The term that describes a duty that is enforced by a court and where non-fulfilment may incur a penalty.

Any matter of fact that a party to a claim or action offers to provide to prove or disprove an issue in the case. The strongest type of evidence is that which provides direct proof of the truth of an assertion. At the other extreme is evidence that is merely consistent with an assertion but does not rule out other, contradictory assertions, and may be viewed as circumstantial evidence.

A period immediately after the deadline for the performance of an obligation during which a late fee or penalty, or other action would have been taken as a result of failing to meet the deadline, is waived provided that the obligation is satisfied during the grace period. Grace periods can range from a couple of minutes to a number of days or longer, depending on the context, and can apply in various situations, such as complying with a legal obligation by a specified deadline.
