Chancery Causes are cases of equity. According to Black's Law Dictionary they are "administered according to fairness as contrasted with the strictly formulated rules of common law." A judge, not a jury, determines the outcome of the case; however, the judge is basing the decision on findings compiled and documented by Commissioners. Chancery causes are useful when researching local history, genealogical information, and land or estate divisions. They are a valuable source of local, state, social, and legal history and serve as a primary source for understanding a locality's history. Chancery causes document the lived experiences of free and enslaved individuals; women; children; people living with physical disabilities or mental health struggles; people living in poverty; defunct institutions and corporate entities; or those that may not have otherwise left traditional written histories.

Southampton County was named, in the opinion of many authorities, for Henry Wriothesley, third earl of Southampton and treasurer of the Virginia Company of London from 1620 to 1624. It is more likely, however, that the county was named for the borough of Southampton in England. Southampton County was formed in 1749 from Isle of Wight County, and part of Nansemond County was added in 1786. The county seat is Courtland.
