If the moving cost is higher on moving day, you are not necessarily obligated to pay the additional charges at that time. According to the Federal Motor Carrier Safety Administration (FMCSA), you are not required to pay more than 100% of a binding estimate (or 110% of a non-binding estimate) for any price increases after the moving truck has been loaded. The mover is required to bill any additional charges 30 days after delivery of your goods. A company cannot refuse to deliver your items due to non-payment of any added charges, which can be incurred if the inventory you provided ahead of moving day is incomplete or inaccurate. If you feel you have been hit with extra fees unfairly or a company will not deliver your possessions, you can file an online complaint with the FMCSA or contact the organization at 1-888-368-7238.
