Help needed.. form 15cb

Hello guys,

One of our clients wishes to transfer 1000 dollars to his son residing abroad for payment of tuition fee.

The Bank has asked him to furnish form 15 CA & 15CB.

I would like to ask 2 things here

1) Is there any liability on the client's part to deduct TDS on 1000 dollars

2) What documents we should verify and ask to provide from client for giving a certificate under form 15CB

Please reply

Thank You
