Missouri is no-fault. The court grants a dissolution when the marriage is irretrievably broken.
You can allege an irretrievable breakdown. If the other spouse disagrees, the judge can still find breakdown based on facts such as adultery, abandoned marital obligations, or living separate and apart for 12 months with mutual consent or 24 months without consent.
Missouri does not require you to plead fault to dissolve the marriage. Conduct may be considered among many factors when deciding property division or maintenance, but it rarely drives the entire outcome.
