Is an authorization letter the same as a power of attorney?

No. This covers one named task and carries no legal authority over your affairs. A power of attorney is a formal instrument, usually witnessed or notarised, and is what you need for anything financial or medical.

Does it need to be notarised?

For collecting documents, usually not. Banks, land registries and government offices often do require notarisation, so check before you send someone across a city.

What should the person bring with them?

This letter, their own identification, and often a copy of yours. Say in the letter which identification they will carry so the office knows what to expect.

Should I put an expiry date on it?

Yes. An authorization with no end date stays valid indefinitely and is awkward to withdraw. Give it a window that covers the task and no more.

Can one letter authorise several things?

It can, but each one has to be written out. Anything not named in the letter is not authorised, which is the point of writing it down.

Authorization letter

You need someone else to collect something or act for you.

An authorization letter lets a named person do one specific thing on your behalf: collect a document, sign for a delivery, deal with an office you cannot get to. It is not a power of attorney and does not replace one.

Name the person, name the task, and put an end date on it. An open-ended authorization is one you cannot easily withdraw.
