Stipulations are contractual provisions that impose a specific obligation on one of the parties to a contract. They can be used to modify an existing agreement or to create new ones. Stipulations can be either positive or negative. Positive stipulations require one party to perform some action, while negative stipulations require one party to refrain from performing certain actions. Examples of stipulations include payment terms, delivery dates, warranties, indemnity clauses, and confidentiality agreements. There are also different types of stipulations, such as implied, express, and unilateral. Implied stipulations are those that the parties have agreed to without expressly stating them. Express stipulations are those that are explicitly stated in the contract. Unilateral stipulations are those that are placed on one party in the contract without the consent of the other party.
