Legal and Regulatory Issues[edit]

− In 2003, Judy Thomas of Klamath Falls, Oregon, was awarded $5.3 million in a successful lawsuit against TransUnion. The award was made on the grounds that it took her six years to get TransUnion to remove incorrect information in her credit report.[1]

− In 2006, after spending two years trying to correct erroneous credit information that resulted from being a victim of identity theft, a fraud victim named Sloan filed suit against all three of the USA's largest credit agencies. TransUnion and Experian settled out of court for an undisclosed amount. In Sloan v. Equifax, a jury awarded Sloan $351,000. "She wrote letters. She called them. They saw the problem. They just didn't fix it," said attorney A. Hugo Blankingship III of Blankingship & Associates in Alexandria, Virginia.[2]

TransUnion has also been criticized for concealing charges. Many users complained of not being aware of a $17.95/month charge for holding a TransUnion account.[3]
