What is the purpose of doing a legal search of the title before buying property?
A home is a peculiar kind of purchase. You may be the only purchaser involved, but others may also claim rights to the property. For example, there may be an easement to restrict the use of the land. There may be a tax lien against the property because the owner did not pay taxes. A previously undisclosed heir of a former owner may appear and claim a share of the value. These things can and do occur. A title search of public records will check for claims against the real estate. The best protection against hidden problems is title insurance.
