What type property does she want the receiver to take? Receivers are expensive and usually a last resort. That being said, I'd look for a board certified family lawyer or a board certified civil trial specialist. Either should be able to handle the motion for appointment of a receiver. Don't wait too long.
I am not intending this to be legal advice, because I don't know the particulars of your situation. Call me if you would like to discuss this or other isues.
