Blending a family after a second marriage is both joyful and complicated—especially when it comes to inheritance. Without careful planning, your life insurance payout can spark bitter disputes between your new spouse and children from a previous relationship.
A life insurance trust offers a clean, legal solution. It ensures your benefits go exactly where you intend, sidestepping the inheritance battles that so often tear blended families apart. For UK families, this is not just about peace of mind—it’s about preserving relationships and wealth.
If you’re navigating the complexities of a second marriage, understanding how trusts work is essential. And if you want a deeper dive into the strategy, the book Life Insurance Made Simple is a great starting point.
The Blended Family Inheritance Trap
Blended families face unique inheritance risks. When you die, your life insurance policy pays out to your estate or a named beneficiary. If your policy is not written in trust, the money flows into your estate, where it is subject to:
- Probate delays – the family must wait months for funds
- Inheritance Tax (IHT) – anything above £325,000 risks a 40% charge
- Intestacy rules – if no Will exists, the new spouse gets everything, leaving stepchildren with nothing
- Claims under the Inheritance Act 1975 – a disgruntled relative can challenge the Will
In second marriages, the tension is often between a surviving spouse who wants the full payout and children from a first marriage who feel entitled to their parent’s share. This conflict can create lifelong rifts.
What Is a Life Insurance Trust?
A life insurance trust is a legal arrangement where you place your policy into a trust. The trust owns the policy, and upon your death, the payout is controlled by trustees you appoint—not the probate court.
Trustees distribute the money according to your written wishes. In the UK, the most common types for life insurance are:
- Discretionary Trusts – trustees decide who gets what, offering flexibility for changing family circumstances
- Bare Trusts – the payout goes directly to named beneficiaries when they turn 18 (or at a specified age)
For blended families, discretionary trusts are far more effective because they allow trustees to balance the needs of a surviving spouse with those of children from a previous relationship.

How Trusts Protect Against Inheritance Disputes
A trust removes the payout from your estate, so it never becomes part of probate. This delivers several critical protections:
1. Control Over Beneficiaries
You can name your spouse as a potential beneficiary but also leave instructions (known as a letter of wishes) that the trustees should consider your children’s needs. The spouse receives income or support without the capital being wasted.
2. Avoids Delays
Probate can take 6–12 months in the UK. A trust releases funds within weeks, giving your family immediate financial stability.
3. Inheritance Tax Efficiency
Because the trust sits outside your estate, no IHT is payable on the payout (provided the trust is set up correctly). That could save your family tens of thousands of pounds.
4. Protects Against Claims
Trust money is harder to attack under the Inheritance Act. A determined claimant would need to challenge the trust itself, which is far more difficult than contesting a Will.
Example from London: Sarah, 52, remarried and had two adult children from her first marriage. Her new husband has no children. She wrote her £400,000 life policy into a discretionary trust with her solicitor as trustee. Upon her death, the trustees provided her husband with income for life, then divided the remaining capital equally among her children. No disputes arose because everyone’s needs were respected.
Step-by-Step: Setting Up a Trust for Your Second Marriage
Setting up a life insurance trust in the UK is straightforward. Here’s how to do it:
- Step 1: Choose the right type of trust – discretionary for most blended families, bare trust if you want fixed shares after a set age.
- Step 2: Complete a trust deed (your insurer provides one or you can use a solicitor).
- Step 3: Appoint trustees – ideally two or more, such as a close friend, family member, or professional (e.g., accountant or solicitor).
- Step 4: Transfer the policy into the trust – this is called “writing the policy in trust.”
- Step 5: Review your letter of wishes every few years, especially after changes in the family (new grandchildren, divorce, etc.).

Real-World Examples Across the UK
Edinburgh
James, 60, married his second wife Fiona. He had three children from his first marriage. By using a discretionary trust, he ensured Fiona could live in the family home without selling it, while his children inherited the remaining estate. A local Edinburgh solicitor helped tailor the trust to Scottish succession law.
Cardiff
Megan, 45, and her second husband both had children from previous relationships. They set up mirror trusts—each wrote their policies into separate trusts. This gave each parent control over their own children’s inheritance while providing for each other during their lifetimes.
Belfast
Northern Ireland has its own inheritance rules. A retirement planning specialist in Belfast advised the couple to use a whole-of-life policy written in trust to cover future IHT bills on their jointly owned home. This prevented any forced sale after the first death.

Common Mistakes That Can Trigger a 40% Inheritance Tax Charge
Even a well-intentioned trust can fail if you fall into these traps:
| Mistake | Consequence |
|---|---|
| Not reviewing the trust after remarriage | Old beneficiaries miss out; new spouse unprotected |
| Using a bare trust for blended families | Children get full control at 18—may ignore step-parent needs |
| Failing to appoint independent trustees | Conflict of interest if spouse is sole trustee |
The biggest error is leaving the policy outside a trust at all. Without a trust, the payout falls into your estate, and your family could face a 40% Inheritance Tax bill.

Additional Benefits: Covering Inheritance Tax on Your Home
Many UK families need life insurance trusts not just for family harmony but to pay the IHT bill on their property. If your home is jointly owned and your estate exceeds the IHT threshold, a life insurance trust can provide tax-free cash to your beneficiaries exactly when they need it. This is especially useful for second marriages where the family home might be left to a spouse but children want to preserve it.
Our guide Using a Life Insurance Trust to Cover an Inheritance Tax Bill on Your Home walks you through the numbers.
Should You Use Over 50s or Whole-of-Life Policies in a Trust?
For retirees in second marriages, policies like over 50s or whole-of-life can be written in trust, but there are pros and cons. Over 50s plans often pay out less than the total premiums if you die early, while whole-of-life policies guarantee a sum for IHT planning.
