I was wondering how i go about getting a list of assets in order to start garnishment on an individual.

Although the particulars vary from state to state, there are procedures which can be employed to get discovery about a judgment debtor's assets.  For one thing (assuming that Colorado procedures are similar to those in the states in which I practice), you have the right to ask the judgment debtor to tell you about his/her/its assets under oath (i.e. under penalty of perjury), either by written questions (interrogatories) or by oral testimony (deposition).  If the judgment debtor doesn't comply with  your discovery demands, the Court will compel  him/her/it to respond under penalty of being found in contempt of court and fined or possibly imprisoned.
