How Courts Determine the ‘Best Interests of the Child’ Standard

When a family court decides where a child will live or how parenting time will be shared, one legal standard guides the decision, and that is the best interests of the child. For parents going through a custody proceeding in Virginia, understanding what that standard actually means, and what judges are looking for, can help you prepare.

What the Standard Means in Practice

Courts use the “best interests of the child” standard to decide custody and visitation. The principle is straightforward. Custody decisions should center on the child’s needs, not the preferences or convenience of either parent.

In Virginia, the factors judges must weigh are listed in Virginia Code § 20-124.3. There are ten of them, and courts consider them together, deciding how to weigh each factor in each case. No one factor is weighed more than another in every case. Considerations include the physical and mental health of the child and each parent, the quality of each parent’s relationship with the child, connections to siblings and community, each parent’s role in daily caregiving, and each parent’s willingness to support the child’s relationship with the other parent.

A history of family abuse, child abuse, or sexual abuse is a factor that the court can consider and often weighs as more important than any other element when it is a part of the case.

Will My Child Have a Say?

One of the most common assumptions in custody cases is that a child can choose which parent to live with once they reach a certain age. The reality is that it depends. Virginia law allows courts to consider a child’s preference, but only when the child is old enough and mature enough to first understand the difference between a truth and lie, and second, the child is of sufficient maturity to express his or her concerns to the court. There is no set age for this. It is left to the judge’s discretion.

Even then, a child’s preference is one factor among many. A judge will not place a child with a preferred parent if other evidence suggests that their preference is not what is in their best interest. In most cases, a child’s wishes are communicated through a guardian ad litem or therapist rather than direct testimony, which helps reduce the pressure on the child. 

How Parental Fitness Is Assessed

Parental fitness comes down to whether you can consistently and safely assess and meet your child’s needs. Courts look at mental and physical health, parenting history, and substance abuse concerns. They also look at documentation including school involvement, medical appointments, and daily routines. A parent who can show documented, steady involvement in their child’s life carries real credibility with a judge. The court will notice if a parent only started showing up once Court proceedings began.

Custody Evaluations and the Role of the GAL

In some cases, the court appoints professionals to provide additional insight. A custody evaluator, typically a licensed psychologist, interviews both parents and the child, reviews records, and observes family interactions. A guardian ad litem (GAL) is an attorney appointed to represent the child’s best interests.

The GAL submits a written recommendation and appears at trial with the same powers to call witnesses and present evidence as each party’s attorney.  The GAL may also provide oral advocacy for the child or children in the case.  Judges typically give the GAL’s recommendation significant weight. A custody evaluation is also a written document usually presented by one or both parties to the court. It is typical for the custody evaluator to testify, usually speaking as to both parents’ roles, and make recommendations to the court based on their clinical observations and testing. However, neither the custody evaluator nor the GAL makes the final decision. That remains with the judge.

Why the Status Quo Matters

Courts are reluctant to disrupt a child’s established routines without good reason. If your child is thriving in a particular school, connected to friends and extended family, and settled into consistent daily routines, a judge will think carefully before changing those arrangements.

The status quo is not just about keeping the child in the same house. It includes caregiving patterns, school continuity, friendships, and community ties. A parent who can demonstrate that kind of consistency often has a meaningful advantage.

Common Misconceptions

There are several widely held assumptions about custody that do not hold up in court.

1. Mothers do not automatically win custody. Virginia applies the best interests standard in a gender-neutral manner. Neither parent is presumed better suited based on gender alone.
2. Children cannot simply choose where they live; even older teenagers cannot make that decision unilaterally. Their preference may be considered, but the court has the final say.
3. Income does not decide custody. Courts focus on parenting capacity and the child’s well-being, not financial status.
4. You don’t have to have a separate bedroom for each child. In today’s economic climate children may have to share rooms; the Court does not require parents to have separate rooms for each child regardless of financial limitations.

How to Prepare

The court’s decision is ultimately out of your hands, but how you prepare for it is not.

• Document your involvement. School pickups, medical appointments, extracurricular activities. Keep a record. Calendars, emails, and receipts all count.
• Keep communication civil. Courts pay close attention to how parents interact. Negative behavior toward the other parent, especially in front of the child, can hurt your case.
• Stay consistent. Show up reliably for your parenting time and stay engaged in your child’s daily life. Do not change the schedule for personal or work matters constantly and force the other parent to accommodate your frequent last-minute schedule changes.
• Work with a family law attorney. An attorney can help you understand which factors carry the most weight in your specific situation and how to present your case clearly.
