Notice is the mechanism by which a proceeding reaches a person, and it fails in predictable ways. What the notice must contain, who may deliver it, whether personal delivery is required, when mail suffices, what substituted service and publication require, and how service abroad works are all governed by rules that a defective attempt does not satisfy. This subject covers giving notice properly and proving afterwards that it was given.
Formal compliance and actual communication are separate things. A notice that satisfies every requirement can still fail to reach anybody who understands it, because the address is stale, the format is impenetrable, the channel is unmonitored or the recipient cannot read the language. Systems accept a degree of this, and the practical response is to comply formally and then communicate separately.
Proof of service is built at the moment of service and consulted long afterwards. The elements are a contemporaneous record of what was sent, to whom, when, by what method and by whom, supported by receipts, delivery confirmations and a formal certificate where the rules require one. Reconstructed evidence is markedly weaker and frequently decisive against the party relying on it.
Rules and contracts that require notice usually specify what the notice must contain, and a document missing a required element can be ineffective even where it plainly reached its recipient. The elements are commonly the identity of the parties, the nature of the matter, the action required, the period for responding and the consequence of not responding.
Personal service means delivering a document to the recipient directly, and most systems restrict who may perform it, exclude parties from doing it themselves, and require a sworn record of what happened. The method is the most robust available when done correctly and among the easiest to challenge when the server was ineligible or the record is thin.
Where the prescribed methods of service cannot be effected, most systems permit an application for an order allowing service by another means. The application turns on evidence that ordinary service was properly attempted and on a proposed alternative likely to bring the document to the recipient's attention, together with a date on which service is treated as effected.
Actual knowledge of a document and proper service of it are different things. Knowledge frequently helps where the requirement is procedural and the question is prejudice, and helps very little where the requirement conditions the forum's authority or where a statute prescribes a method strictly. Relying on knowledge is a defense to a defect rather than an alternative to complying.
Service by mail is permitted for many documents and excluded for some, and where it is permitted the rules usually specify the class of postage, the address that may be used, and the record that must be kept. Getting the method right is only part of it, because posting also changes when service is treated as effected and therefore when the recipient's time begins.
Service by email or through a filing portal is permitted widely, usually subject to consent or to a nominated address, and it takes effect at a moment the rules define rather than when the message is read. The recurring problems are consent that was never given, an address that was never nominated, and a timestamp recorded in a time zone nobody checked.
Service by publication permits a matter to proceed against somebody who cannot be located, by advertising the document in a prescribed manner. It requires an order, it requires evidence that every other avenue was exhausted, and the relief obtainable afterwards is frequently limited, because everybody understands that the recipient probably never saw it.
Serving a document outside the jurisdiction usually means using a treaty channel, a diplomatic route, or a method permitted by the law of the destination state. Each is slower than domestic service, each has formal requirements including translation, and service periods frequently need extending. The route is chosen by the destination, not by convenience.
Destination states declare which methods of service they accept, and several object to direct postal service, to service by private agents, or to both. A method used contrary to a declaration is generally invalid, the defect surfaces late, and the practical response is to read the declaration before choosing a route rather than afterwards.
Defects in service range from the trivial to the fatal. Some are cured by re-service, some are waived by a recipient who participates without objecting, and some cannot be cured at all because a period has expired. The first step is identifying which category applies, and the second is acting within whatever time remains rather than arguing about it.
