After a 30-year marriage, what you are entitled to in a divorce typically includes a share of the marital assets and debts, alimony that often runs indefinitely, a portion of your spouse’s retirement accounts, Social Security benefits based on your ex’s earnings record, and — in many cases — continued access to health coverage through COBRA, the marketplace, or Medicare on your ex-spouse’s work history. The exact split depends on your state’s rules and the specifics of your finances, but the length of the marriage itself pushes almost every factor in the direction of a more even, longer-lasting division.
Your Share of the Marital Property
Where you live sets the starting point. A handful of states follow community property rules, which begin from the assumption that everything earned or acquired during the marriage is split equally. Most states use equitable distribution, where a judge weighs each spouse’s contributions, earning capacity, health, and financial needs to reach a division that is fair but not necessarily 50/50. In a marriage this long, the length of the relationship itself pulls equitable distribution closer to an even split, because both spouses are presumed to have contributed substantially over three decades.
The pool of what’s on the table is usually much larger than bank accounts and a house. Brokerage accounts, rental properties, stock options, deferred compensation, and business interests all have to be identified, valued, and divided. Courts routinely require professional appraisals for real estate, and when either spouse owns a business, a formal business valuation is almost always necessary. These valuations can run from a few thousand dollars into the tens of thousands when forensic accounting is involved.
Property transfers between spouses as part of the divorce are generally not taxable events. The tax code treats them as gifts, and the receiving spouse takes the same tax basis the transferring spouse had.1Office of the Law Revision Counsel. 26 USC 1041 – Transfers of Property Between Spouses or Incident to Divorce That basis matters later. Two assets that look equal on paper can produce very different after-tax values. A $400,000 brokerage account with a $100,000 basis is worth less in practice than $400,000 in cash, because selling those investments triggers taxes on $300,000 of gains. When you weigh what you are “entitled” to, weigh it after tax.
What Happens to the House
For most couples married 30 years, the family home is the single most significant asset and the one with the most exposure to capital gains tax. If you sell while still married and file jointly, you can exclude up to $500,000 of capital gains from your income, provided both spouses lived in the home for at least two of the five years before the sale.2Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Once the divorce is final, each ex-spouse filing individually can exclude only $250,000.
On a house bought decades ago, appreciation can easily blow past $250,000, which makes timing part of what you’re negotiating. If the decree awards the home to one spouse while the other moves out, the departing spouse can still treat the home as their principal residence for the exclusion, as long as the other spouse is living there under the terms of the divorce agreement and the departing spouse retains an ownership interest.2Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Without that provision, the spouse who moved out could lose the exclusion entirely.
Coordinating the sale before the divorce is finalized preserves the full joint $500,000 exclusion. When that isn’t realistic, the divorce agreement should explicitly cover the sale timeline and how gains will be split, with both spouses’ tax positions accounted for.
Alimony You Can Expect After a Long Marriage
A 30-year marriage almost always puts alimony on the table. Courts view decades of financial interdependence as creating a legitimate expectation that both spouses will maintain a roughly comparable standard of living after the split. Judges weigh each spouse’s age, health, income, earning capacity, and the role each played during the marriage. If one spouse left the workforce to raise children or support the other’s career, that sacrifice weighs heavily in their favor.
Duration is where long marriages stand apart. In shorter marriages, alimony is often limited to a transitional period. After 30 years, many courts award indefinite or permanent support, particularly when the receiving spouse is in their 50s or 60s and has limited ability to re-enter the workforce at a competitive level. Some states use formulas that tie alimony duration to the length of the marriage, but for marriages this long the practical result is often open-ended support.
How Alimony Is Taxed
For divorces finalized after December 31, 2018, the paying spouse cannot deduct alimony, and the receiving spouse does not include it in taxable income.3Internal Revenue Service. Publication 504 – Divorced or Separated Individuals This is the opposite of how alimony worked for decades, and it changes the negotiation math. Before 2019, a higher-earning spouse could deduct payments at their top marginal rate. Now the payer bears the full cost, and a dollar of alimony costs the payer a full dollar with no tax offset.4Internal Revenue Service. Divorce or Separation May Have an Effect on Taxes If you’re the receiving spouse, the number in the agreement is the number you actually get to keep.
Life Insurance to Back the Alimony
When alimony is expected to last a decade or more, courts frequently require the paying spouse to maintain a life insurance policy naming the receiving spouse as beneficiary. The death benefit protects the alimony stream if the payer dies before the obligation ends. The coverage amount is typically set to approximate the remaining alimony value, and it may decrease over time as the obligation shrinks. Alimony that depends on one person’s continued existence is fragile without it, so if the agreement doesn’t address life insurance, negotiate it in.
Building In a Cost-of-Living Adjustment
Alimony set at a fixed amount in your 50s can lose real purchasing power by the time you’re 70. A cost-of-living adjustment clause tied to an inflation index avoids the need to go back to court for a modification every few years. Building in an automatic adjustment now is far cheaper than litigating a modification later.
Your Share of Retirement Accounts
After 30 years, retirement accounts are often the largest marital asset after the home, and you are generally entitled to the portion accumulated during the marriage. How you actually receive it depends on the type of account.
401(k)s, 403(b)s, and Pensions
Employer-sponsored plans governed by federal law can only be divided through a Qualified Domestic Relations Order. A QDRO is a specific court order that directs the plan administrator to pay a portion of the participant’s benefits to the other spouse, called the alternate payee.5U.S. Department of Labor. Qualified Domestic Relations Orders Under ERISA – A Practical Guide to Dividing Retirement Benefits Without a valid QDRO, the plan administrator must follow the plan’s own terms and pay benefits only to the participant, regardless of what the divorce decree says.
The alternate payee reports QDRO distributions as their own income.6Internal Revenue Service. Retirement Topics – QDRO Qualified Domestic Relations Order A significant advantage: distributions from a qualified plan to an alternate payee under a QDRO are exempt from the 10% early withdrawal penalty, even if the recipient is under 59½.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions The alternate payee can also roll the distribution into their own IRA or qualified plan to defer taxes entirely.
IRAs
Traditional and Roth IRAs don’t use QDROs. Transfers between spouses incident to divorce are handled through a transfer specified in the divorce decree or a direct trustee-to-trustee transfer. The important catch: the penalty exception that applies to QDRO distributions does not apply to IRAs.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions If you receive IRA funds in a divorce and withdraw them before 59½, you’ll owe the 10% penalty on top of income tax unless another exception applies.
Valuing a Pension
A pension’s worth is not just a number on a statement. Its value depends on the monthly benefit, the pensioner’s life expectancy, cost-of-living adjustments, and survivor benefit options. Actuarial valuations are often needed to determine present value, and the assumptions used — discount rate, mortality tables — can shift the result by tens of thousands of dollars. This is one area where cutting corners on expert advice tends to be expensive.
Social Security on Your Ex’s Record
The 10-year marriage threshold is one of the most consequential rules in a long-term divorce, and a 30-year marriage clears it easily. You may be eligible to collect Social Security benefits based on your ex-spouse’s earnings record.8Social Security Administration. More Info – If You Had a Prior Marriage Claiming on your ex’s record doesn’t reduce their benefits or affect their ability to collect. The two claims are independent.
To qualify for divorced spouse benefits, you must be at least 62, currently unmarried, and not entitled to a higher benefit based on your own work history.9Social Security Administration. Who Can Get Family Benefits If your ex hasn’t yet filed for their own benefits but is eligible, you can still claim once you’ve been divorced for at least two years.
You Can’t Claim Ex-Spouse First and Grow Your Own
Older guides sometimes suggest claiming divorced spouse benefits first while letting your own retirement benefit grow to age 70. That strategy is no longer available for most people. If you turned 62 after January 1, 2016, deemed filing applies: when you file for any Social Security benefit, you’re automatically filed for all benefits you’re eligible for, and you receive whichever is higher.10Social Security Administration. Filing Rules for Retirement and Spouses Benefits
Survivor Benefits
If your ex dies and your marriage lasted at least 10 years, you may qualify for survivor benefits starting at age 60, or 50 if you have a disability. At full retirement age, the survivor benefit equals 100% of your deceased ex-spouse’s benefit. Claiming between 60 and full retirement age reduces the benefit to between 71% and 99%.11Social Security Administration. Survivors Benefits Survivor benefits can be substantially higher than divorced spouse benefits, which max out at 50% of the ex-spouse’s benefit.
What Remarriage Does
Remarrying generally ends your eligibility for divorced spouse benefits on your former spouse’s record.12Social Security Administration. Will Remarrying Affect My Social Security Benefits Survivor benefits follow a more forgiving rule: if you remarry after age 60, you can still collect survivor benefits based on your deceased ex-spouse’s record.11Social Security Administration. Survivors Benefits If you remarry before 60 and that marriage later ends, eligibility for survivor benefits can be restored. The timing of any remarriage becomes a real financial decision.
Health Coverage You Can Keep or Claim
Losing health insurance is one of the most immediate practical consequences of divorce, especially for a spouse who relied on the other’s employer plan. After 30 years, both spouses are closer to the age where coverage is more expensive and more essential.
COBRA
If you were covered under your spouse’s employer plan, divorce is a qualifying event that entitles you to continue that coverage for up to 36 months through COBRA.13U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers You must notify the plan administrator within 60 days of the divorce. Coverage mirrors what you had before, but you pay up to 102% of the full plan premium, including the portion the employer previously paid plus a 2% administrative fee.14U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Employers and Advisers For many people that means $600 to $900 or more a month for individual coverage.
Marketplace Coverage
Divorce also qualifies you for a Special Enrollment Period on the Health Insurance Marketplace, giving you 60 days from the date you lose coverage to enroll in a new plan.15HealthCare.gov. Getting Health Coverage Outside Open Enrollment Depending on your post-divorce income, you may qualify for premium subsidies that make a marketplace plan substantially cheaper than COBRA. Compare both before defaulting to COBRA.
Medicare Through Your Ex’s Work Record
If your marriage lasted at least 10 years and your ex worked long enough to qualify for Social Security (at least 40 quarters of Medicare taxes), you can qualify for premium-free Medicare Part A based on their work record once you turn 65. You must be unmarried when you apply, and the benefit is available whether or not your ex has filed for Medicare. If your ex worked fewer than 40 quarters, you may still qualify for Part A at a reduced premium rather than free. For a spouse who spent most of the marriage outside the workforce, this is a significant lifeline.
Legal Separation as a Bridge
In some cases, a legal separation rather than a divorce allows the dependent spouse to remain on the other’s employer health plan. Because legal separation does not legally end the marriage, most employer-sponsored plans continue to cover the separated spouse. The approach varies by plan and by state, but for couples where one spouse faces a coverage gap before Medicare, it can be a practical bridge. Legal separation still counts toward the 10-year Social Security marriage requirement, since the marriage hasn’t technically ended.
The Debt You’re Still On the Hook For
What you’re entitled to is only half the picture; what you owe is the other half. Mortgages, home equity lines, credit card balances, and personal loans all have to be divided. Community property states tend toward an equal split, while equitable distribution states weigh each spouse’s ability to repay, who incurred the debt, and what it was used for.
Here is the trap. A divorce decree divides responsibility between spouses, but it doesn’t bind creditors. If a joint credit card is assigned to your ex and they stop paying, the creditor can still come after you. The safest approach is to pay off or refinance joint debts before or during the divorce so each spouse’s obligations are in their name alone. Debts run up by one spouse shortly before filing, especially for non-marital purposes, often face closer scrutiny and may be assigned entirely to the spouse who incurred them.
Updating Your Beneficiaries and Estate Plan
A divorce after 30 years almost certainly means your entire estate plan needs to be rewritten. Wills, revocable trusts, powers of attorney, and healthcare directives probably all name your spouse. More than 40 states have laws that automatically revoke a former spouse’s designation as a beneficiary or executor upon divorce, but relying on those statutes is a mistake for two reasons.
First, automatic revocation only takes effect after the divorce is final. During the divorce process, which can run for many months, your existing documents remain in force. Second, and more importantly, federal law overrides state revocation statutes for ERISA-governed accounts like 401(k) plans and employer-provided life insurance. Under the Supreme Court’s ruling in Egelhoff v. Egelhoff, plan administrators must pay benefits to whoever is named on the beneficiary designation form, even if state law would have revoked that designation on divorce.5U.S. Department of Labor. Qualified Domestic Relations Orders Under ERISA – A Practical Guide to Dividing Retirement Benefits If you don’t update your 401(k) beneficiary designation after divorce, your ex could inherit the account.
Update every beneficiary designation, power of attorney, healthcare directive, will, and trust as soon as the divorce is underway. Don’t wait for the final decree. Review retirement accounts, life insurance policies, bank accounts, and transfer-on-death designations for investment and brokerage accounts. Each has to be changed individually with the institution that holds it.
Support for a Disabled Adult Child
If you have an adult child with a disability who cannot support themselves, the divorce process gets more complicated. Many courts hold that parents have a continuing obligation to support an adult child whose disability prevents them from becoming self-sufficient, particularly when the disability began before the child reached the age of majority. The key question is whether the child is unable, not unwilling, to earn a living. If the child has sufficient income or resources despite the disability, courts are less likely to order continued parental support. This obligation can be factored into the settlement and may affect how alimony or property division is structured.
