Yes — and debt protection is one of the most common reasons couples get a prenup at all. Here's exactly what a prenup can do about student loans, credit cards, business debt, and medical bills, and the two things it can't.
A prenup can designate your partner's debts — existing and future — as their separate responsibility, so a divorce court doesn't divide them between you.
A prenuptial agreement lets you and your partner decide, in advance and in writing, whose debt is whose. The standard approach is simple: debt each of you brings into the marriage stays with the person who incurred it, and debt taken on during the marriage in one person's name stays theirs unless you both agree otherwise in writing.
That matters because divorce courts don't just divide property — they divide debt. Without an agreement, the loans, balances, and obligations accumulated during your marriage get classified and split under your state's default rules, and those rules were not written with your situation in mind. A prenup replaces that default with the answer you actually chose. For what those defaults look like where you live, see the prenup laws in your state.
By default, debt you each brought into the marriage generally stays separate — but debt incurred during the marriage can become a shared obligation, depending on your state.
The good news first: in every state, debt you incurred before the wedding generally remains your separate obligation. Marrying someone does not, by itself, make you liable for their old student loans or credit-card balances.
The during-the-marriage picture is messier. In equitable-distribution states (most of the country), debts incurred during the marriage are typically treated as 'marital debt' and divided fairly — which does not always mean equally, and does not always track whose name is on the account. In community-property states, the situation can be sharper: debts incurred during the marriage are generally community obligations, and in some circumstances shared assets can be reached to satisfy one spouse's debts. The label on the loan matters less than people assume; the state's classification rules control.
A prenup overrides those classification rules with your own. That's the whole trick — you're not hiding from creditors, you're deciding in advance how debt is allocated between the two of you if the marriage ends.
Marrying someone doesn't have to mean marrying their student loans. But if you don't put that in writing, your state gets to decide.

A prenup can address each major debt type — the mechanics differ slightly, but the principle is the same: name it, classify it, and keep it separate.
Student loans are the classic case, and the most common one we see. Loans taken out before the marriage stay separate by default — but payments made on them during the marriage with shared income can create reimbursement fights, and loans taken out during the marriage (say, for a graduate degree) can be classified as marital debt in some states. A prenup can keep both the loan and the degree-holder's obligation cleanly separate.
Credit cards follow the account. A card in your partner's name alone is generally their debt — but a joint account, or a card you're a co-signer on, is a shared obligation regardless of who did the spending. A prenup can require that shared accounts stay limited, and can allocate responsibility for balances if you divorce.
Business debt deserves special attention if either of you is an owner. Business loans often come with personal guarantees, and a struggling business can pull marital assets in after it. A prenup can wall the business — and its liabilities — off as separate property, which is also the core of our guide to prenups for business owners.
Medical debt is the one people don't see coming. Most states have some version of the 'doctrine of necessaries,' under which a spouse can be pursued for the other's necessary medical expenses. A prenup can't always stop a hospital from billing you — but it can require that the responsible spouse indemnify the other, so the cost ultimately lands where you agreed it should.
| Default (no prenup) | With a prenup | |
|---|---|---|
| Premarital student loans | Borrower's separate debt, but shared income used for payments can blur the line | Loan and any payments stay the borrower's responsibility |
| Loans taken during marriage | Often classified as marital/community debt, divided by state rules | Stay with the spouse who signed, unless you both agree otherwise in writing |
| Credit cards (individual) | Usually the cardholder's, but balances run up during marriage can be divided | Cardholder keeps their own balances |
| Business debt & guarantees | Can reach marital assets, especially with personal guarantees | Business and its liabilities designated the owner's separate property |
| Medical debt | Doctrine of necessaries can make a spouse liable in many states | Indemnification: the responsible spouse bears the ultimate cost |
A prenup binds you and your spouse — it does not bind creditors, and it does not undo obligations you voluntarily co-sign.
First: creditors aren't parties to your prenup. If you co-sign your partner's car loan, open a joint credit card, or jointly guarantee a lease, the lender can pursue either of you no matter what your agreement says. What the prenup controls is the reckoning between spouses — it can require the responsible partner to indemnify you, meaning they must cover or reimburse what the creditor collected from you.
Second: a prenup is not a fraud shield. Courts won't enforce an agreement designed to hide assets from existing creditors or dodge obligations you already owe. The honest version of debt protection — full disclosure, clear allocation, signed well before the wedding — is also the enforceable version. That's the version a properly built agreement gives you.
Debt protection is the #3 reason couples start a Trusted Prenup — cited by more than 1,000 of 2,840 couples in our own questionnaire data.
There's a persistent myth that prenups are for people protecting fortunes. Our own data says otherwise: when we ask couples what they're hoping to accomplish, 'protect against debt' is the third most common answer — ahead of almost everything else. For a generation carrying record student debt into marriage, the most valuable thing to protect is often a clean balance sheet.
It also cuts both ways, which is why the conversation is easier than people fear: the partner with the debt usually wants the agreement too. Nobody plans to hand their loans to the person they love. Putting it in writing isn't an accusation — it's a mutual promise that each of you keeps your own. If you're not sure how to raise it, start with our guide on how to talk to your partner about a prenup.
List every existing debt honestly, set a rule for future debt, and put both in a state-compliant agreement — the Trusted Prenup questionnaire walks you through each step.
Debt protection is only as strong as its specifics. An enforceable agreement starts with full financial disclosure — both partners list what they own and what they owe. That disclosure isn't a bureaucratic hurdle; it's what makes the agreement stick, because courts look hard at whether both sides knew what they were signing up for.
From there, the Trusted Prenup questionnaire asks how you want to handle each category — premarital debt, future borrowing, joint accounts — and builds the answers into an agreement designed to meet your state's requirements. You each review it, sign, and notarize online. The whole thing costs a flat $599, which is considerably cheaper than absorbing someone else's five-figure balance.
Build a state-specific prenup with real debt protection in about 90 minutes, for a flat $599.
Start Your Prenup →Not for debt they brought into the marriage — premarital debt generally stays with the person who incurred it. But debt taken on during the marriage can become a shared obligation under your state's rules, even if it's in one name. A prenup lets you set your own rule instead.
Yes, between the two of you. A prenup can designate your partner's student loans — existing and future — as their separate responsibility, and can address repayment made with shared income. It cannot change your partner's contract with the lender, but it controls who bears the cost if you divorce.
No — creditors aren't bound by your prenup. If you co-sign or hold a joint account, the lender can pursue you regardless. What a prenup can do is require your spouse to indemnify you, so debts that were theirs in substance end up theirs in fact.
In community-property states, debts incurred during the marriage are generally community obligations, and shared assets can in some cases be reached for one spouse's debts. A prenup can opt you out of that default by keeping each partner's debts and liabilities separate. Check the rules for your state in our state guides.
Debt protection is precisely the case where a prenup helps people who aren't rich. If either of you carries student loans, credit-card balances, or business liabilities — or ever might — a $599 agreement that keeps them separate is far cheaper than dividing them in a divorce.
Yes — that's a postnuptial agreement, which works similarly but is signed after the wedding and is scrutinized more closely by courts in many states. If you're not married yet, a prenup is the cleaner tool. See prenup vs. postnup for the differences.
