If someone agrees to pay (or pay a share) at the time they sign on to the plan, then they owe the money by default, unless I or they find a replacement person. But that's the expectation by default; I can say they don't owe anything (and I very often do, because I have more spare money than most friends), or they can ask if it's okay to cancel and not pay and I can agree.
