You should execute POA in favour of close family member like your parents or siblings 

2) if you execute POA in favour of father in law it would attract higher stamp duty and has to be stamped as conveyance 

3) POA should be attested before Indian consulate 

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.(Foreign Power of Attorney should be stamped by the Collector after its receipt in India within prescribed time of 3 months)

Another step

The POA executed in a foreign country and duly attested by the Indian consulate in 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.  If the registrar is not following the rules, the matter may be taken up with the Dy.director, Registration for solution.

1. If you are going to give POA to a non-blood relative (father-in-law) to sell your property in India, then the stamp duty would be around 5% of the value of the property. However, if you are going to give POA to a blood-relative, say father, mother, brother or sister, the stamp duty would be minimal.

2.  The procedure is given below:-

Get the POA prepared, signed by you after pasting the photo of the principal and obtain signature of the Indian Consulate Officer or countersigned by a Notary and send it to the Agent/Attorney (anyone to be appointed by you) in India, who will paste his photo and sign the document.
