The “joint control rule” means that when an owner or general contractor writes a joint cheque to a subcontractor and the subcontractor`s equipment supplier, the equipment supplier who approves and deposits the pooled cheque certifies that all amounts due up to the date of the joint review have been paid. On the contrary, joint cheque agreements are a creature of the treaty. In the United States, all parties have the general freedom to enter into contracts for whatever they want. The law only marginally restricts this freedom in order to prohibit people from violating public order (i.e. going into slavery, murder, or “no instructions”). The application of a pooled cheque agreement can be the whole dispute. Often, however, this is only a tiny part of the conflicts between the parties. .
