The longest court case in history lasted over 1,000 years in England.

The case known as the 'Cadaver Synod' or more broadly medieval land disputes sometimes extended over centuries due to the slow legal processes and changes in ruling powers. The most famous example is the dispute over the ownership of the manor of Pendle in Lancashire, England, which reportedly lasted more than 1,000 years, starting in the 12th century. The case involved many generations of families and multiple appeals as laws evolved over time.
