What Are the Grounds for Divorce in California?

Divorce proceedings can be complicated, and understanding the legal grounds for divorce in your state is a first step. California's approach to divorce is notably different from many other states, as it operates under a "no-fault" divorce system. This approach means that unlike jurisdictions requiring proof of fault (such as adultery or abandonment), California does not require one spouse to prove the other was responsible for the marriage's breakdown.

If you are planning to get a divorce in California, you should call a family law firm to ensure your rights and future are protected.

Grounds for Divorce in California

In California, the legal framework for divorce primarily operates under a "no-fault" system. The no-fault law significantly streamlines the process compared to states that require proof of marital misconduct.

Irreconcilable Differences

The most common and almost exclusive ground for divorce in California is "irreconcilable differences." This term means that the marriage has deteriorated to a point where there's no realistic possibility of the couple getting back together.

Under this system, neither spouse must present evidence of the other's wrongdoing or specific reasons for the marriage's breakdown. Suppose one party states irreconcilable differences exist under oath, and the judge accepts this testimony. In that case, the court can grant the divorce.

Incurable Insanity

A rarely used secondary ground for divorce is "incurable insanity." For the court to grant a divorce on this basis, the petitioner must demonstrate, with substantial medical documentation and expert testimony, that their spouse was incurably insane during the marriage.

This evidence proves that the insanity is permanent and renders the spouse unable to manage their care or property. Due to the high burden of proof and the ethical considerations involved, this ground is infrequently pursued.

Amicable Divorces

California's no-fault divorce system inherently promotes a more amicable approach to dissolving a marriage. By removing the need to assign blame, the system encourages couples to focus on practical matters rather than contentious accusations.

When a divorce is amicable, both parties generally agree on the terms of their separation. This form of negotiation can lead to a more cooperative process, often involving:

  • Mediation: Couples may work with a neutral third-party mediator to facilitate discussions and reach mutually agreeable solutions on issues such as property division, child custody, and support.
  • Collaborative Divorce: This process involves spouses and their respective attorneys agreeing to resolve issues outside of court through meetings and negotiations, focusing on cooperative problem-solving.
  • Stipulated Judgments: When spouses agree on all terms, they can present a "stipulated judgment" to the court, outlining their agreements on asset and debt division, parenting plans, and support. Doing so allows the court to formalize their agreement without needing a trial.


Even in amicable divorces, legal complexities can arise, particularly concerning the division of community property and debts, child custody and visitation arrangements, and spousal or child support orders.

Therefore, consulting with a qualified family law attorney is recommended to ensure all legal requirements are met and that both parties' rights and interests are protected throughout the process.

The goal of an amicable divorce is to dissolve the marriage efficiently and respectfully, minimizing conflict and focusing on a constructive path forward for all involved, especially if children are part of the family.

Steps for Getting a Divorce in California

  • Filing a Petition for Divorce: The petitioner begins the process by filing Form FL-100 with the superior court in the county where they or their spouse have lived for at least six months and in the county of filing for a minimum of three months.
  • Serving the Papers: The petitioner must legally "serve" the respondent spouse with a copy of the filed petition with Form FL-110, also called a summons. This officially notifies the respondent of the divorce filing and that they can respond.
  • Respondent's Reply: The respondent has 30 days from the date they are served to file a Form FL-120. This is a response filed with the court. If they do not respond, the petitioner can go forward with a default divorce.
  • Financial Disclosures: Both parties are required to exchange preliminary declarations of disclosure, which include detailed information about their income, expenses, assets, and debts. This ensures transparency, helps facilitate equitable division of property, and supports discussions.
  • Negotiation and Agreement (or Litigation):
  • Amicable Resolution: If the divorce is amicable, as mentioned, couples can pursue mediation, collaborative divorce, or direct negotiation to reach agreements on the dividing assets, setting up custody arrangements, visitation, and spousal or child support. These agreements are then formalized into a "Stipulated Judgment."
  • Litigation: If parties cannot agree, the case may proceed to contested hearings or a trial, where a judge will decide on unresolved issues.


It is highly recommended that you consult with a qualified family law attorney throughout this process to ensure that you meet all legal requirements and protect your rights and interests.

Summary of Grounds for Divorce

It is important to note that while the grounds for divorce are straightforward in California, the process can still involve detailed legal matters. These matters include dividing community property and debts, child custody, visitation schedules, and spousal/child support orders. Consulting with a qualified family law attorney is highly recommended to understand these details and protect your rights and interests throughout the divorce process.

Frequently Asked Questions

How long does it take to complete a divorce in California?

The duration of a divorce in California varies based on whether a dissolution of marriage is contested or uncontested. An divorce that's uncontested happens when both parties agree on terms. This amicable form of divorce takes at least six months due to a mandatory waiting period. On the other hand, a contested divorce may last months or years, depending on the case.

Both spouses have equal ownership of these items, and upon divorce, community property is generally divided 50/50. This includes real estate, bank accounts, retirement funds, and debts incurred during the marriage.

During divorce proceedings in California, both spouses have the right to be notified of the proceedings and to respond. They are entitled to full financial disclosure from each other and can seek legal representation.
