I'm not sure an attorney will be able to provide the kind of help you need. There is no legal remedy available to force your brother to repay you for what amounted to an illegal act (making a false statement).
The information provided in this answer does not create an attorney-client relationship and is not considered to be legal advice.
I will give this a shot, as there is a lot of missing information. Number one I am confused with what you were convicted of?
It sounds like you were convicted of (1) Sale or Transportation of Marijuana (ARS 13-3405)…which could be anything from a class 2 felony to a class 4 felony depending on what the amount of MJ was (there are only 6 classes of felonies here in Arizona). If you also convicted of (2) Sale or Transportation of a Narcotic Drug (i.e. cocaine)(ARS 14-3408); you are looking at the same classes of felonies. But if you did 2 years in prison…I am guessing we are talking about 2 counts…maybe class 4 felonies?? Again, you need to go over your paperwork to determine what counts you pled guilty to. Why am I making such a big deal about what you pled guilty to these crimes 27 years ago?
Because you need to get your “civil liberties” reinstated. If these crimes were committed in either Maricopa County or Pima County there are PDF forms available online to achieve that goal. See: clerkofcourt.maricopa.gov/eformsondemand/300.pdf
Getting your civil rights as defined in ARS 13-904 reinstated will help when filling out employment applications and will make you feel better about yourself.
As the other attorney wrote, you need to get counseling for what happened to you as a teen. Victims of sexual abuse need to deal with the trauma. I feel that it your biggest obstacle to moving past these issues with your brother. I would not get married until you see a therapist regarding this trauma.
