They Couldn't Remember Exactly How It Happened, but the Mauri's

They couldn't remember exactly how it happened, but the Mauri's ended up a three-computer family with the consequent mess of books and papers in three different rooms. Mr. Mauri hired a general contractor, Mr. Wip, to build a "computer room." Wip had several qualified workers but still sub-contracted with an electrician and a carpenter. The work went well. Mauri held back 10%, but paid out 90% in good faith; i.e., when he paid, there were no complaints or liens filed. It turned out, however, that before anyone had completed his work--and no one expected payment until the job was finished-- Wip disappeared with the money. On these facts, which of the following is true?

A) The subcontractors, but not the workers, are entitled to place a lien on Mauri's property.
B) If the electrician failed to file his lien on time, he can file it late if he uses the right form.
C) If all those entitled to file a lien do file and prove in court the amounts owed, Mauri is responsible for the sum total of those claims.
D) The workers and subcontractors have an action against Wip for breach of contract.
E) If the carpenter properly files a lien in the appropriate office, he can be assured that he will recover the entire amount owed.
