State Laws for Co-Parenting
Last reviewed: July 2026.
Everyone has their unique parenting path, but many legal matters vary based on state. Whichever your arrangement is, it’s important to decide on an agreement that obliges with your state laws and we recommend you consult with a family attorney in your jurisdiction.
What is Co-Parenting?
Co-parenting occurs when two unmarried legal guardians of a child share responsibility for raising a child. The two parents communicate frequently and work together to raise the child in a healthy environment. Co-parenting can result from divorced parents or individuals who dated or chose to raise a child in a platonic relationship.
While parenting and co-parenting may sound similar, they are quite different. When individuals choose to co-parent, they need to design an effective plan to address health-care issues, transportation, morals, and more. For a good co-parenting relationship to work, both partners must be fully committed to raising the child. This relationship is not the best situation for everyone. However, it can positively impact the child.
Supportive vs. Non-Supportive Co-Parenting
Deciding to co-parent is an ongoing process that continuously needs work. Parents that practice a supportive relationship help the child grow into a healthy individual.
Supportive
A supportive co-parenting relationship includes respect, forgiveness, and the ability to listen to each other. If both parents emit the same message, the child’s well-being benefits. A child will be able to handle difficult situations if both parents are working together. Here are some major points to include a supportive co-parenting relationship.
- Both parents do what is in the best interest of the child when handling decisions.
- Parents respect the other parent’s right to participate in parenting.
- Parents agree on some basic rules for raising their children.
- Let go of angry feelings and resentment.
- The parenting environment is warm and loving.
Non-Supportive
A non-supportive relationship happens when parents don’t work together for parenting concerns. With this type of parenting, the child could feel guilty, stressed, anxious, and unsure of where to turn to between parents. Make sure to be wary of topics that include money, religion, politics, discipline, education, or medical services.
Co-Parenting Benefits
A supportive co-parenting relationship helps children by showing the child they have a home with both parents and reassures them that both parents want the best for them. It allows children to develop multiple meaningful relationships and communication skills. It can double the number of feelings of support and love as well.
Co-Parenting State Laws
Custody and parental-responsibility rules are set at the state level in the United States, and they vary by state and change over time. As a general matter, courts decide custody based on the best interests of the child, but the specific factors, terminology (some states use “parental responsibilities” rather than “custody”), and the weight given to a child’s wishes differ from state to state. Because these rules vary by state and change frequently, check your state’s current statutes and consult a family-law attorney in your jurisdiction before making decisions.
Child custody arrangements are not easy and can vary based on the state you live in. If both the co-parents live in different states, that should also be factored into making an arrangement.

Because laws governing parentage and custody differ by state, working with a family law attorney in your jurisdiction is recommended.
