Mirror Wills
What Are Mirror Wills and How Do They Work?
Mirror wills are one of the most popular types of wills for married couples and civil partners. They allow two people to create separate but almost identical wills that reflect each other's wishes, making estate planning simpler while ensuring each person's wishes are legally documented.
For many couples, mirror wills provide peace of mind by ensuring that the surviving partner is protected and that children or other beneficiaries inherit the estate after both people have died.
This guide explains how mirror wills work, their benefits, potential drawbacks and whether they're the right choice for your circumstances.
What Are Mirror Wills?
Mirror wills are two separate legal wills that contain very similar or identical instructions. Although they “mirror” one another, each will remains an independent legal document.
A typical mirror will provides that:
- Everything passes to the surviving spouse or civil partner after the first death.
- After the surviving partner dies, the estate passes to the children or other chosen beneficiaries.
- Each person appoints the same executors.
- Each person names the same substitute beneficiaries.
Despite being almost identical, each individual owns and signs their own will. GOV.UK’s overview of making a will covers the general legal requirements that apply to any will, mirror or otherwise.
Who Should Consider Mirror Wills?
Mirror wills are commonly chosen by married couples, civil partners, long-term partners with similar wishes, couples with children, homeowners, and couples who own most assets jointly.
They are particularly useful when both partners want their estate to be distributed in the same way.
How Do Mirror Wills Work?
Step 1: Both Partners Prepare Their Wills — each person prepares an individual will, usually with almost identical wording.
Step 2: Executors Are Appointed — most couples appoint each other, adult children, other trusted family members, or professional executors if appropriate, with replacement executors often named as a backup.
Step 3: Beneficiaries Are Chosen — typically the surviving partner inherits first and children inherit after both parents have died, though couples can customise this.
Step 4: Each Will Is Signed Separately — even though the content is similar, each will must be signed individually, witnessed correctly, and meet the legal requirements for a valid will.
Advantages of Mirror Wills
Simplicity — both partners can make their wills at the same time using similar instructions.
Lower Cost — preparing mirror wills together is often more cost-effective than preparing two completely separate wills.
Consistency — both wills reflect the couple’s shared wishes, helping reduce confusion.
Protection for the Surviving Partner — in many cases, the surviving spouse or civil partner inherits the estate before assets pass to the next generation.
Easier Estate Administration — using similar wills can simplify Probate because the intentions of both individuals are clearly documented.
Potential Disadvantages
Mirror wills are not suitable for everyone. Potential drawbacks include:
- Family circumstances may change over time.
- Children from previous relationships may require different arrangements.
- Tax planning may become more complex.
- One partner may later wish to change their will.
It’s important to review mirror wills regularly to ensure they continue to reflect your wishes.
Can Mirror Wills Be Changed?
Yes. While both partners are alive and have mental capacity, each person can generally change or replace their own will. For example, changes may be needed after the birth of a child, a divorce, purchasing property, receiving an inheritance, changes in financial circumstances, or the death of a beneficiary or executor.
Mirror Wills vs Joint Wills
Mirror wills and joint wills are often confused, but they are different. For most couples, mirror wills are the preferred option because they offer greater flexibility.
Mirror Wills and Blended Families
Couples with children from previous relationships should consider whether mirror wills fully meet their needs. Additional planning may be appropriate if you wish to protect children from a previous relationship, preserve family assets, provide for a surviving partner while safeguarding part of the estate, or create trusts for young or vulnerable beneficiaries. Professional legal advice can be particularly valuable in these situations.
When Should You Review Mirror Wills?
It’s sensible to review your wills every few years and after major life events, including marriage or civil partnership, divorce or separation, birth or adoption of children, death of an executor or beneficiary, buying or selling property, or significant changes in wealth.
Common Mistakes to Avoid
When preparing mirror wills, avoid assuming they can never be changed, forgetting to review them after major life events, failing to appoint replacement executors, using unclear wording, storing the original wills separately without telling your executors where they are kept, and assuming mirror wills are suitable for every family situation.
