I think title insurance covers any liens or encroachments against your property. The title company does a search for liens, and if there is one, you would not be able to go through with the loan (the mortgage company would deny the loan until the issue gets fixed)
Since you are buying a condo, I imagine that there are no encroachments that you need to worry about. A lien would be possible, though. For example, if the previous owner put in new kitchen cabinets and counters and did not pay the contractor, the contractor could put a lien against the property.
If your loan is going through, and title is clean, you have nothing to worry about.
But you DO have to pay for the title company to do that search and to issue the certificate. Some title companies are better than others and in most states I believe you as the buyer are allowed to choose your title company.
