Title Insurance

Generally speaking, title insurance indemnifies the property owner and their lender against loss due to: 1. Recorded Liens, 2. Defects in the Title, and 3. Lack of access to and from the land. The most common policies used by residential property owners are the California Land Title Association (CLTA) standard coverage policy, the American Land Title Association (ALTA) residential policy, and American Land Title Association (ALTA) owner's policy. CLTA policies generally offer the least amount of coverage.  
If you don't understand title insurance you should consult with your title company and/or a real estate attorney. Like most things in life that require insurance, title insurance isn't problematic unless you have cause to need it.  In which case not having the appropriate coverage could be quite costly and result in significant legal consequences.
