You don’t want problems from prior ownerships to interfere with your rights to your property. And you don’t want to pay the potentially ruinous cost of defending your property rights in court.
A title insurance policy is your best protection against potential title defects, which can remain hidden despite the most thorough search of public records and the most careful escrow or closing.
For a one-time premium a title insurance company agrees to reimburse you for loss due to defects existing prior to the issue date of your policy, up to the policy amount. And, should it be needed, the policy also provides for the cost of legal defense of your title.
