My father passed away in New Jersey 5 months ago. I was named in the will along with my brother, sister and nephew. My brother is the executor of the will, but I have not spoken to him in 20 years. All beneficiaries of the will have received their inheritance except for me. I did receive a copy of the will, but all other emails to my brother have gone unanswered. When is it appropriate to take legal action, and where would I begin?
