Previous Children and Fertility Funding

Of all the eligibility rules, this is the one that most often comes as a surprise. In most areas that fund fertility treatment publicly, a living child already in the picture ends the funding, and the child does not have to be yours. A child your partner had in an earlier relationship, whom you may see at weekends or may never have met, can affect your funding.

It helps to understand the reasoning. An age limit is about whether treatment is likely to work. This one is about how a limited budget gets shared out, so it is a funding rule rather than a judgement on your family.

What I can do is set out how the rule is normally written, where the room for discussion sits, and the good options that remain if public funding is not available.

What the rule usually says

The common wording refers to neither partner having a living child, from the current relationship or any previous one. Read carefully, most policies turn on three things.

• A living child. A child who has died does not usually count against you, and policies generally say so explicitly.
• Either partner. The child does not need to be yours biologically or legally for it to affect your application, if they are your partner's.
• Residence or contact is often irrelevant. This is the part that surprises people most. A biological child living full-time with another parent, several hundred miles away, commonly still counts. Some policies do qualify this, and a few consider whether the child lives with you, so it is worth checking the exact phrasing rather than assuming the strictest reading.

Some policies also address related situations directly. Whether the rule applies to a child conceived by donor. Whether a surrogacy arrangement counts. Whether a child the couple placed for adoption counts. There is no consistent national answer to any of those, which is exactly why the phrasing matters.

It varies by area, and the variation is real

Public funding for fertility treatment is commissioned locally, so this criterion is written locally too. The category appears almost everywhere. The details do not match.

I have seen the rule stated as no living children at all, as no living children in the current relationship, and as no living children living in the household. Those three versions produce opposite answers for the same family. I have also seen policies that treat a partner's child differently from your own, and policies that make an exception where the previous child was conceived with fertility treatment that the couple paid for themselves.

So do not take a version you have read anywhere, including here, as your version. Get your own commissioner's published fertility policy and read the clause. If the wording is ambiguous, ask in writing for the interpretation they apply, because an ambiguity resolved verbally at a desk is not something you can rely on later. NHS criteria covers how to find that document and what else is in it.

Adoption and stepchildren

These are the two situations where the answer is least predictable and most worth chasing.

An adopted child is usually treated as a child of the household, because the rule is generally framed around parenting rather than genetics. That can affect couples who adopted because they could not conceive, and then sought treatment afterwards. Some policies make an exception, most do not.

A stepchild is the genuinely grey one. If your partner's child lives with you, many policies count them. If that child lives elsewhere and you have no parental role, some policies still count them, on the basis that your partner is already a parent. Others do not. This is the clause most likely to have been revised recently, so check the current version rather than the one someone quoted you two years ago.

Fostering is different again, since a fostered child is not legally yours, and policies rarely mention it. Ask rather than assume.

Secondary infertility

If the child is yours and you are trying for another, you are dealing with secondary infertility, and it is worth understanding how it is handled. Clinically it is investigated much the same way as primary infertility. A previous pregnancy is reassuring about some things and tells you nothing about others, because tubes can become blocked, sperm quality can fall, endometriosis can progress and ovarian reserve declines with every year that passes.

For funding, though, having a child is usually the disqualifier, so secondary infertility is the situation most likely to be investigated on the public system and treated on your own money. It helps to know that from the start, so you can plan the cost of treatment alongside the free tests.

Emotionally it deserves more recognition than it gets. Wanting to give your child a sibling is a real and important wish, and it is fine to seek support for it.

When the answer is no

There are still good options. Check whether the policy has an exceptional or individual funding route, and if it does, understand that a request built around a specific clinical circumstance does better than one built around fairness. Ask whether the criterion is applied at referral, at assessment, or both, and whether anything about your situation is genuinely ambiguous under their wording, because ambiguity is where an argument exists at all.

If it is clearly a no, move the conversation to planning private treatment. Ask an NHS unit whether it treats self-funding patients, since that is sometimes cheaper than a standalone private clinic. Get the all-in cost of getting to one live birth attempt including a frozen transfer, in writing, from more than one place. Where age is a factor, ask what delay costs you in odds, because that is the number the decision actually turns on. IVF covers what a cycle involves and what it typically costs.

None of this is legal, financial or medical advice, and I am not the person who decides your case. The clause in your own policy is. Read it, ask what it means, and get the answer in writing.
