How can I find out if there is a Les Pendence on my property and who filed it?

County Clerk should have, I would do a Google Type search and enter (your county your state public records. I use no commas?
Can you tell County and State?

Lis pendens


(1) Latin for "a suit pending." The term may refer to any pending lawsuit. (2) A written notice that a lawsuit has been filed concerning real estate, involving either the title (http://www.nolo.com/definition.cfm/term/CBEF1C79-03B7-49D4-97246CF490328679) to the property or a claimed ownership interest in it. The notice is usually filed in the county land records office. Recording a lis pendens against a piece of property alerts a potential purchaser or lender that the property's title is in question, which makes the property less attractive to a buyer or lender. After the notice is filed, anyone who nevertheless purchases the land or property described in the notice takes subject to the ultimate decision of the lawsuit.

You will have to go to the register of deeds ( or similar name in your area) and check to see if there has been a notice of pending law suit filed. Also of course the fact that someone should be also serving you with a notice of a law suit.
