Is it legal for receiver of heirs' property to sell same without approval from heirs. Property has contract on it and receiver, also a family member, refuses to discuss with family. Would an injunction stop sale until family meets?

I can understand that this is a frustrating situation. I would suggest that you post this under estate planning as well. I would also suggest that you speak with an attorney immediately to discuss your options. You can locate one through the attorney locator on Lawinfo's home page at http://www.lawinfo.com/. Some do offer free consultations.
