A couple reviewing legal documents together at their home office desk, planning their financial protection and will

Moving in with your partner is a huge and exciting milestone. Both of you are picking out furniture, choosing decorations, splitting bills and building a future together. But, if you are not legally married or in a civil partnership, there is a big hidden trap that many people fall into: the law treats you as legal strangers.

There is a widespread belief in the UK that if you live together for long enough, you can become ‘common law spouses’, meaning you gain the same legal protections as legally married spouses. Unfortunately, this is a myth, and common law spouses do not exist under English law.

If one partner passes away without leaving a Will, the consequences for the surviving partner can be both financially and emotionally devastating. Here is why a Will is an ultimate safety net for your relationship:

1. The Intestacy Trap

When a person dies without leaving a Will, their assets will be split according to what is known as the intestacy rules. Under these rules, the hierarchy of who inherits depends entirely on who is surviving in your family. It prioritises spouses, civil partners, children, parents and siblings. Unmarried partners unfortunately do not make the list.

No matter if you are together for 5 years or 50 years, if you are not married or in a civil partnership and your partner dies without a Will in place, you will not have an automatic right to inherit anything from their estate.

2. Could You Lose Your Home?

What will happen to your home depends on how you own it. Without a Will, the risks are much higher:

Tenants in Common

If you own the property as tenants in common (where you each own a specific percentage share of property), your partners share does not automatically pass to you on their death unless your partner specifically makes provision for this in a Will. Without a Will, their share will pass to their family under the intestacy rules. You could therefore find yourself owning a house with your late partner’s parents or siblings who will have a legal right to force sale to get their money out.

Sole Name

If your house or tenancy is in your partner’s name only, you will have no automatic right to their share. You could therefore be legally forced to move out of your own home during a period of grief.

3. Claiming What’s Yours

Unmarried partners may sometimes sue the estate under the Inheritance (Provision for Family and Dependants) Act 1975, and you would need to prove you have lived together for a period of time and were financially dependent on them. However, you should think about what that means: you would be taking your partner’s grieving family to court and be spending thousands of pounds in legal fees to secure a roof over your head.

The Answer: Getting a Will

Leaving the future of your partner up to intestacy laws is a risk not worth taking. When you write a Will, it is not about tempting fate, it is about securing your loved ones and ensuring that the person you chose to spend your life with is protected should the worst-case scenario happen.

Putting a Will in place is quick, straightforward and will cost only a fraction of a legal dispute. Here at Franklins, whether you’re in Northampton, Milton Keynes, or surrounding areas, we can help get your wishes put in writing and protect your loved ones.

Frequently Asked Questions

No. Unlike married spouses, unmarried partners have no automatic inheritance rights under English law, regardless of how long you’ve lived together. If your partner dies without a Will, you will not inherit anything unless they have specifically named you in a Will. This is why making a Will is essential for unmarried couples.

No. This is a common misconception. There is no legal status called “common law marriage” in England, Scotland, Wales, or Northern Ireland. Living together, even for decades, does not give you any automatic legal rights or protections. Only a legal marriage or civil partnership provides these protections.

Their estate will be distributed according to the intestacy rules, which follow a strict order of priority: spouses, civil partners, children, parents, siblings, and more distant relatives. As an unmarried partner, you will not inherit anything unless you can prove financial dependency and bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975, which is costly and uncertain.

You may be able to claim under the Inheritance (Provision for Family and Dependants) Act 1975, but only if you can prove you lived together for at least two years and were financially dependent on them. You would need to take a legal claim against the estate, which is expensive, emotionally draining, and not guaranteed to succeed. A Will avoids this entirely.

Making a Will is the most important step. Each partner should clearly state who inherits their assets, including property. Beyond a Will, you may also consider: reviewing how you own property (joint tenants vs tenants in common), creating a cohabitation agreement, and discussing powers of attorney in case one partner becomes unable to make decisions.

Without a Will, their share will pass to their family under the intestacy rules. You could find yourself co-owning the property with their parents or siblings, who may have the legal right to force a sale. With a Will, your partner can leave their share directly to you, keeping the property in your control.

Making a Will is quick and affordable, often costing far less than a legal dispute over an estate. The cost varies depending on complexity, but a basic Will is usually very reasonable. It’s a small investment to protect your relationship and give you peace of mind.
