There’s different rules about what if anything the law allows adults who have been told or discovered they were born from sperm or egg donation to discover about the donor, including if the donor's name is part of what they can find out. The rights to information depend on when the person was born. There’s a link here that explains it by year of birth: www.dcnetwork.org/solo-mums/your-childs-rights
People born through surrogacy don’t seem to automatically have any rights to get information about whose egg, sperm, or embryo were used for their birth or to know who was pregnant and gave birth to them, depending on how their conception and subsequent legal arrangements happened.
It’s complicated because of all the variables in arrangements between the adults before the birth and afterwards but The Law commission full consultation document has a whole chapter (chapter 10) about the child’s information rights that is worth reading. It describes problems like genetic links from surrogate to child via her egg not always being recorded. Or the original birth certificate records not always being legally available to the person to access, even if they ask for them.
‘10.38: As we mention above, it appears that, contrary to the position on adoption, it is not possible in England and Wales for a person born as a result of a surrogacy arrangement to access their original birth record. The General Register Office agree that, under the current law, it is not possible for it to provide the linking information that would allow a child born of surrogacy to obtain their original birth certificate.’
They also quote academic research that says that parents are more likely to tell their child that they were born from a surrogate than they were to tell them that donor egg or sperm were used, including when they’d been born from the surrogates’ own egg.
The Law Commission suggested legal changes to give new information rights and consistent record keeping. This would include where no IVF was used in the surrogacy. It’s good the law commission covered this because there’s clearly a serious problem when key information isn’t recorded at all, or it has been recorded somewhere but isn’t accessible to people. None of this would cover surrogacy from other countries, though which would bring up all the same questions.
