Overview

Clear, thoughtful legal advice before fertility treatment begins

Understanding fertility law before treatment starts

Fertility treatment is emotionally demanding, and the legal framework behind it is complex. Decisions made before treatment begins can affect parental status, responsibility and a child’s legal position so taking advice early gives you clarity and helps you avoid unintended consequences later.

Whether you are starting treatment as a couple, pursuing parenthood on your own, using a donor or considering donation yourself, the law treats each situation differently. We help you understand how the rules apply to you, in plain language, so you can move forward with confidence.

Will I be the legal parent?

If you are not married or in a civil partnership, and you are not giving birth, specific parenthood forms usually need to be completed before treatment begins. If they are not, you may not have legal parental status, regardless of your role in the child’s life. These arrangements have long-term implications. Parental responsibility does not disappear if relationships change, and misunderstandings at the outset can be difficult to resolve later. We help you put the correct legal foundations in place from the start.

Known donation and co-parenting arrangements

Some people enter fertility treatment with a friend or known donor. These arrangements can work well, but they often raise complex questions about roles, expectations and future decision-making. A carefully considered co-parenting or pre-conception agreement allows everyone involved to discuss key issues before a child is born. While these agreements are not legally binding in every respect, they can reduce uncertainty and provide a clear framework if circumstances change.

Frequently asked questions

Fertility law FAQs

Before any treatment can take place, you must give your consent to ensure your eggs, sperm and embryos are used in the way you want. As part of this process, you may need to confirm:

  • How long your eggs, sperm or embryos will be stored for

  • What should happen to your eggs, sperm or embryos if you die

  • What should happen to any embryos if you and your partner separate

You are able to specify your wishes clearly in your consent forms and, in certain circumstances, update or withdraw your consent in line with the applicable regulations.

Under English and Welsh law, a child can only have two legal parents, known as legal parenthood. The individual who gave birth to the child will automatically be the legal parent, regardless of whether they are the biological parent of the child or not. If the individual who gave birth to the child is married or in a civil partnership then their partner will become the other legal parent; unless they do not consent to the treatment that gave rise to the conception.

It is important to be aware that parental responsibility is a separate issue from legal parenthood. When undertaking treatment, it is important to consider parental responsibility and how to obtain it. Parental responsibility covers the legal rights, responsibilities and authority a person has for a child, such as making decisions about their care and upbringing.

A co-parenting agreement covers:

  • Who the child will live with
  • Who will have parental responsibility
  • Who will be named on the birth certificate
  • How much contact the child will have with the other parent 
  • Decision making once the child is born e.g. where they will go to school
  • Consent to treatment and storage and what happens if there is a dispute?

Whilst undergoing fertility treatment, you will not be entitled to statutory time off.  However, the Advisory, Conciliation and Arbitration Service (ACAS) guidance states that employers should treat appointments related to IVF in the same way as any other medical appointment, under the terms and conditions of the contract of employment. If the implantation is successful, you will be entitled to maternity leave. You should consult your employment contract to find out on what terms. 

A document which sets out how the arrangement will work between your known donor, or co-parent, before you conceive. Please note, a preconception agreement cannot be used in cases of surrogacy, where different rules apply. Preconception agreements are not legally binding, however they are still worthwhile as they can help you plan out some of the more difficult details of the arrangement such as:

  • Who will the child live with and spend time with
  • Who will have financial responsibility
  • Where will the conception take place, at home or at a clinic
  • Set out any issues such as responsibility for schooling or medical decisions
  • Who will be the legal parents of the child after fertility treatment?
