Why You Cannot Get a Secured Loan on Someone Else's Property
A secured loan requires the borrower to grant the lender a legal charge over the property. To grant that charge, the borrower must have a legal interest in the property — they must be on the title deeds at the Land Registry. A third party cannot grant a charge over a property they do not own, regardless of the property owner's consent.
Even if a family member gives you permission to use their property as security, this does not give you a legal interest in it. The lender would require you to be added to the title deeds first — which has its own legal, financial, and tax implications, including potential Stamp Duty Land Tax liability and a change in the property's ownership structure. This is a significant step and not one to take lightly without independent legal advice.
A second charge mortgage or secured loan also cannot be structured as a joint borrower sole proprietor (JBSP) arrangement in the way that some first charge mortgages can. JBSP mortgages allow a parent to be named on the mortgage for affordability purposes without being on the property deeds, but this product structure is not generally available for second charge lending. If a JBSP-style arrangement is what you need, a first charge remortgage — replacing the existing mortgage rather than adding to it — may be the only route that accommodates it.
Using Your Own Property to Help a Family Member
The most straightforward way to release money from property to help a family member is to take a secured loan or further advance against your own home and then gift or lend the proceeds. This is entirely legal, subject to the usual secured loan criteria — equity, income, credit — and the lender will not typically restrict what you do with the funds once released, provided you do not misrepresent the purpose on the application.
If you are gifting the money, this may have inheritance tax implications if you die within seven years of making the gift. The current annual gift allowance is £3,000 per year, and gifts above the nil-rate band may be subject to IHT if you do not survive seven years. Speak to a financial adviser or solicitor before making large gifts to family members using secured borrowing.
If you are lending the money to a family member, documenting the arrangement as a loan — even between family members — is strongly advisable. A simple loan agreement setting out the amount, the interest rate (even if zero), and the repayment terms protects both parties and avoids ambiguity later. It also provides documentation if HMRC ever asks about the transaction.
