Hi, and welcome to Just Answer. Thank you for entrusting me with your legal issue. I will do my best to assist you. During the course of our interaction , I may need some additional information. Also, please keep in mind that when any of us at JA legal answers a question, we don't know what you, the customer, already knows about the issue unless we are told.
The spelling of your name will not void the ticket. Police can exceed the speed limit to catch up with a suspected speeder. Radar is documentary evidence of course. Here it would be your word against his...the judge would have to decide and I suspect the officer may well prevail on that issue.
All that said, I suspect that the $1,200 includes some penalties. If the basic ticket is lower and you may be able to reduce the penalties, compare the possible benefit against the cost of hiring a lawyer and make a business decision.
Please advise me of your state and nearest large city, and I will get you a link to a directory we lawyers use to find highly qualified legal specialists in various fields. These lawyers are in the directory because they are rated as QUALIFIED by other lawyers in their field of expertise and geographic area. Look through the websites and call a few firms you feel are appropriate for your case.
