How Are Debts Divided in Wisconsin Divorce?

Wisconsin's community property rules don't just apply to assets — they apply to debts with equal force. Under Wis. Stat. § 766.55(1), any debt incurred by either spouse during the marriage is presumed to have been incurred "in the interest of the marriage or the family." That means both spouses are responsible, even if only one name is on the account.

This surprises people. Your spouse maxed out a credit card you didn't know existed? Under Wisconsin's family purpose doctrine, you're liable for half.

The Family Purpose Doctrine

Wisconsin's default rule is aggressive: all marital debts are joint debts. It doesn't matter that only your spouse signed the credit card application, only your spouse made the purchases, and only your spouse's name appears on the statement. If the debt was incurred during the marriage and can be characterized as serving a family purpose, both spouses are on the hook.

To challenge this presumption, the non-debtor spouse must prove the debt was clearly NOT for a family interest — funds used to support an extramarital affair, unilateral gambling losses, or drug purchases are typical exceptions that constitute marital waste.

The Creditor Rights Trap

This is the most dangerous misconception in divorce: your divorce decree does not protect you from creditors.

Under Wis. Stat. § 766.55(4m), if the court assigns a joint credit card to your spouse and they stop paying, the creditor can still sue you and garnish your wages. Creditors are not parties to the divorce. They didn't agree to your settlement. They can enforce the original contract against any signer.

Your only real protections:

• Pay off joint debts during the divorce settlement
• Require the responsible spouse to refinance joint debts into individual accounts
• Include a hold-harmless and indemnification clause in your agreement

How Different Debts Are Classified

Credit cards: Joint cards are clearly marital. Individual cards opened during the marriage are presumed marital under the family purpose doctrine. Freeze all joint credit card accounts immediately upon filing to prevent additional charges.

Mortgages: The most common joint debt. Must be either paid off through sale or refinanced into one name to release the other spouse from liability.

Car loans: If the vehicle was purchased during the marriage, the loan is marital debt. The spouse keeping the car should refinance the loan individually. If they can't qualify, the car may need to be sold.

Student loans: Premarital student loans remain individual debts. Loans taken during the marriage depend on how the proceeds were used — if they supported the household (rent, groceries while one spouse was in school), they're marital. If they paid only for tuition, the court may assign them to the spouse who received the education.

Medical bills: Under Wis. Stat. § 766.55(2)(a), a spouse's medical expenses represent a fundamental duty of support. Medical debts incurred during the marriage are marital liabilities regardless of which spouse received treatment.

Tax debt: Joint federal and state tax liabilities during the marriage are marital debts. If one spouse committed tax fraud, the other may seek Innocent Spouse Relief from the IRS and Wisconsin Department of Revenue.

The Hold-Harmless Clause

This is your contractual protection when a joint debt can't be paid off or refinanced during the divorce. A hold-harmless clause in your marital settlement agreement states that if the responsible spouse fails to pay the assigned debt and a creditor pursues you:

• The responsible spouse must reimburse all payments you're forced to make
• The responsible spouse pays any attorney fees, collection costs, and credit damage costs
• You can enforce this clause through contempt of court

It doesn't prevent the creditor from coming after you — only the divorce decree party can be held accountable through this clause. But it gives you a legal mechanism to recover losses.

Post-Separation Debt

Marital property and debts technically accumulate until the final judgment is signed. However, debts incurred after physical separation are scrutinized. Courts typically assign post-separation debts to the incurring spouse if they weren't spent on family support — especially if one spouse moved out and began accumulating new debt unrelated to the marriage.

Protecting Yourself During Divorce

1. Pull credit reports for both spouses to identify all joint accounts
2. Freeze joint credit cards immediately upon filing
3. Document all balances at the date of separation — this becomes your baseline
4. Track post-separation spending by your spouse on joint accounts
5. Insist on payoff or refinance for any joint debt where possible
6. Include hold-harmless clauses for every assigned joint obligation
