Frequently Asked Questions about Sample Letter for Authorization

Does an authorization letter need to be notarized?

Most everyday authorization letters do not require notarization. Only use a notary for high value transactions, legal matters or if the receiving organization explicitly requests it.

How long is an authorization letter valid?

An authorization letter is valid for the exact time period written in the document. Always include a clear end date, never leave this open ended.

Can I send a digital copy of an authorization letter?

Many organizations accept clear digital copies, but always check first. Most official bodies will still require a handwritten signature on the document.

What should I never include in an authorization letter?

Never grant general unlimited permission. Never share sensitive login details, social security numbers or banking passwords in this letter.

Can anyone be named as an authorized person?

You may name any trusted adult as your authorized person. The recipient will only check that they can verify the person’s identity with official ID.

Can I cancel an authorization letter early?

Yes, you can cancel an authorization at any time. Notify the receiving organization in writing and request confirmation of cancellation.

Do I need to state a reason for the authorization?

You do not have to explain why you need help. You only need to clearly state what actions the other person is allowed to take.

Is an email authorization considered valid?

An email counts only if the receiving organization has confirmed they accept this format. Printed signed letters are always the safest standard option.

Can I use a handwritten authorization letter?

Handwritten letters are fully valid as long as they are legible and contain all required details. Typed letters are preferred for official use.

Every Sample Letter for Authorization works best when it is specific, clear and time limited.
