n. 1) information, usually in writing in all legal proceedings, of all documents filed, decisions, requests, motions, petitions, and upcoming dates. Notice is a vital principle of fairness and due process in legal procedure and must be given to both parties, to all those affected by a lawsuit or legal proceeding, to the opposing attorney and to the court. In short, neither a party nor the court can operate in secret, make private overtures or conceal actions. Notice of a lawsuit or petition for a court order begins with personal service on the defendants (delivery of notice to the person) of the complaint or petition, together with a summons or order to appear (or file an answer) in court. Thereafter, if a party is represented by an attorney, notice can usually be given to the attorney by mail. If there is a so-called ex parte hearing (an emergency session with a judge with only the requesting party or his/her attorney present) the party wanting the hearing must make a diligent attempt to give notice to the other party. A court may allow "constructive" notice by publication in an approved legal newspaper of a summons in a lawsuit. Examples: in a divorce action, publication gives constructive notice to a spouse known to have left the state or hiding to avoid service; in a quiet title action, notice by publication is given to alert unknown descendants of a dead person who may have had an interest in the real property which is the subject of a lawsuit. Recordation of deeds, mortgages, deeds of trust, easements, leases and other documents affecting real property title give "constructive" notice to the general public, and thus "constructive" notice to anyone interested in the property, without delivering notice to individuals. 2) a writing informing a party to a contract, promissory note, lease, rental agreement or other legal relationship of a delinquency in payment, default, intent to foreclose, notice to pay rent or quit (leave) or other notice required by the agreement, mortgage, deed of trust or statute. 3) information. 4) being informed of a fact, or should have known based on the circumstances, as "he had notice that the roof was not water-tight."
