Paternity and Parental Rights in California
For unmarried parents in California, establishing legal parentage is the first step in securing custody and parenting time rights. Parentage can be established by signing a Voluntary Declaration of Parentage (VDOP) or through a court process that may include genetic testing.
​
Until legal parentage is established, the mother has sole legal and physical custody by default. Once parentage is confirmed, the court can issue orders for legal custody, physical custody, parenting time, and child support, allowing both parents to participate fully in the child’s life.
Best Interest of the Child Standard
California courts make all custody and parenting time decisions based on the best interest of the child standard. This standard requires judges to evaluate what arrangement will best support the child’s health, safety, welfare, and long-term well-being. There is no automatic preference for either parent, and courts do not assume children should live primarily with one parent based on gender or past roles.
California Family Code §3011 outlines the core factors courts must consider. Judges evaluate the specific circumstances of each family to determine which arrangement provides the most stable, supportive environment for the child.
​
Courts commonly review:
​
-
The health, safety, and welfare of the child
-
Any history of abuse, including domestic violence or child abuse
-
Each parent’s ability to meet the child’s daily needs
-
The nature and quality of each parent’s relationship with the child
-
The amount of contact each parent has had with the child
-
Each parent’s willingness to support the child’s relationship with the other parent (unless safety issues exist)
-
Stability of each home, including routines, school continuity, and environment
-
Any history of substance abuse or unsafe behavior
-
The child’s wishes, when the child is of sufficient age and maturity (typically age 14+, though younger children may be heard)
​
No single factor determines the outcome. Instead, judges weigh all relevant circumstances to create an arrangement that promotes the child’s long-term stability, emotional well-being, and strong, healthy relationships with both parents whenever safe and appropriate.
Physical Custody and Parenting Time (Visitation)
California divides custody into two parts: legal custody (decision-making authority) and physical custody (where the child lives). Physical custody may be joint, where the child spends significant time with both parents, or sole, where the child primarily lives with one parent and has scheduled time with the other. Parenting time—often called visitation in California—is structured to support the child’s routine, development, and relationship with both parents.
​
Parenting time schedules vary widely based on the child’s age, parental involvement, distance between homes, school commitments, and each family’s circumstances.
Schedules may include:
​
-
Alternating weekends
-
Midweek visits or overnights
-
Shared week-on/week-off arrangements
-
2-2-3 or 3-4-4-3 rotations
-
Holiday and school break schedules
-
Extended summer time
​
California courts aim to create parenting time arrangements that provide stability, minimize conflict, and allow the child frequent and continuing contact with both parents. Judges look for schedules that meet the child’s developmental needs and support a strong parent-child relationship in each home. When parents cannot agree on a schedule, the court will order one based on the child’s best interests and the family’s unique situation.
Legal Custody (Decision Making)
California divides custody into two parts: physical custody (where the child lives) and legal custody (who makes major decisions about the child’s upbringing). Legal custody may be joint, where both parents share decision-making authority, or sole, where one parent has the final responsibility for major decisions.
Legal custody includes important choices about:
​
-
Education and school enrollment
-
Medical, dental, and mental health care
-
Therapy and counseling
-
Religious or cultural involvement
-
Extracurricular activities and long-term planning
​
In most cases, California courts prefer joint legal custody, even when physical custody is not equal, unless there are safety concerns, high conflict, or a history of domestic violence.
​
When determining legal custody, California judges consider:
​
-
Each parent’s ability to communicate and cooperate
-
Past involvement in major decisions
-
The child’s medical, educational, and emotional needs
-
Any history of abuse, coercive control, or substance misuse
-
Each parent’s willingness to support the child’s relationship with the other parent
​
California law emphasizes that legal custody arrangements should support the child’s wellbeing, minimize conflict, and allow important decisions to be made in a consistent and child-focused way.
Court Expectations & Co-Parenting Responsibilities
California courts expect parents to communicate respectfully, follow court orders, and work together to meet their child’s daily and long-term needs. Judges look closely at how each parent supports stability, reduces conflict, and encourages a healthy relationship between the child and the other parent. These expectations apply whether parents share custody equally or one parent has primary responsibility.
​
Courts typically expect parents to:
​
-
Share important information about the child in a timely and accurate manner
-
Communicate calmly, respectfully, and in a child-focused way
-
Follow the parenting schedule and arrive on time for transitions
-
Support routines that help the child feel secure in both homes
-
Encourage the child’s relationship with the other parent when safe
-
Avoid negative comments or conflict in front of the child
-
Use agreed-upon communication tools (text, email, parenting apps)
-
Work toward resolving disagreements before returning to court
​
Judges do not expect parents to always get along, but they do expect cooperation that protects the child from conflict. Parents who demonstrate reliability, respect, and consistent involvement are more likely to be viewed favorably in California custody decisions.
Parenting Plans
A parenting plan—called a “custody and visitation order” in California—describes how parents will share time, responsibilities, and important decisions after separation. Parenting plans can be created jointly by the parents or ordered by the court when parents cannot agree. The focus is always on the child’s best interests, stability, and long-term wellbeing.
​
A complete parenting plan typically includes:
​
-
A weekly parenting-time schedule
-
Holiday and vacation arrangements
-
Summer break schedules
-
Transportation, pickups, and drop-offs
-
How parents will share major decisions (legal custody)
-
Communication expectations between parents
-
How changes or disagreements will be handled
​
California courts prefer parenting plans that support predictable routines, minimize conflict, and give the child meaningful time with both parents whenever possible. When parents do not reach an agreement, the court will create a plan based on the child’s developmental needs, safety, and the unique circumstances of the family.
Creating a Parenting Plan
Parents can create their own parenting plan in California if they are able to communicate safely and cooperatively. A well-written plan helps prevent conflict, provides predictable routines for the child, and shows the court that both parents can work together in the child’s best interest. When parents submit a complete and reasonable plan, judges are likely to approve it.
​
When creating a parenting plan, parents should consider:
​
-
The child’s age, developmental stage, and daily routine
-
Each parent’s work schedule and availability
-
Transportation, distance between homes, and school location
-
How holidays, school breaks, and vacations will be divided
-
How major decisions will be made (legal custody)
-
How information about the child will be shared
-
How disagreements or changes will be handled
​
The most effective plans are specific, realistic, and focused on the child’s needs—not parental preferences. Parents who create a balanced plan that provides stability and meaningful time with both parents often have smoother co-parenting experiences and fewer future conflicts.
Modifying a Parenting Plan
Parenting plans may need to be updated as a child grows or as family circumstances change. In California, parents can modify a custody or visitation order when they both agree to the change, or when one parent can show that there has been a “significant change in circumstances” that affects the child’s wellbeing. The court’s focus remains on what is best for the child, not on convenience for either parent.
Common reasons parents request a modification include:
-
Changes in work schedules or availability
-
A child’s increased school, medical, or activity needs
-
Safety concerns or changes in a parent’s stability
-
Relocation or increased distance between homes
-
A pattern of missed visits or inconsistent involvement
-
Developmental changes as children age
​
If both parents agree, they can submit a written modification for the court to approve. If they do not agree, a judge will review evidence and determine whether the change supports the child’s best interests. Courts prefer modifications that improve stability, reduce conflict, and meet the child’s current needs.
Notes for Mothers
California courts expect both parents to support the child’s relationship with the other parent. Mothers are encouraged to provide clear communication, follow the parenting schedule, and help maintain consistency between homes. Judges focus on stability, cooperation, and each parent’s ability to meet the child’s needs without exposing the child to conflict.
​
Helpful things for mothers to keep in mind include:
​
-
Supporting the child’s relationship with the father when it is safe
-
Communicating respectfully and sharing important information promptly
-
Encouraging predictable routines in both households
-
Following court orders and keeping transitions low-stress
-
Avoiding negative comments about the other parent in front of the child
-
Using agreed-upon communication tools or apps when required
-
Being consistent about school attendance, appointments, and activities
​
Courts do not expect perfection. They expect parents to be reliable, cooperative, and child-focused. Mothers who demonstrate stability, transparency, and support for the child’s relationship with both parents strengthen their position in custody discussions.
Notes for Fathers
California courts evaluate both parents using the same standards: stability, cooperation, communication, and support for the child’s relationship with the other parent. Fathers are encouraged to stay actively involved, communicate clearly, and demonstrate consistency in caregiving. Judges appreciate parents who remain child-focused and avoid unnecessary conflict.
​
Helpful things for fathers to keep in mind include:
​
-
Staying engaged in the child’s daily life, schoolwork, and appointments
-
Communicating respectfully and sharing important information promptly
-
Supporting routines that help the child feel secure
-
Using agreed-upon communication tools when required
-
Being reliable with pickups, drop-offs, and scheduled parenting time
-
Keeping records of involvement (school activities, medical visits, etc.)
-
Avoiding arguments or negative comments about the other parent in front of the child
​
Courts look for fathers who show consistency, emotional availability, and a commitment to maintaining a low-conflict environment for the child. Demonstrating steady involvement and a cooperative attitude strengthens a father’s position in custody matters.
Breastfeeding Considerations
Breastfeeding can influence parenting-time decisions for infants, especially when very young babies rely heavily on frequent feedings. California courts consider breastfeeding as one factor among many, while still aiming to support meaningful bonding and parenting time for both parents. Judges prefer solutions that balance the child’s nutritional needs with the importance of both parent–child relationships.
​
Factors courts may consider include:
​
-
The child’s age and feeding schedule
-
Whether the baby can take expressed milk or formula
-
Each parent’s ability to support consistent feeding routines
-
The distance between parents’ homes and feasibility of short visits
-
Whether overnights are appropriate based on the child's developmental stage
-
The parents’ level of cooperation and ability to adjust schedules
​
Breastfeeding does not automatically prevent a baby from spending meaningful time with the non-breastfeeding parent. California courts encourage flexible arrangements—such as shorter, more frequent visits or gradual increases in time—to meet the child’s needs while supporting both parent-child bonds.
California Family Law and Statutes
California’s custody and parenting laws are found in the California Family Code, which outlines how courts make decisions about legal custody, physical custody, visitation, and the best interests of the child. These statutes guide judges, mediators, and attorneys in resolving parenting disputes and help parents understand how decisions are made.
​
Key California Family Code sections related to custody include:
​
-
§3020 – Public Policy Favoring Frequent and Continuing Contact
-
§3010 – Rights of Each Parent
-
§3083 – Joint Legal and Physical Custody Definitions
-
§3022 – Court’s Authority to Modify Custody Orders
-
§3015 – General Custody Provisions
​
Parents may also use California’s official family law resources when preparing for court or mediation:
-
Local county family court websites
-
California Judicial Council forms (custody, visitation, mediation requests)
-
State resources offering mediation, parenting classes, and supervised visitation listings
​
Understanding these statutes helps parents navigate the custody process with clarity and confidence. When both parents know what the law requires and expects, they can make more informed decisions and create parenting plans that better support their child’s emotional and developmental needs.
