For people who conceive a child in private donation arrangements, without going through a fertility clinic, none of those rules explained above about donation or registration of information apply, and you can’t get your information included on the HART register.
The people involved need to come to their own agreements about sharing information, and about how many children can be conceived using sperm from the same donor – but these arrangements are not legally enforceable.
It is a good idea to write down any medical and family information about the donor that the family wants to be available to the child later on.
