You must go back to court as soon as possible,appear before the judge,and explain your financial condition.Doing nothing will only get you in more trouble.Did you have a job when you first went to court,and were able to pay these fines and houst arrest charges?Did you lose your job because of this conviction,and can't pay these fines/house arrest fees?What ever the reasons tell the court before you are brought in for contempt of court for non-payment.Good Luck!!!
I absolutely agree with the previous answer. I have seen many people stick their heads in the sand and ignore the problem. This is a sure fire way to end up serving the remaining portion in jail. Be proactive and get to court as soon as possible. That is the only way to give you a chance at a fair resolution. Dress appropriatly so the judge knows you are taking this seriously; look the judge in the eye and tell them the truth of your situation.
