Splitting up is complicated enough without the added frustration of a joint insurance policy standing in the way of moving on. Whether it’s a joint home insurance policy, a car insurance policy, or a life insurance policy, what happens when your ex simply won’t play ball? Here’s what you need to know under UK law and practice.

Why Joint Policies Become a Problem After a Split

When you take out a joint policy with a partner, both of you are named policyholders. That means both parties have equal rights over the policy including the right to block or refuse changes. Insurers generally require the consent of all named policyholders before making significant amendments, such as:

• Removing one person’s name from the policy
• Changing beneficiaries (particularly relevant for life insurance)
• Altering coverage levels or adding exclusions
• Transferring the policy entirely into one person’s name

If your ex refuses to give that consent, you can quickly find yourself stuck legally tied to someone you no longer share a life with.

Can You Make Changes Without Their Agreement?

In most cases, no. Under UK contract law, a joint insurance policy is a contract between the insurer and both policyholders. Neither party can unilaterally alter the terms without the other’s agreement. Attempting to do so without consent could even invalidate the policy or give the insurer grounds to decline a future claim.

However, there are some exceptions and workarounds worth exploring.

What You Can Do If Your Ex Refuses

1. Contact the Insurer Directly

Start by speaking with your insurer. Explain the situation clearly. While insurers cannot force your ex to agree, many have procedures for dealing with relationship breakdowns. They may:

• Offer to split the policy into two separate single policies
• Advise you on the specific consent requirements for changes
• Flag that non-cooperation could affect both policyholders’ cover

Some insurers are more accommodating than others, so it’s always worth asking what options are available.

2. Take Legal Advice

If significant assets are involved such as a joint home insurance policy tied to a property you own together — you should seek legal advice. A solicitor can advise whether the terms of any divorce or separation agreement can compel your ex to cooperate. In some cases, a court order obtained as part of financial remedy proceedings can require your ex to consent to changes.

3. Apply for a Court Order

As part of divorce or dissolution proceedings, the family court in England, Wales, Scotland, or Northern Ireland has broad powers to make financial orders. If the joint policy relates to a matrimonial asset (such as the family home), a court can order your ex to remove themselves from — or transfer — the policy as part of the financial settlement.

This route takes time and money, but it is a legitimate legal remedy if your ex is being obstructive.

4. Cancel the Policy Entirely

If you are a named policyholder, you may have the right to cancel the policy altogether, even without your ex’s agreement though this depends on the insurer’s terms and conditions. Be cautious: cancelling a home insurance policy mid-term could leave you without cover and may also breach mortgage conditions if the property is mortgaged. Always check before cancelling.

If you do cancel, make sure you immediately arrange alternative cover in your own name.

5. Remove Yourself From the Policy

Rather than trying to remove your ex, it may be simpler to remove yourself and take out a new policy. This is often more straightforward because you are not trying to alter the other person’s rights — you are simply relinquishing your own. Again, check with the insurer, as some policies require both parties to agree to any change in named policyholders.

Life Insurance: A Special Case

Joint life insurance policies are particularly thorny after a separation. Most joint life policies pay out on a “first death” basis, meaning the surviving partner receives the payout — even if that person is now your ex-spouse or former partner.

Key points to be aware of:

• You cannot change the beneficiary of a joint life policy without both parties’ consent. If your ex refuses, the policy terms remain as they are.
• Separation does not automatically end a joint life policy. Even divorce does not alter the policy terms unless you take active steps.
• Some insurers allow a policy to be split into two single policies on separation — known as a “separation option” — but this must usually be requested within a set timeframe and both parties may need to agree.

If you are concerned that your ex could benefit financially from your death (or vice versa), speak to a protection adviser and your insurer as soon as possible.

Home Insurance: Protecting the Property

If you remain living in the jointly insured property after separation, it is essential that the home remains insured. If your ex is uncooperative:

• Contact the insurer to ensure cover remains in place while the dispute is resolved
• If you are in the process of buying out your ex’s share, inform the insurer of the change in circumstances
• If your ex cancels the policy without your knowledge, the insurer should notify all named policyholders — check your policy terms

Bear in mind that a gap in home insurance can breach the terms of your mortgage, which could have serious financial consequences.

Practical Steps to Take Right Now

If you are in this situation, take these steps as soon as possible:

1. Review your policy documents to understand the exact terms around consent and changes.
2. Contact your insurer to explain the situation and ask what options are available to you.
3. Document all attempts to contact your ex regarding the policy this may be useful if you need to go to court later.
4. Seek legal advice if the policy is linked to a property or significant financial asset.
5. Consider mediation a mediator can sometimes help former couples resolve practical disputes like this without the cost and stress of going to court.

The Wider Lesson: Untangle Joint Finances as Soon as Possible

Dealing with joint policies after a separation is a reminder of just how financially intertwined couples become. The sooner you can identify all joint financial products and work towards separating them, the better. Alongside insurance policies, don’t forget to review joint bank accounts, mortgages, pension nominations, and any lasting powers of attorney.

If your ex is refusing to cooperate with any of these, a solicitor specialising in family law can advise you on your rights and the most effective way to move forward.
