In 2026, Colorado generally requires the court to set apart each spouse’s separate property and divide marital property in proportions the court deems just. That makes classification critical, because separate property is usually kept by the spouse who owns it, while marital property is divided. The difficult part is tracing, meaning you must show the source of funds and how an asset changed during the marriage, especially when accounts were commingled. Debts are analyzed similarly, and the court looks at what the debt was used for and when it was incurred. Good records like closing statements, account histories, and business ledgers can prevent disputes from becoming guesswork. A lawyer can help you build a tracing narrative and organize exhibits so the court can follow the money.
