Posthumous conception means conceiving with someone's egg, sperm or embryo after they have died.
When someone consents to their eggs, sperm or embryos being stored, they are asked to decide what should happen if they die or become mentally incapable. It is very important that consent to posthumous storage use of eggs, sperm or embryos is given carefully and with sufficient detail, since the consent will be relied on after it is too late to clarify someone's intentions.
As a general rule, posthumous conception is only possible where there is a written signed consent to post-death storage and use (although consents provided before 1 October 2009 only had to be in writing and not signed). Timing is also often an issue, since consent to storage cannot be renewed or extended after the gamete provider has died.
However, there are some rare exceptions to this general rule. For example, Diane Blood fought a renowned legal battle to conceive using her deceased husband's sperm (which had been collected without his consent after he was unexpectedly incapacitated by meningitis). The court ultimately decided that it was an infringement of EU law to deny Mrs Blood her right to seek treatment elsewhere in Europe. Although treatment could not lawfully take place in the UK, the HFEA allowed Mrs Blood to export her husband's sperm to Belgium where she was successfully treated.
If stored eggs are used to conceive a child after the egg provider has died (usually through a surrogacy arrangement), she (or he/they, if trans) will not be a legal parent. In line with the general law on parenthood, whoever gives birth to the child is treated as the legal mother.
If sperm is used to conceive a child after the sperm provider has died, the position is a little more complex. When the laws on parenthood were first passed in 1990, they made clear that any man who conceived a child posthumously would not be treated as the legal father. The reason for this was to prevent practical difficulties; for example, an estate could not be wound up if there remained a possibility that someone could have a legal child in the future who might have a claim to a share of the assets. However, in 2003, it was recognised that men conceiving posthumously should be acknowledged as the fathers of their children. The law was amended to allow a father conceiving posthumously to be named as the father on his child's birth certificate.
This has left a rather complex set of rules on parenthood in posthumous conception cases:
If a father dies when his wife or partner is pregnant, he is treated as the father for all legal purposes, including property rights and inheritance. This applies both where he is the biological father and in certain circumstances where donor sperm has been used.
If a woman is inseminated with her husband or partner's sperm after his death, or if embryos are transferred to her after his death that are either created with his sperm or created with donor sperm before he died, he can be named on the birth certificate if his wife or partner makes a special written election within 42 days of the birth. However, he is not the legal father for any purpose other than naming him on the birth certificate. If a woman is inseminated with donor sperm after her husband or partner's death, or if embryos are transferred to her that were created with donor sperm after his death, the man is not the father for any purpose and cannot be named on the birth certificate.
The Human Fertilisation and Embryology Act 2008 introduced parallel provisions for same-sex partners where a surviving partner conceives after her partner's death (after 6 April 2009) and these provide that:
It is not yet known how any of these rules would apply in a case involving a trans parent, and this is a complex legal question as the law stands because the wording of the statute is gender-specific.
