When you need to sign a letter for another person, the wording beneath your signature matters more than you might think. A clear signature notation tells the recipient who authorized the letter, who actually signed it, and in what capacity the signer is acting. Whether you are an executive assistant signing for a manager, an employee representing a company director, or an authorized representative handling correspondence, the right phrase keeps the communication professional and transparent. There are several ways to indicate that you are signing on someone else’s behalf, and each expression carries a slightly different level of formality. Choosing the right wording can make business correspondence feel polished without sounding unnecessarily stiff. Below, you will find 30+ ways to sign a letter on behalf of someone else, with meanings, tones, examples, and practical guidance to help you choose the expression that fits your situation.
What Does “Sign a Letter on Behalf of Someone Else” Mean?
To sign a letter on behalf of someone else means to write or authorize your signature as a representative of another person who has given you permission to act for them.
For example, an executive assistant may sign a letter for a company director, or an authorized employee may sign correspondence for a department head.
Common notations include:
- For [Name]
- On behalf of [Name]
- For and on behalf of [Name]
- pp [Name]
- Per procurationem (p.p.)
- [Your Name], for [Name]
The tone is generally formal, professional, and transparent. The exact wording should make it clear that you are not pretending to be the person whose name appears on the correspondence.
When to Use It
You may need to sign on behalf of another person in many professional and administrative situations.
Business Correspondence
An assistant may sign a letter for a manager who is unavailable.
Example: “For Maria Thompson, Operations Director”
Corporate Letters
An authorized employee may sign correspondence representing a senior executive or company representative.
Example: “For and on behalf of the Managing Director”
Legal or Administrative Documents
Some documents require a clearly identified authorized representative. In these cases, follow the organization’s signing authority and any applicable legal requirements.
Email Correspondence
When sending an email for another person, you can make the representation clear in the closing.
Example: “Kind regards, James Lee, on behalf of Sarah Williams.”
Client Communications
An assistant or team member can communicate with clients on behalf of an executive while maintaining transparency about who actually sent the message.
Letters Written by an Assistant
An assistant may prepare and sign routine correspondence when authorized to do so.
Example: “Yours sincerely, Alex Morgan, for David Chen.”
Formal Speeches or Announcements
The same principle can apply when delivering a written statement or announcement for another person.
Example: “Delivered on behalf of the Chairperson.”
Is It Polite or Professional?
Yes. Signing a letter on behalf of someone else can be completely professional when you have the appropriate authorization and clearly identify your representative capacity.
The most important consideration is transparency. The recipient should not be misled into believing that the named person personally signed the document when someone else actually did.
For highly formal correspondence, expressions such as “For and on behalf of” or “p.p.” may be appropriate. For everyday business communication, “On behalf of” or “For [Name]” is often clearer and more accessible.
The appropriate expression can also depend on company policy, signing authority, jurisdiction, and the type of document. For contracts, legal documents, financial instruments, or official filings, use the organization’s prescribed signing procedure rather than relying solely on a general signature phrase.
