is there any specific technique or language that is being used that works best?

I can see that I need to revise my lease language to note that any payments go to late fees first.As of today, the tenant hasn't paid any October rent. 

We also have very strong language in the lease about smoking in the home (I don't think it would hold up in court) and this acts as another deterrent.

The LLC Operating Agreement needs to be drafted in such a manner as to convey certain IRS compliance language that will allow the IRA custodian to accept the LLC as an investment of your IRA.  

The argument you are providing is certainly one that could be brought up before a Judge, but I think the nature of the language of the UPL rules would support the idea that, by explicitly omitting language related to the U.S.

@Ben Rice I would also add that speaking your landlord's language wouldn't hurt.

It is usually controlled by the language in the code. 

@Charles David $10.00 and other good and valuable consideration is typical language, as @Jay Hinrichs mentioned. 

But one of my hobbies is reading books about body language and deception detection.  

The short sale addendum has language that warns all parties of the need to get creditor approval and the fact that the sale may not go through and that if it does that it could take an extensive amount of time to do so.I'm finding that less and less short sales are being approved these days.
