When you buy a home, you are buying the title to the property. It is sometimes also referred to as a deed. Your lawyer registers you as the owner in the land registry system. Having "good title" to your property is important because it protects your investment so that you will be able to sell your property or obtain mortgage financing.
Title insurance is unlike any other kind of insurance. It is not house insurance, which protects the contents of your home or its structure, and where you pay a monthly or annual premium. Unlike house insurance, you only pay a one-time premium with no deductible for title insurance, which protects your ownership or title against losses incurred as a result of undetected or unknown title defects for as long as you own your home. Even if you are the rightful owner of your home, there are instances such as real estate title fraud when your title can come into question.
