BE ON TIME. The last thing you want is to be so late that a warrant is issued for your arrest. Better even, be early. Kansas courts typically call those with lawyers first but, that doesn't mean you shouldn't already be present if you don't have one.
DRESS APPROPRIATELY. You don't have to show up in a suit but, make sure your clothing is respectable and clean.
BE POLITE TO EVERYONE. Whether it's the court clerk, District Attorney, etc. you should use your manners in your interactions with them. That includes using an appropriate tone and volume while waiting inside/outside of the courtroom.
DO NOT ENTER A PLEA. Your first hearing should simply be an advisement of your rights and the crimes you have been charged with, and setting of your bail. If you are asked to enter a plea of guilty or not guilty request legal advise first.
UNDERSTAND BAIL. Depending on what county you were arrested/charged in the conditions and type of bail you qualify for may vary. Pay close attention to, and adhere to, any conditions of your bail (ex. reporting to probation, getting an evaluation, etc.). Failure to do so will only compound your already scary circumstances and could result in you being taken back into custody.
REQUEST/HIRE REPRESENTATION. Your freedom and rights need to be protected. Without proper legal advise you are risking your future. You may think you cannot afford, or don't need, an attorney but, you are wrong.
