(a) If an assignor collects rents that the assignee is entitled to collect under this chapter, the assignor shall turn over the proceeds to the assignee not later than the 30th day after the date the assignor receives notice from the assignee under § 64.054 or within such other period agreed by the assignor and assignee in a security instrument or other document, less any amount representing payment of expenses agreed in that security instrument or other document.
(b) In addition to any other remedy available to the assignee under a law of this state other than this chapter, if an assignor does not turn over proceeds to the assignee as required by Subsection (a), the assignee may recover from the assignor in a civil action:
(1) the proceeds, or an amount equal to the proceeds, that the assignor was obligated to turn over under Subsection (a); and
(2) reasonable attorney’s fees and costs incurred by the assignee to the extent provided for by an agreement between the assignor and assignee and not prohibited by a law of this state other than this chapter.

(c) The assignee may maintain an action under Subsection (b) with or without taking action to foreclose any security interest that the assignee has in the real property.
(d) Unless otherwise agreed, if an assignee who has a security interest in rents that is subordinate to the security interest of another assignee under § 64.052 enforces the subordinate assignee’s interest under § 64.054 or 64.055 before the assignee with priority enforces the interests in rents of the assignee with priority, the subordinate assignee is not obligated to turn over any proceeds that the subordinate assignee collects before the subordinate assignee receives a signed notice from the assignee with priority informing the subordinate assignee that the assignee with priority is enforcing the interest in rents of the assignee with priority. The subordinate assignee shall turn over to the assignee with priority any proceeds that the subordinate assignee collects after the subordinate assignee receives the notice from the assignee with priority that the assignee with priority is enforcing the interest in rents of the assignee with priority not later than the 30th day after the date the subordinate assignee receives the notice or as otherwise agreed between the assignee with priority and the subordinate assignee. Any proceeds subsequently collected by the subordinate assignee shall be turned over to the assignee with priority not later than the 10th day after the date the proceeds are collected or as otherwise agreed between the assignee with priority and the subordinate assignee.
