Depositors will have to list:

• how many notes they’re depositing
• why they didn’t deposit the money earlier 
• what is the source of the funds

Here’s what a form being handed out at by Banks looks like: 

This form is in addition to the fact that bank officials are required to question the person making the deposit as to why it wasn’t done earlier and the explanation has to be deemed ‘satisfactory’. 

The depositor is also required to carry identity proof, a copy of which has to be left with the bank, 

Bank officials are also to keep the explanation on record for future audit and ensure that no more deposits are made in future.
