Is purgatory after last judgment

Purgatory, in Catholic theology, is understood as a state of purification for souls who die in grace but still need to be cleansed of venial sins before entering heaven. It is not seen as occurring after the Last Judgment; rather, it is a temporary state for souls before they attain the beatific vision of God. After the Last Judgment, there will no longer be a need for purgatory, as souls will be definitively separated into heaven or hell. Thus, purgatory is relevant only prior to the final judgment.
