It sounds like there may have been notice issues. As an heir, you should have been served notice of the probate of his estate. If that is not the case, then you need to immediately retain an attorney to intervene in the probate case. I recommend finding an attorney in or near the county where the probate case is open as each County has their own rules and procedures.
Best of luck.
