biological children's rights to deceased Dad's share of property
Hi; My children are both adults whose father is recently deceased. He remarried several years ago. He was diagnosed with a brain tumor (which he had removed via surgery). The stepmother advised that he had a will which left everything to her. She received a sizeable amount upon his death from a life insurance policy. She is now asking my children to sign a paper on two vehicles which were in the decedent's name only. Since my daughter was not informed as to the exact nature of this paper work she didn't sign them. Now the step mom is threatening to take my daughter to court and sue her for the cost of the succession as well as a portion of the funeral expenses. My questions are 1. Is there any ramifications to my daughter if she does sign these papers. 2. Does this will really have any validation to cause my children to lose any portion that should be theirs.. such as a portion of the value of the home? There is not really anything else of value. Also would this will be considered invalid since it was implemented after their Dad's diagnosis -(he lost all of his short term memory and might be considered to have diminished mental capacity.
Thanks
