In the money nifty option on expiry

If i have one nifty sold option and one nifty buy option in the spread of 100 points and these two options expire in the money on expiry day but I left them open didn’t square off on my own.
I know that for both the options one debit and second credit bills will be made but I want to know is there some higher charges will be debited in this case than when I square off them on my own in the market?

Only the brokerage charge of 20 per trade will be extra if you square off yourself.
