How can I legally challange my 88 years old Dad's Will.? He lives in Trinidad West Indies and is ill right now. Has five children and is leaving his entire estate for my Sister's daughter, his only granddaughter.
If he lives in Trinidad, you will need to contact an attorney there as will law is usually governed by the law of the residence of the person who writes the will. There is one exception. Real estate owned by a decedent is always probated in the jurisdiction where the real estate is located. So if your father's will includes Nevada real estate there will ultimately be a Nevada probate. In any event, since your father is still alive, it is too early to challenge his will.
