I have a fine of $373 and court costs. How long do i have to sit in the brown county jail of ainsworth nebraska to have those fines taken care of?
Generally, the court will determine how long you have to 'sit in jail' if you choose not to pay the fine and court costs. If the matter has been to hearing ( I assume it has), then court likely told you at that time what your options were.
You don't indicate whether you had an attorney. If you do, check with that attorney. You can also contact the court clerk, who will have a record of what happened at the hearing.
