If the child is born in England or Wales, it is the responsibility of the surrogate to register the birth. She will be registered as the mother and her civil partner/spouse will be registered as the second parent.
If the surrogate is not married or in a civil partnership, the other legal parent can be included on the birth certificate provided he or she attends the birth registration. If, however, the intended parent is not the biological father, he/she will need to bring with them the HFEA forms nominating them as the second parent. Such forms need to be executed and signed prior to conception.
