Question regarding research for buying property through Auction

[Amir Saeed]

I a new to property auctions. I have gone to few auction and still learning the process. I do not want to start until I have understood most of the process.
Question I have is that how can I find out the details about a property, specifically about any unpaid liens. My county post the land records online but all I am able to see is the "Deed of Trust". I am looking for any liens that are against the property. Where can I get the most up to date information. Pls assist.

Thanks
