Taking an Ex Off the Mortgage: How It Actually Works
29 January 2026 · Mary Molloy Solicitors
The most common misconception in this area: that removing a name from the mortgage is an administrative request. It is not. The bank's loan was underwritten on two incomes, and releasing one borrower is a fresh credit decision — which is why the practical route is nearly always a full sole-name remortgage combined with a transfer of the title.
Why the bank will not just delete a name
Both borrowers are jointly and severally liable for the whole loan — the lender can pursue either for all of it. Releasing one borrower halves the covenant, so the lender must be satisfied the remaining borrower qualifies alone, at current criteria. Whatever the separation agreement says between the parties, it does not bind the bank; liability ends only with redemption or a formal release.
The transaction that actually does it
The standard structure: the retaining party obtains a sole-name loan offer (from the existing lender or a new one), the departing party signs a deed of transfer of their share, and on one completion day the new loan redeems the joint mortgage, funds any buyout payment, and the transfer and new charge are registered. The old mortgage's redemption is what finally releases the departing party from liability.
Where family law fits
For spouses and civil partners, the transfer usually happens on foot of a court order or ruled settlement, which also unlocks stamp duty and tax treatment unavailable to others. The sequencing rule that saves months: test the retaining party's mortgage approval before terms are finalised, so the settlement is built around finance that actually exists. Each side should have independent advice — one firm cannot act for both on a buyout.
If the numbers do not work yet
Where the retaining party cannot yet carry the mortgage alone, interim arrangements exist — agreed occupation with the joint loan continuing, deferred sale provisions, or revisiting once income recovers. These are family law and financial questions as much as conveyancing ones, but they should be structured deliberately, in writing, with the lender kept onside — not left as an informal drift that a missed payment turns into a joint credit problem.
