My grandfather has passed away and my mother-in-law and I are guarantors to the financial estate; I need to know what I need to do?

If your grandfather passed away without a will it is called "intestate" and there are a set of laws that dictates who will recieve a share of his assets.  If he died with a will it is called "testate".  The will then dictates who will recieve a share of his assets, subject to certain exceptions.  Your statement that you and your mother are "guarantors to the financial estate" is confusing.  If you or your mother have guaranteed any of your grandfather's estate assets, it does not automatically mean that you are entitled to them, however, you may have a claim against the estate.  In any event, you should contact me so we may discuss the details of your question.  I think I can help you.  John R.
