The case of Cavanagh v. Cavanagh, decided by the Supreme Judicial Court of Massachusetts, involves a divorce and subsequent modification proceedings between Michael and Lynn Cavanagh. The couple, who were married for approximately twenty-one years, had three sons. During their marriage, Michael worked as a physician’s assistant, while Lynn was primarily a homemaker. The divorce judgment included a separation agreement that was merged into the judgment. The case became notable for its examination of alimony and child support calculations, particularly when both are requested simultaneously. The court criticized the trial judge for not conducting a detailed analysis of the family’s circumstances as required by law before denying alimony. The decision also provided guidance on the types of income to be included in child support calculations, such as employer contributions to retirement plans and interest income. Additionally, the court addressed the interpretation of ambiguous provisions in separation agreements and emphasized the importance of including the divorce judgment in the record for appellate review. The case highlights the complexities of family law, particularly in the context of financial support and the interpretation of separation agreements.
