A power of attorney is a document executed in writing and certified by a lawyer. One person(The principal) transfers to another person the right to represent their interests to third parties.
Types of powers of attorney in the USA:
· General — the interests of the principal can be represented in absolutely any sphere.
· Special — actions in the interests of the principal are performed in strictly limited areas.
· One-time — issued to perform one particular action in the interests of the principal.
In the United States, some powers of attorney can be valid indefinitely (this applies to internal authorities of attorney valid within the United States). Suppose a power of attorney is signed by an American lawyer but is intended for another country. In that case, its validity is usually limited to 1 year by default or a maximum of 3 years.
If its validity period is not specified, it is valid by default for only one year from the date of its signing.
