What system is used to index names of grantors and grantees in real estate transactions?

The Grantor/Grantee System is the correct choice because it is specifically designed to index, track, and record the names of grantors (sellers) and grantees (buyers) involved in real estate transactions. This system creates a clear and organized method for documenting and retrieving information about property transfers, enabling easy access to public records.

In this system, grantors have their names listed as they convey property rights, while grantees have their names indexed when they receive those rights. This dual listing not only helps maintain transparency in property ownership but also assists in establishing clear chains of title, which is crucial for legal and historical reference in real estate markets.

The other options, while related to property and real estate, do not specifically refer to the systematic indexing of the parties involved in transactions. For example, the Title Index System and Property Ownership System might focus more broadly on properties or titles without emphasizing the specific categorization of grantors and grantees. The Real Estate Register could suggest a collection of real estate facts but does not define the indexing process of transaction participants like the Grantor/Grantee System does.
