Adoption and the existing figure in Colombia for registering the children of same-sex couples with the data of both parents apply to different cases.

Adoption: proceeds when a person outside the couple who decided to have a child wishes to be linked as the child's parent. An example is when a person with a child from a previous relationship forms a family with another person who establishes a parental relationship with his or her child. In this case, if this new person wants to establish a legal bond with his or her partner's child, he or she must go through an adoption procedure. 

Civil registration of children: is the name given to the registration of the birth of a child by both parents. It applies when the birth of the child is the result of a joint decision of the same-sex couple to undergo assisted reproductive treatment. In other words, only when a child is born to a married or unmarried couple can both parents be directly included in the birth registration of a child.
