The notices clause decides when you were told

A clause about envelopes that governs every deadline

Among the closing provisions of most agreements is a passage specifying how formal communications must be sent: to which address, by which methods, and when they are treated as having arrived. It looks like administrative housekeeping. It is the provision that fixes the start date for nearly every period the document mentions.

Every notice period, cure period, cancellation window and response deadline runs from a date, and this clause defines the date. A perfectly correct notice sent by a method the clause does not recognise may not count as given at all, and a notice sent correctly may count as given several days before anybody read it.

Deemed delivery is the part that surprises people

The characteristic feature is deeming language: a notice sent by a specified method is treated as received after a stated interval, whether or not it actually was. Two working days after posting, at the moment of transmission for an email, on delivery for a courier — the details vary and the structure does not.

The purpose is to make the date provable without an argument about what happened to a letter. It also means the deadline can begin running while the envelope is still in transit, and it means a notice sent to a valid address counts even if the recipient has moved, stopped checking that inbox, or filed it unopened. What is being deemed is delivery, not attention.

The address on the front page is not decorative

Notices clauses tie delivery to specific addresses, usually the ones stated at the beginning of the agreement, and usually with a mechanism for changing them by giving notice in the same manner. That mechanism is the part everybody forgets. Moving premises or changing a contact address without following it leaves the old address as the valid one for the purposes of the document.

The same applies to named roles. Clauses often require a copy to a particular position — a company secretary, a legal contact, a designated manager — and a notice sent to a person who has left, or to a general enquiries address, may be defective even though it plainly reached the organisation. The requirement isn’t about whether somebody saw it; it’s about whether the specified route was used.

Which methods are listed tells you something

The methods listed vary and the list is closed unless it says otherwise. Registered post appears almost universally because it produces independent evidence of dispatch and delivery. Email is increasingly included and often carries conditions — a specific address, a requirement to send a copy another way, or an exclusion for certain categories such as termination.

Where a method is excluded for the most serious notices, the reasoning is usually about evidence and about the gravity of the act. Terminating an arrangement by an email that may have been filtered is a poor arrangement for everyone. That is why some documents accept email for routine matters and demand paper for anything that ends the relationship.

Notices sent to you follow the same rules

The clause is reciprocal, which is the direction most readers overlook. Whatever methods are permitted for your notices are generally permitted for theirs, so the deeming provisions determine when you are treated as having been told about a change, a charge or a decision.

This is where the notices clause connects to the variation clause and to the section on charges. If terms can be changed on notice, and notice by publication or email is deemed received on a defined day, then the response window is set by the combination of those two provisions rather than by either alone. Reading them together takes two minutes and is the only way to see the actual timetable.

What to do with the clause in practice

When sending anything that matters, check the clause first, use a listed method, send to the stated address including any copy requirement, and keep proof of dispatch. When your contact details change, follow the mechanism the document specifies rather than updating an account profile and assuming it propagated.

And when something arrives, note the date it was sent as well as the date you opened it, since the first is the one the document cares about. As always, this describes how such clauses are constructed rather than advising on any particular one; if a deadline turns on the wording, that wording needs proper attention from somebody qualified to give it.
