Nothing matters more than your relationship with your children. When parents separate, determining custody and visitation arrangements becomes one of the most emotionally charged aspects of family law. At By The Law Group APC, we understand the profound impact these decisions have on your family's future. Our experienced child custody attorneys advocate fiercely for your parental rights while always keeping your children's best interests at the forefront.

Best Interests of the Child Standard

Fam. Code §3011 California courts make all custody decisions based on the "best interests of the child" standard. This comprehensive analysis considers the child's health, safety, welfare, and the nature of their relationship with each parent.

Understanding Custody

Types of Custody in California

Legal Custody

Legal custody refers to the right and responsibility to make important decisions about your child's upbringing, including:

  • Education and school choice
  • Healthcare and medical decisions
  • Religious upbringing
  • Extracurricular activities
  • Travel and passport decisions

Joint Legal Custody: Both parents share decision-making authority. This is the default in California unless there's evidence that joint custody would harm the child.

Physical Custody

Physical custody determines where the child primarily lives and which parent provides day-to-day care:

  • Sole Physical Custody: Child resides primarily with one parent
  • Joint Physical Custody: Child spends significant time with both parents
  • Primary Physical Custody: One parent has majority time; other has visitation

Fam. Code §3020(b) California policy favors frequent and continuing contact with both parents, absent circumstances that would endanger the child's welfare.

Creating Arrangements

Parenting Plans & Visitation Schedules

A comprehensive parenting plan is essential for successful co-parenting. Whether you reach agreement through negotiation or the court orders a plan, it should address:

Regular Schedule

Weekday and weekend schedules, including pickup/drop-off times and locations.

Holiday Schedule

Alternating or dividing major holidays, school breaks, and special occasions.

Vacation Time

Extended summer vacation, school breaks, and provisions for travel with notice requirements.

Communication

Phone, video calls, and messaging between parent and child during non-custodial time.

Decision-Making

How parents will communicate and make decisions about the child's welfare.

Dispute Resolution

Procedures for resolving disagreements, such as mediation before returning to court.

Common Visitation Schedules
  • Alternating Weeks: One week with each parent
  • 2-2-3 Rotation: Two days, two days, alternating weekends
  • 2-2-5-5: Two days, two days, five days, five days
  • Every Other Weekend: One weekday evening plus alternating weekends
  • Bird's Nesting: Child stays in family home; parents rotate in and out
Best Interests Factors

What Courts Consider

Fam. Code §3011 California courts evaluate numerous factors when determining the child's best interests:

Child's Health & Safety

Any history of abuse, neglect, or substance abuse by either parent

Parental Relationship

Nature and quality of the child's relationship with each parent

Continuity & Stability

Maintaining consistency in home, school, and community

Parental Cooperation

Ability of parents to co-parent and encourage child's relationship with other parent

Child's Preference

If of sufficient age and capacity, the child's wishes may be considered

Parental Fitness

Mental and physical health of each parent

Siblings

Desirability of keeping siblings together

Domestic Violence

Fam. Code §3044 Creates presumption against custody for perpetrators

Special Situations

Complex Custody Matters

Fam. Code §7501 When a custodial parent wishes to relocate with the child, complex legal issues arise. The court must balance the parent's right to travel against the child's need for stability and relationship with the other parent.

Factors considered:

  • Reason for the move (job, family support, new marriage)
  • Distance of the proposed move
  • Child's age and relationship with each parent
  • Impact on visitation with non-moving parent
  • Child's ties to current community

Important: If you have sole physical custody, you generally have a presumptive right to relocate. With joint custody, the court will re-evaluate the custody arrangement based on the child's best interests.

Custody orders can be modified when there has been a "significant change of circumstances" affecting the child's welfare. Common reasons include:

  • Relocation of a parent
  • Changes in parent's work schedule or availability
  • Evidence of substance abuse or domestic violence
  • Child's changing needs as they age
  • Parent's failure to follow existing orders
  • Improvement in circumstances (for parents seeking increased time)

Fam. Code §3042 The court may consider the wishes of a child who is of sufficient age and capacity to reason.

Fam. Code §3100-3105 Grandparents may petition for visitation under certain circumstances, particularly when a parent is deceased or the parents are separated. However, the U.S. Supreme Court in Troxel v. Granville established that parents have a fundamental right to make decisions about their children's upbringing.

Grandparents must demonstrate that visitation is in the child's best interests and that a substantial pre-existing relationship exists.

Evidence Code §730 In contested cases, the court may appoint a custody evaluator (psychologist, psychiatrist, or social worker) to investigate and make recommendations.

The evaluation typically includes:

  • Interviews with both parents and the child
  • Home visits
  • Review of relevant documents
  • Psychological testing (if appropriate)
  • Interviews with collateral contacts (teachers, therapists)

While not binding, courts give significant weight to evaluator recommendations.
