I am filing a civil restraining order on my roommate, can my criminal record be used against me?

A lot will depend on what type of felony you committed - from your statement I am assuming you were convicted, not merely arrested. A crime committed within 10 years is going to be considered by the Court and can't easily be evidentiarily excluded. I suggest you contact a local attorney to at least consult with before moving forward. The response given is not intended to create, nor does it create an ongoing duty to respond to questions. The response does not form an attorney-client relationship, nor is it intended to be anything other than the educated opinion of the author. It should not be relied upon as legal advice. The response given is based upon the limited facts provided by the person asking the question. To the extent additional or different facts exist, the response might possibly change. Attorney is licensed to practice law only in the State of California. Responses are based solely on California law unless stated otherwise.
