How Should Letters, Emails, Contracts, etc, from My Company be Signed?

by Peter Cusimano
Lawyer - Barrister & Solicitor

It is important that all documents that originate from your company be properly signed. Often times people do not pay attention to this minor detail which can have severe consequences.

The proper way to sign all documents that originate from your company is to include the full legal name of the corporation and then sign on behalf of the company.

For example, if your company's name is ABC Computer Inc., and you are Joe Smith, President, then the proper way to sign all documents is as follows:

per: John Smith
The above format signifies that the document is from the corporation and not the individual.
In addition, "per:" refers to "on behalf of". Essentially, John Smith is signing on behalf of the corporation, and not in an individual capacity. The title "President" signifies the title or authority of the person signing the document in their capacity as an authorized signing officer of the company.

You should use the above format for all documents where a signature is required including:
  • letters
  • emails
  • invoices
  • cheques
  • contracts / agreements
  • price quotes / estimates / purchase orders
