Requisites

Requisites are conditions or items that are required or necessary for something to occur or be valid. The term is often used interchangeably with prerequisites or requirements, though its usage can imply formal, essential conditions in administrative, legal, or organizational contexts.

In education, requisites refer to prerequisites—courses, exams, or qualifications that a student must complete before enrolling in a given course or program. Requisites establish a sequence of study and help ensure readiness. Institutions publish lists of core requisites and may grant waivers under certain circumstances.

In law and civil affairs, requisites denote essential elements or conditions required for a transaction or action to be legally valid. For example, many contracts are described as having requisite elements such as offer, acceptance, consideration, and capacity. Some statutes specify requisites for valid legal notices, incorporations, or filings.

In business and project management, requisites include funding, personnel, equipment, licenses, permits, and stakeholder approvals necessary to initiate or complete a project. In software and information technology, system or installation requisites refer to hardware and software requirements that a product must meet to function.

In logic and philosophy, a requisite can refer to a necessary condition: if the condition is not present, the outcome cannot occur, though its presence alone may not guarantee it. Understanding requisites helps clarify what is genuinely required versus what is merely helpful.
