Not disclosing them properly

• Agent or broker is not performing or underperforming - Breach of Duty.

• Client or property is not available, or clients will not disclose needed information to move a sale forward.

• Disagreements over compensation.

• Client wishes to change agents or brokers.

• Misrepresentation, Lack of Full Disclosure or Fraudulent Acts.

• Life events or personal problems creating inability to perform.

   

Violation of fiduciary.

Don't fish of the company pier and you should be good!  Oh and disclose, disclose, disclose.

If one or more parties do not honor the relationship.

none, if you exercise that task properly.....proper representation...

Disclose who is representing who.  Rinse.  Repeat.

Not disclosing.
