(1) Except as otherwise provided in subsection (6) of KRS 403.180, the provisions of any decree respecting maintenance may be modified only upon a showing of changed circumstances so substantial and continuing as to make the terms unconscionable. The provisions as to property disposition may not be revoked or modified, unless the court finds the existence of conditions that justify the reopening of a judgment under the laws of this state.
(2) Unless otherwise agreed in writing or expressly provided in the decree, the obligation to pay future maintenance is terminated upon the death of either party or the remarriage of the party receiving maintenance.
