One in four UK property purchases now involves financial help from family \u2014 making the so-called Bank of Mum and Dad the equivalent of a top-ten mortgage lender. Yet most of these arrangements are sealed with a handshake, a vague promise, and a dangerous assumption that “we’re family, it’ll be fine.” It often isn’t. When things go wrong, the consequences reach far beyond hurt feelings: they can trigger tax liabilities, derail future mortgage applications, and even end up before a judge. Here’s what you actually need to know before giving or receiving family financial help for a property purchase.<\/p>\n
The first thing any mortgage lender will ask when they see parental money in a bank statement is: is this a gift or a loan?<\/strong> The answer has profound implications. If it’s a gift, the lender typically requires a signed gifted deposit letter confirming the parents have no expectation of repayment and will take no interest in the property. If it’s a loan, the lender must factor the repayments into the borrower’s affordability assessment \u2014 which may reduce the amount they’re willing to lend, or scupper the application entirely.<\/p>\n Families routinely try to have it both ways: tell the lender it’s a gift while privately agreeing it’s a loan. This is mortgage fraud. It doesn’t matter that nobody intends harm. If the lender discovers the deception \u2014 and they can, particularly during arrears proceedings \u2014 the mortgage can be called in immediately. Don’t do it.<\/p>\n Inheritance Tax (IHT)<\/strong><\/p>\n A parental gift is a potentially exempt transfer (PET) for IHT purposes. If the parent survives seven years, it falls out of their estate entirely. If they die within seven years, taper relief may reduce the tax, but the gift is still aggregated with their estate. For parents whose assets already approach or exceed the \u00a3325,000 nil-rate band (or \u00a3500,000 including the residence nil-rate band where applicable), a large gift can push the estate into a 40% IHT charge \u2014 a bill that lands on the other children who inherit what’s left.<\/p>\n Stamp Duty Land Tax (SDLT) Surcharge<\/strong><\/p>\n If a parent is added to the title deed \u2014 sometimes done for “security” \u2014 and that parent already owns property anywhere in the world, the 3% SDLT higher-rates surcharge applies to the entire<\/em> purchase price, not just the parent’s share. On a \u00a3350,000 purchase, that’s an additional \u00a310,500. This catches families off guard at completion with depressing regularity. Even if the parent isn’t on the title, certain structures (like a parent buying jointly with an adult child) can trigger the surcharge if the parent already owns their own home.<\/p>\n Capital Gains Tax (CGT)<\/strong><\/p>\n Principal private residence relief shelters gains on a property that is genuinely your main home. But if a parent holds a beneficial interest and doesn’t live there, their share of any gain on sale is potentially chargeable to CGT at 18% or 24% depending on their income. This is another reason to get the ownership structure right from the outset.<\/p>\n An informal family loan with no written terms is a dispute waiting to happen. At minimum, a family loan agreement should cover:<\/p>\n Execute it as a deed, not a simple contract.<\/strong> A deed extends the limitation period for enforcement from six years to twelve \u2014 critical when family loans often stretch over a decade or more. If six years pass without acknowledgement or repayment under a simple contract, the debt may become statute-barred under the Limitation Act 1980. Parents who “didn’t want to make a fuss” can find they’ve lost their legal right to recover the money entirely.<\/p>\n If the loan is disclosed to a mortgage lender (as it must be), the child’s borrowing capacity shrinks. But the reverse is equally important: parents who deplete savings or take equity release to fund their child’s deposit may compromise their own ability to borrow later \u2014 whether for home improvements, care costs, or downsizing. Retirement plans built on the assumption that “we’ll get the money back” are dangerously fragile.<\/p>\n And if a parent goes on the mortgage itself as a joint borrower \u2014 sometimes necessary to meet affordability thresholds \u2014 they assume joint and several liability<\/strong>. The lender can pursue either borrower for 100% of the outstanding debt, not just “their share.” If the child stops paying, the parent’s home, pension, and other assets are all fair game. Furthermore, that outstanding mortgage will appear on the parent’s credit file and reduce their own mortgage capacity for any future application.<\/p>\n Where a parent takes an actual ownership interest in the property, a Declaration of Trust (Deed of Trust)<\/strong> is not a nice-to-have \u2014 it’s essential. Without one, the legal presumption for joint owners is equal beneficial shares, regardless of who contributed what. A properly drafted trust deed records:<\/p>\n The property should almost certainly be held as tenants in common<\/strong> rather than joint tenants. Joint tenancy carries an automatic right of survivorship \u2014 meaning if one owner dies, their share passes to the surviving owner regardless of their will. For a parent-child arrangement, that’s rarely the right outcome. Tenancy in common allows each party to leave their share to whoever they choose and to hold unequal interests.<\/p>\n Without these documents, either co-owner can apply to court under TOLATA 1996<\/strong> (the Trusts of Land and Appointment of Trustees Act) to force a sale \u2014 even if the other party objects. These proceedings are expensive, adversarial, and devastating to family relationships. A clear trust deed drastically reduces the likelihood of ending up there.<\/p>\n A large gift or loan to one child inevitably affects siblings’ inheritance expectations. Resentment festers when arrangements are secret or perceived as unfair. Parents should consider whether the help is an advance on inheritance (to be equalised in the will) or an outright additional benefit. Whichever it is, document it \u2014 ideally with a solicitor updating the will at the same time to ensure consistency and avoid a contentious probate dispute later.<\/p>\n Whether you’re the parent giving help or the child receiving it, take these concrete steps before a single pound is transferred:<\/p>\n Family financial help can be transformative \u2014 it can bridge the gap between renting indefinitely and owning a home. But it is never without risk, and the risks multiply when the arrangement is informal, undocumented, or built on assumptions rather than agreements. The families who navigate this successfully are the ones who treat the transaction with the same rigour they’d apply to any other six-figure financial commitment \u2014 because that’s exactly what it is.<\/p>\n Disclaimer:<\/strong> The information provided in this article is for informational purposes only and should not be considered financial or legal advice.
