Which type of contract ensures that all terms are incorporated even if parties have not read them?

The type of contract that ensures all terms are incorporated, even if the parties have not read them, is indeed a written contract. Written contracts often include terms that are standardized or widely recognized within a specific context. They can contain clauses that outline the rights and responsibilities of each party. This is particularly relevant in situations where one party may not have fully reviewed all provisions, yet they are still legally bound by the terms once they have signed the document.

In written contracts, the incorporation of terms is based on the understanding that parties are presumed to have read and understood the contract before signing. Courts generally uphold this principle, meaning that even if a party did not read a clause, they are still bound by it, unless there is a specific reason to challenge the enforceability of that term, such as unconscionability or fraud.

Other types of contracts, such as implied contracts or unilateral contracts, do not have the same framework for incorporating unwritten terms. An implied contract arises from conduct or circumstances rather than explicit written or spoken terms, and a unilateral contract is based on one party making a promise in exchange for an act by another party. Neither of these provide the same legal binding effect as a written contract that includes terms known to the parties.
