Certainty Law and Legal Definition

Certainty is a state of being free of any doubt. Certainty means assurance or the state of being certain, such as the certainty of death. In Contract law, the terms of a contract are certain when each of the provision is described or explained properly and clearly set forth.

The maxims “terminius annorum certus debet esse et determinatus” means that “a term of years ought to be certain and determinate” and “certum est quod certum reddi potest” means “that is certain which is capable of being rendered certain.”
