BenRar,
If you are the owner/operator of your company then yes this is something you would need to know for the area(s) you are operating in if your don't have specific verbiage in the contract for how these types of situations are handled.
Typically, if I engage a lawyer I would make sure that I have all the scenarios that may arise or at least as many as I can think of so that you know how each one is handled. Also, ask the lawyer what you would need to provide to them should you need to enact upon any of their legal counsel for any of those situations.
Thanks,
TE
