query: I cannot find my title insurance policy.

Unfortunately, that may be a problem.  Hopefully, you have your HUD-1 Settlement Statement.  The HUD-1 will identify the settlement agent/title agent on the first page in the top section.  Start by contacting the title agent.  They are the ones who issue the policy in most instances.  If the title agency is no longer in business or not helpful, look on page two of the HUD-1 in the 1100 section.
