What Happens to Debts When You Divorce or Separate?

When a relationship ends, most people think first about the family home, the children, and perhaps a pension. Debt tends to be the thing nobody wants to raise, yet it is very often the issue that causes the most anxiety once the dust settles. Mortgages, credit union loans, car finance, credit cards, and revenue liabilities do not disappear simply because a marriage has.

According to the Courts Service Annual Report for 2025, 5,047 divorce applications were made that year, and 4,550 divorces were granted. Behind a great many of those files sits a joint borrowing arrangement that has to be untangled. Our family law team are often asked who becomes responsible for what, so here is a clear outline of how debt is treated on separation and divorce.

There is no automatic 50/50 split

Ireland does not operate a system of automatic equal division. Instead, the courts are required to make “proper provision” for both spouses and any dependent children. Under section 20 of the Family Law (Divorce) Act 1996, a judge must weigh up a long list of factors, including the income, earning capacity, property, and financial resources and obligations of each spouse.

Debts fall squarely within those obligations. A court will look at what the borrowing was for, who benefited from it, who realistically has the capacity to service it, and what the overall settlement looks like once everything is accounted for. A spouse who takes on the larger share of the debt may well receive a larger share of the assets to balance matters.

Sole debts and joint debts are treated differently

The starting point is whose name is on the credit agreement.

• Debt in one name only. As a general rule, the person who signed the agreement remains liable for it. Your spouse does not become responsible for your credit card simply because you were married. That said, the debt still forms part of the overall financial picture the court considers.
• Joint debt. Where both parties signed, the liability is usually joint and several. That is an important phrase. It means each of you is liable for the whole of the debt, not merely half of it. If one party stops paying, the lender is entitled to pursue the other for the full balance.
• Guarantees. If you acted as guarantor for a former partner, you remain on the hook for that guarantee until it is formally released.

Your agreement does not bind your lender

This is the single most misunderstood point in this whole area, and it catches people out repeatedly.

A separation agreement, a consent order, or a divorce decree can allocate responsibility for a joint loan between you and your former spouse. What none of those documents can do is change your contract with the bank or credit union. The lender was not a party to your family law proceedings and is not bound by them.

So, if a court order states that your former spouse is to discharge the joint car loan, and your former spouse then fails to pay, the lender can still come after you for the full amount, and the missed payments will appear on both credit records. The Central Credit Register records the repayment history of every loan of €500 or more for five years after the final payment, so the damage is not short-lived.

At McCarthy + Co, we always recommend that clients treat the lender as a separate conversation that must happen alongside the legal process, not after it. Your remedy against a former spouse who breaches an order is a return to court, which is slow, costly, and no comfort to a bank in the meantime.

The family home mortgage

The mortgage is usually the largest single liability, and the options are broadly these: one party buys out the other and takes on the loan alone, the property is sold and the mortgage cleared, or the arrangement is left in place for a defined period, often until the youngest child finishes education.

Be realistic about the first option. A lender will only release one borrower from a mortgage if satisfied that the remaining borrower can carry the repayments on a single income, and that assessment is made on current lending criteria rather than those that applied when you first borrowed. If the numbers do not work, sale is frequently the only clean outcome.

If repayments are already a struggle, do not wait. Central Bank figures show that 21,302 principal dwelling accounts were more than 90 days in arrears at the start of 2026, so this is far from unusual territory. Lenders are obliged under the Code of Conduct on Mortgage Arrears to engage with borrowers, and separated borrowers can be assessed individually.

Cohabiting couples are in a different position

Unmarried couples who separate have no automatic entitlement to a share of each other’s property or debt. A qualified cohabitant may be able to apply to court for redress under the Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010, but the thresholds are strict and the time limits are short. Joint borrowings, however, work exactly as they do for married couples, so a joint mortgage or loan remains a joint liability regardless of marital status.

Practical steps to consider

• Obtain your own credit report from the Central Credit Register so that you know precisely what is in your name, joint or otherwise.
• Cancel or freeze any joint credit cards, overdrafts, or credit union facilities that either party could draw down further.
• Notify lenders in writing that you have separated and ask what options exist.
• Keep paying what you can, even a reduced amount, because arrears accrue quickly and are hard to reverse.
• Speak to MABS, the free and confidential State-funded money advice service, on 0818 07 2000. Free financial and legal advice on mortgage arrears is also available through the Abhaile scheme.
• Where the debt is genuinely unsustainable, take advice on the formal options available through the Insolvency Service of Ireland.
