Resignation from a limited contract to take another offer

Hi!

I need your suggestion and advice regarding my case. I'm about to file a resignation letter to my current employer. I was working with them as a regular employee for 5 years.

Previously, I signed a new limited contract for 2 years and I got a new offer letter to a new company.

May I know what are the sanctions they will file on me once I file my resignation and also my 1 month notice period?
