An omission; a failure to do that which is anticipated, expected, or required in a given situation.
Default is distinguishable from NEGLIGENCE in that it does not involve carelessness or imprudence with respect to the discharge of a duty or obligation but rather the intentional omission or nonperformance of a duty.
To default on a debt is to fail to pay it upon its due date. Default in contract law implies failure to perform a contractual obligation.
A default judgment is one that may be entered against a party in a lawsuit for failure to comply with a procedural step in the suit, such as failure to file an answer to a complaint or failure to file a paper on time. A default judgment is not one that goes to the merits of a lawsuit but is procedural in nature.
