My Mother named me as Heir Beneficiary of Life Ins. Family member stole and forged and collected benefits

After my father Passed It was proven he had stolen the policy I received .a call from attorney who I had told what happened He researched and found the story and sworn witnesses He said 275,000 for starters before I could get to his office . to sign and cash check My Trustee moved my Fathers Trust into the same office now no one seems to know where the check is.I have so many issues after being lied to and tricked by my own Dad now my Trustee and the Lawyer who found it for me seems to be holding something back since his partner handles my Dads Estate
