4.7 Ratification is the process of formally agreeing to a document, contract, or amendment. It is a legal process and requires the agreement of all parties involved in order to be legally binding. There are two main types of 4.7 Ratification: express and implied. Express Ratification is when all parties involved sign a written document indicating their agreement. Implied Ratification is when the parties involved act in a manner that implies their agreement, even if they have not signed a document. In either case, 4.7 Ratification is a legally binding agreement that carries the same weight as any other legal contract.
