When you are navigating a custody case, one of your biggest concerns may be how much time you will spend with your child. You may wonder whether California requires parents to split parenting time equally or how a judge decides which schedule works best. You may also wonder if there is some kind of child custody percentage calculator that can help you develop a parenting plan.
At Barnholtz & Kugler, we understand how important these questions are. We can help you understand how to calculate a custody percentage in California, prepare for negotiations or trial, and make informed decisions about your child’s future.
What Are the Different Types of Child Custody in California?
California recognizes two main types of custody: legal custody and physical custody. Each can be joint or sole.
Legal Custody vs. Physical Custody
Legal custody determines who makes important decisions about your child’s education, healthcare, and welfare. And physical custody decides where the child will live and spend their time.
Joint Custody vs. Sole Custody
A court can decide that parents must share physical or legal custody (joint custody) or that one parent should be the only one with physical or legal custody (sole custody). Different combinations are possible.
Parents might share legal and physical custody. Alternatively, they might share legal custody while one parent has sole physical custody. A court can also award sole legal and physical custody to one parent or joint physical custody with sole legal custody, depending on the circumstances.
Under California law, joint custody may be presumed to serve the child’s best interests when both parents agree to it. However, joint custody does not automatically require a 50/50 schedule.
How Is Child Custody Determined in California?
Answering how California courts decide custody issues starts with the child’s best interests. California does not automatically favor mothers or fathers. Courts also cannot prefer one parent based on their:
- Sex,
- Gender identity,
- Gender expression, or
- Sexual orientation.
Instead, courts must make custody decisions based on what best serves the child’s health, safety, and welfare.
Parents can negotiate a parenting plan that establishes where their children will live and when they will spend time with each parent. When parents cannot agree, a judge may establish the custody arrangement after considering the family’s circumstances.
Child custody determinations involve much more than counting days or plugging information into a child custody time calculator. Courts consider whether a proposed arrangement provides a safe, stable, and supportive environment for the child.
What Factors Determine the Best Interests of the Child?
California’s Family Code identifies several important considerations when deciding what is in the best interests of a child, including:
- The child’s connection to their home, school, and community;
- Any history of abuse committed by either parent;
- The child’s health;
- The type of relationship the child has with each parent;
- The child’s needs;
- Whether either parent has issues with substance abuse; and
- The child’s wishes (when appropriate).
Courts may also consider practical circumstances, including school schedules, work schedules, transportation, where each parent lives, and each parent’s ability to meet the child’s daily needs.
How to Calculate Custody Percentage in California
A simple approach to calculating custody is to divide the time a child spends with one parent by the total time in an easy-to-measure period, such as a week or a month. Since child custody often dictates child support obligations, calculating time in two-week periods (which often align with pay periods) may also be helpful.
Consider the following formula: Parenting time percentage = (Parent’s parenting hours ÷ Total hours in a period) × 100. Then imagine your child spends 120 hours with you during a 336-hour, two-week period. Your calculation would be:
- 120 ÷ 336 × 100 = 35.7%
Under this calculation, the other parent’s share of custody would be approximately 64.3%.
You can also estimate parenting time using overnight stays. If your child spends 146 nights with you during a 365-night year:
- 146 ÷ 365 × 100 = 40%
However, counting overnights and counting actual hours can produce different results. These are scheduling estimates, not a universal, court-mandated formula.
Can a Child Custody Percentage Calculator Help?
A calculator can help you estimate how much parenting time each parent will receive and is a useful tool before negotiating a parenting plan, as it helps compare different schedules.
For example, consider the following schedules:
| Parenting schedule | Approximate time-share |
|---|---|
| Alternating full weeks | 50% / 50% |
| Alternating months | 50% / 50% |
| Four overnights every two weeks | 28.6% / 71.4% |
| Six overnights every two weeks | 42.9% / 57.1% |
These examples are not from an official child custody percentage calculator, and they are not the only way of determining how much time each parent will spend with their child. You and your attorney can customize your own formulas and spreadsheets to calculate custody based on your unique needs.
When calculating custody, remember that the numbers may not come out completely even. Your numbers may be uneven so that you can account for:
- Holidays,
- Summer vacations,
- School breaks, and
- Other schedule changes.
However, a child custody time calculator can be particularly useful when you want to understand how proposed changes may affect your overall parenting time.
How Can an Attorney Help?
Decisions regarding child custody are fact-intensive and should be tailored to each family’s specific needs. So, consulting an attorney who knows the legal standards and the judges in your jurisdiction can be vital to developing the best parenting plan for your family. An attorney can help:
- Evaluate your needs and your child’s needs,
- Prepare you for the court’s attitudes regarding certain parenting arrangements,
- Gather the strongest evidence to prove why your proposed parenting plan is the best,
- Negotiate favorable and enforceable terms in a parenting agreement,
- Argue for your position in court, and
- Protect your rights and your child’s best interests.
Making custody decisions can also be an emotionally charged process. Having an attorney by your side can provide you with peace of mind and support when you need it the most.
