Your Title and Settlement Company arranges mandatory Lenders Title Insurance for your Lender which is an insurance that protects your Lender.
Owners Title Insurance (optional) protects you the Buyer and is highly recommended. There is often a basic Owners Title Policy or an Enhanced Policy with additional protections. Ask your Title Company about cost and which is best for you. You only pay for it once, you get a discount because you also pay for the lenders policy and it is good for as long as you own the home and beyond.
Title Insurance is a good thing. I recommend that you purchase an Owners Title Policy as part of your closing cost.
