Listen very carefully, if you don't defend yourself, under Illinois' Parentage Laws, you will be declared the father - EVEN IF YOU ARE NOT. You will have a child support order entered against you, if you miss 90 days worth of payments they suspend your license. Miss more than that, and the sheriff will find you and take you to jail until you pay. Again, if they declare you the father because you "no-showed," you will not be able to undo that after 30 days. Not even being able to raise johnny Cochran from the dead as your attorney will save you.
Do I have your attention? Good.
Beg, borrow, work, or whatever - but understand this: You are on trial for your life, and if you don't take that seriously, your life will forever be ruined. Too many people ignore parentage summons, get cuffed, and add to our already overcrowded jail populations.
Owing arrears bars you from most city, county and state employment opportunities. It will go on a background check that a prospective employer might run. In short, it will destroy any chance of you actually working something more than a minimum wage job.
Man up, because until you deal with this, it's on like Donkey Kong.
