Wills & Estate Planning
Unmarried couples have no automatic inheritance rights in England and Wales. Without a Will, your partner could inherit nothing — regardless of how long you have lived together.
The Common Law Marriage Myth
Common law marriage does not exist in England and Wales. These four misconceptions leave thousands of cohabiting couples dangerously unprotected.
“We have been together for years — we are common law married.”
Common law marriage does not exist in England and Wales. No matter how long you have lived together, cohabiting couples have no automatic legal rights to each other's estate.
“My partner will automatically inherit my estate.”
Under the Rules of Intestacy, an unmarried partner inherits nothing if you die without a Will. Your estate passes to blood relatives — parents, siblings, or children — regardless of your relationship.
“Our joint mortgage means we own the property together.”
A joint mortgage does not determine inheritance. What matters is how the property is legally owned — as joint tenants (right of survivorship) or tenants in common (each owns a defined share, which passes under the Will or intestacy).
“We can sort out the Will later.”
Capacity to make a Will can be lost suddenly — through accident, illness, or dementia. Once capacity is lost, a Will cannot be made. The consequences of dying without a Will as an unmarried couple can be devastating.
Without a Will
If you die without a Will, the Rules of Intestacy determine who inherits your estate. Unmarried partners are not included at any stage.
| Priority | Beneficiary | Notes |
|---|---|---|
| 1st | Children (equally) | If no children, passes to next category |
| 2nd | Parents | If no parents, passes to next category |
| 3rd | Siblings (full blood) | If no siblings, passes to next category |
| 4th | Half-siblings | If none, passes to next category |
| 5th | Grandparents | If none, passes to next category |
| 6th | Aunts and uncles | If none, estate passes to the Crown |
| — | Unmarried partner | NOT included at any stage under intestacy |
Choosing the Right Will
Unmarried couples typically choose between mirror Wills (two separate but complementary documents) and joint Wills (a single document). Mirror Wills are strongly recommended.
| Issue | Mirror Wills ✓ | Joint Will ✗ |
|---|---|---|
| Flexibility | Each partner can update their Will independently | Both partners must agree to any changes |
| After first death | Survivor can update their Will to reflect new circumstances | Survivor may be bound by the original terms |
| Remarriage | Survivor can make a new Will after remarriage | May restrict survivor's ability to provide for new partner |
| Cost | Slightly higher (two separate documents) | Single document — marginally cheaper |
| Recommended for | Most unmarried couples | Rarely recommended — significant disadvantages |
Protecting Your Home
How you own your home has a significant impact on what happens to it when one partner dies. Understanding the difference is essential for unmarried couples.
Both partners own the entire property together. On death, the surviving partner automatically inherits the deceased's share by right of survivorship — regardless of the Will.
Advantages
Disadvantages
IHT note: The full property value is included in the survivor's estate on second death.
Each partner owns a defined share of the property (typically 50/50, but can be any split). Each share passes under the Will — or intestacy if there is no Will.
Advantages
Disadvantages
IHT note: Each partner's share is assessed separately for IHT. Enables nil-rate band planning on first death.
Inheritance Tax
Unmarried couples face a significantly higher inheritance tax burden than married couples. Understanding the differences is the first step to effective planning.
Married couples and civil partners can pass assets of any value to each other completely free of IHT. Unmarried couples do not qualify for this exemption. Assets above £325,000 are taxed at 40%.
Married couples can transfer the unused nil-rate band from the first death to the survivor, effectively doubling the tax-free threshold to £650,000. Unmarried couples cannot do this — each partner has only their own £325,000 allowance.
Each partner has their own £325,000 nil-rate band. Assets below this threshold pass free of IHT. Careful estate planning — including lifetime gifting and trust structures — can help minimise the IHT liability.
The £175,000 residence nil-rate band applies when leaving your main residence to direct descendants. Unmarried couples can each use this allowance — but it cannot be transferred between partners as it can between spouses.
Planning tip: Unmarried couples can reduce their IHT exposure through lifetime gifting (up to £3,000 per year tax-free), life insurance policies written in trust, and careful use of the nil-rate band. Speak to our wills team about a tailored estate plan.
Broader Protection
A Will is essential — but it is only one part of a complete protection plan for unmarried couples. These four additional steps provide comprehensive legal and financial security.
A cohabitation agreement sets out how property, finances, and other assets are owned and what happens if the relationship ends. It provides legal protection during life — complementing the Will's protection after death.
An LPA allows your partner to manage your finances and make healthcare decisions if you lose capacity. Without an LPA, your partner has no legal authority — even if you have lived together for decades.
A life insurance policy written in trust pays out directly to your partner — outside the estate and free of IHT. This provides immediate funds to cover the IHT bill or living expenses without waiting for probate.
Pension death benefits are not governed by the Will — they are paid to whoever is nominated on the Expression of Wish form. Update your nomination to include your partner, or the pension trustees may pay to your estate or blood relatives.
A Will is the most important step an unmarried couple can take to protect each other. Our wills team can advise on mirror Wills, property ownership, and IHT planning tailored to your circumstances.
Common Questions
No. Unmarried couples have no automatic inheritance rights under English law. The common law marriage myth — the belief that long-term cohabiting couples have the same rights as married couples — has no legal basis in England and Wales. Without a valid Will, an unmarried partner inherits nothing under the Rules of Intestacy.
Mirror Wills are two separate Wills made by a couple that mirror each other — typically leaving everything to the surviving partner, then to children or other beneficiaries on the second death. They are the most common and recommended approach for unmarried couples. Unlike joint Wills, each partner can update their mirror Will independently after the first death.
If your partner dies without a Will, their estate is distributed under the Rules of Intestacy. As an unmarried partner, you are not included in the intestacy order at any stage — regardless of how long you have lived together. The estate passes to blood relatives: children first, then parents, then siblings. You could be left with nothing, even if you shared a home.
Possibly. Under the Inheritance (Provision for Family and Dependants) Act 1975, a cohabiting partner who lived with the deceased for at least two years immediately before the death can apply to the court for reasonable financial provision. However, this is a costly and uncertain process — it is far better to make a Will than to rely on a court claim.
For unmarried couples, tenants in common is generally preferable. It allows each partner to leave their share of the property in their Will — enabling Protective Property Trust planning, care fee protection, and nil-rate band planning. Joint tenancy is simpler but offers less flexibility and no protection if the survivor remarries or faces care fees.
Yes. The spousal exemption — which allows assets of any value to pass between spouses free of IHT — does not apply to unmarried couples. Assets above the £325,000 nil-rate band are taxed at 40%. Unmarried couples also cannot transfer the nil-rate band between partners, unlike married couples who can combine their allowances to shelter up to £650,000.
A cohabitation agreement is a legal document that sets out how property, finances, and other assets are owned between cohabiting partners, and what happens if the relationship ends. It provides legal protection during life — complementing the Will's protection after death. It can also address practical matters such as who pays the mortgage, how joint expenses are shared, and what happens to pets.
Yes — if you own the property as tenants in common. You can leave your share to your children in your Will, while granting your partner a life interest (the right to live in the property for life) through a Protective Property Trust. This protects your children's inheritance while ensuring your partner is not forced to leave the family home.
Yes. Pension death benefits are not governed by the Will — they are paid to whoever is nominated on the Expression of Wish form held by the pension provider. If you have not updated your nomination to include your partner, the pension trustees may pay to your estate or to blood relatives. Update your nomination form with every pension provider.
The Inheritance (Provision for Family and Dependants) Act 1975 allows certain people — including cohabiting partners who lived with the deceased for at least two years — to apply to the court for reasonable financial provision from the estate. The court has wide discretion and will consider the applicant's financial needs, the size of the estate, and the deceased's obligations. Claims are costly and uncertain — a Will is always preferable.
