Child custody disputes can become particularly difficult when one parent believes the other parent is incapable of safely or responsibly caring for their child. A parent may describe the other as “unfit,” but under Massachusetts law, parental fitness involves much more than disagreements over parenting styles, household rules, relationships, or personal choices.
Massachusetts courts generally focus on the best interests, happiness, and welfare of the child when making custody decisions. When serious concerns about a parent's ability to care for a child arise, the court may consider whether that parent's conduct, circumstances, or limitations place the child's physical or emotional well-being at risk.
Understanding what may constitute parental unfitness—and what generally does not—can be important for parents involved in a contested custody matter.
