Legal Question in Family Law in Colorado

Re: visitation rights

That really depends on what, if anything, has been done before. Generally speaking, you need to file a petition. If there are no prior court orders and you were not married to the mother, it would be a petition for allocation of parental responsibilities.

Please consult an attorney about your situation in a bit more detail first to be sure of the correct approach. It is impossible to be sure of whether this is what you need to do from your question.
