My step mother was married to a police officer, they had 2 children. He was killed & she has been receiving money from the county he worked in for over 30 yrs. She married my father in 1992 & he passed away on July 1, 2013. So she kept the fact she was legally married a secret to collect money off her deceased husband. She knew once she let the state & county know she was married all the benefits she received from he deceased husband would end. I believe she is the primary benefactor on all my fathers financial affairs. Can she legally obtain that money? We have their marriage certificate & she signed legal documents stating she is my fathers spouse. How should I proceed?
