Let’s be honest, most people don’t like talking about death, money, or legal documents. But if you and your partner live together and are not legally married, creating a Will isn’t just a formality – it’s essential for protecting each other’s future. This guide explains why unmarried couples need a Will, how property ownership affects what happens if one partner dies, and what you can do to ensure financial security and peace of mind for both of you.

Do Unmarried Couples Have the Same Rights as Married Couples?

No. That’s the short answer – and the most important one.

There’s a common belief that living together for years makes you “common law” spouses with similar rights to married couples. But in the UK, common law partnerships do not exist in legal terms. If one of you dies without a Will, the rules of intestacy automatically decide how the estate is divided.

And here’s the thing – under those rules, unmarried partners or cohabiting partners have no automatic entitlement to inherit anything from each other’s estate. Everything could go to the next of kin, such as parents, siblings, or children.

According to the Office for National Statistics (ONS), over 3.6 million couples in the UK now live together without being married or in a civil partnership. Yet, only around 26% of cohabiting couples have a valid Will in place. That means millions risk leaving their surviving partner with no legal claim to their home, savings, or possessions.

What Happens If My Partner Dies Without a Will?

If your partner dies without a Will and you’re not married or in a civil partnership, the law treats you as strangers.

Unless you jointly own assets, you’ll have no legal right to inherit anything – not even the home you live in together. The estate will be shared according to intestacy rules, which prioritise blood relatives over partners.

For example:

• If your partner has children, they inherit everything.
• If not, it passes to parents or siblings.
• You, as the surviving partner, may receive nothing unless you jointly own property or can prove financial dependence.

To make matters worse, you could face inheritance tax implications that married couples or civil partners are exempt from. A legally married spouse or civil partner can transfer assets free of inheritance tax, but cohabiting couples cannot.

How Can a Will Protect Unmarried Couples?

A valid Will is the simplest and most effective way to make sure your surviving partner is taken care of. By naming them as a beneficiary, you control exactly how your estate plan unfolds.

Creating a Will allows you to:

• Secure your partner’s home and living arrangements
• Make financial provision for them and any dependents
• Reduce family disputes and stress after death
• Potentially reduce the amount of inheritance tax due on your estate

It also provides clarity to your family members, helping to avoid confusion or tension between relatives and your partner. For cohabiting couples, this isn’t about formality – it’s about protection, fairness, and compassion.

What About Property Ownership?

If you own property together, how it’s registered matters a lot. You can own your home as either:

1. Beneficial joint tenants – Both partners own the property equally. When one dies, the other automatically inherits their share.
2. Tenants in common – Each partner owns a defined share (for example, 60/40). That share doesn’t automatically pass to the surviving partner; it follows the terms of your Will or intestacy rules.

If you’re tenants in common and your partner dies without a Will, their share could go to someone else – even if you’ve paid the mortgage together. That’s why it’s important for unmarried couples to write a Will clearly stating how property should be handled.

Can an Unmarried Partner Claim Anything?

In some cases, yes – but it’s far from guaranteed.

A surviving partner can make a claim under the Inheritance (Provision for Family and Dependants) Act 1975, asking for financial provision from the deceased’s estate.

But this process is lengthy, emotionally draining, and often expensive. It usually involves going to court, and outcomes depend on factors like financial dependence or contributions to shared assets. Having a Will in place avoids this entirely. It ensures your partner’s rights are respected without court intervention.

What About Inheritance Tax?

Here’s another key difference between married couples and unmarried partners.

If you’re legally married or in a civil partnership, your estate can be passed to your surviving spouse or civil partner completely free of inheritance tax. You can also transfer any unused tax-free allowance between you.

But if you’re cohabiting partners, the surviving partner may have to pay inheritance tax on what they inherit – even if it’s the home they shared. This can create serious financial strain and, in some cases, force a property sale just to cover the tax bill.

That’s another reason a carefully written Will and financial planning are vital for unmarried couples. With the right advice, you can plan ahead and reduce the amount of tax your loved ones pay.

Why It’s So Important for Unmarried Couples

If you’re not married or in a civil partnership, writing a Will is about securing your shared life and legacy. It’s not about being morbid or controlling – it’s about showing care and foresight.

Having a Will gives you and your partner:

• Peace of mind knowing your wishes will be followed
• Legal protection for your assets and your partner
• Security for children or dependents
• A safeguard against potential family disputes

In short, it ensures that the person you’ve built your life with is treated fairly, even if the law doesn’t automatically see it that way.
