Final answer:
The authorized representative or POA must sign the application to validate it. Their signature serves to confirm their authority to act on behalf of someone or an organization.
Step-by-step explanation:
The authorized representative or Power of Attorney (POA) must sign the application to validate it. Their signature serves as proof that they have the authority to act on behalf of the individual or organization they represent.
For example, in legal documents such as contracts or agreements, the authorized representative or POA may sign next to a statement such as 'Executed by:' or 'Signed on behalf of:' followed by their name, title, and date.
It is important to ensure that the authorized representative or POA signs the application correctly and legibly to avoid any legal issues or disputes.
