- Keep a copy of the signed letter for your records.
- Notify the relevant institution as soon as the authorization ends.

Depending on the purpose, you may need to provide the letter to:
- Bank branches or corporate finance offices.

- Legal firms or courts.
- Realestate agencies or title companies.
- Employers when delegating signing authority for HR documents.
