Go ask that attorney if in fact he's done anything, and if he considers himself attorney of record for your case. Get a complete understanding of what he proposes and what his remuneration is. Have you signed any sort of letter of intent for him to represent you on matters arising from your father's death and his estate and class action law-suit?
You need to be more assertive. You need to make an appointment with the attorney handling the case, particularly if you have no attorney representing you personally.
