I am a sub contractor in a public project. after 3 years finally public entity has paid the final payment to general contractor, and even though general contractor has approved the total due, but still is claiming the last 2 change orders which is over 7000, were not approved and refusing to pay those 2. the total due at this time is over 35000, but he is trying to take that 7000 off and pay only 28000. we have proof from Public entity that those 2 are approved and paid. Do i have any option beside hiring a lawyer, at this time? or should i hire a lawyer?
