TL;DR: As of July 1, 2023, Florida has eliminated permanent alimony for any new divorce case. For a 10-year marriage, which is now classified as "moderate-term," the focus shifts entirely to durational alimony. The length of this alimony generally cannot exceed 60% of the length of the marriage. The final duration depends on statutory factors like need, ability to pay, and sacrifices made during the marriage.
Ten years used to be a pivotal milestone in Florida divorce law, the entry point into a gray area where permanent alimony became a possibility. That reality is gone. A 2023 legislative overhaul (SB 1416) eliminated permanent alimony for any dissolution case filed on or after July 1, 2023. A 10-year marriage now falls squarely into the "moderate-term" category. The fight is no longer about whether alimony is temporary or permanent. The fight is over the amount and exact length of durational alimony, a battle governed by new statutory caps and the same old evidence of need and ability to pay.

You have been reading about this for weeks. You already know the marriage is over. What you do not know is what your money looks like on the other side. Alimony duration is not a calculator problem, but the new law has certainly introduced more math. Courts still weigh the evidence, but their discretion is now constrained by hard caps tied to the length of the marriage. The type of alimony awarded still shapes the outcome, but the menu of options has changed for good.
How Florida Classifies Alimony After the 2023 Legal Changes
Florida law recognizes several types of alimony, but for any case filed after July 1, 2023, permanent alimony is off the table. The available forms each have their own purpose and duration rules. Bridge-the-gap alimony helps a spouse transition from married to single life and cannot exceed two years. Rehabilitative alimony funds a specific, written plan for education or training to achieve self-sufficiency, and it is limited to five years. Durational alimony is the primary tool for providing economic assistance after short-term, moderate-term, or long-term marriages under the new law.
The new law also redefined marriage length classifications. A short-term marriage is less than 10 years. A moderate-term marriage is 10 years or more but less than 20 years. A long-term marriage is 20 years or more. A 10-year marriage sits at the front edge of the moderate-term category. For a moderate-term marriage, durational alimony generally may not be awarded for a term longer than 60% of the length of the marriage. For a marriage of exactly 10 years, that means a presumptive maximum of six years. The party seeking alimony still bears the burden of proving need and the other spouse's ability to pay.
The type of alimony awarded controls the duration. A ten-year marriage might result in a two-year rehabilitative plan if the requesting spouse has a credible, documented path to a new career. More commonly, it will result in durational alimony for a period of up to six years, with the exact length determined by the specific facts of the case.
What Courts Examine When Setting Durational Alimony
Florida Statutes § 61.08 sets out the factors courts must consider when determining alimony, and those factors remain critical under the new law. Courts examine the standard of living established during the marriage and the anticipated need of each party after the divorce, the duration of the marriage, the age and physical, mental, and emotional condition of each party, the financial resources of each party including marital and non-marital assets and liabilities, the earning capacities, educational levels, vocational skills, and employability of the parties, the contribution of each party to the marriage including homemaking and child care, the responsibilities each party will have for any minor children, and all sources of income available to either party.
For a 10-year marriage, the analysis often turns on sacrifices made and opportunities lost. Did one spouse leave the workforce to raise children? Did they bankroll the other's career at the expense of their own? A spouse who can prove those contributions has a stronger case for a longer duration, pushing toward the statutory cap. A spouse with marketable skills, a recent work history, or significant non-marital assets faces a steeper climb to justify a lengthy award. The court must first make a specific finding of actual need and the other party's ability to pay, then make written findings on the statutory factors. That is where the case is won or lost.
Durational alimony is not a reward or a punishment. It is a tool to address a proven need where equitable distribution is not enough to put the requesting spouse on a path to self-sufficiency. The burden stays on the requesting spouse to prove need and the paying spouse's ability to pay.
How Modification and Termination Work After Alimony Is Ordered
Once alimony is awarded, the amount is not always set in stone. Modification requires a showing of a substantial, material, permanent, and involuntary change in circumstances that was not contemplated at the time of the original judgment. That standard applies to durational alimony awarded under the new law and to pre-existing permanent alimony awards entered in older cases, which remain enforceable and modifiable under the law that governed them.
Alimony terminates automatically upon the death of either party or the remarriage of the recipient. It may also be reduced or terminated if the recipient is in a supportive relationship as defined by Florida Statutes § 61.14. That means proving the recipient is receiving support from someone else that reduces the recipient's need. The 2023 law also created a specific process for a paying spouse to seek modification or termination of an alimony obligation upon reaching normal retirement age, based on a set of factors the court must weigh. The burden is on the payor to prove those conditions have been met.
Durational alimony can be modified or terminated in amount based on a substantial change in circumstances. Its length may only be extended under exceptional circumstances, and only when the statutory requirements for an extension are met. Rehabilitative alimony can be modified or terminated if the plan is completed, is not being followed, or circumstances change substantially. Bridge-the-gap alimony is not modifiable in amount or duration. The type of alimony locked in at final judgment defines what can be changed later.
Why the Final Judgment Language Matters More Than the Statute
Courts have discretion within the statutory framework, and that discretion shows up in the final judgment. A judgment awarding durational alimony should specify the exact term and amount. A judgment that incorporates a settlement agreement may contain non-modifiable terms that override the general statutory default rules. These details are not boilerplate.
The final judgment is the governing document. Ambiguity is future litigation. A payor who agrees to an alimony term without addressing how retirement will be handled may face a tougher modification fight later. A recipient who accepts durational alimony without clarity on termination events can be blindsided. What you fight for, or hand over, during negotiation becomes the contract that governs your post-divorce financial life.
Modification litigation is expensive and hard, because courts do not enjoy reopening final judgments. The time to shape the duration and terms of alimony is before the judge signs the decree. Once that judgment is entered, the fight shifts from what is fair to what the document allows.

The duration of alimony after a 10-year marriage is now governed by new rules, new classifications, and hard statutory caps. Your outcome will be decided by the strategic choices made during your case and memorialized in a final judgment that has to anticipate what comes next. The difference between a three-year award and a six-year award is not semantics; it is years of your financial life. Courts apply the statutory factors, but those factors are filtered through the evidence, testimony, and legal arguments actually put in front of the judge.

Frequently Asked Questions
Does a 10-year marriage automatically qualify for permanent alimony in Florida?
No. As of July 1, 2023, permanent alimony has been eliminated in Florida for new dissolution of marriage petitions. A 10-year marriage is classified as a "moderate-term marriage," and the primary form of ongoing support available is durational alimony, which is capped and generally cannot last longer than 60% of the length of the marriage.
Can durational alimony awarded after a 10-year marriage be extended beyond six years?
Only in narrow circumstances. For a moderate-term marriage, the law caps durational alimony at 60% of the length of the marriage, which is six years for a 10-year marriage. A court may extend the term only upon a showing of exceptional circumstances under the statute, and the extension cannot exceed the length of the marriage itself. Do not plan around the exception.
What qualifies as a substantial change in circumstances for modifying alimony?
A substantial change must be material, permanent, involuntary, and not contemplated at the time of the original judgment. Examples include involuntary job loss, a long-term disability, or reaching normal retirement age under the retirement provisions of the statute. Voluntary career changes, elective reductions in income, or temporary financial setbacks typically do not meet that threshold.
How does a supportive relationship affect alimony in Florida?
Under Florida Statutes § 61.14, proof that the recipient is in a supportive relationship can justify reducing or terminating alimony. Courts examine factors such as the extent to which the parties hold themselves out as a couple, the length of time they have lived together, financial interdependence, shared property, and support provided between them. The burden of proof is on the paying spouse to establish the relationship and its financial effect.
