Helping your children buy a home overseas: how to gift the money without holding up their purchase

A parent offers to help their child buy a home in Spain. The money is sitting in a UK savings account, the property has been found and everyone agrees on the amount. Surely all that’s left is to send it?

Not quite. That apparently simple family gift could face questions from banks, lawyers, mortgage lenders and the authorities in the country where the property is being bought. And if those questions aren’t answered before the deposit or completion payment falls due, the money may not arrive in time.

It’s an easily overlooked complication of helping the next generation onto the property ladder, particularly when that ladder happens to be in another country.

The issue isn’t whether parents are allowed to give their children money. Generally, they can. It’s whether the people handling the property purchase are satisfied about where that money came from, who owns it and what the arrangement means for the buyer.

When a family gift raises questions

Anti-money-laundering checks are an unavoidable part of international property transactions, but their implications for family gifts are not always obvious.

In guidance published in July 2026, HM Revenue & Customs specifically identified gifted funds as an area where businesses may need supporting evidence. It isn’t necessarily enough to show that £100,000 has arrived in somebody’s bank account. The institution handling the transaction may also need to establish how the original owner accumulated that money.

For a parent using long-held savings, that might involve bank statements showing regular income and the accumulation of funds. If the money came from selling a business, property or investment portfolio, the evidence could be quite different.

The distinction is between proving that the money exists and establishing where it came from. A bank statement can help with the first question without necessarily answering the second.

As Smart Currency Exchange explains in its article on source-of-funds checks and anti-money-laundering delays, the paperwork required for a large international transfer depends on how the money was originally obtained.

There’s another complication. The parent’s contribution introduces a third party into the funding of the child’s property purchase.

That doesn’t automatically make it unacceptable. However, HMRC’s guidance to UK estate agents specifically highlights gifted deposits and last-minute changes in funding arrangements as matters requiring attention.

Overseas professionals will apply the rules relevant to their own jurisdictions, which may differ from those in Britain.

The family relationship explains why the money is being given. It doesn’t remove the need to document the transaction.

A gift or a loan? The distinction matters

Parents may think little of telling their children they can pay the money back if circumstances allow. Within the family, that might seem a reasonable arrangement.

To a mortgage lender, however, it can make a substantial difference.

A genuine gift generally means the money is given without an obligation to repay it. If repayment is expected, even informally, the contribution may need to be treated as a loan when the lender assesses the buyer’s finances.

That is why a lender or legal representative may ask for a signed declaration explaining the arrangement. The wording and form required will depend on the country and the particular mortgage or purchase.

This is one of several complications covered in our look at overseas mortgages and what UK buyers need to know. The lender’s assessment of the deposit is separate from the checks carried out by the institutions transferring the money.

The same principle applies to parents who expect to retain a financial interest in the property. Giving money towards a purchase isn’t necessarily the same as becoming a part-owner.

Indeed, buying a holiday home with family or friends creates a different set of questions about ownership, responsibilities and what happens if somebody wants to sell.

These are matters to settle with the buyer’s lawyer and mortgage provider before sending the money, not after somebody questions the payment.

The documentation doesn’t have to be complicated in every case. But the explanation must reflect what the family has actually agreed.

Crossing borders brings another set of rules

There is also the question of tax, and this is where the country involved can make a substantial difference.

In the UK, parents can make gifts exceeding the familiar £3,000 annual Inheritance Tax exemption. Larger outright gifts will often fall outside the donor’s estate if they survive for seven years, although the rules contain important qualifications.

As HMRC’s rules on giving gifts make clear, the £3,000 figure is not a ceiling on what parents can give, nor does exceeding it automatically trigger an immediate tax bill.

But the UK’s treatment of the gift is only part of the picture.

France, for example, requires monetary gifts falling within its tax rules to be declared, even where an exemption means no tax is payable.

Since 1 January 2026, most declarations of these gifts must be made online, rather than on paper. This was a change to the reporting process, not a new tax on family gifts.

French rules also provide a €100,000 parent-to-child gift tax allowance, renewable every 15 years, subject to the applicable conditions and previous gifts. The French tax authority explains the allowances and how they interact with other exemptions.

Spain has its own gift tax system, with the treatment influenced by the recipient’s residence, the assets involved and potentially the rules of an autonomous community.

For certain cross-border monetary gifts falling within Spanish taxation, the Spanish tax authority specifies a Modelo 651 declaration, with a filing deadline of 30 working days.

Crucially, buying property in France or Spain does not, by itself, establish how a separate cash gift will be taxed. The residence of the people involved and the location and nature of the gifted assets also matter.

For parents living in Britain and children established overseas, that is a question worth putting to a suitably qualified cross-border tax adviser before any money changes hands.

The money still has to get there

Even when everyone is satisfied about the gift, the overseas payment itself needs planning.

Consider a parent contributing £100,000 towards a child’s house purchase in Spain. At an illustrative exchange rate of £1 to €1.20, that provides €120,000 before currency provider margins and fees.

If the rate moves to €1.15 before the transfer is made, the same £100,000 provides €115,000.

The parent hasn’t changed their contribution, but the amount available towards the property has fallen by €5,000.

That becomes particularly important when a gift is intended to cover a specific euro-denominated deposit or completion payment rather than a fixed amount in sterling.

Exchange rates can, of course, move in either direction. The problem is not knowing which way they will move, but agreeing a property payment in one currency while the money remains in another.

One option, depending on the family’s circumstances, may be a forward contract, which can fix an exchange rate for an eligible future payment. That provides greater certainty over the cost but removes the opportunity to benefit from a more favourable exchange rate later. Contractual terms and obligations also apply.

Timing matters just as much as the rate.

The sending institution may need to verify the parent’s identity and source of funds. The receiving bank may have further questions. The buyer’s lawyer or notary may also have specific requirements about which account should make the payment.

And international payments aren’t necessarily completed the moment somebody presses send.

The Bank of England has identified differences in payment-system operating hours as one source of friction in cross-border transfers. Compliance checks and the receiving institution’s procedures can add further delays.

What looks like a straightforward transfer on a Wednesday afternoon can therefore become a problem if the money is required for a property transaction on Thursday morning.

One particularly awkward mistake is for the parent to send funds directly to the overseas lawyer or seller when the transaction requires payment from an account belonging to the buyer. That may be perfectly legitimate in some circumstances, but it is not something to assume.

The receiving professional and payment provider should agree the route before the money moves.

This is why preparing funds early forms part of buying overseas in the next 90 days. By the time contracts are signed and completion approaches, the source of the funds, the currency requirement and the payment arrangements should already be understood.

The gift that keeps on giving – paperwork

None of this should discourage parents from helping their children buy overseas. Family funding can make a substantial difference, whether it pays for an entire property or provides the deposit needed to secure a mortgage.

But there are really two transactions taking place: the gift between parent and child and the payment for the overseas property. Both need to be understood, documented and timed.

Getting those arrangements in place before the child commits to a payment deadline is far easier than trying to reconstruct the paperwork when a completion date is approaching.

For the currency element, Smart Currency Exchange can help with international payments to family members, including discussing the destination currency, transfer arrangements and exchange-rate options available.

The legal and tax questions belong with the appropriate qualified professionals.

After all, the point of helping your child buy a home is to make the purchase easier. The last thing anybody wants is for the gift itself to become the reason it is delayed.
