My hubby and I have separated. I still live in our home with our son. He pays mortgage but I am not on mortgage. He is currently looking at remortgaging. Can he do this and can I ask to go on the mortgage?

Answered by: Nicholas Mendes

Yes – if your husband is the sole borrower (and the property and mortgage are only in his name), he can usually apply to remortgage without needing your permission.

But because you live there with your son, there are still important safeguards and practical steps you should take.

Can he remortgage while I’m living in the property?

Often, yes. Most lenders will still proceed, but they will normally require you to be disclosed as an adult occupier and to sign an occupier consent / waiver form.

That form is there to confirm you understand there will be a mortgage on the property and that, if the lender ever had to repossess, your right to remain in the property doesn’t override the lender’s charge.

It doesn’t make you responsible for the mortgage. It’s about the lender protecting their security.

Can he remortgage and release equity?

Potentially, yes -and this is the part that can matter most in a separation.

If he remortgages to raise extra money, that can reduce the equity in the home. Depending on your marital/financial arrangements, that equity may not be “his” alone in the wider sense, even if you’re not on the mortgage.

That’s why it’s important not to treat this as purely a mortgage admin issue. It can have real consequences in a separation.

Can you ask to go on the mortgage?

You can ask, but it’s not something you can insist on.

To add you to the mortgage, the lender will treat it like a new application and assess affordability, credit history, and the overall case. If accepted, it’s usually done via a transfer of equity (because it often involves changing ownership as well).

A couple of practical points:

  • Being added to the mortgage usually means you become jointly liable for the full debt, not just “your half”.
  • If you’re not also being added to the title deeds, you should get legal advice, because mortgage liability without ownership is rarely a good outcome.

The big missing piece: are you on the title deeds?

You said you’re not on the mortgage, but it’s not clear whether you’re on the title deeds.

That changes everything.

  • If you are on the deeds: he cannot generally remortgage without your involvement, because you’d need to sign the mortgage deed / legal charge.
  • If you are not on the deeds: he can usually remortgage, but you may still have matrimonial rights or a beneficial interest, and you should get advice quickly.

What you should do next

  1. Check the title register (or ask your solicitor) to confirm who is on the deeds.
  2. If you’re separating, speak to a family solicitor straight away, particularly if he is planning to raise additional borrowing.
  3. If you’re asked to sign an occupier consent form, don’t do it blindly – ask what the remortgage is for (straight rate switch vs borrowing more).

1. First Charge - I understand that a first charge mortgage could be a more cost-effective alternative to a second charge and have considered this before proceeding.

2. Existing Mortgage Product - I am currently tied into a mortgage product with an early repayment charge if I choose to leave this deal early and I have investigated the possibility of a further advance from my existing lender.

3. Product Suitability - I understand that second charge mortgages may not be suitable in all situations and that advice will be provided by our second charge partner “The Loan Partnership” to help determine if this is the right solution for me.

4. Data Sharing Consent - I agree that my name and contact information can be shared with a trusted partner firm – The Loan Partnership – to receive personalised advice on second charge options.

5. Understanding of Risk - I understand the risks associated with securing other debts against my home and my home may be repossessed if I do not keep up repayments on a mortgage or any debt secured against it. I am also aware that by consolidating existing borrowing that I may be extending the terms of the debt and increasing the total amount I repay.
