Misty,
In reality FSBO's are not the #1 reason for lawsuits, Lawyers are!
You are correct the everyone on this board does not know specific CA law regarding disclosures but disclosures were not the topic of the thread you referring.
Many states have very similiar disclosure laws so do no jump to the conclusion that just because someone is not from CA they have zero knowledge and many of us know agents & brokers from CA and a few may have been previously licensed in CA.
Would love to see your statistics to back up what you are claiming about the FSBO lawsuits. If it is just your opinion then ok but you should say that it is just that an opinion.
