Is it absolutely necessary for the seller to be physically present at the registry office when registering a land sale in India? If so, what specific role do they play in the process?

No, the seller’s physical presence is not mandatory at the registry office during land sale registration in India. They can authorize a representative with a power of attorney to complete the process on their behalf. The seller’s primary role is to sign the sale deed and other relevant documents, confirming their consent to the transfer of ownership.
