How Debt Is Divided in a Michigan Divorce

Michigan's equitable distribution doctrine covers debts along with assets. Every dollar of debt accumulated during the marriage is part of the marital estate — and the court divides it based on fairness, not automatically 50/50.

The biggest misconception: whose name is on the account does not determine who pays. A credit card in your name alone that was used for household expenses is still marital debt subject to division.

Marital Debt vs. Separate Debt

Michigan courts classify debt the same way they classify assets — by when it was acquired and how it was used:

Marital debt: Any obligation incurred during the marriage that benefited the household or was jointly undertaken. This includes joint credit cards, the mortgage, home equity lines of credit, car loans, medical bills, and tax liabilities from joint filings.

Separate debt: Obligations incurred before the marriage or after separation that provided no household benefit. Pre-marital student loans, gambling debt hidden from the other spouse, and credit cards used to fund extramarital affairs are typically classified as separate.

How Courts Allocate Debt

Michigan judges typically allocate marital debt using one of two approaches:

Proportional to ability to pay: The higher-earning spouse takes on a larger share of debt, offset by receiving a correspondingly larger share of assets.

Asset-debt offset: One spouse takes the house (and its mortgage) while the other takes liquid assets and no debt. The net values are balanced.

The court considers the same Sparks factors used for property division — length of marriage, income disparity, needs of each party — when allocating debt.

Specific Debt Types

Credit cards: Joint cards are marital regardless of whose name is on them. Cards opened secretly during the marriage may be classified as dissipated debt and allocated entirely to the opening spouse if spending provided no household benefit.

Student loans: Pre-marital student loans always remain with the borrowing spouse. Loans taken during the marriage depend on how funds were used:

• Tuition and books only → separate debt (benefits one spouse's earning capacity)
• Living expenses, rent, groceries → marital debt (benefited the household)

Mortgage: Typically allocated to the spouse who retains the home, with a refinance requirement to remove the other's name. Until refinance occurs, both remain liable to the lender regardless of what the judgment says.

Tax liabilities from joint returns: Presumptively marital. Allocated equitably unless one spouse qualifies for innocent spouse relief due to the other's hidden income.

Medical debt: Marital if incurred during the marriage for either spouse or the children. The court may allocate it to the spouse with better insurance or higher income.

The Third-Party Creditor Problem

Here is what the divorce judgment cannot do: bind your creditors.

If the court orders your ex-spouse to pay a joint credit card and they default, the creditor comes after you. The divorce judgment gives you the right to take your ex back to court for contempt — but your credit score takes the hit in the meantime.

This is why the method of debt allocation matters as much as the amount. Wherever possible, pay off joint debts at closing (using proceeds from the home sale or other liquid assets) rather than relying on post-divorce payment promises.

Financial Dissipation

If your spouse wasted marital assets for non-marital purposes — gambling losses, funding an affair, reckless spending sprees, hidden purchases — Michigan courts can classify that as dissipation. The court either:

• Allocates the dissipated debt 100% to the offending spouse
• Subtracts the wasted amount from that spouse's share of the property split
• In cases of hidden assets, awards 100% of the concealed assets to the innocent spouse plus attorney and forensic accounting fees

Protecting Yourself

Document every joint debt: account numbers, current balances, minimum payments, whose name is on each account, and what the funds were used for. This inventory becomes the foundation of your debt allocation argument.

The Michigan Divorce Financial Split Guide includes a debt inventory worksheet that categorizes each obligation by type, classifies it as marital or separate, and calculates the total exposure for your settlement negotiations — so you can propose a defensible allocation rather than accepting whatever your spouse's attorney suggests.
