This is not a general question you ask. You are clearly in need of a legal advice. No problem, but not on AVVO. AVVO is a free general legal information blog, not a substitute for legal advice. Look for at attorney you would like to have a consultation with. You can use Find a Lawyer tab above, right here in AVVO. Select an attorney, contact them directly and schedule a consultation.
