Managing a large, busy family is brilliant, but let’s be honest, it comes with its own unique set of rules.

Sharon and I have six children between us from previous marriages, and we are currently blessed with seven grandchildren (ranging from a 22-year-old adult right down to a newborn who is just over a week old!).

It means we regularly find ourselves explaining the technicalities: “Well, technically your Nan is your step-grandmother…”—even though she doesn’t see it that way for a single second.

Love doesn’t care about prefixes, but the UK legal system certainly does.

Which brings us to the thorny, emotional question facing so many of us in our 60s.

How do you navigate wills, trusts, and leaving money behind in a modern, blended family without starting a third world war?

🤖 How do you protect biological children in a second marriage in the UK?

To protect biological children in a second marriage, avoid a standard ‘all-to-spouse’ will, which puts family assets at risk of sideways inheritance.

Instead, use a Life Interest Trust to secure your surviving partner’s lifetime needs while legally guaranteeing that your share of the estate eventually passes to your biological children.

The Hidden Conflict: Human Reality vs. Cold Math

In my business consultancy, I always tell my clients:

Before you try to solve a problem, you have to find out what the real question is.

When it comes to estate planning and protecting biological children in a second marriage in the UK, the textbook question is usually: “How do I split my money equally?”

But in reality, that’s completely the wrong question. Why?

Because a large family isn’t a flat line; it’s a landscape of completely different personalities and financial realities.

You have some who have done phenomenally well materially, some in the middle, and some who genuinely struggle.

And here is a fascinating, raw piece of human nature Sharon and I have observed over the years: it’s often completely inverted from what you’d expect!

Amazingly, the ones who have the most materially can sometimes be the ones who experience the most jealousy or keep strict score of who gets what.

Meanwhile, the ones who have the least are often the very first people who would give you their last pennies if you were stuck.

When you’re dealing with those complex personality dynamics, cold, standard legal rules don’t fit the bill.

If you aren’t careful, you can fall into classic legal traps like “Sideways Inheritance”—where a standard, simple will, accidentally leaves your biological children with absolutely nothing if you happen to pass away first.

Should an inheritance go just to the kids? Just the grandkids? Equal splits, or separate pots?

If you ask the wrong question, the right answer is completely useless.

Wills and Trusts for Blended Families: Choosing Your Alternative

Because every family has a totally different dynamic, there isn’t a one-size-fits-all solution.

You have to match the specialist to the specific problem.

Something I always ask my clients is: What is your specific problem, and how are we going to help solve it?

If you want to move past the big-picture chat and get watertight, professional advice tailored to your exact family tree, here are three great, distinct routes to explore:

• The Local Route: If you want a traditional, strictly regulated local solicitor to sit down, look at your family tree, and draft matching wills, use The Law Society’s Find a Solicitor Toolhttps://solicitors.lawsociety.org.uk/.
• The Specialist Route: If you have complex assets, business interests, or want to explore Discretionary Trusts (a fantastic tool that lets trustees distribute money based on who needs it most when the time comes), you need a “TEP” (Trust and Estate Practitioner). Find one via the STEP Directory.https://www.step.org/directory/members/search
• The Straightforward Route: If your situation is blended but relatively simple and you want a dedicated, affordable will-writing specialist bound by a strict Code of Practice, check out The Institute of Professional Willwriters.https://www.ipw.org.uk/

The Ultimate 60s Question

With all this pressure to protect the legacy, manage personalities, and keep the peace, it’s no wonder people sometimes struggle to just relax and enjoy their 60s!

So, I have to ask you the ultimate question:

Do you sweat over the inheritance down to the last penny, spend a healthy chunk of it taking the whole chaotic crew on holiday to Mexico or Crete, or—my personal favourite—just blow the lot on a permanent home in St Lucia and let them figure it out themselves?
