What a lawyer's email signature has to carry
Legal practice is one of the few professions where the signature is partly a regulatory instrument. What it must contain is not a matter of taste, and the privilege line does less than people assume.

Regulated particulars
Most jurisdictions require a law firm to identify itself on correspondence: the firm's registered name and legal form, its regulator and often a registration or authorisation number, and the registered office. In some systems a partnership must also make available a list of partners, and the signature carries the statement of where that list can be inspected.
These requirements come from the professional regulator rather than from general company law, and they differ between jurisdictions, so the list your firm needs is the one your regulator publishes. What is common to all of them is that the requirement is not optional and the wording is not yours to improvise.
The privilege line, honestly
"This message may be privileged and confidential" appears on nearly every lawyer's email. Privilege attaches to the nature of the communication and the relationship between the parties, not to an assertion in a footer. A message that is not privileged does not become privileged because it says so.
What the line does accomplish is signalling to an unintended recipient that the sender considers the material sensitive, which may support an application if privilege is later disputed. That is a real if modest function, and one sentence carries it as well as a paragraph.
Qualification and jurisdiction
Where a lawyer is admitted matters to a client and is not obvious from the firm's address. A lawyer admitted in one jurisdiction working in an office in another should say so, because the alternative is a client assuming the wrong thing about who can advise them on what.
In multi-jurisdictional firms this is standard, and it is usually a short line under the name.
What to leave out
Directory rankings and award logos. They are images, they add weight to every message, they are marketing in a document that is partly a regulatory disclosure, and in some jurisdictions there are rules about how professional achievements may be advertised.
A long list of practice areas. The client writing to you already knows why.
Structuring a long required block
Contact details first at 14 pixels, then the regulated particulars at 11 pixels in grey, then the privilege line last. The reader needs the first, the regulator requires the second, and the third serves a purpose that does not depend on being read.
Because all of it repeats on every message in a thread, keep the whole block text-only. A regulated footer with no images can be under 500 bytes even when it carries four required particulars.
Ask, do not copy
The exact requirements are set by your regulator and change. Copying another firm's footer imports their jurisdiction, their legal form and possibly their mistakes. Your firm's compliance function will have the correct list, and asking for it is a five-minute conversation.
Measuring what the required block costs
A regulated footer with four particulars plus a privilege line runs to about 600 to 900 characters as plain text — under 1 KB. Add a firm logo at 12 KB and an awards badge at 8 KB and the same signature is 21 KB.
On a negotiation running to forty messages that is 840 KB against Gmail's 102 KB truncation point. The correspondence where the privilege line matters most is exactly the correspondence the images make unreadable.
Two signatures, and which carries what
New messages: full block with the logo and every required particular. Replies: name, direct line, and the required particulars as text with no images. The regulatory content is present on every message, which is what the rule asks, and the thread stays under the limit.
Frequently asked questions
Does the privilege line make a message privileged?
No. Privilege attaches to the nature of the communication and the relationship. The line signals the sender's view, which may support an application if privilege is later disputed.
What particulars does a law firm have to show?
Typically the registered name and legal form, the regulator and any authorisation number, and the registered office. The exact list comes from your regulator and differs by jurisdiction.
Should a lawyer state where they are admitted?
Where the office and the admission are in different jurisdictions, yes. Otherwise a client will assume the wrong thing.
Are award logos a problem?
They add weight to every message and some jurisdictions have rules about advertising professional achievements. Check before adding.
