Common title defects include errors in public records, unknown liens, illegal deeds, and unknown heirs. Title defects are issues recorded against a property that could give another party a claim to it. Errors in records from filing mistakes can invalidate deeds or surveys. If a past owner was behind on payments, it creates a lien that stays with the property regardless of new owners. Sometimes deeds are signed invalidly, like by a minor, which affects the chain of title. Additionally, unknown heirs from a past owner's will may later emerge to claim the property. Forged documents could also jeopardize an owner's rights if they give rights to a dishonest party. These title defects must be resolved before selling a property.
