If I’m being charged with theft 2nd offense and unlawful use of a motor vehicle my 1st offence can I get probation?

It's possible to obtain probation, but this ultimately depends on the facts of your specific case. With this being your second theft offense, the chances of receiving favorable probation terms or even probation at all is less likely, but no one can guarantee that you will receive probation. Whether you can receive probation will be left up to the discretion of the prosecutor and/or judge.
