Notarisation and registration serve entirely different purposes in law, and clients often confuse the two. Registration is a formal recording of the instrument before the Sub-Registrar, which gives the instrument public notice and, for transfers of immovable property, is what actually passes title from one person to another in law. The notary acts as a witness of identity, while the registrar acts as the public custodian of the title record of the state.
Notarisation, by contrast, authenticates signatures and certifies copies and affidavits. It does not transfer title and it does not replace a registered deed, for a notarised sale agreement may be strong evidence of a transaction, but it is not a substitute for a registered sale deed before the courts. It is therefore a supporting act and not a substitute for the formal registration that the law requires for a transfer.
For this reason property deeds in West Bengal are registered even when they are also witnessed and notarised, while supporting documents such as affidavits, declarations and indemnity bonds are commonly only notarised. Clients in Asansol should know which route their particular document actually requires in order to be effective. The parties should not assume that a notarised agreement is the same as a registered transfer of the title to the property.
