You Title insurance is a one-time premium paid to a title company that guarantees that you own a particular piece of property and guarantees that no one else has a claim to that property. You can't tell by looking at a property or at the deed whether the title to that property is good, and no one will require you to obtain title insurance, unless you are obtaining a mortgage. Title insurance works the opposite of your health or home insurance, which pays for loss or injury occurring after the effective date.
Title insurance pays for events which occurred before the policy's effective date.
It is the best protection you can have against any claims that may arise out of the past. You may wonder what can go wrong once you have a deed to the property in hand. The deed is recorded at the County Recorder's office, everything looks official, and an examination of the property shows no visible signs of encroachment or problems. You have walked the property, verified the survey, and see no boundary disputes. You could even go through the county records, if you wanted to do so, and check for any possible problems.
