Respected sir ...

The holder must have to sign the same in front of high commission ...nw here it will not work for you because for a valid POA both are requiere in front of attestation authority ...

Thank you

1.  POA  "MUST" be stamped for 500/- in India (after attestation) and no need to notarize or whatever in India, PROVIDED the same is duly attested by the Embassy /Consulate.  This is legally sufficient for all immovable properties in India.

Since POA is missing holder signature/acceptance, it`s incomplete. Get his signature on it and re registered in India at sub registrar office to avoid any manipulation in future.

1. The POA executed before the Indian Consulate should bear the signature of the POA holder also.

2. Thereafter the said POA shall have to be sent to the POA holder by post/courier service at his address.

3. Thereafter tyhe said  POA shall have to be adjudicated by the local Collector in India by affixing his seal and before affixing his seal, the office of the Controller might ask the envelope through which the overseas POA has been sent to the holder to be presented before the Collector to draw his satisfaction about the genuineness of the matter.

4. Thereafter the said POA becomes a valid instrument to deal with the concerned property.

You have to get the POA registered in Mumbai for execution of release deed and it is compulsory to register the POA.
