20-10  The term in good standing is introduced but not defined. 

20-55:  A broker seeking to exchange "the" broker's license...  I would suggest you replace "the" with "their".  

20-165(4): what is a timely manner?  This is very broad and will allow members of the public to file frivolous complaints.  I would suggest that you consider adding the concept of "reasonableness":  Respond within a reasonable time to inquires from the public....  Reasonable is a well established concept that has been defined by many courts. 

20-181.  (A)(1)(c):  Should use the consistent term of signatory authority instead of escrow account authority which is introduced under this subsection but not used in the other ones.  (B)(1)(a): an earnest money deposit received by the principal broker or supervising broker or "the broker's associates".  Who are these associates?  This is not a defined term.  Does that mean the title company designated in the contract? Is it the salesperson or other brokers/licensees affiliated with the firm?  If that is the case, then lets use consistent nomenclature so as to not create confusion. 

20-190(3).  The requirements in this provision, specifically the one which requires an update to the property's contract status will most of the time be subject to the control of third parties.  In (4) you added a sentence addressing this.  I would suggest you add the same sentence at the end of (3).

20-260(g):  This is very complicated to understand.  Given what was deleted, I believe it is targeted towards PM done through unlicensed firms by licensees.  Are you stating in this section that a salesperson/broker is allowed to act as a PM so long as they have ownership interest in the PM company even if the entity does not have a firm license?
