Child custody – What is meant by the best interests of the child?

When parents separate, questions quickly arise about permanent residence, visitation, and parental responsibility. In all such cases, there is one legal principle that weighs most heavily: the best interests of the child .

But what does the best interests of the child mean in practice – and how is it assessed in a child custody case?

This article provides a thorough and professionally grounded review of what the law says, which assessment factors are central, and what is decisive if the case is heard in court.

‍

What is in the child's best interest?

The best interests of the child are a statutory principle in the Children's Act . This means that all decisions about children after a breakup should be based on what is best for the child overall, and not the wishes of the parents.

The principle is also anchored in the UN Convention on the Rights of the Child , which applies as Norwegian law. The Convention states that the best interests of the child shall be a fundamental consideration in all actions affecting children.

There is no standard solution that is automatically considered correct. The assessment must always be:

• Concretely
• Individual
• Holistic

Two children in seemingly similar situations may therefore receive different solutions, because the child's age, maturity, attachment and needs vary.

‍

How is the best interests of the child assessed in a child custody case?

The court makes an overall assessment that includes several factors. No single factor is decisive on its own.

‍

1. Stability and continuity

Stability is a weighty consideration in Norwegian case law. The court considers, among other things:

• Who has had the daily care?
• Where the child has had their primary home
• Connection to local community, school and friends
• Risk of rupture in established relationships

Continuity is often particularly important for younger children. Here you can read what applies to child custody when the children are young.

‍

2. Parents' ability to care

The parents' ability to care is assessed broadly and includes:

• Ability to provide emotional support
• Ability to create structure and predictability
• Boundary setting and safety
• Mental stability
• Ability to shield the child from conflict

A key part of the assessment is also the parents' ability to cooperate . If one parent actively opposes the child's contact with the other, this may weaken that person's case.

‍

3. The child's right to participation

Children have the right to be heard in matters that concern them. According to the Children's Act, children who are capable of forming their own views shall be given the opportunity to express their views.

The older and more mature the child is, the greater the weight the child's opinion is given.

Nevertheless, it is important to clarify: The child does not have decision-making authority. The court must make an independent assessment of what is best.

‍

4. Risk, violence and other stresses

If there is:

• Violence or threats
• Drug problems
• Serious mental illness
• High and persistent level of conflict

This could be of decisive importance. The child's need for security and protection takes precedence over considerations of equal distribution or the parents' wishes. In cases involving allegations of violence, the court conducts a special risk assessment.

‍

Shared permanent residence – when is it in the best interests of the child?

Shared permanent residence means that the child lives permanently with both parents and that decisions are made jointly. In this article you can read more about the different distribution models.

The court considers, among other things:

• Do the parents live close to each other?
• Are they able to cooperate?
• Can the child tolerate frequent transitions?
• Does the child want such a solution?

If the conflict is high, shared housing can create more stress than security.

‍

Typical misconceptions about the best interests of the child

There are several common misconceptions:

‍

"The child should always live mostly with the mother."

There is no such general rule. Parents are legally equal.

‍

“Equal time is always fairest.”

Fairness between parents is not the issue of assessment. What is crucial is the child's needs.

‍

"The child can choose freely when he turns 12."

The child's opinion should be given great weight from this age, but the court makes the final decision.

‍

What happens if the parents don't agree?

Before the case can be brought to court, the parents must attend mediation. If mediation does not lead to progress, the case can be taken to court.

The court may:

• Appoint an expert psychologist
• Conduct conversations with the child
• Obtain documentation
• Hold the main hearing

The process can be both legally and emotionally demanding.

Summary

The best interests of the child is a legal standard that requires a concrete and forward-looking overall assessment in each individual case. Important points are:

• Stability and continuity
• Caring ability
• Cooperation
• The child's opinion
• Risk and safety

In child custody cases, it is not the parents' rights that are at the center - it is the child's need for security, development and predictability.
