The function of the title company is to ensure that your new home is legally yours following closing. The title company will research your property's prior ownership history and once the search is completed this will enable you to purchase a Title Insurance Policy. This protects you, should someone makes a claim to own all or a portion of your property.
Title insurance protects against many types of risks, including:
Forged deeds or other documents
Claims by previously undisclosed heirs
Inaccurate descriptions of property and boundaries
Mistakes in public records
Fraudulent acts
The cost of this title insurance policy is usually factored into your closing cost.
