The United Kingdom has one of the most developed legal frameworks for assisted reproduction in the world. The Human Fertilisation and Embryology Act 1990, substantially amended in 2008, governs fertility treatment, donor conception, and the legal parenthood of children born through these methods. The Human Fertilisation and Embryology Authority (HFEA) regulates licensed clinics.
In the UK, sperm donation through a licensed clinic is legal and well-regulated. Anonymous donation was ended in 2005: all donors must consent to the release of identifying information to donor-conceived people who request it upon reaching age 18. Donors are limited to creating families in ten families. The HFEA maintains a central register of all donor-conceived people and their donors.
Legal parenthood in the UK following donor conception depends on the circumstances. For heterosexual couples, if the mother's husband or civil partner consents to treatment, they are the legal second parent. For same-sex female couples, if both partners consent to treatment at a licensed clinic, both are legal parents from birth — no adoption is required. For single women, they are the sole legal parent.
The second parent consent process is critical. Both partners must sign specific consent forms (WP and PP forms) at the licensed clinic before treatment begins. If these forms are not completed correctly, the non-biological partner will not automatically be a legal parent and will need to apply to adopt the child — a longer and more complex process.
Known donor arrangements are legally complex in the UK. If a known donor donates through a licensed clinic, he has no legal parental status and cannot be held liable for child support. If he donates outside a clinic (home insemination), the legal position depends on the mother's relationship status: if she is single, the donor may be the legal father; if she has a same-sex spouse who has given clinic consent, the donor is not the father.
Co-parenting agreements between friends are not legally binding in the UK in relation to parental responsibility. Courts dealing with disputes about children will apply the Children Act 1989 and focus on the child's welfare, which may override any private agreement. However, co-parenting agreements can still be useful as a record of intentions.
Parental responsibility (PR) — the legal right to make decisions about a child's upbringing — is automatic for birth mothers and for legal fathers/second parents. Others, including known donors who are not legal parents, can be granted PR by agreement or court order, but this does not make them a legal parent.
Storage of gametes in the UK is regulated by the HFEA. Following a 2022 reform, eggs, sperm, and embryos can be stored for up to 55 years (previously 10 years), provided consent is renewed every 10 years. This is one of the most favourable storage frameworks in Europe.
Surrogacy in the UK is legal but unenforceable by contract — surrogacy agreements cannot be enforced in court. The surrogate is the legal mother at birth, and a parental order must be obtained after the birth to transfer legal parenthood to the intended parents. Reform of surrogacy law is underway as of 2024.
Scotland, England and Wales, and Northern Ireland have slightly different procedural rules, though the core framework under the HFEA applies across Great Britain. Legal advice specific to the relevant jurisdiction within the UK is advisable for complex arrangements.
