Can I Charge My Ex's New Boyfriend Rent?

Joint ownership complicates matters

If you jointly own the property with your ex, you both have a stake in it. The exact split of equity may not have been formally agreed, but in practical terms she has as much right to live there as you do.

That shared ownership creates a problem if you want to charge her new partner rent. He would not be your tenant. He would be living there as her guest or partner, in a home she part owns.

Whether she can invite someone to live there without your consent may depend on the terms of your ownership arrangement and any court orders relating to your separation. Without a written agreement between you covering who can occupy the property and on what terms, demanding rent from someone she has invited to live with her becomes difficult to enforce.

Could his presence affect mortgage payments?

If you and your ex are both contributing to the mortgage, her boyfriend moving in does change the household finances in one sense. Another adult will be living there, potentially sharing costs with her.

You might reasonably argue that if he is contributing towards the mortgage or household bills, your own share of the payments should be reconsidered. However, you cannot unilaterally reduce your mortgage contributions simply because someone else is helping with expenses. Any adjustment would need to be agreed between you, ideally formalised through a solicitor.

There is no automatic legal mechanism that forces her to renegotiate simply because her circumstances have changed. That said, a change in living arrangements could become relevant if there are ongoing financial matters from your separation, particularly where court orders are involved.

Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.

What are your realistic options?

The most practical approach is to have a direct conversation with your ex and try to reach an agreement you can both accept. This might cover:

• Whether her partner will contribute to mortgage payments or bills
• How any additional contributions affect what you pay
• Longer term plans for the property, including whether to sell

How well this works depends on your relationship with your ex and how willing she is to discuss arrangements openly. If direct communication is difficult, putting proposals in writing may help keep things clear and reduce misunderstandings.

If you cannot reach agreement, you may be able to apply to the court for a Property Adjustment Order, which could determine how the property is dealt with going forward.

Get legal advice first

Before raising this with your ex or making any demands, speak to a solicitor who handles family property matters. They can explain your actual rights and help you avoid steps that could backfire. Bring any joint ownership documents, mortgage statements and court orders from your separation.

If cost is a concern, you may be able to get initial guidance through a free legal clinic or Citizens Advice. Some family mediators can also help you and your ex reach agreements about property without going to court.

In summary, charging rent directly to your ex's new partner is generally not feasible when the property is jointly owned. But there may be other ways to adjust the financial arrangements if his presence changes the household setup.
