Hello eur3118o and welcome to JustAnswer.
There are two different procedures that apply to recovering money in situations such as this. One applies if you are charged with a related criminal
offense; the other if you are not. Can you tell me specifically what you were cited for? I'm guessing 11357, subd. (c), of the Health & Safety Code, but the correct procedure to follow depends on the exact charges and likely court proceedings going forward.
When is your court date and what county did this occur in?
You should also have been provided with a receipt for your money, as well as forms for filing a claim. Did you get them?
Unfortunately, there is no "speedy" way to get your money back unless the cops can be convinced that the money is clean. It might be worth trying to do that, by way of having an attorney contact the CHP directly. However, it is more likely that you will have to do it as part of the court proceedings on your citation.
I have handled several of these types of cases in my private practice. The DA's office will likely try to "forfeit" at least some of the money as part of the legal proceedings. This is nothing more or less than a money grab and you almost certainly will need an attorney to help you out with this. In the end, if you can provide documentation which shows that the money was not the proceeds of drug sales, you will probably be able to get it all back, but it will not likely be an easy process.
If you will provide the additional information requested above, I can give you a more detailed response. I will, however, be away most of the day tomorrow making a court appearance in Monterey County, which is about 3 hours away. If you reply, I will pick it up when I get back from court, probably in the late afternoon, California time, and will get back to you shortly thereafter.
