How to Include Unmarried Partners in Estate Planning

Living together outside marriage or civil partnership brings emotional and practical considerations, but it does not bring automatic inheritance rights under the law in England and Wales. Cohabiting couples who do not take proactive steps in their estate planning risk leaving their partner without legal protection or financial security on death. This article explains the legal position, the tools you can use to include an unmarried partner in your estate plan, and the practical steps to take to protect both partners' interests.

1. The Legal Issue

In the UK, the legal system treats married couples and civil partners differently from unmarried (cohabiting) couples. While a spouse or civil partner has clear statutory rights when their partner dies, unmarried partners have no automatic entitlement to inherit under the rules of intestacy or by default under probate law, regardless of the length of the relationship. Contrary to the popular notion of a “common‑law marriage”, cohabiting in England and Wales does not create recognised inheritance rights.

Estate planning helps you record your wishes about how your assets should be distributed. For unmarried couples, thoughtful planning is essential to ensure one partner is not left without support or forced into legal claims.

2. Inheritance and Intestacy Rules for Unmarried Partners

2.1 No Automatic Inheritance Without a Will

If a person dies without a valid will (intestate), the law in England and Wales sets out a strict order of who inherits. This list includes spouses and civil partners first, then children, parents, siblings and other blood relatives. Unmarried partners are not on this list at all, even if they lived together for decades or shared children.

In practical terms:

• If the deceased owned property in their sole name, their partner may receive nothing.
• Bank accounts, savings and possessions may pass to relatives, not to the cohabiting partner.
• The surviving partner may even lose the home if it is not in joint names or properly protected.

2.2 Jointly Owned Assets

Where property or other assets (such as bank accounts) are owned jointly as joint tenants, those assets can pass automatically to the surviving partner on death by survivorship. However, this does not apply to assets held as tenants in common unless there is a will directing that.

Joint ownership helps with certain assets, but it does not provide a complete solution for inheritance or wider estate planning.

3. Making a Will: The Most Important Step

3.1 Why You Need a Will

A will is the core document of estate planning. For unmarried partners, a valid will is the only reliable way to:

• Nominate your partner as a beneficiary of your estate.
• Ensure they inherit specific assets, such as the home, savings, or personal belongings.
• Appoint your partner as your executor to administer your estate.
• Include other plans, such as trusts, to protect your partner's interests over time.

Without a will, intestacy rules prevail and an unmarried partner can be excluded entirely.

3.2 What a Valid Will Must Include

For a will to be legally valid in England and Wales, it generally must be:

• In writing.
• Signed by the person making the will (the testator).
• Witnessed by two independent adults who also sign in the presence of the testator.

These formal requirements are set out in statute and failing to comply can invalidate the will.

A solicitor can help ensure that a will is properly drafted and reflects your intentions clearly, reducing the likelihood of disputes.

4. Additional Planning Tools for Unmarried Couples

4.1 Inheritance (Provision for Family and Dependants) Act 1975

If an unmarried partner is left with little or nothing after their partner dies, there may be a legal route to seek financial provision from the estate under the Inheritance (Provision for Family and Dependants) Act 1975 (“the 1975 Act”).

Under this law:

• A cohabiting partner may apply to the court for “reasonable financial provision” from the estate.
• Eligibility usually requires that the couple were living together as if married or in a civil partnership for at least two years immediately before death, although financial dependence can also be relevant.
• The court decides what is reasonable in all the circumstances, taking into account the needs of the applicant and the size of the estate.

This is a court process and outcomes depend on the facts of each case. It does not provide automatic inheritance rights but can be a remedy in cases of hardship.

4.2 Cohabitation Agreements

A cohabitation agreement (sometimes called a living‑together agreement) is a private contract between partners that sets out arrangements for property, finances and other matters if the relationship ends or one partner dies.

Although not strictly binding like a marriage contract, a well‑drafted cohabitation agreement can:

• Clarify ownership shares in property and investments.
• Provide evidence of the parties' intentions, which can be useful in legal disputes.
• Complement a will or other estate planning documents.

Free legal advice should be obtained before entering into such an agreement to ensure both parties understand its implications.

4.3 Beneficiary Designations

Some assets pass outside of a will:

• Pension death benefits can be paid to a nominated beneficiary.
• Life insurance policies usually pay to named beneficiaries directly.
• Workplace death‑in‑service benefits may also be paid to beneficiaries.

Ensuring your partner is named as the beneficiary on these instruments can provide immediate financial support without going through probate.

4.4 Lasting Powers of Attorney

A lasting power of attorney (LPA) allows you to appoint someone to make decisions about your property, finances or health if you lose capacity. Unmarried partners do not automatically have these rights, so creating LPAs can protect your partner's ability to act on your behalf.

5. Tax Considerations for Unmarried Partners

Unmarried partners do not benefit from the same inheritance tax exemptions as spouses and civil partners. Transfers between spouses are generally exempt from inheritance tax, and unused allowances can be transferred between them. Cohabiting partners do not receive these exemptions.

This means:

• Gifts to your partner may result in an inheritance tax liability if your estate exceeds the nil‑rate band (currently £325,000).
• Pensions and other assets may be brought into the estate in the future under new tax rules.

Tax planning in conjunction with wills and beneficiary nominations should be considered as part of a comprehensive strategy.

6. Practical Steps to Protect Your Unmarried Partner

6.1 Create or Update Your Will

Ensure your will reflects your current circumstances, names your partner as a beneficiary, and sets out your intentions clearly.

6.2 Check Ownership of Property and Assets

Decide whether joint ownership or trust arrangements are appropriate. If property is owned as tenants in common, consider a declaration of trust to reflect each partner's share.

6.3 Review Beneficiary Nominations

Update pension nominations and life insurance policies so your partner is a designated recipient.

6.4 Consider a Cohabitation Agreement

This can help clarify financial and property arrangements and support other estate planning documents.

6.5 Plan for Tax

Understand how inheritance tax rules apply to your situation and whether gifting or other tax planning steps are advisable.

6.6 Seek Professional Advice

Solicitors specialising in wills and estate planning can help structure your plan to achieve your goals and reduce the risk of disputes.

7. Common Questions

Can my partner inherit without a will?
No. Unmarried partners are not included in intestacy rules and must be named in a will or receive assets by other mechanisms such as joint ownership.

What is a claim under the Inheritance Act?
It is a court application where an unmarried partner seeks reasonable financial provision from an estate where they have been left out or inadequately provided for.

Do we need to live together for a certain time to make a claim?
Yes, cohabitation of at least two years immediately before the death is usually required for claims under the 1975 Act, though financial dependence may also be sufficient.

Does joint property ownership protect my partner?
Yes, if property is owned as joint tenants, it passes automatically to the surviving partner. However, this addresses the property but not other assets or liabilities.

8. Summary

Unmarried partners in England and Wales have no automatic legal right to inherit under intestacy or probate law. To include your partner in estate planning you should:

• Make a valid will that names them as a beneficiary.
• Consider joint ownership of key assets.
• Use tools such as the Inheritance Act 1975, cohabitation agreements, beneficiary nominations, and lasting powers of attorney.
• Integrate tax planning and regularly review your arrangements with professional guidance.

Taking these steps helps protect your partner's financial security and ensures your wishes are respected.
