How it works

On a joint borrower sole proprietor mortgage, you join your child on the mortgage but not on the ownership of the home. The lender counts your income alongside theirs, so they can borrow more. Your child owns the home. You own no part of it.

Because you are not buying the property, the stamp duty position is your child's alone. A first-time buyer can still claim first-time buyer relief where they qualify.

What you are responsible for

You and your child are jointly and severally liable for the whole mortgage. If your child cannot pay, the lender can ask you to pay all of it.

The full debt

For as long as you remain on the mortgage.

Your credit file

The mortgage appears on your credit record and counts against any borrowing you apply for.

Your own plans

If you want to remortgage, move or borrow in later life, lenders will count your child's mortgage as your commitment.

The term

Lenders set an age limit for the end of the mortgage, which may depend on the oldest borrower. Your age may limit how long your child can borrow over.

Lenders commonly ask parents to take independent legal advice before signing, so that they understand what they are agreeing to.

Your retirement

If the mortgage runs past the age you plan to retire, the lender will want to know what your income will be then. Your pensions become part of your child's mortgage application.

Think about what would happen if you needed to help with the payments after you retire, and whether your pension income could cover it alongside your own costs. If you are relying on pensions you have not looked at for years, find out what they are worth before you sign.

Coming off the mortgage

Families may plan for the parent to come off the mortgage once the child earns enough to borrow alone. That needs the lender's agreement, or a remortgage, based on your child's income at the time. It may not be possible when you hope.

Ask the broker how the lender treats a request to remove a borrower, and plan to review it each time your child's deal ends.

If something happens to your child

If your child dies, the home passes under their will, or under the intestacy rules if they have none. You would still be responsible for the debt. If your child cannot work through illness, the lender may look to you for the payments.

Life cover and income protection for your child protect you as well. A will for your child sets out who receives the home.

Questions people ask

  • Do I own any of the home? No. Your child owns it, and you are responsible for the debt.
  • Is the home part of my estate? No, because you do not own it. How the arrangement fits with your wider estate is a question for a financial planner.
  • Can I come off later? Possibly, with the lender's agreement, once your child can borrow alone.
  • What if my child and I fall out? You remain liable until the lender releases you. Agree in advance how the payments will be met.
