Name correction in challan mtr form 6

Get a rectification deed from the builder for name correction, which is important.

Thanks for your reply Sir.

Since mistake is in challan and not in agreement papers, how rectification deed help in getting name update in e-gras system?

If e-gras shows wrong name for challan, then technically it is not registered with us.

How to get e-gras system with correct name?

Where did you remit the challan amount? You ask them how to rectify it.

It is filled by lawyer firm online through e-gras system.

And they used totally incorrect surname for my wife.

No. already remitted through e-challan by mistake.  The mistake occurred while typing the name.  So it is firm's mistake.
