Answer:
1. A.
2. a.
Step-by-step explanation:
1. In this scenario, the only legal argument that they can make would be that Sheila was unable to understand what she was signing when she signed the will. Even though the bar for mental incompetence when dealing with a Will is extremely low, they can still dispute the will under this claim. Mainly due to the fact that she was declared Mentally Incompetent by a court judge, thus giving the claim much more validity and possibility of being accepted by the court.
2. If the court accepts this claim then the entirety of Sheila's estate will be distributed evenly among her next of kin, which in this case would be her children. Therefore, the estate will be divided evenly, one third each to Elmo, Mark and Paula, who are all of Sheila's adult children.
