After 25 years of marriage, you are generally entitled to a substantial share of everything the partnership built: the house, retirement accounts, investments, and other assets accumulated during the marriage. You may also qualify for long-term or indefinite spousal support, Social Security benefits worth up to 50% of your ex-spouse’s retirement benefit, and continued health coverage under your spouse’s employer plan for up to 36 months. Courts treat a marriage this long as a true economic joint venture, which pushes outcomes closer to an even split than they would be in a shorter marriage.
Your Share of the Marital Property
Every state separates marital property from separate property. Marital property covers almost everything either spouse earned or acquired during the marriage: the home, cars, bank accounts, investments, business interests, and household furnishings. Separate property is what you brought into the marriage, plus inheritances or gifts received by one spouse individually. After 25 years, most of what you own together is marital, because decades of shared finances leave very little untouched.
Nine states follow community property rules, in which marital assets and earnings are owned equally and divided 50/50.1Internal Revenue Service. Publication 555 (12/2024), Community Property The other 41 states and the District of Columbia use equitable distribution, which aims for a fair division rather than an automatically equal one. Judges there weigh each spouse’s income and earning capacity, health, age, and non-financial contributions like homemaking and child-rearing.
In practice, the gap between “equitable” and “equal” narrows a lot in a long marriage. Courts tend to view 25-year marriages as partnerships where both spouses contributed in different but comparable ways, so the division often lands close to 50/50 even in equitable distribution states. A judge is more likely to deviate noticeably when one spouse hid money, dissipated assets, or ran up reckless debt.
What Happens to Separate Property You Thought Was Yours
Separate property can lose its protected status through commingling. An inheritance deposited into a joint account used for household expenses is nearly impossible to trace back to its source after years of mingled deposits and withdrawals. Courts generally hold that separate property keeps its character only as long as you can trace it, and after two decades of shared finances the tracing exercise is often hopeless. The property then gets treated as marital.
The same pattern applies to a home one spouse owned before the marriage. If both spouses paid the mortgage, funded renovations, or refinanced jointly over the years, the non-owner spouse has a strong claim at least to the appreciation that occurred during the marriage.
The Family Home
The house is usually the single largest asset, and it generates the most conflict. There are three common paths. You sell and split the proceeds. One spouse buys the other out, usually by refinancing the mortgage alone or offsetting the value against other assets like retirement accounts. Or you agree to a deferred sale and co-own temporarily, often until children finish school or the market shifts.
A buyout only works if the spouse keeping the home can qualify for a mortgage on their own income, which can be a real hurdle for someone who was out of the workforce. A deferred sale avoids a bad-timing sale but requires ex-spouses to cooperate as co-owners, which does not always hold up.
Timing matters for taxes. Federal law lets you exclude up to $250,000 of capital gains on a primary residence as a single filer, or $500,000 if you sell while still legally married and file jointly. After 25 years, appreciation is often substantial, so selling before the divorce finalizes can preserve the larger exclusion. If one spouse moves out but the decree grants the other use of the home, the departed spouse is still treated as using the property as a principal residence for purposes of this exclusion.2Office of the Law Revision Counsel. 26 U.S. Code 121 – Exclusion of Gain From Sale of Principal Residence
Spousal Support After a Long Marriage
Spousal support exists to address the income gap a long marriage often creates. One spouse may have spent years managing the household while the other built a career and a salary. Courts look at that disparity directly, and the length of the marriage is one of the strongest factors in both the amount and the duration of support.
A 25-year marriage is well past the “long-term” threshold most states set, which usually begins around 10 years. In long-term marriages, courts have broad discretion to award support for an extended or indefinite period, potentially lasting until the recipient reaches retirement age or demonstrates the ability to become self-supporting. There is no automatic duration formula the way there might be for a 5-year marriage, and judges evaluate case by case.
Factors they weigh include each spouse’s income and earning capacity, the standard of living during the marriage, the age and health of both parties, and whether one spouse sacrificed career opportunities. If you spent 20 years out of the workforce raising children, a court is not going to expect you to match your ex-spouse’s income overnight.
When Support Can End or Change
Spousal support automatically terminates in most states when the recipient remarries. Many states also allow the paying spouse to request a reduction or termination if the recipient begins cohabiting with a new partner, though the payer has to file a motion and prove the relationship meets the state’s definition of cohabitation. Support can also be modified when either spouse experiences a substantial change in circumstances, such as job loss, disability, or a major increase in the recipient’s income. The payer’s own remarriage does not end the obligation; new household expenses from a second marriage are not grounds to terminate.
Retirement Accounts After 25 Years
Retirement savings are often the second-largest asset after the home, and after 25 years of contributions and growth the balances can be significant. The portion of any retirement account accumulated during the marriage is marital property subject to division, regardless of whose name is on the account. If a 401(k) existed before the wedding, only the contributions and growth from the wedding date forward are divisible.
QDROs for 401(k)s and Pensions
Dividing an employer-sponsored plan like a 401(k) or pension requires a Qualified Domestic Relations Order. A QDRO is a court order that directs the plan administrator to pay a portion of the account to the non-employee spouse, called the alternate payee. Without a valid QDRO, the plan can only pay benefits according to its own terms, no matter what the divorce decree says.3U.S. Department of Labor. Qualified Domestic Relations Orders Under ERISA: A Practical Guide to Dividing Retirement Benefits
A QDRO also exempts the distribution from the 10% early withdrawal penalty that would otherwise apply to anyone under 59½.4Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts You can roll your share into your own IRA or retirement account and keep its tax-deferred status, or take a cash distribution and pay ordinary income tax on it without the extra penalty.5Internal Revenue Service. Retirement Topics – QDRO: Qualified Domestic Relations Order Rolling it over is almost always the smarter long-term move.
If your ex-spouse has a traditional pension, the QDRO can also preserve your right to survivor benefits by treating you as the surviving spouse for purposes of a joint and survivor annuity.6Internal Revenue Service. Retirement Topics – Qualified Joint and Survivor Annuity This needs to be negotiated specifically. If the QDRO is silent on it, the participant can change the beneficiary later and you lose the claim.
IRAs do not require a QDRO. The settlement specifies the split and funds move directly between accounts. As long as the transfer is documented in the decree, it happens tax-free.
Social Security on Your Ex-Spouse’s Record
A 25-year marriage easily clears the 10-year threshold required to claim Social Security retirement benefits on your ex-spouse’s work record. To qualify, you must be at least 62 and currently unmarried.7Social Security Administration. Code of Federal Regulations 404.331 – Who Is Entitled to Wife’s or Husband’s Benefits as a Divorced Spouse
The maximum divorced spouse benefit is 50% of your ex-spouse’s full retirement benefit, reduced if you claim before your own full retirement age.8Social Security Administration. Benefits for Spouses The Social Security Administration pays you whichever is higher: your own earned benefit or the divorced spouse benefit. You do not receive both.
Claiming on your ex’s record has no effect on their benefits. Their monthly check stays the same, and benefits for their current spouse are also unaffected. The SSA does not notify your ex that you filed.
If your former spouse dies, you may qualify for survivor benefits as a divorced surviving spouse, provided the marriage lasted at least 10 years. Survivor benefits are more generous than spousal benefits and range from 71.5% to 100% of the deceased’s benefit, depending on when you claim.9Social Security Administration. What You Should Know About Social Security if Your Spouse Passes Away You can start reduced survivor benefits at 60, compared to 62 for regular divorced spouse benefits.
Health Insurance Coverage
If you have been covered under your spouse’s employer health plan, divorce is a qualifying event under COBRA that lets you continue the same coverage for up to 36 months.10U. S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers The cost is the full premium plus a 2% administrative fee, with no employer subsidy, which can be a sharp increase.
Losing spousal coverage also opens a 60-day special enrollment period to buy a plan through the federal or state health insurance marketplace.11HealthCare.gov. Special Enrollment Period (SEP) – Glossary Depending on your post-divorce income, premium subsidies may make a marketplace plan significantly cheaper than COBRA. Compare both before committing. COBRA keeps your current doctors and network; a marketplace plan may offer lower out-of-pocket costs.
What Happens to Joint Debt
Debt follows the same framework as property. Mortgages, car loans, credit cards, and other obligations incurred during the marriage are marital liabilities. Community property states presume debts are shared equally. Equitable distribution states divide them based on who incurred the debt, whether it benefited the household, and each person’s ability to repay.
Here is the part that catches people off guard: a divorce decree does not bind your creditors. If a joint credit card is assigned to your ex-spouse in the decree and your ex stops paying, the credit card company can still come after you. The creditor was not a party to the divorce and is not bound by its terms. Your remedy is to go back to court against your ex, which takes time and money while your credit score takes the hit. Experienced divorce attorneys push to close joint accounts and refinance joint debts into individual names before the divorce is finalized rather than relying on the decree to sort it out later.
Tax Consequences to Plan For
Divorce triggers several tax changes that affect your finances immediately and for years afterward.
For any divorce or separation agreement finalized after December 31, 2018, the paying spouse cannot deduct alimony and the receiving spouse does not report it as income. If your divorce was finalized before 2019, the old rules still apply: the payer deducts the payments and the recipient reports them as income. Modifying a pre-2019 agreement can switch you to the new rules if the modification expressly says so.12Internal Revenue Service. Topic No. 452, Alimony and Separate Maintenance
Transferring property between spouses as part of a divorce settlement does not trigger capital gains tax. Federal law treats the transfer as a gift for tax purposes, so the receiving spouse takes over the original owner’s cost basis rather than getting a stepped-up basis at current market value. The transfer must occur within one year of the divorce or be related to the cessation of the marriage.13Office of the Law Revision Counsel. 26 USC 1041 – Transfers of Property Between Spouses or Incident to Divorce
The inherited cost basis matters later. If you receive the family home with a cost basis of $150,000 and later sell for $600,000, your gain is $450,000. As a single filer, only $250,000 is excluded, leaving $200,000 potentially subject to capital gains tax. Negotiating who keeps the home without accounting for that embedded tax liability is one of the most common and expensive mistakes in long-marriage divorces.
Your filing status for the whole tax year turns on whether you are married or divorced on December 31. If your divorce is finalized by year-end, you file as single or head of household for the full year, which changes your brackets and standard deduction.14Internal Revenue Service. Divorce or Separation May Have an Effect on Taxes If your divorce is close to finishing in late fall or December, the timing can have meaningful tax implications, and a tax professional is worth consulting before you sign.
