<human>: Can you summarize the given text in a few sentences?

Someone owes me a substantial amount of money and has agreed to pay the full amount. My problem is that I am moving out to Colorado from Michigan in the coming months. I really don't trust him to pay me once I move and have given filing suit a fair amount of thought. I am beginning to run out of time to do so and definitely would not like to deal with a legal battle while trying to move out of state at the same time. My question is do I need to file suit in MI, where the dispute took place, or can I do so once I move to CO?
<bot>: Guy owes me money. Can I file suit in CO where I am moving or do I need to file in MI where dispute took place?
