Probate and Estate Law

What is the name of your state (only U.S. law)? Az

My husband of 30 years comitted suicide on January 31, 2010, his father passed away on April 9, 2010, and he had a revocable trust which left his three children as beneficiaries including my husband, I was told by the trustee (his Uncle) that as a widow there is no provision for me so the funds my husband would get go to my son, if there is no provision for me then there is no provision for grandchild, can I fight this in probate court, am I not considered the next of kin as I am technically still his wife?

It all depends on the language of the trust document, as to what happens if one of the three children predeceases.

Ask for a copy of the trust document, on behalf of your son, and have a lawyer review.
