About " c " form

Your question is not clear

i want to say that if i am regesterd deler i sold some goods against c form to other party and c form provided by party against sale than what is procedure of " c" form

Do you mean after you have received the C form from the customer, what action you need to take? If yes, here it is:

1. You need to submit original form to the CTD
2. Procedure differs from state to state
3. Before submitting the original form to the Dept, you need to upload the relevant particulars of the C form on the VAT portal and generate acknowledgement
