Blended families — where one or both partners have children from previous relationships — face unique estate planning challenges. In 2026, an estimated 1 in 3 UK families are blended, making this one of the most common planning scenarios we encounter.
The biggest risk is the 'sideways disinheritance' problem. If you leave everything to your spouse and they later remarry or change their Will, your children from a previous relationship could lose their inheritance entirely.
A Life Interest Trust (also known as a Right to Occupy Trust) solves this problem. It gives your surviving spouse the right to use your assets (such as living in your home and receiving income from investments) during their lifetime, while preserving the capital for your children.
Another consideration is the intestacy trap. Under the 2026 intestacy rules, stepchildren have no automatic right to inherit from a stepparent. If you die without a Will, your stepchildren — even those you've raised from childhood — receive nothing.
Pension nominations and life insurance beneficiary designations should also be reviewed carefully. These assets pass outside your Will, so they need to be coordinated with your overall estate plan.
Open family communication is important. While it can be uncomfortable, discussing your estate plan with your partner and (where appropriate) your children can prevent misunderstandings and family conflict after your death.
