Curious about your question? Are you wanting to establish evidence of something, or are you trying to establish a "claim"? If it is the latter, depending on the situation you may be able to file a mechanics lien on the title of the property (for any work done) and/or file a small claims suit.
Understanding a little more on the background on your question will elicit a more in depth and accurate response.
