You have far more questions in your summary than you have information about what has taken place. You have a very complex and unusual situation and there is no way anyone on Avvo can help you without being able to sift through ALL the facts of your situation. You need to consult with a probate lawyer as soon as possible, so you can get some answers. This forum is not set up to deal with circumstances like yours.

These responses should be considered general legal education and are intended to provide general information about the question asked.

If I refer to your state's laws, you should not rely on what I say; I just did a quick Internet search and found something that looked relevant that I hoped you would find helpful. You should verify and confirm any information provided with an attorney licensed in your state.
James is right you need to see a lawyer about all these many questions which are dependent on lots of facts too numerous to mention.
One thing I do want to say however is that in some states lawyers get can temporarily suspended for not getting enough CLEs (continuing education credits) or forgetting to pay dues; but not all of these are necessarily bad lawyers. In fact I have seen many good lawyers get temporarily suspended for missing a CLE minimum cutoff date. Bottom line you need a lawyer to correctly interpret all the complicated issues you have mentioned.

You have brought up a variety of issues in a relatively short question. If you can establish that the executor of the estate has breached his or her fiduciary duties, you should be able to have the executor replaced. Whether or not you are the best replacement is going to require more information. If the attorney's license has been suspended, he cannot practice.
You should contact a probate attorney in the county where the probate is filed to explore your information in greater detail.
