I waiting your kind reply

First of all very thanks for your kind reply.
Mam please Take a glance once more on my query and please answer remaining part of my query.
I mean, It’s very clear that clubbing provision and limitations are not applicable between very near relatives, in my query Mother and son ,
But mam are It’s not fall in clubbing provision if mother do trading and earning. Hence mother report all his gain as per income tax law. And is it mandatory or any provision like Gift deed or any other gift transfer relative documents to be draft.
Thanks and regards again
