A standard form contract (sometimes referred to as a contract of adhesion, a leonine contract, a take-it-or-leave-it contract, or a boilerplate contract) is a contract between two parties, where the terms and conditions of the contract are set by one of the parties, and the other party has little or no ability to negotiate more favorable terms and is thus placed in a "take it or leave it" position.

While these types of contracts are not illegal per se, there exists a potential for unconscionability. In addition, in the event of an ambiguity, such ambiguity will be resolved contra proferentem, for example, against the party drafting the contract language.

In contract law, an integration clause, merger clause, (sometimes, particularly in the United Kingdom, referred to as an entire agreement clause) is a clause in a written contract which declares that contract to be the complete and final agreement between the parties. It is often placed at or towards the end of the contract. Any pre-contractual material which the parties wish to be incorporated into the contract needs

Contra proferentem (Latin: "against the offeror"), also known as "interpretation against the draftsman", is a doctrine of contractual interpretation providing that, where a promise, agreement or term is ambiguous, the preferred meaning should be the one that works against the interests of the party who provided the wording. The doctrine is often applied to situations involving standardized contracts or where the parties are of unequal bargaining power, but is applicable to other cases. The doctrine is not, however, directly applicable to situations where the language at issue is mandated by law, as is often the case with insurance contracts and bills of lading.
