Colorado has two limitations periods that could apply to a consumer debt, and which one governs a credit card balance is genuinely contested rather than settled. That ambiguity is the most important thing to understand about collection timing in the state, because a three year difference decides whether a claim is live or dead.

Yes. A signed written contract is not required for a debt to exist, to be collected, or to be enforced in court. Plenty of enforceable obligations never involved a signature at all. What the absence of a written contract actually changes is the time limit for suing and how hard the claim is to prove, and both of those can matter a great deal.

Co-living looks like one property with several residents, and legally it is usually several tenancies that happen to share a kitchen. How the agreements were written determines whether you can remove one resident without touching the others, what you can collect from whom, and in some jurisdictions whether the arrangement is lawful at all.

The Debt Collection Improvement Act of 1996 governs how the federal government collects money owed to itself. It is not a consumer protection statute, it does not regulate private collection agencies, and people who find it while researching a collection letter are usually looking for the Fair Debt Collection Practices Act instead. What the DCIA does is give federal agencies collection powers that private creditors do not have.

Wyoming gives creditors one of the longest collection windows in the country and gives debtors one of the most generous homestead protections. Those two facts define collection practice in the state, and both changed or matter more recently than most published guidance reflects.

An American Express collection lawsuit differs from the debt buyer cases that make up most consumer collection litigation, and the difference works against the standard playbook. Amex typically sues on accounts it still owns, which means the documentation problems that defeat debt buyers usually are not available. What is available is a set of contract provisions most cardmembers never read.
