    Blended families — where one or both partners have children from previous relationships — face unique estate planning challenges. Without careful planning, your children from a previous relationship could be left with nothing.

    In 2026, approximately 1 in 3 families in England and Wales are blended families. Despite this, many don't have estate plans that adequately protect all family members.

    The most common concern is the 'sideways disinheritance' problem. If you leave everything to your current spouse, they may later change their Will to benefit only their own children, cutting your children out entirely.

    A Property Trust Will can solve this. It allows your spouse to live in the family home for their lifetime while protecting your share for your children. When your spouse no longer needs the property, your share passes to your children as you intended.

    Life interest trusts are another option. These provide your spouse with income or the use of assets during their lifetime, with the underlying capital eventually passing to your children.

    It's also important to review any financial orders from divorce proceedings, as these may affect what you can do with your estate. Some orders include provisions that survive death.
