Before you pack, you should clean up and sort through your things to ensure that moving goes smoothly. Please list the things you don't need anymore and think about giving them away or selling them. Please list everything you own and label each box with its contents and the room it goes in. Also, you should gather important papers like your insurance certificate, estimates, bills, and an inventory list.
If you want to move, plan a few months ahead. From June to August, when 80% of moves happen, summer is the busiest time for moving companies. During the rest of the year, you only need to give a moving company 2-4 weeks' notice for a local move and 4-6 weeks' notice for a long-distance move.
You can file a complaint with the Federal Motor Carrier Safety Administration (FMCSA) or the Missouri Department of Transportation if you think a moving company cheated you. You should also talk to a lawyer for legal advice.
You should be there when your things are loaded and unloaded, but you don't have to be at the destination. You can send someone else to pick up your things if they have the right information and permission.
