Another recent decision of the Supreme Court addresses two key points. The first is the need to have agreed contract terms, before work starts under a contract and the second that, where a letter of intent is signed and work starts due to it, that a contract must be finalized as soon as possible after that. In this case, the parties entered into a contract formed by a letter of intent. When the letter of intent expired the work continued on, before the terms of the detailed written contract had been finalized.
LOI is used as manipulation tool at the hands of unscrupulous sellers & agents. Often times, obscure or scam_oriented persons who claim to be crude Sellers, or represent themselves as sellers' agents, mandates or brokers largely by an Internet contact or communication, employ the LOI merely as a tool to quickly "corner and box in" a prospective buyer to a purchase deal, before the prospective buyer may demand that they provide their business profile or show him something tangible to demonstrate that they are truly legitimate sellers.
