Massachusetts uses Legal custody and physical custody; parenting plans detail decision-making and parenting time.. Courts apply best-interests factors including the child’s needs, each parent’s ability to meet them, the child’s relationship with each parent, and any history of abuse. Shared legal custody is common when parents can cooperate; physical custody follows best interests. That is what separates Massachusetts child custody and parenting time from a generic national summary. Read Mass. Gen. Laws ch. 208, § 31; ch. 209C before the background sections below. Relocation: A parent seeking to remove the child from Massachusetts generally must show the move is in the child’s best interests (Yannas / Rosenthal framework). Modification: A material and substantial change of circumstances is required to modify custody.
