You can certainly execute the Power of Attorney at the Indian Embassy with the attastation of the Consulate of India. Remember few things before you draft or execute the Power of Attorney.
1. Mention the descripttion of the property in detail. You can get that information from your existing Sale deed or Mother document. You can copy paste the same details.
2. Mention the Power of Attorney is for SIGNING AND EXECUTION of every property related document including Sale Deed, Agreements, Correction Deed and for the applications at the records of the Revenue Department.
3. Get two witnesses to sign the Power of Attorney while signing and execution of the Power of Attorney at the Indian Embassy.
It's a simple procedure.
Remember, If you have the property located in Pune, then you / the power of attorney holder has to execute your Sale Deed or Agreement at Pune only i.e. at the office of the Sub-registrar of Pune only.
I hope this information is helpful to you.
