A business letter of intent can be used in a number of situations including a commitment to purchase something, usually a business. It is also referred to as s Memorandum of Agreement (MOA) or Memorandum of Understanding (MOU).
Another contract law attorney, Ivan Hoffman of California, makes essentially the same point: "Parties to a transaction sometimes intentionally create a letter of intent as an expression of what they intend to agree upon should certain circumstances arise... [whatever happens], the document will not be binding and thus not enforceable until those circumstances arise. Thus, the letter of intent is essentially a legally worthless document. It is not clear to me the reason any party would ever bother to create such a document and yet I have seen it used on many occasions. If parties to a transaction intend to bind each other, then they should create a binding contract, not a letter of intent. If the parties to a transaction do not intend to bind each other, then why bother creating a document that is not binding?
