Family money is now a normal part of buying a home. Parents help. Grandparents help. Sometimes the money comes from savings, sometimes from inheritance, sometimes from their own property wealth, and sometimes from people stretching themselves because they want to help the next generation get on the ladder.
Legal & General’s Bank of Family research says gifting from parents and grandparents is expected to reach £11.3bn in 2026, with parents and grandparents gifting £27,400 on average. Savills has also reported that 53% of first-time buyers received some form of family support in 2025, with family support accounting for £11bn of first-time buyer housing equity when inheritance is included.
So, for mortgage brokers, gifted deposits are not unusual anymore. In fact, they’re part of the job. The lender needs to know where the money has come from, the gift letter is signed, the person giving the money confirms it is not a loan, and the case moves forward.
In mortgage terms, that may be enough.
The deposit has been explained, the lender is happy, and everyone can get on with trying to complete the purchase.
Except there is another question sitting behind some of those gifts. And it’s a question that may matter much longer than the mortgage itself.
What was the money really meant to do?
Say parents gift money to their daughter and her husband so they can buy a home.
At the time, everyone knows why the money is being given. It’s to help them buy somewhere secure. It may also be, in the parents’ minds, a way of helping their daughter and any grandchildren build something for the future.
Nobody is thinking badly of anyone. Nobody is planning for remarriage, family arguments, or children being missed later on. They’re just helping.
But what happens if their daughter dies first?
That is where the original intention can start drifting away from the eventual outcome.
If the home passes fully to her husband, either because of the way the property is owned or because of how the Will is written, that family money may now sit entirely in his estate.
If he later remarries, changes his Will, has more children, or leaves everything to a new spouse, the value that came from her side of the family could eventually pass somewhere nobody expected.
Her children may not benefit from it in the way her parents assumed they would. And nobody has to behave badly for that to happen.
Someone dies, life carries on, years pass, people meet new partners, families change, and the paperwork follows the route it was given.
The broker may see the warning sign first
This is where a mortgage conversation can become an estate planning conversation.
The broker does not need to give legal advice, but brokers are often the first professional to see the trigger.
They see that the deposit is coming from one side of the family. They hear that Mum and Dad are helping. They hear that one buyer is putting in more than the other, or that the couple are not married, or that this is a second relationship, or that there are children from previous relationships.
And while the gifted deposit answers the lender’s question the family might still be left asking, “Who is this money meant to benefit if life does not go in the order everyone expects?”
And once you ask that, the property itself starts to matter too.
One ownership detail can change the outcome
Property ownership is often misunderstood.
GOV.UK explains that joint owners can own property as joint tenants or tenants in common, and that people may change from joint tenants to tenants in common if, for example, they want to leave their share of the property to someone else.
HMRC’s guidance also explains that when someone owns as tenants in common, their share does not automatically pass to the surviving owner when they die.
That difference can be important.
If a property passes automatically to the survivor, the Will may not deal with that part of the estate in the way the client thinks it does.
If a share is owned separately and planned for properly, there may be more scope to protect where that value should ultimately go.
Clients need to understand what they have chosen, and whether it matches what they think will happen.
Because assumptions tend to survive right up until the paperwork proves otherwise.
Blended families make the question harder
STEP research found that conflict between children or stepchildren and a surviving parent or stepparent was the most common source of friction in inheritance disputes, cited by 68% of practitioners.
That will not surprise many people who work with families. Children may remember where the deposit came from. The surviving spouse may see the home as theirs. Stepchildren may have a different view again.
And if nobody has written things down properly, everyone is left trying to work out what was meant and usually at the worst possible time.
As a mortgage broker, you don’t have to ask a heavy questions and it does not have to derail the mortgage conversation.
It can be as simple as: “If family money is going into the property, have you taken advice on how that money should be protected if one of you dies?”
Another version might be: “It may be worth checking whether your Will and the way you own the property reflect what you want to happen to that money later.”
That’s it, plain and simple. Some clients will already have it covered. Some will know exactly how the property is owned and why but others will pause and stare at each other because they have never thought about it before.
That pause is really useful to you and it’s often the first sign that the mortgage transaction has uncovered a much bigger family question.
The decisions that cause trouble rarely feel risky at the time
That is the hard thing with estate planning because problems often start with decisions that looked perfectly sensible at the time.
Family helping family. A gift letter for the lender. A couple trusting each other. A house purchase everyone just wants to get finished.
Nothing about it feels dangerous then years later, after a death, the question becomes much harder.
A gifted deposit can help someone buy a home, and that is a good thing, but that money may have a much longer life than the mortgage application.
And if the planning around it is missing, the same gift can end up somewhere nobody intended.
At Secure Inheritance, we help clients understand how their Wills, property ownership and wider estate planning work together, and we support mortgage brokers who want to raise these questions carefully without stepping outside their role.
Because “we all know what we mean” is fine around the kitchen table but it’s not always enough when the paperwork has to speak for everyone later.
