I was arested about a year ago for petty theft. I pleaded no contest to it and was wondering how I would get the conviction either sealed or expunged. I was 18 at the time and will be on probation untill I turn 22. I have figured out thus far that I need to complete my sentence, but what else needs to be done. Also is my conviction one that can be sealed or expunged. I live in California and my record is immaculate besides that one conviction. Any help is appreciated.
