Planning your will isn’t just about deciding who receives your belongings—it’s about safeguarding your family’s future, avoiding conflict, and ensuring your legacy ends up exactly where you want it to be.
Whether you’re single, part of a couple, or have a blended family, choosing the right type of will can make all the difference. See why proper will planning prevents disputes
Single, Mirror, and Life Interest Wills each serve distinct purposes, offering different levels of flexibility, control, and protection. Understanding how they work helps you make confident decisions that protect your loved ones long after you’re gone.
What Exactly Is a Single Will, and When Should You Choose One ?
A Single Will is the most straightforward type of will—designed for one individual who wants to outline personal wishes for their estate.
It allows you to clearly state:
- Who should inherit your assets
- Who should care for your children
- Who should act as your executor
- How debts, property, and belongings should be handled
When is a Single Will ideal?
- You are unmarried, single, or not sharing assets with your partner.
- You want complete independence over your estate planning.
- Your situation is simple, with minimal shared property or financial ties.
- You want to ensure guardianship for children without involving another parent’s estate.
A Single Will gives you full control and prevents assumptions about who should inherit—ensuring your wishes are respected.
How Does a Mirror Will Work for Couples Who Want Identical Wishes?
A Mirror Will is a pair of wills created by two people—usually partners or spouses—who share the same wishes.
They “mirror” each other, meaning both wills typically leave:
- Everything to each other first
- The remainder to chosen beneficiaries (often children)
Why couples choose Mirror Wills:
- They are simple, cost-effective, and easy to understand.
- Ideal for couples who have joint assets, children together, or aligned intentions.
- They provide reassurance that if one partner passes away, the other is fully protected.
But here’s the catch:
Mirror Wills are not legally binding on the surviving partner. After one partner dies, the other can technically change their will—intentionally or under someone else’s influence.
This can put children from previous relationships at risk.
If long-term protection is important, a Life Interest Will may offer stronger safeguards.
When Is a Life Interest Will the Safest Option for Protecting Assets?
A Life Interest Will includes a Life Interest Trust, which is designed to protect your assets—especially property—while still providing for your partner. How Mirror Wills work for partners
How it works:
- Your partner can live in your property or benefit from your assets for the rest of their life (the “life tenant”).
- They cannot sell, give away, or redirect these assets.
- When they pass away or move into permanent care, your estate passes to your chosen beneficiaries—often your own children.
When you should choose a Life Interest Will:
- You’re in a blended family with children from previous relationships.
- You want to protect your property from being redirected after your death.
- You want to prevent your home from being sold to pay for someone else’s care.
- You want both your partner and your children to be protected at different stages.
Life Interest Wills provide one of the strongest layers of protection for your legacy—giving your partner security without risking your children’s inheritance.
Can These Different Will Types Prevent Family Disputes or Challenges?
Absolutely—and this is one of their greatest benefits.
Choosing the correct will type can:
- Reduce emotional conflict by providing clear instructions
- Minimise the risk of legal disputes after your death
- Stop individuals from challenging inheritance
- Avoid confusion around shared property
- Provide clarity for children from previous relationships
How each will helps prevent disputes:
- Single Wills establish firm, independent decisions—ideal when relationships are complicated.
- Mirror Wills ensure couples share unified wishes, reducing misunderstandings.
Life Interest Wills prevent partners or new spouses from cutting children out of inheritance, safeguarding family harmony.
By making your intentions clear, you leave your family with certainty—not unanswered questions.
How Do Single, Mirror, and Life Interest Wills Handle Property Distribution?
Property often becomes the most sensitive asset in a person’s estate, so how each will treats it matters. Get expert advice on choosing the right will
Single Will
You choose who receives property outright—no conditions.
Mirror Will
Typically, property passes to the surviving partner first, then to children or other beneficiaries. However, the surviving partner can later change their will, which might redirect the property. Why It Is Important To Make A Will?
Life Interest Will
Your partner can stay in the property or receive income from it, but they do not own it outright.
Once they pass away or move into care, the property automatically passes to your chosen beneficiaries.
Why this matters:
- Protecting property from remarriage
- Preventing unintentional disinheritance
- Ensuring children always receive what was meant for them
- Avoiding disputes over shared or blended family homes
Life Interest Wills provide the strictest protection, followed by Single Wills, and lastly Mirror Wills.
Which Will Type Offers the Best Protection for Children From Previous Relationships?
This is one of the biggest concerns for blended or separated families:
“How do I make sure my children still inherit, even if I pass away first?”
Best protection: Life Interest Will
A Life Interest Will ensures your partner is looked after—but prevents them from redirecting your assets elsewhere. Your children remain the final beneficiaries no matter what happens. Arrange a consultation for estate planning
Moderate protection: Single Will
A Single Will allows you complete control, but if you own a home or assets jointly, it may not be enough to secure your children’s inheritance alone.
Least protection: Mirror Will
Mirror Wills work well for simple family situations, but they leave children from previous relationships vulnerable because the surviving partner can rewrite their will after your death.
FAQs: Single, Mirror & Life Interest Wills
Q: Can I switch from a Single Will to a Life Interest Will later if my family situation changes?
Yes, you can change your will at any time. Many people upgrade to a Life Interest Will when entering a new relationship or blending families to better protect children and property.
Q: Do Mirror Wills automatically cancel if one partner passes away or remarries?
No. A Mirror Will remains valid after one partner’s death. However, the surviving partner can still change their own will unless a trust-based will is used instead.
Q: What happens to my home if I have a Life Interest Will and my partner moves into long-term care?
The life interest typically ends when your partner enters permanent care, meaning the property or the share you owned can then pass directly to your chosen beneficiaries.
Q: Can I include conditions like age limits or behaviour rules in any of these will types?
Yes. All three will types allow you to set conditions—for example, children only inheriting after turning 25 or receiving funds in stages.
Q: How are Life Interest Wills treated if the property is jointly owned with my partner?
If the home is owned as tenants in common, your share can go into the Life Interest Trust. If it’s joint tenancy, it must be changed first so your share can be directed into the trust.
Q: Will a Life Interest Will stop a new spouse from inheriting my property after I die?
Yes. Because the trust ring-fences your assets, a new spouse cannot inherit them or change their destination—your beneficiaries remain protected.
