When you purchase a home (and get a loan), you obtain two title insurance policies:
*Owner's Policy: Insures you, the buyer, against claims against the title. This policy stays in place as long as you own the home.
*Lender's Policy: Insures the lender against claims. Stays in place as long as you have the loan.
In your case, you would still want to obtain your owner's policy and the title company can help you do this.
Issues that affect clear title are referred to as clouds on title. Over the course of the years we have come across these many times, and most times they can be resolved. However, there have been a few instances where they couldn't. That's why buying property at auction can be so risky.
