Abstract
Due to the constant development of medicine and biotechnology, including the in vitro procedure, more and more infertile couples can fulfil their desire to have a child. Traditional rules of family law concerning the determination of status familiae of such children have then turned out to be insufficient. The situation is even more complicated when IVF procedure assumes the use of donated genetic material or the involvement of a surrogate mother. Therefore in the field of family law the intention to “create” a child starts to play quite an important role. Family law is then undergoing far-reaching transformations, especially in those countries where same-sex couples are eligible to start IVF procedures (Great Britain, USA, Germany, Austria).
