Well, I did some checking and spoke to some attorneys/clients and have found the following. Ny State mechanic lien statute has a provision in it for off site work. N Y also allows surveyors architects, engineers, to be included in this process. 
 I understand that the statute states that the work done should increase the value of the property. So how does a survey increase the value of the property? How many refinance have we done that have resulted in monies being borrowed to remodel, or add an addition? How many purchases have we done that have resulted in the house being redone right after the closing. These have all resulted in increasing the value of the property. What if you had to do a search to resolve a r/o/w, encroachment, or boundary line dispute. Would the end result not add value in the homeowner or realtors mind?
 I was amazed to find mechanic liens that were filed by expeditors. Whose only job was to walk papers through and attend planning board meetings for third parties or the homowner. So I don't belive an examiner would be wrong to file a mechanics lien for ''off site" work
 So again think about it, you have a account  who does not pay you. So after waiting and asking the check never comes. You go and file mechanic liens, on say a dozen parcels serve the homeowners. They end up calling the lender, because they paid their bills at the closing. The lender in turn calls the title company. I would think that the title company would not want to lose this account (especially if it is a national account) and would end up paying the examiner to keep the client happy.
 
note; the attorney/clients feel it would be worth trying
