(1) A person of full age may be adopted if the adoption is morally justified; this is to be assumed in particular if a parent-child relationship has already developed between the adoptive parent and the person to be adopted.
(2) The adoption of persons of full age is governed accordingly by the provisions on the adoption of minors, unless the following provisions lead to a different conclusion. The adoption of a married person or of a person who is a partner in a life partnership requires consent by their spouse or their life partner. The change of the birth name extends to the married name or the name for the life partnership of the person adopted only if the spouse or life partner also agrees with and accepts the change of name, before the pronouncement of the adoption, by declaration to the family court; the declaration must be publicly certified.
