Frequently Asked Questions about Sample Letter for Agent Representation

Does this letter need to be notarised?

Notarisation is only required for legal, property or high value financial matters. For most everyday uses, a signed and dated letter is fully acceptable. Always check with the receiving organisation first.

How long is an agent representation letter valid?

Validity depends entirely on what you state in the document. Most letters use 30, 90 or 365 day periods. Never leave the end date blank, as this creates unlimited open authority.

Can I revoke this letter at any time?

Yes, you can cancel agent authority at any time for any reason. You must send written notice of revocation to both the agent and all third parties that received the original letter.

What is the difference between this letter and power of attorney?

This representation letter grants limited, task specific authority. Power of attorney grants much broader legal powers. Use this letter for single tasks or short term arrangements only.

Can an agent delegate their authority to someone else?

Agents cannot pass on their authority unless you explicitly permit this in the original letter. Most standard representation letters do not allow sub-delegation unless stated.

Do I need to send a physical copy or is email acceptable?

Most organisations now accept emailed signed copies. For formal or legal matters, send both an email and a physical registered mail copy for official records.

What happens if I do not issue this letter?

Third parties will refuse to work with your agent, you will experience unnecessary delays, and you will have no proof if the agent acts outside your instructions.

Can I use the same letter for multiple agents?

You should issue a separate unique letter for each individual agent. This removes confusion and lets you set different authority limits for each person.

What mistakes should I avoid when writing this letter?

Always avoid vague language, missing end dates, and undefined authority limits. Never grant more permission than is absolutely required for the task at hand.
