Debt is divided in a divorce much like property, and it can be just as hard to sort out as the family home or a retirement account.

Married couples often share credit cards, car loans, and mortgages, so ending a marriage means deciding who will keep paying each balance.

According to WalletHub, the average U.S. household owed over $155,000 in debt at the end of Q2 2026.

A divorce attorney can help spouses list every debt, trace when and why each balance was taken on, and argue for a fair split. Legal guidance can also bring hidden or forgotten accounts to light before the divorce is final, when they are much easier to address.

Are Debts Considered Marital Property?

Whether a debt counts as marital property depends a great deal on the state where the divorce is filed. Most states follow a system called equitable distribution. In these states, debts taken on during the marriage are usually considered marital, but a judge divides them in a way that seems fair rather than automatically down the middle. A judge might look at each spouse’s income, who ran up the balance, and who benefits from the item the debt paid for.

A smaller group of states, including California, Texas, Arizona, and Washington, follow community property rules. In these states, debts incurred during the marriage are generally treated as belonging to both spouses. Some community property states lean toward an equal split, while others still give the judge room to divide debts in a just manner.

In nearly every state, some debts are considered separate. A student loan or credit card balance from before the wedding often stays with the spouse who brought it into the marriage. Debts taken on after a couple separates may also be treated as separate, though states disagree on when a marriage legally ends for this purpose. Courts may also assign a debt to one spouse when it served only that person, such as gambling losses or money spent on an affair. Things get murkier when separate and shared money mix together over a period of years.

What Kinds of Debt Are Often Incurred During a Marriage?

Married couples tend to build up debt in many forms over the years, some of it planned and some of it unexpected. Common types of debt that come up during a divorce include:

• Mortgages and home equity loans: The family home is often the largest debt a couple shares, and deciding who keeps the house usually means deciding who keeps the loan.
• Auto loans: Car payments are frequently tied to the spouse who drives the vehicle, though both names may appear on the loan.
• Credit cards: Joint cards and individual cards used for household spending can both end up on the table, and balances can be hard to trace.
• Student loans: Loans taken out during the marriage may be treated as marital in some states, while others assign them to the spouse who earned the degree.
• Medical bills: Costs from a hospital stay, surgery, or ongoing care can add up quickly, especially when insurance does not cover everything.
• Personal and business loans: Money borrowed to start a business or cover a gap in income may be divided differently depending on who controls the business and how the funds were used.
• Tax debt: Couples who filed joint tax returns may both be responsible for unpaid taxes, penalties, and interest from those years.

Each debt comes with questions about ownership, benefit, and responsibility. Gathering account statements, loan documents, and credit reports for both spouses can give a clearer picture of what is actually owed before negotiations or court hearings take place.

Can a Prenup Specify Who Pays for Which Debts?

A prenuptial agreement can specify which spouse is responsible for certain debts, both those brought into the marriage and those taken on later. Many couples use a prenup to keep one partner’s student loans, business debts, or credit card balances from becoming a shared burden. A prenup can also set out how future debts will be handled if the marriage ends. Couples who are already married can sometimes reach a similar arrangement through a postnuptial agreement.

For a prenup to hold up, it generally needs to be in writing, signed voluntarily, and based on honest disclosure of each person’s finances. Many states have adopted some version of the Uniform Premarital Agreement Act, which sets out basic rules for these contracts.

A court may refuse to enforce terms that were hidden, signed under pressure, or extremely one-sided. It is also worth knowing that a prenup is an agreement between spouses only. A lender who was not part of that agreement can still pursue anyone whose name is on the loan.

The Problems With Dividing Debt in a Divorce Decree

A divorce decree can assign each debt to one spouse, but creditors are not bound by that decision. A credit card company or lender agreed to a contract with the people who signed for the account, and the divorce court cannot rewrite that contract. If both spouses are listed on a loan and the decree assigns it to one of them, the lender can still go after the other spouse if payments stop.

This gap between the decree and the loan agreement can cause serious problems long after a divorce is final. Missed payments by an ex-spouse can damage the other person’s credit score, lead to collection calls, and even result in a lawsuit for the unpaid balance. The spouse who was not supposed to pay can ask the divorce court to enforce the decree, but that process takes time and money and does not erase the credit damage. The situation can become even more tangled if the responsible ex-spouse files for bankruptcy.

Couples often try to limit these risks before the divorce is final. Common steps include refinancing joint loans into one name, selling shared property to pay off balances, closing joint credit cards, and adding terms to the agreement that require one spouse to repay the other for any debt they fail to cover. None of these steps removes every risk, but they can reduce the chance that one person’s financial future stays tied to the other’s choices.
