(2) is subject to another qualified domestic relations order or similar order;

(3) is property that is the subject of a pending proceeding for dissolution of a marriage;

(4) is property disposed of in a previous decree for dissolution of a marriage; or

(5) is the subject of an agreement under Chapter 4.

(c) A court described by Subsection (a) retains jurisdiction to render a qualified domestic relations order or similar order under this subchapter until all maintenance due under the maintenance order, including arrearages and interest, has been paid.
