Choosing the right format

Define the task and recipient before selecting a format. A letter may not meet the requirements for a formal power of attorney or an institution’s own authorization process. Check acceptance rules for banking, property or other significant matters.

Details to include

  • Writer, authorized person and intended recipient
  • Specific action and relevant reference details
  • Effective dates, limits and writer’s signature

How to use the template

  1. Confirm the recipient’s required format and identification checks.
  2. State the authority narrowly and avoid unnecessary personal data.
  3. Sign as required and provide copies through the accepted process.

Worked example

A limited letter might authorize a named person to collect one specified document during a stated period. It should not grant unrelated transaction authority.

Download and printing notes
