Grandparent rights can be somewhat tricky. Generally, parents have the right to parent as they see fit and grandparents cannot usually undermine or interfere. However, they can have limited visitation with grandchildren under Arizona law. Typically, grandparent visitation is much less than a parent would have and even as little as one day per month. The amount of time a grandparent receives is usually related to their involvement with the grandchildren prior to requesting court intervention.
