Montana Code Annotated · § 70-24-423 — Waiver of landlord's right to terminate for breach

Acceptance by the landlord of full payment of rent due is a waiver of a claimed breach of a rental agreement only when the claimed breach is the nonpayment of rent. Acceptance of full payment of rent due when a claimed breach is something other than the nonpayment of rent does not constitute a waiver of any right. The acceptance of partial payment of rent due does not constitute a waiver of any right, including rent due.
