1. Virginia Real Estate Board. (2023). Virginia Real Estate Manual (2023 ed.). Virginia Department of Professional and Occupational Regulation. Chapter 6, "Transferring Title," pp. 6-6 to 6-7. The manual states, "A quitclaim deed provides the grantee with the least protection of any deed. It carries no covenants or warranties and conveys only such interest... that the grantor may have when the deed is delivered."
2. Code of Virginia. Title 55.1. Property and Conveyances. While the code does not explicitly define a quitclaim deed, it defines the covenants of warranty that are absent from it. See § 55.1-354 ("Effect of covenant of 'general warranty.'") and § 55.1-355 ("Effect of covenant of 'special warranty.'"). The absence of these covenants in a quitclaim deed is what removes liability from the grantor.
3. French, D. P., & Sizemore, D. (2019). Virginia Real Estate for Salespersons (7th ed.). OnCourse Learning. Chapter 8, "Title and Conveyancing." This university-level textbook, often used in state-approved licensing courses, explains that a quitclaim deed is a "deed of release" that contains no warranties and is used to convey less than a fee simple estate or to cure a cloud on the title.
