It's good that you have an attorney working for you on the case. It is possible that they revoke your probation and make you serve the terms of your underlying sentence. I would recommend doing any and everything your attorney tells you. And don't do anything else to violate the terms of your probation.
As Mr. Davies stated, as of July 1st, it could be possible to get that offense removed. There is a 10 year waiting period, but expungement could be an option in the future, where before July 1, 2011, it was not possible at all to expunge a dui from your record. Contact a Kansas attorney to help you address your possible options.
The decision on whether or not to dismiss the case rests solely with the Prosecutor. You can approach them with your wishes, and it's possible that they may choose to dismiss. If your bf does have an attorney I would agree with Attorney Lewis that you should consult them as soon as possible.
Yes this is very common. The first test at the car is a PBT (Preliminary Breath Test). There are numerous types of machines that police use for this test, they are notoriously inaccurate, which is why as Attorney Lewis said they aren't admissible against you for guilty or innocence. However the test at the station is an Intoxilyzer 8000, and is admissible in KS as long as the proper procedures were followed. Consult a local attorney to discuss your case in more detail.
This will be treated as your first as long as you don't have any priors on your record. Contact a local attorney. Johnson County District Court is one of the worst places in the state to be charged with a Domestic Battery case.
I recommend you contact a local attorney as soon as you can. By Deferred Judgement Program, I assume you are referring to some type of a Diversion program, which would avoid jail time. However, you should consult an attorney to review the facts of the case against you. There is a possibility you would have a case you would want to take to trial. Best of luck.
