Apply for adoption of an adult

You can adopt a person of full age as a child if you wish to establish a parent-child relationship with the person and this is morally justified. This is assumed in particular if a parent-child relationship already exists between you as the adopter and the adult person; for example, in the case of a stepchild or foster child. If such a relationship does not yet exist, there must be such a strong emotional bond that a relationship similar to the parent-child relationship can be expected. In addition, the adoption must appear morally justified in view of the purpose pursued by it. This means that the adoption request must not violate a moral prohibition and/or must not exclusively pursue a material purpose, such as avoiding inheritance tax or establishing a right of residence.

In order to adopt the adult person as a family member, you and the person concerned must file an application with the family court.

The adult adoption is basically an adoption with weak effect. This means that the adopted adult's family relationship with his or her biological family is not cancelled, only the newly created relationship with the adopters is added.

Under certain conditions and upon application, an adoption with more far-reaching legal consequences, as they apply to the adoption of minors, is also possible. This is then also referred to as a "full adoption" or adoption with "strong effect". This would result in an almost complete legal integration of the adult into your family. This means that the relationship and thus, among other things, all inheritance and maintenance obligations to the natural parents are cancelled. In the case of a stepchild adoption, this does not apply to the continuing relationship to the remaining parent.

Requirements

• You may adopt an adult person as a child if the adoption is morally justified. In other words, the adoption request is based on an existing parent-child relationship or a comparably strong inner bond and does not violate a moral prohibition and/or does not exclusively pursue a material purpose. This is the case, for example, if the person to be adopted has already lived in your family as a minor child.
• The adoption must not conflict with the overriding interests of third parties, for example your biological children.
• According to case law, there should generally be an age difference corresponding to a parent-child relationship (at least 15 years).
• The applications and any necessary consents (for example, of the spouses) must be in notarized form.

What documents do I need?

• Notarized application
  

  Notarized application of the adopter and the adult. The applications must not be bound by any condition or time provision.

• Notarized declaration of consent
  

  If the adopter or adoptee is married or in a civil union, a notarized declaration of consent from the spouse or civil partner is required.

• Other required documents
  

  The family court may request other necessary documents. For example, proof of civil status (such as birth or marriage certificates).
