Can a family member tranfer real estate to a family member without some form of compensation because she was the exsecutor of the will.

Your question makes no sense, but there is an issue here.  A transfer by an executor never has compensation if property is devised in a will.  A transfer by someone who does not own property is irrelevant -- like me transferring the Brooklyn Bridge.  A transfer by an executor to someone not in the will is voidable, and the executor is liable.
