Frequently Asked Questions
How is child custody decided?
Courts use the 'best interests of the child' standard, considering: each parent's relationship with the child, stability of home environment, child's wishes (if old enough), parental fitness, and willingness to co-parent. Courts increasingly favor joint custody arrangements.
Can I modify a custody agreement?
Yes, if there's been a 'material change in circumstances' since the original order — such as relocation, remarriage, job change, substance abuse, or the child's changing needs. You'll need to petition the court and demonstrate the change benefits the child.
