Adopting a partner's child, often called stepchild adoption, addresses a very concrete question: is it possible to give legal recognition to a family relationship that is already important to a minor in daily life? The answer does not depend solely on the duration of the relationship between the adults. What matters is the type of bond between the applicant and the parent, the role actually played toward the minor, the position of the other parent, and, above all, the best interests of the child or girl.
I want to help you distinguish the paths provided by Article 44 of Law no. 184 of 1983, understand why consent and opposition are not formal details, and see what effects the judgment produces. The term "stepchild adoption" is useful for describing the issue, but it does not identify a single procedure: seemingly similar situations may follow different rules.
What Is Stepchild Adoption
It is not an automatic adoption. Special cases adoption creates an adoptive filiation relationship through a judgment by the Juvenile Court. It is not enough to live with the minor, care for them, or agree among adults: the judge must verify that the requested solution corresponds to their overriding interest.
The law uses precise categories. Article 44 of Law no. 184 of 1983 contemplates multiple adoption hypotheses even without a declaration of adoptability. For a partner's child, letter b), which concerns the parent's spouse, and letter d), concerning the established impossibility of pre-adoptive foster care, are central. The text of the article and the general conditions are also reported on the Ministry of Justice page on special cases adoption.
The English name can be misleading. There is no rule according to which any partner can adopt the other's child. If the adults are married, the application may fall under Article 44, paragraph 1, letter b). If instead they are not married, or are in a civil union or cohabiting, the issue must be placed differently: letter d) may become relevant, but only if its prerequisites are met and the adoption truly protects the minor.
The Two Paths Most Frequently Concerning a Partner's Child
The Spouse's Child: Article 44, Letter b)
Marriage is the specific prerequisite. Letter b) allows adoption by the spouse when the minor is the child, even the adopted child, of the other spouse. In this path, the marital relationship is not a secondary element: the Constitutional Court has clarified that it must exist at the time the procedure is initiated and in any case prior to the assent required by law. If the marriage no longer exists before the application, this provision cannot be used.
A fixed age gap is not required. The requirement of a difference of at least eighteen years between the adopter and the adoptee is provided by Article 44 for letters a) and d), not for letter b). However, this does not make the adult's position irrelevant: the court still evaluates the affective, educational, and family suitability of the person asking to adopt.
The Unmarried Partner: Article 44, Letter d)
Letter d) requires something more than a couple's bond. It concerns the established impossibility of pre-adoptive foster care. Jurisprudence has interpreted this impossibility also in a legal sense, not just a material one, allowing the use of special cases adoption to protect a consolidated affective relationship between the minor and their parent's partner when full adoption is not practicable.
The relationship already built with the minor is decisive. The Constitutional Court has traced back to this path both the opposite-sex cohabitant of the biological parent, excluded from letter b) because they are not a spouse, and the same-sex civilly united partner or cohabitant. This is not recognition based solely on the desire to become a parent: a real relationship with the minor and a judicial verification of their interest are required. This development is explained in Constitutional Court Judgment no. 79 of 2022.
The eighteen-year condition remains important. For applications based on letter d), the adopter's age must exceed the minor's age by at least eighteen years. Furthermore, if the applicant is married and not legally separated, in cases governed by letters a), c), and d) the law requires the application of both spouses: it is not possible to ignore an existing marriage to file the petition as if the applicant were single.
Consent, Listening to the Minor, and Parental Opposition
The minor's consent carries a precise weight. Anyone who has reached the age of fourteen must give their consent to the adoption. A minor who has reached the age of twelve must be heard personally; if younger, they must be heard when their capacity to understand and express themselves allows it. Listening is not a decorative step: it allows the judge to consider the minor's identity, relationships, and background.
Article 46 requires the parents’ assent. This requirement is not limited to parents exercising parental responsibility: that distinction becomes decisive when assessing whether a refusal can be overridden. The provision also requires the assent of any spouse of the person to be adopted. It is therefore necessary to identify everyone whose assent is required and distinguish assent, refusal and inability to obtain it because of incapacity or untraceability. See Article 46 of Law no. 184 of 1983.
Opposition cannot be overcome by a simple assessment of opportunity. The Constitutional Court, examining Article 46, highlighted the limit posed by the discipline when refusal comes from the parent who fully exercises responsibility over the minor. For this reason, a couple's crisis can deeply affect the possibility of reaching adoption: the affective relationship between the adopter and the minor remains a relevant fact, but it alone does not replace the prerequisites required by law.
The couple and parenthood do not coincide. Separation between adults does not automatically cancel the relationship built by the minor with their parent's partner. However, if the necessary assent is lacking, it is incorrect to promise that the judge will always override it in the name of the affective bond. The distinction is essential especially when the adoption project is considered after the onset of a conflict.
The Best Interests of the Child Guide the Decision
The judge looks at the minor's actual life. The law requires the Juvenile Court to decide based on the overriding interest of the adoptee. This means verifying whether the relationship with the adopter is stable, whether the adult performs a recognizable caregiving function, whether they know how to assume educational responsibilities, and whether the family environment is adequate for the minor's growth.
Cohabitation is a fact, not a shortcut. Living under the same roof can demonstrate a shared daily life, but it is not enough on its own. Continuity of care, participation in school and healthcare choices, presence in ordinary moments, and the quality of the relationship can assume relevance. Conversely, a recent or intermittent relationship may not offer the stability necessary to establish a new status of child.
The family of origin is not erased. Special cases adoption does not work like full adoption: it preserves the minor's relationships with their family of origin. The Constitutional Court explains that this form of adoption can formalize an pre-existing affective bond without severing original ones. For the minor, therefore, the point is not having to choose between two families, but understanding whether adoption adds coherent protection to their history.
Broader family ties also count. With judgment no. 79 of 2022, the Constitutional Court eliminated the exclusion of civil relations between a minor adopted in special cases and the adopter's relatives. The decision thus also values relationships with grandparents, brothers, sisters, and other family members of the adoptive parent, without eliminating those already existing with the family of origin.
The Effects of the Judgment and What Does Not Change
Adoption attributes a legal bond. When pronounced, it is not limited to recording a de facto relationship: it constitutes an adoptive filiation relationship between the minor and the adopter. This affects the duties and protections deriving from being a child, in addition to giving a legal basis to the family relationship built over time.
It does not automatically replace the pre-existing parent. In special cases adoption, the minor's bond with the family of origin remains firm. For this reason, it is wrong to portray it as a mechanism intended to "erase" the other parent or completely rewrite family history. Its function is to add an adoptive parental relationship when the law and the minor's interest allow it.
The surname requires independent attention. The surname issue should not be resolved in advance with standard formulas. General rules and the minor's identity interest must be read in the concrete situation: age, surname already used, relationship with the family of origin, and presence of brothers or sisters can have an impact. It is not prudent to assume that adoption always entails the same registry solution.
Not all family situations require adoption today. Since 2025, for a child born in Italy to a woman who underwent heterologous medically assisted reproduction abroad, in compliance with local law, together with another woman who gave prior consent to the project and to parental responsibility, judgment no. 68 of 2025 recognizes the status of child of the intentional mother as well. In this specific perimeter, the issue must not be automatically treated as an adoption application under Article 44. The content and limits of the ruling are found in Constitutional Court Judgment no. 68 of 2025.
The Application to the Juvenile Court
The application is filed with the Juvenile Court competent for the place where the minor is located. The petition must indicate the minor concerned, the path invoked, and the reasons why adoption responds to their interest. The court hears the provided subjects, carries out the necessary investigations, and decides with a judgment; there is no identical time for every procedure, because the preliminary investigation changes based on consents, family relations, and requested verifications.
Documents serve to clarify determined facts. The birth certificate, documentation on the relationship between the adults, any assents, and elements illustrating the relationship with the minor are not mere bureaucratic attachments: they help place the application in the correct hypothesis of Article 44. Deposit methods and required documents may vary according to the individual court's instructions.
The mistake to avoid is choosing the article's letter by analogy. Being partners, cohabitants, or civilly united does not automatically equate to being spouses for the purposes of letter b). Similarly, invoking letter d) does not render assent, age difference, and the minor's interest irrelevant. Constitutional Court Judgment no. 315 of 2007 shows why the marital relationship required by letter b) must be present at the relevant moment of the procedure.
Frequently Asked Questions
Can I adopt my partner's child if we are not married?
It is possible only in a path different from letter b. The rule on the spouse's child requires marriage. For a cohabiting partner, even of the same sex, Article 44, letter d) may become relevant, but the established impossibility of pre-adoptive foster care, a consolidated relationship with the minor, the anticipated registry requirement, and a decision favorable to their interest are needed.
Must the minor agree to the adoption?
From fourteen years of age, consent is necessary. Anyone who has reached fourteen must consent to adoption. From twelve years of age, the minor must be heard personally; before this age, they are heard if capable of discernment. Listening allows understanding the meaning that adoption assumes for them, not asking them to choose between adults.
Does the other parent's dissent always block the application?
Dissent can be a decisive obstacle. If it comes from the parent who fully exercises parental responsibility, it cannot be treated as a simple formality that can be overcome because the partner has a good relationship with the minor. First, the legal position of that parent must be identified and which assents the concrete case requires must be verified.
Does the minor lose relationships with their family of origin through adoption?
No, this bond remains. Special cases adoption does not sever relationships with the family of origin. It adds the adoptive relationship without automatically replacing the pre-existing parent. Following judgment no. 79 of 2022, the minor's civil relations with the adopter's relatives are also recognized.
How long does the stepchild adoption procedure take?
There is no duration equal for everyone. The Juvenile Court must acquire assents, hear the minor when provided, and carry out useful investigations to decide on their interest. A conflict between parents, the need for further verifications, or questions on the correct legal path can affect timelines; it is not serious to indicate a certain deadline.
Orienting Yourself Before Filing the Application
The right application starts from the minor's story. Before choosing between letter b) and letter d), it is useful to clarify the relationship between the adults, the existence and position of legal parents, the minor's age, the stability of the relationship built with the adopter, and the family effects intended to be protected.
