In the case of Arnhold v. McLean, the Appeals Court of Massachusetts dealt with a dispute between Crystal Lee Arnhold and Daniel Ernest McLean. The case primarily revolved around a modification judgment from the Probate and Family Court, which allowed Arnhold, the mother, to relocate to Florida with their two minor children. McLean, the father, appealed this decision, arguing against the relocation and also contesting the denial of joint legal custody. The court’s decision was to affirm the judgment, thereby supporting the mother’s right to move with the children. The case highlights issues of custody and relocation within family law, emphasizing the court’s discretion in such matters.
