Any cemetery operator who purchases a cemetery from a city pursuant to sections 214.500 to 214.516 shall not be liable for any wrongful interments or errors made in the sale of plots prior to the cemetery operator’s purchase of the cemetery, nor shall such cemetery operator be liable for multiple ownership of plots sold by such cemetery operator due to a lack of adequate records in such cemetery operator’s possession at the time of such cemetery operator’s purchase of such cemetery from the city, provided the cemetery operator offers a plot of equal value for the interment, if such party can prove ownership of the right to bury a person by presenting a contract for the right to burial.
