What Exactly Are Mirror Wills? A Simple Explanation
Mirror wills are two separate wills made by partners—typically spouses or long-term cohabiting couples—that mirror each other’s wishes. They usually include:
- The same executors
- The same beneficiaries
- A mirrored distribution (e.g., everything to the surviving partner, then children)
Mirror wills are popular because they are straightforward and affordable. For a full breakdown of what they include, see our main guide linked above.
When Mirror Wills Are a Good Fit for UK Couples
Mirror wills work well in the following situations:
1. You Share the Same Long-Term Wishes
If you both agree on who should inherit your estate—usually your children or grandchildren—mirror wills provide a simple solution.
2. Most Assets Are Jointly Owned
Joint property, joint savings and shared financial arrangements often make a mirrored approach practical.
3. You Want a Straightforward and Low-Cost Will
Mirror wills are generally quicker and cheaper for solicitors to prepare, making them a convenient choice for uncomplicated estates.

Mirror Wills vs Mutual Wills: What’s the Difference?
These are often confused, but they’re not the same:
- Mirror Wills: Similar in structure, not legally binding.
- Mutual Wills: A binding agreement preventing changes after one partner dies.
Mutual wills can protect beneficiaries, but they are rigid and should only be used with legal advice.
Better Alternatives to Mirror Wills for Modern Families
For blended families or more complex estates, trust-based wills may offer better protection than mirror wills. These include:
- Life Interest & Property Trusts – ideal for protecting property for children and ensuring your share passes to your chosen beneficiaries.
- Family Trusts (Including Discretionary Trusts) – suited for complex arrangements, vulnerable beneficiaries, and greater flexibility in how assets are managed.
- Asset Trusts & Inheritance Tax Planning – useful for safeguarding assets, reducing inheritance tax exposure, and maintaining control over how wealth is passed on.
Key Questions to Ask Before Making Mirror Wills
Before deciding, consider the following:
- Do we agree on long-term beneficiaries?
- Do either of us have children from previous relationships?
- Would we want children protected if one of us remarries?
- Is inheritance tax likely to be an issue?
- Should assets be protected with a trust?
- Do we own property jointly or as tenants in common?
If any of these concern you, it may be worth exploring alternatives.
