Need to erase felony record

You cannot "erase a felony record." It's there forever. Some felony convictions can be reduced to misdemeanors. You can also apply for a dismiss under Penal Code §1203.4, which is sometimes called an "expungement," though it doesn't really expunge anything. See this article on the official California Courts self help website. http://www.courts.ca.gov/1070.htm

You cannot "erase" a felony record. Certain felony offenses ("wobblers") may be reduced to misdemeanor offenses under California Penal Code section 17(b). Once reduced to a misdemeanor, you may seek to expunge the conviction under California Penal Code section 1203.4. If granted, this will change your plea of "guilty" to "not guilty" and your case disposition from "convicted" to "dismissal pursuant to California Penal Code section 1203.4". While you may honestly answer that you have never been convicted of a crime, a record of the case will remain and cannot be sealed. Thus, you cannot entirely "erase" a felony record.

You "heard" incorrectly. There is NO eraser in California. Never listen to legal advice from the guy on the next barstool over. If you successfully completed probation, you may file a PC1203.4 Petition for Dismissal, but it erases nothing.

There is no such thing as erasing a record. If you plead to DUI you may be able to reduce it to a misdemeanor and expunge the case which allows you to not report the conviction in most situations. If this is something you want to do many of us offer free consults.
