It is an agreement which is entered into between the parties for dealing with the property and which creates a right to obtain a sale deed mentioning the property. Normally it fixes a time for completion, payment of earnest money or part payment of purchase consideration. Generally it is a document that precedes a sale deed and in such cases does not require registration and will also not confer any charge or right on the property. However in some states the sale agreement itself will be registered and will act as a sale deed.
