In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
If your asking if you are entitled to a share of the construction business or its assets after your father's passing, then a probate attorney would most likely be correct. If your father passed leaving any kind of a will or trust, drafted by an attorney, that attorney could be a good source of contact for you.
