The Petition for Dissolution of Marriage is the initial document filed with the Montana court. It is in the document that the filing spouse will request the court to terminate the marriage under certain specified grounds.

No-Fault Based Grounds:
(1) The marriage is irretrievably broken; (2) Living separate and apart for a period of at least 180 days prior to filing; (3) There is serious marital discord that adversely affects the attitude of one or both of the parties towards the marital relationship. (Montana Code - Section 40 - Titles: 4-104)

Every dissolution of marriage case that is filed in the state of Montana must declare the grounds in which the dissolution of marriage is to be granted.
