The Complex Realities of Estate Planning for Cohabiting Couples in England and Wales

In England and Wales, cohabiting couples are the fastest-growing family type. Despite this, the legal and financial protections available to them remain significantly limited. When it comes to estate planning, the stakes are particularly high. Unlike married couples or civil partners, cohabiting partners have no automatic legal rights to each other’s estate upon death. This leaves many vulnerable to significant financial hardship, potential homelessness, and burdensome tax implications.

This blog explores the key complexities of estate planning for cohabiting couples, the risks to surviving partners and children, and why proactive planning is absolutely essential.

1. No Automatic Inheritance Rights Cohabiting partners do not inherit automatically if their partner dies without a valid Will. Under the rules of intestacy in England and Wales, only spouses, civil partners, and blood relatives are entitled to inherit. This means:

• A surviving cohabiting partner may receive nothing.
• The deceased’s estate could pass entirely to children, parents, or siblings, leaving the partner with no support.

Example: > Jane and Mark lived together for 15 years and had two children. Mark passed away suddenly without a Will. Under intestacy rules, Jane inherited nothing. The entire estate was divided between their children, who were still minors. Jane was forced to apply to the court for financial provision, an uncertain and stressful process.

2. Potential for the Surviving Partner to Become Homeless If the family home is solely in the deceased’s name and no Will is in place, the surviving partner may have no legal right to remain in the property. Even if children inherit the property, the surviving partner could face:

• Eviction or forced sale of the home.
• Costly legal battles to claim a right to remain under the Inheritance (Provision for Family and Dependants) Act 1975.

3. Tax Implications: No Spousal Exemption Unlike married couples, cohabiting partners do not benefit from the spousal exemption for Inheritance Tax (IHT). This can have major consequences:

• Inheritance Tax is charged at 40% on the value of the estate above the threshold (currently £325,000).
• Married couples can transfer unused nil-rate bands to their partner, potentially shielding up to £1 million of the estate. Cohabiting couples cannot.

Result: The estate may pay IHT on both the first and second death, drastically reducing what children or dependants ultimately receive.

4. Children at Risk of Losing Their Inheritance Even if one partner tries to “do the right thing” by leaving everything to the surviving partner, there is no legal guarantee that the children will eventually benefit. The surviving partner can:

• Spend or gift the inheritance.
• Change their Will and exclude the children of the deceased.

This risk increases in blended families or where the surviving partner remarries or forms new relationships.

5. Cohabitation Myths Persist Many people still believe in the concept of a “common-law spouse” — but this status does not exist under English and Welsh law. Without formal legal documents (such as a Will, cohabitation agreement, or trust), a surviving partner has no enforceable rights.

What Can Cohabiting Couples Do to Protect Themselves?

• Make a Will: Each partner should create a Will clearly outlining who inherits what.
• Own Property Jointly: Consider owning the home as “joint tenants” to ensure it passes automatically to the survivor.
• Nominate Pension and Life Insurance Beneficiaries: Ensure policies name your partner explicitly.
• Establish a Cohabitation Agreement: This can define rights and responsibilities during life and after death.
• Use Trusts to Protect Children: A life interest trust can protect a partner’s right to remain in the home while preserving assets for children.
• Get Professional advice: Estate planning is highly technical. Engaging a professional with experience in cohabitation and inheritance law is highly recommended.

Conclusion: For cohabiting couples in England and Wales, estate planning is not a luxury — it’s a necessity. The law does not assume fairness, and without deliberate action, the surviving partner and children can suffer financially and emotionally.

Don’t leave it to chance. If you live with your partner but aren’t married, take proactive steps now to ensure your loved ones are protected, your wishes are respected, and your legacy is secure.
