so has anyone been to court , over what and what was your cost to do so. Was it worth all the time and money?
I assume you are talking about civil court...
We recently finished a year-long legal process to collect payments for our grapes from two of the three largest wineries in Oregon. We went through the state courts and in the end we recovered our payments, interest, and a portion of our legal fees and costs.
If you are seeking a low $ amount and can use the small claims court system, you won't need an attorney and if your case fits into the statutes or common law well and you have good documentation, you are likely to have a positive outcome. If you are trying to recover larger amounts of $s and require legal counsel - even if you think you have the best case and documentation - make sure you ask your attorney lots of questions regarding things like what the attorney thinks your chances of a recovery are, how much will it cost and how much will you likely recover if you settle or if you go to court, etc.
Anytime you get an attorney involved in a court case, you are talking big $'s. Anytime you go to court - even with an ironclad contract and the law on your side - there are human beings making the final decisions about how your particular set of facts fit into the law; these humans don't always see things your way or the way the laws are written. If you go to state or federal court, make sure you understand what you're getting into: time-wise, $-wise, and potential outcome-wise.
We had very tight contracts, Ag Liens, and Lien Foreclosure and Contract laws on our side; we ended up "winning" and spent a boatload of unrecoverable $s on attorneys fees - despite having a very tight attorneys' fee provision in our contracts.
