A formal notice is a written statement that triggers a legal process — starting a clock, creating a record, or putting the other side on notice of your position. Getting it right is important because courts and tribunals look at notices carefully.

What every notice needs

At minimum: the date, the full names and addresses of both parties, a clear statement of the matter (what you are claiming or requiring), the legal basis if you know it, a deadline for response where relevant, and your contact details. Keep the language plain. Courts distrust verbose notices full of legal jargon.

How to prove it was received

Send by first-class post and keep proof of posting (the Post Office receipt). For important notices, send by signed-for delivery — this gives you a tracking number and a delivery record. If you also send by email, note in both versions that you are sending by both methods. Never rely on email alone for a notice that starts a legal clock.

What to leave out

Do not include threats, insults, or unsupported claims. Do not write "without prejudice" on a formal notice unless you have taken legal advice on what that means — it can prevent the notice being used as evidence. Do not make demands you cannot legally enforce.
