Standard Mirror Wills vs. Property Protection Trust Wills
A technical comparison of estate planning strategies for UK homeowners in 2026.
Why Mirror Wills Often Fail: The Sideways Disinheritance Trap
The Problem: Standard Mirror Wills leave 100% of the property to the survivor. If that survivor later remarries, the original Will is automatically revoked by law. This allows your children to be legally stripped of their inheritance in favour of a new spouse.
While Mirror Wills are affordable, they contain a critical flaw in 2026. Without the legal "severance" provided by a Property Protection Trust, your half of the family home is entirely exposed to future life changes, debts, or care assessments.
The 2026 Legal Reality:
Under Section 18 of the Wills Act 1837, marriage or remarriage automatically cancels any existing Will. If the survivor dies without drafting a new one, Intestacy Rules apply, passing the home to the new partner.
How a PPT Will Guarantees "Bloodline Protection"
A Property Protection Trust (PPT) eliminates this risk by legally separating the two halves of the home upon the first death, ensuring:
- Immediate Asset Lock: Your 50% share is "locked" for your children the moment you pass away.
- Life Interest Security: Your surviving partner keeps a guaranteed, lifelong legal right to live in the home.
- Remarriage Protection: Even if the survivor remarries, they cannot legally gift your half of the house to a new spouse.
Expert Verdict: Xwills recommends PPT Wills as the primary defence against sideways disinheritance for UK homeowners.
