Nullity and the validity, O state or quality of what is null. The meaning of the term is used in the general scope to classify people or in the legal scope to invalidate any contract.

Nullity is a term used in law to specify that in the legal business there is some groundlessness or irregularity that requires the invalidity (nullity) of the contract. A legal transaction can have absolute or relative nullity. Absolute nullity consists of transactions where ratification is not allowed, for example, when its purpose was to defraud the law. Relative nullity (or voidability) designates a legal transaction that can be annulled, for example, when performed by relatively incapable individuals. In these cases, the ratification of the deal by the interested parties is allowed.
The nullity of a religious marriage designates the dissolution of the marriage, among other causes, when it happened not by its own will but due to imposition. When the evidence presented is sufficient, the ecclesiastical court declares a marriage null and void.
