What Is Parental Alienation

Law 12,318/2010 defines parental alienation as interference in a child’s or adolescent’s psychological development promoted or induced by one parent, grandparents, or anyone who has the child under their authority, custody, or supervision, causing the child to reject a parent or harming the establishment or maintenance of emotional bonds (art. 2).

Typical Conduct (Art. 2, Sole Paragraph)

The law lists conduct characterizing parental alienation:

Smear campaign — discrediting the parent’s conduct in exercising parenthood
Obstructing contact — hindering the exercise of parental authority and cohabitation
Hindering visitation — preventing or making difficult family contact with the other parent
Withholding information — hiding information about the child (school, health, activities)
False accusations — filing false reports against the parent or relatives to prevent contact
Unjustified relocation — changing address to hinder visitation without justification
Identity alteration — changing the child’s information to make it difficult for the parent to locate them

How to Identify Parental Alienation

Signs in the Child

Unjustified refusal of contact with one parent
Adult language when criticizing the alienated parent
Describing events they did not experience (false memories)
Disproportionate fear or anger toward the alienated parent
Sudden behavioral changes after time with the alienator
Guilt when showing affection for the alienated parent
Unconditional siding with one parent
Extending rejection to the alienated parent’s relatives (grandparents, uncles)

Signs in the Alienator

Constant interference with visitation schedules
Derogatory comments about the other parent in the child’s presence
Excessive control of communication between child and alienated parent
Using the child as a messenger for conflicts
Dramatizing situations to damage the other parent’s image
Preventing the other parent from participating in school and medical activities

Important Differentiation

Not all resistance by a child to contact with a parent constitutes parental alienation. It is essential to differentiate:

Situation	Characteristic
Parental alienation	Child influenced, no real reason for rejection
Actual abuse or neglect	Child rejects based on legitimate experience
Natural parental conflict	Child affected by family stress
Parent preference	Normal in certain developmental stages

Expert evaluation is essential to distinguish these situations and avoid incorrect diagnoses.

Judicial Procedure

Standing to Act

The following may request a declaration of parental alienation:

The alienated parent
Grandparents or affected family members
The Public Prosecutor
The adolescent themselves (with assistance)

Proceedings

Initial petition with account of facts and request for measures
Urgent relief — the judge may order immediate measures (art. 4)
Psychological or biopsychosocial expert evaluation — by a multidisciplinary team
Expert evaluation deadline: 90 days, extendable by court authorization
Hearing of parties and witnesses
Judgment — declaration of alienation and application of sanctions

Psychological Expert Evaluation

Expert evaluation is the primary means of proof in parental alienation cases. It must be conducted by a qualified professional or multidisciplinary team trained in psychology, social work, or psychiatry.

Methodology:

Individual interviews with each parent
Interviews with the child (in an appropriate setting)
Observation of parent-child interaction
Psychological testing
Analysis of documents and records
Interviews with involved professionals (school, doctor)

Sanctions Under the Law

Art. 6 of Law 12,318/2010 provides sanctions applicable cumulatively or separately, according to severity:

Available Measures

Warning — judicial declaration that the conduct is unlawful
Expanded visitation — increased time with the alienated parent
Fine — amount set by the judge as a coercive measure
Psychological counseling — mandatory for the alienator and/or child
Custody change — transfer of custody to the alienated parent
Suspension of parental authority — extreme measure for severe cases

Sanction Graduation

Severity	Typical Sanction
Mild (first incident)	Warning + psychological counseling
Moderate (repetition)	Fine + expanded visitation
Severe (systematic)	Custody change
Very severe (false accusations)	Suspension of parental authority

Urgent Relief

Art. 4 of Law 12,318/2010, combined with art. 300 of the CPC, allows the judge to grant urgent relief in parental alienation cases to:

Guarantee minimum visitation with the alienated parent
Order immediate psychological counseling
Prevent relocation
Establish fines for non-compliance
Set a provisional visitation schedule

Relief may be granted inaudita altera parte (without hearing the other side) when there is imminent risk to the child’s psychological well-being.

Parental Alienation and Joint Custody

Parental alienation is frequently associated with sole custody, where the custodial parent uses their position to distance the child from the other parent. Joint custody, established as the rule by Law 13,058/2014, is viewed as a preventive factor against parental alienation because it:

Balances both parents’ participation
Reduces unilateral power over the child
Maintains regular bonds with both parents
Makes it harder to implement smear campaigns

False Abuse Accusations

One of the most serious aspects of parental alienation is filing false accusations of sexual abuse or mistreatment against the alienated parent. This conduct:

Is classified as a form of parental alienation (art. 2, VII)
May constitute the crime of false accusation (art. 339, Criminal Code)
May constitute the crime of slander (art. 138, Criminal Code)
Justifies immediate custody change
Creates a right to moral damages compensation for the falsely accused parent

Psychological expert evaluation is essential to distinguish false accusations from genuine ones, protecting both the child and the unjustly accused parent.

Preventing Parental Alienation

Practical Measures

Maintain respectful communication with the other parent
Avoid negative comments about the other parent in front of children
Strictly comply with the visitation schedule
Share information about school, health, and activities
Seek family mediation for conflicts
Respect court decisions on custody and visitation

Family Mediation

Mediation is an effective tool for preventing and resolving conflicts that could escalate to parental alienation. The mediator helps parents establish functional communication focused on the children’s interests.

If you identify signs of parental alienation, it is essential to seek specialized family law guidance immediately. An attorney can:

Assess the situation and identify alienating conduct
Request urgent relief to guarantee visitation
Request a court-ordered psychological evaluation
Produce appropriate evidence (documents, witnesses)
Request sanctions against the alienator
Seek custody modification if necessary
