Invalidity

Sometimes a legal act is voidable. This means that a legal act can be declared invalid by a party. For example, a legal act is null and void if it is the result of a threat, deception or abuse of circumstances.

A void legal act is legally valid, as long as invalidity has not been invoked. This is different for a legal act that is null and void. By invoking the voidability of the legal act, no legal act has ever taken place retroactively.
