Best Interest of the Child
What "Best Interest of the Child" Means
The 'best interest of the child" standards is the guiding principle used by family courts when making custody and parenting-time decisions. It focuses on protecting a child's health, emotional wellbeing, safety, stability, and ability to maintain strong relationships with both parents.
​
This standard is intentionally broad, allowing judges to consider the unique circumstances of each family.
Key Factors Courts Consider
Although each state defines its own “best interest” factors, most courts evaluate the same core elements, including:​
​
-
The child's safety and wellbeing
-
Each Parents ability to meet daily needs (medical, educational, emotional)
-
The child's relationship with each parent
-
The stability of each home environment
-
Each parent's history of caregiving and involvement
-
Any history of domestic violence, abuse, or neglect
-
How well each parent supports the child's relationship with the other parent
-
The child's developmental needs and, in some states, the child's preference
​
How these factors are defined and applied depends on state law. For examples of how courts articulate and apply the best-interest standard, see our state guides for California, Texas, Florida, New York, and Illinois.
​
These factors help courts design parenting plans that support long-term stability and strong parent-child relationships.
What This Means for Parents
The best-interest standard is the central legal principle courts use to guide custody and parenting-time decisions. In practice, courts consider a range of factors that relate to a child’s health, safety, emotional wellbeing, stability, and relationships with caregivers. These factors may include routines, communication patterns, conflict levels, and caregiving quality, among others. The specific application of these considerations varies by jurisdiction and individual family circumstances.

Courts are not looking for perfect parents - they are looking for safe, stable, supportive environments that meet the child's needs.
Quick Takeaway
The best-interest standard shapes custody decisions nationwide. When parents understand how courts apply this principle, they can make clearer decisions, reduce conflict, and build plans that genuinely support their child’s well-being.
