What this means in practice

A child's preference is rarely the only thing a court looks at. Judges also weigh each parent's ability to care for the child, the child's ties to home, school and community, and any history of abuse or conflict. A clear preference from an older, mature child can carry real weight, but it does not replace the best interests test.

Courts often hear from children privately, for example in a judge's chambers, through a guardian ad litem, or through a custody evaluator, rather than on the witness stand. The process and who may be present depend on local court rules and the judge's discretion.

Courts look closely at whether a preference is the child's own view or the result of pressure from a parent. Coaching a child or promising rewards for choosing a side can hurt a parent's case. Parents who reach their own arrangement can record it in a parenting plan or settlement agreement for the court to review.
