Divorce and Parental Responsibilities: A Legal Overview When Minors Are Involved

This overview aims to assist individuals considering divorce or already in the process of separating and having children. Proper legal guidance is key to ensuring that parental responsibilities are exercised in a manner that provides stability and clarity for both parents and, most importantly, protects the rights and interests of the child.
In Portugal, divorce proceedings involving minors require particular attention to matters that go well beyond the dissolution of the marital bond. One of the key legal components in such cases is the regulation of parental responsibilities (responsabilidades parentais), which encompasses the rights and duties of both parents concerning the upbringing, care and overall well-being of their children. Portuguese law recognises the importance of both parents maintaining an active role in the child’s life, even after the end of the marital relationship. As a rule, parental responsibilities are exercised jointly by both parents, except in cases where the court determines otherwise based on the best interests of the child (superior interesse da criança). This includes decisions concerning education, healthcare and the determination of the child’s habitual residence.
When a divorce involves minors, it is mandatory to establish a clear legal framework that governs the exercise of parental responsibilities. This includes defining the child’s living arrangements, such as whether there will be alternating residence or primary residence with one parent, the visitation schedule applicable to the non-resident parent, and the financial obligations of each parent with respect to child maintenance (prestação de alimentos). The agreement or decision must also clarify how major decisions concerning the child will be made and whether those decisions will continue to be taken jointly or, in specific cases, by only one of the parents.
In Portugal, there are two types of divorce: divorce by mutual consent (divórcio por mútuo consentimento), which is an administrative procedure handled by the Civil Registry Office when both spouses agree on the divorce and all related matters, including parental responsibilities; and divorce without the consent of one of the spouses (divórcio sem consentimento de um dos cônjuges), which is a judicial procedure that takes place in court and may involve disputes regarding the reasons for the divorce or the regulation of responsibilities towards children. In either case, whenever children are involved, the regulation of parental responsibilities must be analysed by the Public Prosecutor’s Office (Ministério Público), even in mutual consent divorces.
In situations where the parents reach a mutual understanding, they may submit an agreement regulating these matters, which will be subject to assessment by the Public Prosecutor’s Office. The agreement will only be approved if it is considered to safeguard the best interests of the child. In the absence of agreement, or cases involving conflict or potential harm to the child, the court will intervene and define the terms of the regulation, always guided by that principle.
The regulation of parental responsibilities is required not only in the context of divorce but also in cases of legal separation, annulment or when the parents were never married. The law makes no distinction between marital and non-marital children in this regard. What matters is the child’s protection and access to a stable and safe environment, supported by both parents to the extent possible.
It is also important to note that the law provides for different types of parental responsibility arrangements. The most common model is joint parental responsibility (responsabilidades parentais conjuntas), where both parents remain equally involved in decisions about the child’s life, even if the child primarily resides with one of them. In some situations, the court may establish exclusive parental responsibility (responsabilidades parentais exclusivas), assigning decision-making authority to only one parent, usually when there is conflict or absence of the other parent, or when shared responsibility would not serve the child’s best interest.
Common disputes in these matters include disagreements over where the child should live, the frequency and logistics of visitation, financial contributions from one or both parents, and the involvement of extended family members. In certain cases, accusations of parental alienation, neglect or domestic violence may also arise and must be handled with sensitivity and legal precision. These factors can heavily influence the outcome of the court’s decision and may lead to supervised visitation or limited contact.
The Public Prosecutor plays a crucial role in all family law proceedings involving minors. Whether the process is consensual or litigated, the Ministério Público must be heard to ensure that the proposed arrangements protect the child’s fundamental rights. In consensual proceedings, the Public Prosecutor may oppose the parents’ agreement if it is deemed insufficient or inadequate. In litigious cases, the prosecutor may also present evidence and arguments to guide the court in reaching a decision aligned with the child’s best interest.
Parents are strongly encouraged to seek legal advice early in the process. Reaching a well-structured agreement is often preferable to engaging in a lengthy court dispute, particularly when children are involved. Mediation and alternative dispute resolution methods may also be considered and are promoted in Portugal as effective tools to support parents in conflict while protecting the emotional well-being of their children.
At the end of a divorce or separation process, the resulting decision or agreement will be reflected in a court order that becomes legally binding. Non-compliance with that decision can lead to enforcement proceedings, including the intervention of child protection authorities or law enforcement in severe cases. It is therefore critical that all parties understand and commit to the arrangements established, and that any future changes in circumstances are brought to court to request a formal revision.
