If a 'Power of Attorney' given to an Indian resident by a NRI from outside India is valid and acceptable by Indian.
STEP 1: Write the power of attorney on plain paper. There is no need to create it on stamp paper from India, subject to conditions. Sign the power of attorney. Two witnesses should also sign this document. The addresses of the applicant and witnesses should be typed clearly. All this must be done in the presence of a notary public. You can also get this done at the Indian Consulate as well.Once your power of attorney is attested by the Indian Consulate/Embassy you can send it to India. and adjudicate the same before collector or district registrar.

Another step :
The POA executed in a foreign country and duly attested by Indian consulate of that country, sent by a sealed cover to the concerned registrar directly to be opened by him in front of the POA agent will be the correct procedure to be followed. The principle need not come to registrar's office physically for registering the same.
