For couples with student debt
Does student debt become shared once we get married?
Not automatically. Loans taken out before the wedding are typically the separate responsibility of the borrower. What is less automatic is what happens to that debt during the marriage, when payments come from joint income, loans get refinanced, or a joint tax return changes the monthly bill. A prenup lets you settle all three in advance. Neptune is the lawyer-led online prenup service: both partners get their own lawyer for one flat fee.
Flat fee of $5,000 per couple. No payment to get started.
Where the clean answer gets messy
Separate by default, but three things can change that
Marrying someone with student loans does not make their debt legally yours. Federal and private loans stay with whoever borrowed them. The complications come from how a married household actually handles money, not from the marriage itself.
Paying it down with marital income
A loan taken out before the wedding is typically the separate responsibility of the borrower. But if payments come from a joint account or from income earned during the marriage, the paying spouse can later argue those contributions deserve credit or reimbursement.
Refinancing after the wedding
Refinancing for a better rate is common once a household has two incomes. If the new loan is issued in both names, what was once one partner’s separate debt can become a joint obligation the other partner is now directly liable for.
Filing taxes jointly
Federal income-driven repayment plans generally use combined household income when a couple files taxes jointly, and only the borrower’s income when they file separately. Filing status is a repayment decision now, not just a tax one.
The part couples do not expect
Your tax filing status can change the monthly payment
Repayment plans for federal student loans changed in 2026. For a married borrower on an income-driven plan, how you file taxes each year is now one of the biggest levers on the monthly bill.
Filing jointly
Most income-driven repayment plans, including the Repayment Assistance Plan that launched in mid-2026 and Income-Based Repayment, calculate the borrower’s monthly payment using both spouses’ combined income when the couple files a joint tax return.
Filing separately
Filing a separate return generally limits the repayment calculation to the borrower’s own income, which can lower the monthly payment. Filing separately also gives up certain tax benefits, so the tradeoff is worth reviewing with a tax professional, not assumed.
Couples in a handful of states that split marital income between spouses may see a smaller effect from filing separately than couples elsewhere. A prenup does not decide your tax filing status for you, since that is a household finance decision made year to year, but it can address how the couple approaches loan repayment and shared expenses more broadly. Your attorney and a tax professional can help you weigh the options for your situation.
What a prenup can address
Six places student debt meets prenup planning
Loans brought into the marriage
A prenup can state plainly that student loans taken out before the wedding remain the sole responsibility of the borrower, regardless of how payments are later made or which account they come from.
Loans taken on during the marriage
Some couples plan for one partner to return to school after the wedding. A prenup can address in advance whether new borrowing during the marriage is treated as separate or shared.
Reimbursement for marital contributions
If marital income helps pay down one partner’s premarital debt, a prenup can specify upfront whether that creates any right to reimbursement or credit, rather than leaving it for a court to decide later.
Refinancing during the marriage
The agreement can address what happens if a loan is refinanced jointly, so a decision made to get a better interest rate does not unintentionally convert separate debt into a shared obligation.
Cosigned and Parent PLUS loans
A cosigner is directly liable for a loan in a way a spouse typically is not. A prenup can address how a cosigned obligation, or a parent’s Parent PLUS loan taken on for a partner, factors into the couple’s finances.
Credit cards and other debt alongside student loans
Student debt rarely arrives alone. A prenup can address other premarital debt the same way, so every obligation each partner brings in is accounted for in one place.
A clear comparison
Template platform vs lawyer-led prenup
A fill-in-the-blank form can state that a loan is separate debt. It cannot address reimbursement for marital paydown, a cosigned loan, or what happens if you refinance together. Here is how a template compares with a lawyer-led prenup for student debt.
| Feature | Template platform | Lawyer-led prenup (Neptune) |
|---|---|---|
| States who is responsible for pre-marital loans | Generic separate-debt clause | Defined for your specific loans |
| Addresses reimbursement for marital paydown | Rarely distinguished | Addressed in the agreement |
| Covers cosigned and Parent PLUS loans | Not considered | Reviewed by your attorney |
| Independent counsel for each partner | None | A separate attorney for each of you |
| Cost | Low upfront, unclear if it holds up | $5,000 flat, both attorneys included |

Common questions about student debt and prenups
Am I responsible for my partner’s student loans once we get married?
Marrying someone with student loans does not make their debt legally yours. Federal and private loans your partner took out before the marriage stay their individual responsibility. The two situations where that can change are cosigning a private loan or refinancing the debt into a new loan in both of your names. Rules for how debt is treated can also differ by state, and your attorney can review what applies where you live.
If we pay down the loan together, does that create a claim later?
It can, without something in writing. If loan payments are made from a joint account or from income earned during the marriage, the paying spouse’s contributions may later be raised as a reason for reimbursement or credit, even though the loan itself stays in the borrower’s name. A prenup can specify upfront whether marital contributions toward a partner’s premarital debt create any right to reimbursement, so it is settled in advance rather than argued from scratch.
Does filing taxes jointly change our student loan payments?
It can. Most income-driven repayment plans, including the Repayment Assistance Plan and Income-Based Repayment, generally use combined household income to calculate the borrower’s monthly payment when a couple files a joint tax return, and only the borrower’s individual income when they file separately. Filing status is reviewed annually as part of loan recertification, and the tradeoffs against joint-filing tax benefits are worth reviewing with a tax professional. A prenup does not set your tax filing status, but it can address how the couple approaches loan repayment strategy more broadly.
What if we refinance the loans together after the wedding?
Refinancing for a lower rate is common once a household has two incomes, but doing it jointly can convert what was one partner’s separate debt into an obligation you are both directly liable for. A prenup can address this in advance, so a refinancing decision made for a better rate does not quietly change who is responsible for the debt if the marriage ends. Your attorney can review the mechanics for your situation.
What does it cost and how long does it take?
Neptune charges a flat fee of $5,000 per couple, which covers two independent attorneys, one for each partner. No payment is required to get started. Turnaround is typically around 3 to 4 weeks when both partners use Neptune attorneys. Rush pricing applies when the wedding is within 45 days.
