Happened to me beginning in 2018, my sister and her evil, controlling husband sued me as executor of my Mother’s Trust, myself as an individual, and my Mother to Court who was in good health at the time beginning in 2014 which drug out for near 4 years and as the trial neared they recruited my oldest Son to testify against me and my Mother as he has a whole lot of anger issues due to my Ex-Wife lies. Anyway he got up there and lied about everything, how I mistreated him, his Grandma mistreated him, just BS lies... After that little incident he refuses to allow me to see the Grandkids or no interest in seeing his dying Grandma so I have prayed and prayed and God gave me the answer to let him go as he would deal with him and move on, so I have. Needless to say his life is pretty crappy these days..Good enough for him.
So many kids are suing the Parents for their inheritance any more, want it right now even if the parents still alive and well. During my time in the Court system I saw a dozen hearings where the kids demanded what the Parents had.
