If you're helping your child buy with a joint borrower sole proprietor (JBSP) mortgage, you take on the whole mortgage without owning any of the home. Here's what that means in practice, what happens if payments are missed, and how and when you can come off it.

Key takeaways
With a JBSP mortgage, the buyer owns the home and you join the mortgage to boost the income the lender can count. You’re a borrower but not an owner. For how it works, see JBSP mortgages explained. This guide is about the parent’s side.
All the borrowers are jointly and severally liable. The lender can ask you for the full monthly payment, the arrears or, if the home is repossessed and sold for less than is owed, the shortfall. It doesn’t matter that you’ve never lived there or that your child agreed to pay.
You aren’t on the title, so you have no share in the property and no say if your child decides to sell or remortgage, unless something is separately agreed and recorded.
The mortgage shows on your credit file. Missed payments affect your score as well as your child’s, and other lenders will count the JBSP payments when you apply to borrow for yourself, for example to remortgage your own home.
Lenders usually contact all the borrowers once payments are missed. You can then pay, help your child sell, or agree a plan with the lender. Act early: arrears grow, and a repossession sale rarely achieves full value. If the relationship has broken down, take advice promptly, as you may have a claim against your child for what you’ve paid.
Yes, but only with the lender’s agreement. You can’t simply resign from it. The lender will release you if your child can show they can afford the mortgage on their own, under its lending rules at the time. That usually means:
Your child’s income has usually risen since they bought, which is what makes this possible. Talk to a mortgage broker a few months before the fixed rate ends. If your child still can’t afford it alone, the options are to stay on, add another borrower, or sell.
A short written agreement between you and your child avoids misunderstandings later. It can cover who pays the mortgage, what happens if your child can’t, any money you’re putting in and whether it’s a gift or a loan, and when your child will try to remove you. It doesn’t bind the lender, but it records what you agreed.
Because you take on full liability without owning anything, most JBSP lenders require you to be advised by a solicitor who isn’t acting for your child, and to sign a certificate before completion. It’s usually done by video call. See ILA for a JBSP mortgage.
Your child applies to the lender to remove you, usually at a remortgage or the end of a fixed rate. The lender agrees if your child can afford the mortgage alone under its rules at the time.
Yes. All borrowers are liable for the whole mortgage, so the lender can ask you for the payments and any arrears.
No. Only your child is on the title, unless you agree and record something separately.
Yes. It shows on your credit file, missed payments affect your score, and other lenders count it when you borrow.
Usually not. Lenders normally want advice from a solicitor independent of your child.
