Colorado does not limit the rights to children to only their biological parents, third parties and grandparents can also petition the Court for the allocation of parental responsibilities under certain conditions.
Grand Parent Standing
Grandparents may petition the court for the allocation of parental responsibilities, including visitation, when a custody determination has already been made or when the biological parent of the child is deceased.
If a grandparent does not qualify for standing as a grandparent, they may be eligible to petition the Court for the allocation of parental responsibilities as a third party.
Third Party Standing, also known as Psychological Parent Standing
When a person has acted as a parent and provided care to the child they may be able to petition the court for the allocation of parental responsibilities including visitation. The third party seeking visitation needs to have provided physical care for the child for a period of six months and they need to file the Petition with the Court within six months of losing physical care of the child.
In both grandparent and third party cases the Court will decide the visitation pursuant to the best interests of the child standard, the same standard applied in regular child custody cases.
