Divorce after 25 years of marriage uses the same court forms and the same filing steps as any other divorce. What changes is the size and complexity of what has to be resolved: more shared property, more retirement value, and, in some states, different rules for spousal support once a marriage crosses a certain length. This is sometimes called gray divorce, a description of who is divorcing, not a separate legal process.
Key Takeaway: There is no special "long marriage" petition. The filing process after 25 years of marriage is the same standard petition used for any divorce. What differs is scope: California treats a marriage of 10 years or more as presumptively long duration for spousal support jurisdiction purposes, while Florida's 2023 alimony reform defines long-term marriage as 20 years or more and caps durational alimony instead of allowing permanent alimony.
What's Different About Divorce After 25+ Years of Marriage?
The petition, response, and financial disclosure requirements are the same whether a marriage lasted one year or 25 years. What actually differs after a long marriage is the underlying financial picture: retirement accounts with decades of contributions, a family home with significant equity, pensions, and often two spouses whose earning capacities diverged a long time ago, sometimes because one spouse stepped back from a career to run the household or raise children.
None of that changes the forms filed. It changes how much work goes into identifying, valuing, and dividing what the marriage accumulated, and it is the reason spousal support and retirement division tend to matter more in a 25 year marriage than in a much shorter one.
How Does a Long Marriage Affect Alimony and Property Division?
Property division rules themselves do not change based on marriage length. California and Florida both divide property and debts acquired during the marriage under their own community or equitable distribution frameworks, regardless of whether the marriage lasted 5 years or 25.
Spousal support is where marriage length matters more directly. Both states treat longer marriages differently from shorter ones, though the specific mechanism differs between the two, covered separately below.
California: Spousal Support in a Marriage of Long Duration
Under California Family Code Section 4336, a marriage of 10 years or more, measured from the date of marriage to the date of separation, creates a presumption that it is a "marriage of long duration." A 25 year marriage clears that threshold by a wide margin.
What that presumption actually does is narrower than many people assume: it means the court retains ongoing jurisdiction to revisit spousal support in the future, unless the spouses agree in writing otherwise. It does not automatically award support, does not fix the amount, and does not set support to continue for life. Whether support is awarded at all, and in what amount, is still decided using the Family Code Section 4320 factors applied to the specific facts of the case. Our full guide, The California Spousal Support 10-Year Rule Explained, covers this distinction in detail, including how it differs for marriages under 10 years. General background on spousal support is also available from the California Courts Self-Help Center.
Florida: Alimony Reform and Long-Term Marriages
Florida alimony law changed significantly under a 2023 reform (SB 1416), effective July 1, 2023, which eliminated permanent alimony for new cases. Under the current version of Florida Statutes section 61.08, marriages are grouped into three categories: a short-term marriage of under 10 years, a moderate-term marriage of 10 to 20 years, and a long-term marriage of 20 years or more.
For a 25 year marriage, that means long-term status under current Florida law. Rather than permanent alimony, Florida now allows durational alimony, capped at a percentage of the marriage's length: up to 50 percent for a short-term marriage, 60 percent for a moderate-term marriage, and 75 percent for a long-term marriage. A judge still has to apply the statutory factors to decide whether alimony is awarded at all and in what amount; the durational cap limits how long it can last, not whether it happens.
Retirement, Social Security, and Long-Term-Marriage Divorce
Retirement accounts accumulated during a long marriage are typically community or marital property, subject to division the same way any other property is, through a Qualified Domestic Relations Order or similar mechanism for accounts like a 401(k) or pension. A 25 year marriage usually means significantly more retirement value has built up than in a short marriage, which makes accurately identifying and valuing every account a bigger part of the case. Our guide on dividing retirement accounts covers how that mechanism works.
Marriage length can also matter for certain federal Social Security rules tied to spousal or divorced-spouse benefits. Those rules are set and administered by the Social Security Administration, not by California or Florida courts, and specific eligibility requirements should be confirmed directly at ssa.gov rather than assumed from this guide.
Special Considerations for Gray Divorce
Gray divorce describes couples divorcing later in life, often in their 50s, 60s, or beyond, frequently after a marriage of 20, 25, or more years. It is a demographic description, not a separate court process. A few things tend to matter more in these cases:
- Less time to rebuild retirement savings after property division, compared to a couple divorcing decades earlier
- Health insurance transitions, since a spouse covered under the other's employer plan will generally need a new source of coverage
- Adult children's involvement, which does not change the legal process but often changes the emotional and logistical context of the case
Our guide, Gray Divorce in California, and High-Asset Divorce in California go into more detail on the property and planning issues that come up more often in these cases.
What About Divorce After a Very Short Marriage?
Some searches for this topic actually come from the opposite situation: a very short marriage, sometimes a matter of weeks or months. How to get a divorce after 1 month of marriage follows the same petition and filing process as any other divorce; there is no minimum marriage length required to file in California or Florida, only the standard residency requirements. A short marriage typically means less commingled property, no long-duration support presumption in either state, and, in some cases, eligibility for a faster uncontested or summary track if both spouses qualify and agree on the terms.
Common Mistakes to Avoid
- Assuming a 25 year marriage automatically means lifetime or permanent alimony in either state
- Treating California's "long duration" presumption as an automatic support award rather than a jurisdiction rule
- Assuming Florida still allows permanent alimony after the 2023 reform
- Overlooking retirement accounts, pensions, or Social Security-related questions that matter more after a long marriage
- Assuming a very short marriage requires different filing forms than a long one
Frequently Asked Questions
How do I divorce after 25 years of marriage?
The filing process itself is the same petition, response, and disclosure steps as any other divorce in your state. What differs at 25 years is the scope of what has to be untangled: more shared property, more retirement accounts, and, in California, a presumption that the marriage qualifies for long-term spousal support jurisdiction. The paperwork is standard; the underlying finances usually are not.
How does divorce after 25 years of marriage affect alimony?
A marriage this long generally qualifies as long-duration or long-term under both California and Florida law, which changes how spousal support is handled, not whether it is automatically awarded. In California, it affects whether the court keeps ongoing jurisdiction over support. In Florida, since the 2023 reform, it affects the durational cap on how long support can last.
Does how I got married, including a courthouse ceremony, change how to get divorce after a court marriage?
No. Whether a couple married in a religious ceremony, a courthouse civil ceremony, or any other legally recognized format, the divorce process afterward is identical. Courts do not treat a civil or courthouse marriage differently from any other legally valid marriage for filing, property division, or support.
How do you get a divorce after 1 month of marriage?
The same way you would after 25 years: file the standard petition for your state. How to get divorce after 1 month of marriage is procedurally no different, though a very short marriage usually means less commingled property, no long-duration support presumption, and, in some cases, eligibility for a simplified or summary process if both spouses qualify and agree.
What is gray divorce?
Gray divorce is a term for couples divorcing later in life, generally in their 50s or older, often after a long marriage. It is not a separate legal filing category. The term describes a demographic pattern, longer life expectancy and more couples divorcing after children are grown, not a distinct court process.
Does a marriage of 25 years or more mean automatic lifetime alimony?
No, in either California or Florida. In California, a long-duration marriage means the court keeps ongoing jurisdiction to revisit support, not that support is automatically awarded or permanent. In Florida, permanent alimony was eliminated for new cases starting July 1, 2023, and even a long-term marriage now has a durational cap on support.
Are retirement accounts divided differently after a long marriage?
The legal rules for dividing retirement accounts do not change based on marriage length, but a 25 year marriage typically means more retirement value accumulated during the marriage, which is generally community or marital property subject to division. See our guide on dividing retirement accounts for how that process works mechanically.
