Cosigning a mortgage does not give a cosigner any rights to the house. The Federal Trade Commission puts it plainly: cosigning a loan gives you no title, ownership, or other rights to the property the loan pays for.1Federal Trade Commission. Cosigning a Loan FAQs Your signature guarantees the debt if the primary borrower stops paying. It does not put you on the deed, and it does not let you live in, sell, or inherit the home.
Why the Mortgage and the Title Are Separate
Two different documents run in parallel when a house is bought with financing. The mortgage note is the debt obligation — who has promised to repay the lender. The title, sometimes called the deed, is the legal document establishing who owns the property. A cosigner’s name goes on the note and stays off the title. That single fact drives almost everything else about a cosigner’s position.
A co-owner, by contrast, appears on both. Their name sits on the title, giving them a legal ownership stake, and they typically share the loan as a co-borrower. Most cosigning arrangements are not co-ownership arrangements. You are being added to the debt to strengthen the lender’s collateral, not being given a piece of the house.
What You Cannot Do as a Cosigner
Because a cosigner has no ownership interest, the everyday rights of a homeowner are simply not yours.1Federal Trade Commission. Cosigning a Loan FAQs You cannot move into the home without the owner’s permission. You cannot force a sale. You cannot pull equity out through a refinance or a home equity loan. If the owner sells, you get none of the proceeds, even if you have been making the payments.
Inheritance works the same way. If the primary borrower dies, the house passes to whoever is named in their will. Without a will, state intestacy laws control, and those laws typically prioritize a surviving spouse and children before other relatives.2Legal Information Institute. Intestate Succession You do not inherit the house because you cosigned. You do, however, still owe the money. The lender can require you to keep paying on a property you have no right to enter.
What the Lender Can Still Do to You
The lender’s reach is broader than most cosigners expect. In most states, the lender can pursue the cosigner for payment without first trying to collect from the primary borrower, and can use the same collection tools available against the borrower, including lawsuits and wage garnishment.1Federal Trade Commission. Cosigning a Loan FAQs Some states require the lender to try the borrower first. Many do not.
The lender is also not required to tell you when a payment is missed. You can ask for monthly statements or for notice of missed payments, but the lender does not have to agree.1Federal Trade Commission. Cosigning a Loan FAQs If they do agree, you may be able to cover a late payment before the loan is accelerated, which is far cheaper than being asked for the full remaining balance. Getting that agreement in writing before closing is one of the few protective steps a cosigner can take.
If You End Up Making the Payments
Paying on a house you do not own is not entirely without recourse against the borrower. Under a doctrine called subrogation, a cosigner who repays a loan steps into the lender’s shoes and takes on the lender’s rights against the borrower. If you make mortgage payments the borrower should have made, you can sue the borrower to recover what you paid.
That right exists without any written agreement, but enforcing it in court is slow and expensive. A better approach is to sign an indemnity agreement with the borrower before the loan closes. This is a private contract, separate from the mortgage, in which the borrower agrees to reimburse you for any payments you cover. Useful provisions include a reimbursement timeline, collateral backing the borrower’s promise, and automatic triggers requiring the borrower to refinance you off the loan after a set period or number of on-time payments.
The Exception: When a Cosigner Is Also on the Title
Sometimes the person a lender labels a “cosigner” is actually added to both the mortgage and the deed. That person is a co-owner, with real rights in the property. The rights depend on how title is held, and there are three common forms.
Tenancy in Common
Each owner holds a separate share, and shares can be unequal. An owner can sell, gift, or bequeath their share without the other owner’s consent.3Legal Information Institute. Tenancy in Common There is no right of survivorship, so when one owner dies, their share passes to their heirs rather than to the other co-owner.
Joint Tenancy
Each owner holds an equal, undivided interest in the whole property. The defining feature is the right of survivorship: when one owner dies, the surviving owner automatically takes the deceased owner’s share.4Legal Information Institute. Right of Survivorship That right can be severed if an owner sells or transfers their interest, which converts the arrangement into a tenancy in common.
Tenancy by the Entirety
Available only to married couples in most states that recognize it, this form resembles joint tenancy with extra protection. Neither spouse can sell or transfer their interest without the other’s consent, and creditors of one spouse generally cannot force a sale of the property.5Legal Information Institute. Tenancy by the Entirety
A co-owner who wants out can file a partition action, a lawsuit asking a court to divide the property or, more commonly for a single home, order it sold and the proceeds split. Courts treat the right to partition as essentially absolute unless it has been waived in a binding agreement.
What the Mortgage Does to Your Credit and Borrowing
A cosigned mortgage sits on your credit report as if it were your own debt. Every on-time payment helps your credit history; every late payment hurts it. A default lands on your record too.1Federal Trade Commission. Cosigning a Loan FAQs
Less obvious is the impact on your own borrowing. When you later apply for a mortgage of your own, lenders count the cosigned debt in your debt-to-income ratio.6Fannie Mae. Debt-to-Income Ratios That extra monthly obligation can push your DTI over the approval threshold and effectively keep you from buying your own home until the cosigned loan is paid off or you are released from it.
Taxes: No Ownership, No Deduction
The cosigner’s lack of ownership carries a concrete tax cost. To claim the mortgage interest deduction, the IRS requires that you have an ownership interest in the home and that the mortgage is secured debt on that property.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction A cosigner who is not on the title fails the ownership test and cannot deduct any mortgage interest they pay, even if they are the one writing the checks.
How to Get Off the Loan
The cleanest way out is for the primary borrower to refinance the mortgage into their name alone. The new loan pays off the old one and ends the cosigner’s obligation. The borrower has to qualify on their own credit and income, which may be the reason they needed a cosigner in the first place.
Some loan agreements include a cosigner release clause that allows removal after the borrower shows a record of on-time payments and adequate creditworthiness. These clauses are uncommon in standard mortgage contracts. Without the borrower’s cooperation, a cosigner cannot unilaterally step off the loan. You signed a binding contract with the lender, and only the lender can release you. The best time to negotiate an exit is before you sign, by getting the borrower to commit in writing to refinance within a specific window and by confirming whether any release provision exists in the loan terms.
