Why fertility treatments and surrogacy need early legal advice

December 16, 2025

In today’s society, family structures are increasingly diverse and there are a variety of routes to parenthood. This presents complex legal questions regarding legal parenthood, parental rights and responsibilities, and the welfare and rights of the child. Early legal advice is essential to safeguard the intended legal relationships, prevent future disputes, and ensure that all parties and the child are properly protected throughout the process leading to the birth of the child, and beyond.

Fertility Law and Surrogacy Law are complex. There are different legal processes depending on factors such as whether you are married or in a civil partnership, a same-sex couple, a single parent, using a donor or a surrogate. This complexity can easily lead to misunderstandings and errors, which can have significant and long-term implications for parties and the child. It is essential to seek specialist legal advice before commencing any process.

Early advice and planning can also deal with important child arrangements matters such as:

  • Where and with whom the child will live.
  • With whom the child will have contact and how.
  • Aspects of the child’s upbringing such as schooling and faith.
  • Financial support for the child.

This can minimise uncertainty and the risk of future disputes. It is important to understand the long-term impact of the creation of legal relationships, which can remain even in the circumstances of a family breakdown. 

It is also advisable to think early in the process about Wills and Estate Planning. A Will can cover important matters such as:

  • Guardianship for the child in the event of your death.
  • Provision for the child, such as whether that’s through a trust and, if so, what type of trust.
  • Who the trustees of the trust should be.
  • If you have any embryos / eggs / sperm stored, what happens to them on your death.
  • If you have donated your eggs or sperm, whether you want any children born from those donations to have access over and above their legal entitlement to information about you and, if so, how that information will be provided.

Due to the complexities of creating legal parent-child relationships, the corollary is that there can be complications with matters which arise upon the death or incapacity of a party.

For example, in a surrogacy arrangement the child is treated as the surrogate’s child under the Law until a Parental Order or Adoption Order is made by the Court transferring legal parenthood to the intended parent. From the surrogate’s position this means that the child (or their guardian, if the surrogate dies before the Parental Order but while the child is under 18) would benefit under the intestacy rules and/or would have standing to bring a claim against the surrogate’s estate (or that of their married or civil partner) for reasonable financial provision under the Inheritance (Provision for Family and Dependants) Act 1975.
