The ______________ is a history or list of all recorded owners of a property all the way back to the sovereignty of the soil.

The correct answer is indeed "Chain of title." The chain of title refers to the chronological list of all historical ownership of a particular parcel of real property. It begins with the original sovereign title, which is traced back to the government or the authority that granted the rights to the property. This chain must be clear for a buyer to ensure that the seller has valid title to transfer. A complete and unbroken chain of title is essential in real estate transactions as it establishes the legal right of an owner to sell the property, helping to prevent any disputes or claims of ownership from other parties.

The other options do not fit the definition as accurately. A deed, while important in the transfer of property, is a legal document that conveys ownership rather than a historical record of ownership. A codicil refers to a supplement that modifies a will and has no relevance to property ownership. Plottage describes the increase in value that results from combining two or more parcels of land, which is unrelated to the history of ownership. Thus, "Chain of title" is the most appropriate choice for a comprehensive record of ownership history for a property.
