English to Croatian Law/Patents Other

Dragi svi,

muci me sljedeca recenica:

An instrument of proxy, and (if required) a power of attorney or other authority under which it is executed or a copy of it notarially certified or certified in some other way approved by the Board, shall be deposited ...

Nisam sigurna kako u ovoj recenici prevesti instrument of proxy,a kako power of attorney.

Hvala unaprijed.
Laura
