When adoption is mentioned, most people think of minors finding a new family. However, the law also allows for the legal formalization of emotional bonds between adults through the institution of adult adoption. This modality, although less well-known, has a solid legal foundation and responds to personal realities that fall outside the traditional model of filiation.
This form of adoption is not designed to address the guardianship or care needs typical of childhood, but rather to legally recognize already established emotional bonds. In many cases, these are relationships of support and prolonged cohabitation where there is no biological kinship, but there is a firm desire to create a family bond recognized by law.
Various reasons may exist: from the desire to legally recognize a caregiving relationship not formalized at the time, to the recognition of a paternal or maternal figure who has been present in later stages of life. What is important is that the adoption responds to a free and conscious decision by both parties and not to a need for protection as occurs with minors.
Legal Framework: As Established by the Civil Code
The legal framework supporting the adoption of adults is explicitly outlined in Articles 175 and following of the Spanish Civil Code.
This regulation recognizes the uniqueness of establishing filial bonds with individuals who have already reached full legal capacity, differing substantially from the procedure provided for the adoption of minors. In this context, the mandatory intervention of social services and the performance of comprehensive psychological assessments are dispensed with. This distinction lies in the legal presumption that the adoptee, being of legal age, possesses the maturity and discernment necessary to understand and freely consent to the creation of a filial bond with another person.
The law places trust in the autonomy of the adult’s will, considering that their decision to establish this filial bond responds to an informed and conscious choice, without the need for the guardianship and additional guarantees required in protecting the rights and interests of minors.
Requirements for the Adoption of Adults
Although simpler than the adoption process for minors, this institution is also subject to certain essential requirements:
- The adoptee must be of legal age. This is the starting point, as it specifically involves formalizing a relationship with a legally capable person.
- Free consent of both parties. Both the adopter and the adoptee must give their consent expressly before the judicial authority, without external pressure.
- Minimum age of the adopter. The law requires that the adopter be at least 25 years old.
- Appropriate age difference. A generational difference of at least 16 years between adopter and adoptee is necessary, maintaining the coherence of the parental relationship.
- Prior cohabitation in certain cases. If the adoptee is an emancipated minor or an adult who has lived stably for at least one year with the adopter, Article 175.2 of the Civil Code allows this cohabitation to be taken into account as a basis for adoption.
- Legitimate motivation. Although no specific cause is required, the judge may assess the reasons driving the adoption to prevent possible fraud or interests unrelated to the recognition of a genuine emotional bond.
Legal Procedure
The adoption of an adult is initiated by filing a petition with the court of first instance in the place of residence of the adopter or the adoptee. It must be accompanied by documentation proving compliance with legal requirements: birth certificates, national identity documents, and where applicable, proof of cohabitation.
If everything is in order, the judge will issue an Order approving the adoption and making it fully valid.
Legal Consequences
- Creation of a full filiation relationship. Adoption creates between the parties a family bond with legal effects comparable to those of natural filiation: maintenance obligations, inheritance rights, etc.
- Modification or termination of prior bonds. Generally, adoption implies the termination of legal ties with the biological family, although in the case of adults some type of bond may be maintained, especially in succession matters, if the judge so decides.
- Change of surnames. The adoptee may acquire the surnames of the adopter, in accordance with general filiation rules, which also has implications in terms of civil identity.
Success Story: In Diem Abogados—Experts in Family Law. Adoption by Adults of Legal Age
In a moving example of how the law can formalize deep emotional bonds, there was the case of a nephew who, after losing his father, found in his uncle not only a relative, but a paternal figure willing to provide the filial protection he needed.
Adoption in this scenario transcended the mere blood relationship, allowing the uncle to legally assume the role of father, granting the nephew not only a surname and inheritance rights, but also the legal security and social recognition of a paternal bond that already existed emotionally.
This real case illustrates how adult adoption can be a powerful instrument to consolidate pre-existing family relationships, offering emotional and legal stability in moments of vulnerability and loss, and transforming a collateral kinship bond into a direct filial relationship.
A Legal Tool at the Service of Emotional Reality
Adult adoption allows the law to adapt to new ways of understanding family. It is not about replacing biological filiation, but about legally recognizing relationships that have been born and grown outside blood ties.
From a professional perspective, it is essential to understand this institution in order to properly advise those seeking to formalize this type of bond. The legal certainty it provides can be fundamental in aspects such as inheritance, civil status, or legal representation in certain circumstances.
In short, adoption between adults is not only possible, but represents an act of mutual recognition charged with humanity and legal meaning. A legal instrument at the service of affection, demonstrating that the concept of family can go far beyond the biological and the conventional.
