Which law governs the responsibilities of parties in an agreement?

Contract Law governs the responsibilities of parties in an agreement because it specifically focuses on the creation, enforcement, and interpretation of contracts. This area of law stipulates the obligations that individuals or entities enter into when they agree to certain terms, including the rights and duties that arise from those contractual agreements.

Contract Law outlines the necessary elements for a contract to be binding, such as offer, acceptance, consideration, and the mutual intention to create legal relations. It also provides remedies in case of breach, allowing parties to seek compensation or enforce the terms of the agreement.

In contrast, Tort Law deals with civil wrongs that cause harm or loss to individuals, usually outside of contractual obligations, such as negligence or defamation. Civil Law is a broader category that encompasses areas like contract law and tort law as part of private law, but it does not specifically address the duties and rights within contracts. Constitutional Law focuses on the structure and interpretation of government power and individual rights under a constitution, rather than the specifics of private agreements between parties.
