Spelling mistake in mtr 6 challan for stamp duty and registration fees

This is an ignorable typo error, if the name has been spelt properly in all the vital documents, then this will not hamper you in any way.

Ignore such minor spelling mistake and be aware in other documents, especially Sale / conveyance Deed.

Thank you so much Vashista Sir and Kalaiselvan Sir for your reply.  Other documents don't have any such issue. Only stamp duty and registration challan have spelling mistake in surname. If this will not hamper my ownership or will not cause any issue in bank home loan or will not cause any issue in resale in future then I will not cancel agreement and proceed further for home loan application. If bank reject home loan due to this then have to cancel and process refund then do fresh agreement and pay stamp duty and registration again.  Hope bank will approve the home loan.

You don't have to worry about this minor spelling error in the payment challan.

The bank will be concerned only if there is any great error in the title deed, these things are typo, hence banks will not even think about any such issue. 

Thank you so much sir.
