Should Separated Parents Insure Each Other?

You can take out life insurance connected to an ex-partner who pays child maintenance, but not behind their back. UK insurers will not let you secretly insure someone: the person whose life is covered has to apply, answer the medical questions and give their consent. So the real question is not only "can I take out life insurance on my ex who pays child maintenance", but how to arrange it so that it actually protects the children — and whether a cleaner structure than insuring your ex directly would do the job better.

The good news is that the legal obstacle people worry about, insurable interest, is usually satisfied here. If you rely on maintenance from your ex, you stand to lose money if they die, and that loss is exactly the kind of financial interest a policy is allowed to protect. The practical obstacles — consent, ownership, who pays the premiums, and what happens if the arrangement is quietly dropped — are the ones that actually decide whether the money reaches your children when it is needed.

This page explains insurable interest between separated parents in plain terms, sets out the two ways to structure the cover, and shows how to write it so the children benefit whichever parent dies, not just the one who happens to be paying maintenance today.

The short answer: yes, but only with their agreement

There is no rule against separated parents insuring each other. It happens all the time, usually agreed as part of sorting out the finances after a separation. What you cannot do is arrange cover on your ex-partner without their involvement. A life-of-another application requires the person being insured to sign it, disclose their medical history and consent to the cover, because the insurer is assessing their health and their risk, not yours. Whether the insurer offers cover, and on what terms, then depends on underwriting — their age, health and lifestyle all feed into it.

That makes this a co-operative arrangement or nothing. For many separated couples that is workable: both parents want the children provided for, and agreeing mutual cover is one of the less contentious things to settle. For others, where communication has broken down, it is simply not going to happen, and the answer is to insure the life you do control — your own — for the children's benefit instead. Neither route is second best; they solve slightly different problems, and plenty of families use both.

Before you decide which, it helps to be clear about what you are actually protecting against: the loss of the income the children depend on. That income can disappear because the paying parent dies, and it can also disappear because the resident parent dies and the household that received it is gone. Both are real, and a plan that only covers one of them leaves a gap. The single-income exposure a resident parent carries is set out in what one income and two children looks like with nobody behind you.

Insurable interest: why maintenance gives you one

Insurable interest is the principle that you can only insure a life if you would suffer a real loss from that person's death. It stops life insurance being used as a wager on a stranger. You have an unlimited insurable interest in your own life, and spouses and civil partners are treated as having one in each other. Beyond that, you generally need to point to a financial relationship — a debt owed to you, or payments you depend on.

Child maintenance is one of those payments. If your ex-partner pays maintenance and that money stops when they die, you and the children are financially worse off, and that expected loss is what gives you an insurable interest in their life. In principle the interest is measured by the value of what you stand to lose, so cover in the region of the maintenance still due until the children finish their education is straightforward to justify. The legal roots of this go back a long way, but the modern practical position is simply that insurers will write the cover where a genuine financial dependency exists and the life assured consents.

It is worth knowing that maintenance assessed through the Child Maintenance Service is not a debt of the estate and stops when the paying parent dies — the future payments do not carry on out of what they leave. That is precisely why cover matters: nothing else automatically replaces the lost income. You can check how the service treats a paying parent's circumstances through gov.uk on the Child Maintenance Service.

Two ways to structure it

There are two clean structures, and the difference between them is who owns the policy and whose life it covers.

The first is a life-of-another policy: you own a policy on your ex-partner's life, they consent and are medically assessed, and you are the one who receives the payout if they die. This puts control in the hands of the person who depends on the money, which is its main advantage. You know the premiums are being paid because you are paying them, and the policy cannot be cancelled without your knowledge.

The second is for each parent to take out their own policy, written in trust for the children. Here each of you insures your own life — no insurable-interest question arises, because everyone has an unlimited interest in their own life — and each policy is placed in trust with the children as beneficiaries and trustees you both agree on. Whichever parent dies, a policy pays out for the children, and because it is in trust it reaches the trustees quickly, outside the estate, without waiting for probate. For separated parents who can agree the principle but not much else, this is often the more robust arrangement, because neither of you is dependent on the other keeping a policy going. It also naturally covers both lives, which the single life-of-another policy does not.

Who should own and pay for the policy

Ownership decides two things that matter enormously after a death: who gets the money, and who can stop the cover. If you rely on the maintenance, you want both answers to favour you.

If your ex owns a policy on their own life and simply names the children or you as beneficiaries, they can stop paying it, change the beneficiary or cancel it entirely without telling you, and you may only discover the cover has gone when it is too late to matter. If instead you own the policy — either a life-of-another policy on them, or your own-life policy in trust — you control the premiums and the arrangement is not at the mercy of the other parent's goodwill or their finances. Where a life-of-another policy is used, paying the premiums yourself is usually the safest choice for the parent who depends on the payout.

Trusts do a related job. A policy written in trust for the children means the payout is not tied up in the estate, does not pass under the deceased parent's will, and reaches the trustees promptly to be used for the children. It also keeps the money out of the hands of a new partner or other beneficiaries of the estate. Choosing trustees both parents accept, and who will actually act, is part of making the arrangement stick. If you have named a guardian to step in, remember that naming one and funding one are separate tasks, which we cover in why naming a guardian is free but funding one is not, and the question of who a child actually goes to is dealt with in who actually takes your child when a single parent dies.

Matching the cover to the maintenance

Maintenance is a monthly income, not a lump sum, so the cover that fits it best is one that also pays a monthly income: family income benefit. Rather than paying a single large amount that then has to be invested and made to last, family income benefit pays a regular sum for the remainder of the policy term from the date of the claim, which mirrors how maintenance would have arrived.

Two settings make it fit the job. Set the term to run until the youngest child finishes full-time education, since that is roughly how long maintenance would have continued. And set the monthly amount at, or near, the payments that would still have been due, so the children are kept in much the same position they would have been in had the paying parent lived. Because the payments reduce the total the longer the policy has run, this shape of cover is designed around a need that also shrinks over time, which is why it suits maintenance rather than, say, a mortgage that has to be cleared in full.

Whether an insurer offers the cover, and at what terms, still comes down to underwriting the life assured, and a health condition can lead to an exclusion or a loading rather than a flat refusal. If cover is offered with a condition attached, it is worth weighing rather than dismissing, a decision we look at in whether to take cover that comes with an exclusion. You can see what is available for your own circumstances by getting life insurance quotes through an FCA-authorised broker, who can also advise on the trust wording.

Insure both parents, not just the payer

It is natural to focus on the parent who pays maintenance, because their death is the one that visibly stops an income. But the resident parent's death is at least as serious for the children, and often more disruptive. If the parent the children live with dies, the children usually move to the other parent's household, with all the upheaval that brings — a new home, sometimes a new school, and a receiving household whose costs suddenly rise.

Cover on the resident parent's life, written in trust, gives whoever takes the children on the means to absorb that change rather than being financially overwhelmed by it. This is the strongest argument for the each-parent-insures-themselves structure: it treats both parents as load-bearing, because to the children they both are. The related planning for a carer or the person who would step in is covered in what happens when a special guardianship order ends with the guardian's death and, for couples where one cares for the other, in what happens if the carer dies first.

Putting it in the settlement and keeping it alive

Separated parents often agree cover as part of their financial arrangements, and it is sensible to write down what has been agreed: whose life is covered, who owns each policy, who pays the premiums, the amount, the term and the trust arrangements. A court cannot compel someone to pass a medical, but parties frequently agree to put and keep cover in place as a term of their settlement, and recording it removes later argument about what was promised.

Keeping the cover alive is the part that quietly fails. Premiums lapse when a payer forgets, moves bank, or hits a rough patch, and a lapsed policy protects no one. Building in a way to check the cover is still in force — an annual confirmation, or simply owning the policy you rely on so you control the payments — is what turns a good intention into a working plan.

Frequently asked questions

Can I take out life insurance on my ex-partner?

Not without them. UK insurers require the person whose life is covered to apply, answer the medical questions and consent, so it has to be a co-operative arrangement. You also need an insurable interest, which lost maintenance payments can provide. Many separated parents agree it within their financial settlement.

Who should own and pay for the policy?

If you rely on the maintenance, owning the policy yourself means the money comes to you directly and you can see the premiums are being paid. If your ex owns it, they can stop it without telling you. Alternatively, both of you write your own policies in trust for the children, so neither depends on the other keeping cover going.

What kind of cover matches maintenance?

Family income benefit, because it pays a monthly amount for the rest of the term rather than a lump sum, which is what maintenance actually is. Set the term to end when the youngest finishes education, and set the amount at the payments that would still have been due.
