What about liability?

Being in a TimeBank is no different than helping your neighbor.  Every member in the TimeBank assumes all responsibility for their exchanges just as you would treat a friend or a neighbor.  Although homeowners insurance protects members, some TimeBanks have volunteer liability insurance to cover problems that can occur during a service exchange.  However, in the decades that timebanking has been around, no claims have ever been filed against it. Timebanking is based on trust and reciprocity.
