This is not a criminal matter but I urge you to retain a probate attorney in Oregon to find out what is happening with the estate and possibly file a motion to remove the executor if he is not fulfilling his duties to the estate.
Please note that I am answering this question as a service through Avvo but not as your attorney and no attorney-client relationship is established by this posting. An attorney-client relationship can only be established through signing a Fee Agreement and paying the necessary advanced fees.
While you can call the Probate court and request copies of all filed documents (for a fee of course) this will only tell you part of the story.
Seek legal counsel to represent you and find out all relevant facts to help you determine what courses of action there are and what you want to do.
