Key points
- The legal owner is whoever is named at HM Land Registry. The beneficial owner is whoever is entitled to the value. They are not always the same people.
- If you are not on the deeds, you can still have a beneficial interest through a written declaration, a constructive trust, a resulting trust or proprietary estoppel.
- Unmarried partners do not get the automatic rights to the home that spouses have, so proving a beneficial interest is often the only route to a share.
- If you have a beneficial interest, you can protect it at HM Land Registry with a restriction.
Owning a house has two layers. The first is legal ownership: the names on the title at HM Land Registry, who can sign to sell or mortgage it. The second is beneficial ownership: who is actually entitled to the value, and in what shares. Most of the time they match. When a couple separate, the gap between them is where the arguments happen.
If you live in a home you are not named on, or you own one jointly but paid unequal amounts, this guide explains where you stand. For a quick indication, try our TOLATA checker.

Legal owner and beneficial owner
| Legal owner | Beneficial owner | |
|---|---|---|
| Who | The people named on the title register | The people entitled to the value of the property |
| Can sell or mortgage it? | Yes, they sign the documents | Not directly, but their interest can be protected |
| Shown at HM Land Registry? | Yes | Not the shares themselves. A restriction may show that a beneficial interest exists |
| On a sale | Receives the money in the first place | Is entitled to their share of it |
Wherever two or more people own property, or someone owns it for another person, the law treats it as held on a trust of land. The rules for disputes are in the Trusts of Land and Appointment of Trustees Act 1996, which is why these claims are called TOLATA claims.
If the home is in joint names
If you are both on the title, you are both legal owners. The starting point for the beneficial shares is equal, whatever each of you paid, unless you signed a declaration of trust saying otherwise. A declaration is normally conclusive.
Without one, a partner arguing for unequal shares has to prove you intended that, as in Stack v Dowden and Jones v Kernott. It is possible, but the courts expect strong evidence.
If the home is in one name
If the home is in your partner’s sole name, the starting point is that they own all of it. You have to prove that you have a beneficial interest, and then how big it is. This is the situation behind most disputes, and our guide to what happens when your partner’s name is on the deeds walks through it.
One difference from married couples matters a great deal here. A spouse has statutory “home rights” to live in the family home even if it is in the other spouse’s name, and can register them. Unmarried partners have no equivalent. If you are not on the title, your security depends on proving a beneficial interest, or on a court order such as an occupation order in limited cases.
Four ways a beneficial interest can arise
| Route | How it arises | What you need to show |
|---|---|---|
| Express declaration of trust | Your partner signs a written declaration that you own a share | A document signed by them, as the law requires for declarations about land |
| Common intention constructive trust | You both intended you would share the home and you acted on that | Discussions about ownership, or conduct such as paying towards the purchase or mortgage, plus reliance. See our constructive trusts guide |
| Resulting trust | You paid part of the purchase price | A direct contribution when it was bought. In family homes, courts now usually look at the whole picture through a constructive trust instead |
| Proprietary estoppel | Your partner assured you of a share and you relied on it to your cost | Assurance, reliance, detriment and unfairness. See our proprietary estoppel guide |
What counts as a contribution
Courts look at the whole course of dealing between you, but some contributions carry more weight than others.
| Contribution | How much it usually helps | Why |
|---|---|---|
| Paying part of the deposit or purchase price | Strong | A direct contribution to buying the property |
| Paying the mortgage | Strong | Pays for the property over time |
| Paying for major improvements or an extension | Moderate to strong | Adds value, especially if done because you believed you had a share |
| Paying household bills so your partner could pay the mortgage | Moderate | Can support an inferred intention if it was part of a shared plan |
| Looking after the home and children | Weak on its own | Valued highly in divorce, but in property law it rarely creates an interest by itself |
| Doing DIY and decorating | Weak | Usually seen as ordinary family life unless substantial |
How to prove it
- Bank records showing payments towards the deposit, mortgage or major work
- Messages and emails about owning the home together or being put on the deeds
- The purchase file, which may show who paid what and any discussion with the conveyancer
- Mortgage applications, which sometimes record both incomes being relied on
- People who heard your partner talk about the home being yours too
Protecting your interest: a restriction at HM Land Registry
If you have a beneficial interest in a home in your partner’s sole name, you can apply to HM Land Registry for a restriction on the title, using form RX1. A restriction means the property cannot be sold or mortgaged without the conditions in it being met, which prevents your partner quietly selling and keeping the money.
You cannot protect this kind of interest with a notice, because the law does not allow notices for interests under a trust. A restriction is the right tool. Applying for one without reasonable cause can expose you to a claim, so take advice first.
Living in the property also matters. Someone in actual occupation with a beneficial interest can, in some circumstances, have rights that bind a buyer or lender. Lenders know this, which is why they ask adult occupiers to sign consent forms.
What happens when you separate
If you cannot agree, either of you can apply to court under section 14 of TOLATA to decide who owns what and whether the home should be sold. Before that, there should be correspondence setting out each side’s case, and usually mediation. Our TOLATA claim guide explains each stage. Many cases settle once the evidence is set out.
An example
Kerry moved into Mark’s flat in Romford in 2016. In 2019 they sold it and bought a house in Upminster in Mark’s sole name, because Kerry was self-employed and the lender preferred one applicant. Kerry put £20,000 of her savings into the deposit, and they agreed in texts that the house was “both of ours”. They have now separated.
Kerry has good evidence of a common intention to share, through the texts and her deposit, and she relied on it. She has a strong argument for a beneficial interest. The size of her share would depend on the whole course of dealing, not just the £20,000.
This is an illustrative example, not a real case.
Frequently asked questions
Can I have a beneficial interest if I am not on the mortgage?
Yes. The mortgage is a contract with the lender, and the title shows legal ownership. Neither decides beneficial ownership, which depends on the evidence of what you both intended and contributed.
Does paying rent to my partner give me a share?
Usually not. Paying rent normally suggests you were a tenant or lodger rather than a co-owner. If the payments were described as going towards the mortgage as part of a plan to share, the position may be different.
Is a beneficial interest the same as a right to live there?
No. A beneficial interest is a share in the value. Whether you can stay living there is a separate question, which the court can decide in a TOLATA claim alongside the shares.
What if my partner sells the house without telling me?
If you registered a restriction, the sale should not complete without the conditions being met. If not, you may still have a claim against your partner for your share of the proceeds, and in some cases against the buyer. Act quickly.
Do married couples need to prove a beneficial interest?
Not usually on divorce. The court divides property under the Matrimonial Causes Act 1973 according to needs and fairness, whoever owns it. Beneficial interest matters mainly for unmarried couples.
