Lamptey married Gloria Appiah in 1993. The marriage was a controversial one, angering his brothers, as Appiah is from a different tribe (Fante) to his (Ga). He had five children, of whom two died to lung diseases. However, a DNA test revealed he was not the biological father of the remaining three children and he divorced her. Appiah filed for an appeal in court, requesting 50% of his assets in the divorce including occupancy at the couple's East Legon apartment, but was refused by the judge.
