Guillermo and Guadalupe Albarran and their sons, Ruben and Rolando, owned R. Cleaning Impact, Inc. (RCI). Neresh Kumar owned Amba II, Inc., a check-cashing business. The Albarrans cashed checks through Amba on a regular basis, often delivering a stack of employee paychecks to Amba for cashing. Later, the Albarrans’ bank refused payment on some of the checks. Kumar learned that some of these items were payable to fictitious payees with fictitious addresses. Others had been filled out for amounts greater than real employees’ pay. Meanwhile, RCI became insolvent and closed its account, and Guillermo and Guadalupe filed for bankruptcy. Amba was left with many unpaid checks. Among these parties, who can be held liable for the loss on the unpaid checks? Explain. [Albarran v. Amba II, Inc., 2016 WL 688924 (2016)] (See Signature Liability.)
