No court would enforce anything like that either. 

@Steven Coppola this is in Windsor Ontario, Canada keep in mind.

WORST THING SHE CAN DO IS TAKE YOU TO COURT, WIN, GET A JUDGEMENT...

With just a note you’ll have to sue in regular court, but of course if he has no money or substantial assets your judgment isn’t worth anything.

Would this clause legally stand up in court? 

I would take it to court (perhaps small claims) and if a judge hears that he did not give you the correct contact info AND he took the next rent check, chances are he will be in hot water.

I have read people getting a lawyers, others going to small court claims and others just going to the sheriffs office?

The amount will dictate whether small claims court is available for the relief you seek.  

Although currently untested, those employing the structure I have described are counting on the fact that the Wyoming Courts will not allow Florida to put a charging order on a Wyoming LLC, thus protecting it's owner.

Put the ball back in their court at first and going to see if that works, if not, i'll evict both for lack of payment.Thanks again.
