Sun Life Assurance Co. of Canada v. Sullivan

# Sun Life Assurance Co. of Canada v. Sullivan **What Happened** Thomas Sullivan and Mary Anne Sullivan divorced. Their divorce agreement stated that Thomas had to keep Mary Anne listed as the beneficiary on his life insurance policy through his employer, Townsend Oil Co. When Thomas died, a dispute arose over who should receive the insurance money—Mary Anne (as the divorce agreement required) or someone else. **What the Court Decided** The court ruled against Mary Anne Sullivan. The judge found that federal law about employee benefits takes priority over state divorce laws. Even though the divorce agreement said Thomas must maintain the insurance for Mary Anne, she could not claim the money because federal law controlled the insurance arrangement. **Why This Matters for Workers** This case shows that employee benefits—like life insurance through your job—follow federal rules that can override personal agreements. Workers should understand that divorce settlements about employer-sponsored benefits may not always be enforceable. If you're getting divorced and want protection through workplace insurance, consult a professional about how federal benefits laws might affect your agreement.
