But Notarising a power of attorney is as good as registration . Section 85 of the Indian Evidence Act applies to the documents authenticated by a notary. A court will presume that every document purporting to be a power of attorney, that has been executed before and authenticated by a notary public or any court, is properly executed and is a conclusive proof. Each page of a document notarised should bear the official stamp of the notary disclosing his registration number and jurisdiction , and also his signature. Appropriate notary stamp has to be affixed.
