Always keep in mind that an ounce of prevention is worth a pound of cure. Consider whether you really want to arbitrate disputes, rather than litigate them. Many people feel that arbitration is less costly than litigation and in many cases that is true. However, there are drawbacks to arbitration. Arbitrators do not need to know or understand the law nor do they need to follow the rules of evidence.
Arbitrators also have a tendency to want to split the baby in half and give everyone something.
Most troubling of all is the inability to appeal the arbitrator's decision except in very limited situations. Online contracts can also be the source of headaches. One final warning, beware of forms and contracts that you may find online. Using those contracts can land you in a heap of trouble. Don't rely on the legal advice given to others, get your own.
