stamp duty fraud in which not paying stamp duty at all or deliberately paying less stamp duty?
Not sure about the court case thingie how will it works, but I have check with the stamp office for solution. Apparently it isn't rocket science, you just have to pay the penalty and re-stamp it shall do. The penalty isn't as expensive as it may seem too. So it's ok. This is quite common back in the days where law firms have rely on their dispatch to do the stamping.
So the lesson I've learnt and would like to share with you guys are simple, next time after your documents are stamped, kindly login the website to ensure the stamp duty is authentic and paid.
