's clear-and-convincing standard.

Retirement Termination

The 2023 reform added a retirement-modification path: when the paying spouse reaches normal retirement age as defined by the Social Security Administration (currently 67 for anyone born in 1960 or later), they may petition for a reduction or termination of durational alimony.

Reaching the age alone is not enough. The paying spouse must show demonstrable and measurable efforts or actual retirement and that retirement reduces or will reduce the ability to pay; the obligor bears the burden of proving that reduced ability to pay.

This was one of the most significant changes from the old law, which had no automatic retirement trigger and forced paying spouses to litigate modification well into their retirement years.

How Durational Alimony Interacts with Property Division

Florida courts are prohibited from "double dipping" — using the same asset for both equitable distribution and alimony. The Florida Supreme Court established this principle in Diffenderfer v. Diffenderfer: if a pension or retirement account is divided as a marital asset, the monthly pension payments from that same account should not also be counted as the paying spouse's income when calculating alimony.

This matters practically because a spouse with a large retirement account that gets split in the property division may show a lower income stream than their pre-split earnings would suggest. Negotiating the tradeoff between a larger property share and a lower alimony obligation (or vice versa) is one of the most consequential decisions in a Florida divorce settlement.

The Florida Divorce Financial Split Guide includes a tax-adjusted comparison worksheet that models these tradeoffs — showing the real after-tax value of different property-division-versus-alimony scenarios side by side.
