There's no such thing as enforced or being carried out. If there are then those Malay Muslims whom are caught & found eating during fasting month would be in trouble. & you would see raids in those cheapo hotels by the Islamic Officers.
The law only covers certain aspects of a Muslims (divorce (but if cannot settle amicably still being point back to family court), deeds & a few more here

Don't try to misaligned others coming to a conclusion that Syariah Laws are the same as Hudud Laws...these 2 are 2 different laws.
I'm assuming TS is a convert & wants to renounce Islam & also might be caught in a divorce situation which in this case have to follow Syariah Law but again if cannot resolve Syariah Court will get both parties to attend Family Court(I'm assuming OK).
