An opinion of title, a certificate of title, a Torrens certificate, and title insurance are all examples of:

The items listed—an opinion of title, a certificate of title, a Torrens certificate, and a title insurance policy—are all forms of title assurance. Their primary purpose is to provide proof or verification of the ownership rights to a specific parcel of real estate. They serve as evidence that the title is marketable and to identify any known liens or encumbrances. Each represents a different method of examining public records and certifying the condition of a property's title for a prospective buyer or lender.

A. cloud on a title: A cloud on a title is a claim, lien, or encumbrance that impairs the owner's rights, making the title questionable, not proving it.

B. equitable title: This refers to the interest held by a buyer under a sales contract, granting them the right to obtain legal title, not the proof of existing legal title.

D. chain of title: This is the historical succession of property owners. It is the record that is examined to produce evidence of title, but it is not the evidence itself.
