Regulatory and legal notices

What a formal notice is

Last checked 6 November 2026 · 10 sources

Short answer

A formal notice is a document a law or rule requires one party to give another, in a set form and by a set time. Some go to a regulator, such as a UK GDPR breach notice due where feasible within 72 hours ¹. Some go to the market, such as an SEC Form 8-K Item 1.05 filing ². Some come from a regulator, such as an FCA warning notice, which the FCA says is not its final decision ⁵. Each type has its own legal effect.

Breach notice to a regulator: UK GDPR: without undue delay and where feasible within 72 hours ¹
Securities disclosure: SEC Form 8-K Item 1.05, four business days after a materiality decision ²
Recall notice: Australia: tell the ACCC within 2 days ³
Layoff notice: US WARN Act: 60 days ⁴
Regulatory notice: FCA warning notice is not a final decision ⁵
Court notice: US summons served with the complaint within 90 days of filing ⁹

Four questions that define any notice

This site describes each notice by four points: who must give it, who must receive it, the deadline, and the form it takes. Rules set all four.

The UK GDPR gives a clear example. The controller gives the notice, the regulator receives it, the deadline is without undue delay and where feasible within 72 hours, and a late notice must give reasons ¹. A processor gives a separate notice to the controller ¹.

The US WARN Act is another. A covered employer may not order a plant closing or mass layoff until 60 days after written notice ⁴.

Notices given by companies

Many notices are duties placed on a business. A listed US company must file Form 8-K Item 1.05 about a material cybersecurity incident, as a general rule four business days after deciding it is material ². An Australian supplier that recalls a consumer product for safety reasons must tell the ACCC within 2 days, under section 128 of the Australian Consumer Law ³. Failure to give these notices can carry penalties. Under the WARN Act, an employer is liable for back pay for each day of violation, up to 60 days ⁴.

Notices given by regulators

Regulators issue notices that mark stages in a process. The difference between stages matters.

At the UK FCA, a warning notice sets out proposed action and is not the final decision ⁵. A decision notice follows if the FCA decides to act, and it can be referred to the Upper Tribunal ⁶. A final notice is issued when the FCA takes action ⁵.

At the US FDA, a Form 483 lists observations at the end of an inspection and is not a final agency determination ⁸. A warning letter is informal and advisory and does not commit the FDA to enforcement action ⁷.

Notice	Issuer	Final?
Warning notice	UK FCA ⁵	No ⁵
Decision notice	UK FCA ⁶	Open to referral to the Upper Tribunal ⁶
Final notice	UK FCA ⁶	Issued when no referral is made in time ⁶
Form FDA 483	US FDA ⁸	No, not a final agency determination ⁸
Warning letter	US FDA ⁷	No, informal and advisory ⁷

Court notices and service

Court notices depend on service, the formal delivery of papers. In US federal courts, a summons must be served with a copy of the complaint ⁹. In England and Wales, Civil Procedure Rules Part 6 sets the methods and a claim form is deemed served on the second business day after the relevant step ¹⁰.

Common mix-ups

A warning notice is not a penalty. The FCA says it is not its final decision ⁵.
A decision notice is not always the end. It can be referred to the Upper Tribunal, normally within 28 days ⁶.
An FDA warning letter is not a recall or a court order. The FDA calls it informal and advisory ⁷.
A notice to a regulator is not the same as a notice to the public. UK GDPR Article 33 covers the regulator only ¹.

Common questions

Is a warning notice the same as a fine?

No. At the FCA, a warning notice sets out proposed action and is not the final decision ⁵.

What is the difference between a decision notice and a final notice?

A decision notice can be referred to the Upper Tribunal. A final notice is issued if no referral is made in time ⁶.

Is an FDA warning letter legally binding?

The FDA calls it informal and advisory, and it does not commit the agency to enforcement action ⁷.

What does deemed service mean?

The date the rules treat papers as delivered. In England and Wales, a claim form is deemed served on the second business day after the relevant step ¹⁰.
