What marriage does and does not do
Start by separating three things that get treated as one: who owes the money, whose property can be taken to pay it, and who reimburses whom afterward. Marriage barely touches the first, changes the second, and creates a whole set of questions about the third.
| The question | What marriage generally does to it |
|---|---|
| Am I personally liable for a debt my spouse took out before we married? | Generally no. Liability follows the promise, and you did not make it. Some states impose liability for debts incurred for necessaries, which is a narrow category. |
| Can a creditor of my spouse take property that I think of as mine? | This is the real question. In a community-property state, income earned during the marriage is shared property, and how much of it is exposed depends on who manages it and what kind of debt is involved. |
| If married money pays down my spouse's debt, do I get that back? | That is a reimbursement question between the two of you, and states answer it differently. It has nothing to do with the lender. |
| What about a debt we both signed for? | You are both liable to that lender, and nothing between the two of you changes it. Co-signing is a promise to the creditor. |
Texas states the first of those as clearly as any statute in this corpus. A person is personally liable for the acts of their spouse only if the spouse was acting as their agent, or incurred a debt for necessaries, and the section then closes the argument most people would reach for by providing that a spouse does not act as an agent for the other solely because of the marriage relationship.
The exception that catches people is joint credit rather than marriage. Adding your name to a card, refinancing a mortgage into both names, or co-signing anything makes you liable to that lender directly. Liability of that kind arrives by signature rather than by wedding, and it is not undone by anything the two of you agree afterward.
Source 1Why a creditor is not bound by your agreement
This is the single most important thing on the page and it is a point about contracts rather than about marriage. An agreement binds the people who signed it. A lender who was not there did not agree to anything and does not lose a right because two other people wrote something down.
What an agreement can doWhat it cannot do
Both are true at once, and confusing them is expensive.
Say that a debt is one person's responsibility as between the two of youStop the lender pursuing whoever promised to pay
If both of you signed, both of you are still liable to that lender.
Create a right of reimbursement if one of you ends up paying the other's debtPrevent the creditor collecting in the first place
Reimbursement is a claim against your spouse, not a defense against the lender.
Fix the character of property so it is clear whose it isPut property beyond a creditor who already has a claim against it
Rearranging property to defeat an existing creditor has its own consequences, and this is a question for counsel rather than a planning idea.
Record what each of you brought, so it can be proved laterChange what state law says a creditor may reach
The exposure rules are statutory. The agreement operates on the couple, not on the statute.
Which means the phrase "a prenup to protect me from their debt" describes something real and something narrower than it sounds. It protects your position relative to your spouse. Whether a creditor can reach a particular asset is answered by your state's rules about marital property, and the agreement's contribution is that it can help fix which property is whose.
Source 1What an agreement can usefully do about debt
Having narrowed it, the useful work is real and worth naming, because a couple with one person's student loans on the table has several decisions to make that state law will otherwise make for them.
- Say which debts each of you brought, in a schedule specific enough to be evidence years later rather than a summary.
- Say what happens if married earnings are used to pay down a debt that one of you brought, and whether that is accounted for.
- Say whether either of you may take on debt secured against property the other brought.
- Say how debt incurred during the marriage is treated between you, which is a different question from who the lender pursues.
- Say what happens to a joint debt if the marriage ends, remembering that this binds only the two of you.
- Record what each of you owes at the outset, which is often required as part of the financial disclosure the agreement rests on anyway.
Texas contains a provision on this that runs the opposite way to most people's instinct. A court there may not recognize a reimbursement claim for a student loan owed by a spouse. So married earnings used to pay down a partner's student debt are not, on the face of that section, compensated by the statute. A couple who assume the default is fair may be assuming wrongly, and this is exactly the kind of thing an agreement can address deliberately.

Texas
Texas is a community-property state and answers this in unusual detail, which makes it the clearest worked example available. Start with personal liability: a person is personally liable for a spouse's acts only where the spouse acted as their agent or incurred a debt for necessaries, and marriage alone does not create the agency. Then the property rules, which are layered rather than all-or-nothing. A spouse's separate property is not subject to the other spouse's liabilities unless both are liable by other rules of law. Community property under one spouse's sole management is not subject to liabilities the other spouse incurred before the marriage, nor to the other spouse's nontortious liabilities during it. But community property that a spouse manages, alone or jointly, is subject to the liabilities that spouse incurred before or during the marriage. And there is one class where the layering stops entirely: all community property is subject to the tortious liability of either spouse incurred during the marriage. On the reimbursement side, Texas creates a claim where one marital estate confers a benefit on another, expressly including using married money to improve a spouse's real property and using time, toil, talent or effort to build the value of a spouse's separate estate. It then excludes a student loan owed by a spouse from reimbursement altogether. A premarital or marital property agreement satisfying the state's agreements chapter can waive or release those reimbursement claims, which is the point at which the couple's own decision replaces the statute's.Source 1Source 2Source 3Source 4 -
New York
New York is not a community-property state, so the question is shaped differently: there is no pot of shared marital property during the marriage for a creditor to reach into, and property is generally the property of whoever owns it. What Sahvelo has read at source in New York is the estate side rather than the creditor side, and it is worth knowing because it is where debt and marriage meet at death. The elective share a surviving spouse may claim is measured against the net estate, and in computing it debts, administration expenses and reasonable funeral expenses are deducted while estate taxes are disregarded, subject to the spouse contributing their apportioned share of those taxes. So a spouse's claim is calculated after the deceased spouse's debts, not before them. New York's rules on what a creditor of one spouse may reach during a marriage are not read here, and nothing on this page states them.Source 5
Sahvelo has read all two of these states at their own sources. Another state's rule may differ, and we would rather say that than generalize.
Questions people ask about this
-
Am I responsible for my spouse's student loans?
Not the loan itself, in the ordinary case. You did not sign the promissory note and marriage does not generally make you a party to it. The exposures worth understanding are different ones. If you refinance those loans into both names, or co-sign anything, you become directly liable to that lender. If you live in a community-property state, income earned during the marriage is shared property and some of it may be reachable depending on who manages it and what kind of debt it is. Texas adds a specific point in the other direction: it will not recognize a reimbursement claim for a student loan owed by a spouse, so married earnings used to pay it down are not compensated by that section. There is a separate question this page does not answer. Repayment terms on federal student loans are set by the program and administered by the servicer, not by state law, and Sahvelo has not verified how marrying or filing a joint return bears on them. That is worth putting to the loan servicer before your first joint return rather than after it, because it is a question about the repayment arrangement rather than about who owes the debt.Source 1Source 2 -
Does living in a community-property state change this?
It changes the second question rather than the first. Community-property states create a category of property that belongs to the marriage rather than to either person, and what a creditor may reach in that category is answered by statute. Texas, read here, protects separate property and protects community property under the other spouse's sole management from premarital and nontortious debts, while exposing the community property a spouse manages to that spouse's own debts and exposing all community property to either spouse's tort liability during the marriage. Those are specific rules from one state and should not be assumed to be the rules everywhere, including in other community-property states.Source 1 -
What about tax debt?
Tax is its own subject and it does not follow the pattern on this page. Filing jointly generally makes both spouses responsible for what is on that return, which is a consequence of the filing rather than of the marriage, and there are federal relief routes for a spouse who did not know about an understatement. Debt one person owed before the marriage is a different question again. Sahvelo has not verified the federal rules on this, so it names the subject rather than answering it: this is one to put to a tax professional, and it is worth raising before a first joint return rather than after. -
Can an agreement stop my spouse's creditors reaching my house?
It can help establish that the house is yours rather than shared, which in a community-property state is doing real work, because the exposure rules turn on how property is characterized. What it cannot do is take property out of the reach of a creditor who already has a claim against it, and rearranging property with that aim has consequences of its own. If a creditor is already pursuing your spouse, this is a question for a lawyer now rather than a planning question. -
My state is not one of the two. What do I ask?
Three questions. Is this a community-property state, and if so which property falls into that category? What are the rules about which property a creditor of one spouse may reach, and do they distinguish debts incurred before the marriage from those incurred during it? And does this state recognize a reimbursement claim between spouses where married money pays one person's separate debt? Sahvelo asserts nothing about the states it has not read.
