Registration is the process of presentation of the deed/document physically

 in the office of the Sub-Registrar by the party(ies) to the deed. Various

 documents and deeds need to be registered as per the law; these documents

 are generally referred as 'Instruments'

The registration of an instrument is carried out in pursuance of the rules

 specified in this behalf and the main idea is to make the documents 

relating to immovable properties public. It also provides sanctity to the

 document and proves the genuiness of parties to certain extent as they

 personally appear before the registrar. Once the Stamp Duty has been paid,

 the instrument is registered by Sub-Registrar after verifying the other 

details.
