Check with your Associations attorney. Typically an Association may go through small claims or other court to be awarded a judgement but it may also depend on how the Associations governing documents are written and applicable State laws.
Please note that winning a judgement in court does not result in automatic money for the Association. It may open up other avenues to collect the money due (like garnishing wages or bank accounts) however an additional court order will be required to do those things.
Here are some links about collecting judgements, etc. in Missouri:
