The only thing you have to do in order to qualify for a PD is show up and make less than $2000/month. The process is very streamlined and automatic. Good luck.
If you have no money, you will qualify for the Public Defender in a criminal case. You cannot get a PD for a civil or family law matter such as a TRO.
