The right to know one's parents is considered to be of key importance to forming one's own identity. It is acknowledged by international treaties, whereas the Constitutional Court of the Republic of Slovenia has also acknowledged it as having the nature of a fundamental human right. Situations in which the desire to know one's biological parents are the following: adoption, treatments for assisted human reproduction with a donated germ cell, and all other situations where a child does not know his/her genetic parents. The first condition for exercising this right is that the child even knows that a parent who shares a genetic link to him/her exists. In cases of adoption and assisted human reproduction with a donated germ cell, a further condition is that there exists the documentation that entails information about the child's parents. The third condition is the possibility of access to such information. In all other instances where a child does not know his/her parentry, and wishes to know them, the law must provide him/her with effective judicial protection (e.g. a paternity suit). Although it is possible to detect a growing trend of the desire to know one's own parents, the Slovenian legislation does not keep up the pace as well as it could, especially in the field of assisted human reproduction with a donated germ cell where complete anonymity of donors still applies.
