My husbands buisness is being sued and im just wondering how its possible. we were owed money by a buiness that went bankrupt. they came back into buisness and where told they had to pay there depts. so we filled out all the paper work to include invoices. now we are getting sued from this other lawyer saying we got preferental treatment because we got paid for other jobs we did for the company when they were filing bankrupsy? how is this possible? we did the work. the papers keep coming in the mail. we dont have to sign for them just regular mail. should i be worried? if so what should we do?
