I have 2 shoplifting charges in MA and got one in NH, will that count against me when I go to court?

All prior offenses will count against you. However, they will only run the triple III (out of state query) if they know you lived in two states. I would advise you to tell the truth if asked, but do not volunteer info about out of state convictions unless asked.

If NH learns of MA charges they will likely look for a higher penalty. Frequently NH will only run NH criminal record. Do not disclose MA record or talk to state.
