It has property records for most of the home in the US that covered liens, ownership history, mortgage and even tax information.
If you're concerned about a lien placed on your home by your bank, you can check with them. If it's a mechanics lien that you can search on the ccrd.org website.
As previously mentioned though, just because it's not on the website doesn't necessarily mean there isn't one. You must have a suspicion of one otherwise why inquire?
You can also ask an attorney to do a quick search. Sometimes they'll do it for free, depends on your relationship. I may be able to help, call me if you can't find what you're looking for.
