That is so interesting to me that you automatically assumed Davis was her middle name.  I do not know that I agree that it is "obvious" that Davis was her maiden name, unless there is say a deed in the search from Lisa Johnson, fka Lisa Davis, or  Lisa Davis to Lisa Johnson f/k/a Lisa Davis to  Lisa Johnson and Bob Johnson, or something else that would be a tip off.

Personally, I would have provided all liens against Lisa Johnson and anything against Lisa D Johnson.   I would not have provided any judgments against Lisa (all middle initials indexed) Johnson because to me the way the post was written, I think it is a fair assumption that the middle name starts with a D.  

You did not say how the lien was indexed so I am assuming it was against Lisa (?) Johnson. 

I think a bigger mistake that I see more often is abstractors eliminating judgments based on address.  I agree that you shouldn't eliminate by middle initial or SS# even if it's given to you.  What if the person typing it made an error.  Let the title company or attorney call and have the lien holder tell them NOP, that is not a call I wish to make as that can be an extremely expensive mistake for the small amount of money that is paid per search. 

 I am not sure how that is going to go on an E&O claim, since (based on the post) you could make the case that the lien wasn't findable based on the information provided.  How was it found ( for them to tell you about it)?  Credit report? Possibly on a Charles Jones report?
