What are the grounds for divorce in California?
California recognizes only two legal grounds for divorce under Family Code § 2310: (1) Irreconcilable Differences and (2) Permanent Legal Incapacity. California is a no-fault divorce state, meaning you do not have to prove wrongdoing, infidelity, or misconduct to end your marriage. If one spouse wants a divorce, the court will grant it, even if the other spouse objects.
For individuals filing in Santa Rosa or anywhere in Sonoma County, this means the focus of a divorce case is not on blame — it is on resolving property, child custody, and support issues under California law.
The Two Legal Grounds for Divorce in California
1. Irreconcilable Differences
This is the most common ground selected on Form FL-100 (Petition for Dissolution of Marriage). It simply means the marriage has broken down beyond repair. No evidence or testimony is required.
2. Permanent Legal Incapacity
This ground is rarely used and applies only in limited medical circumstances where a spouse is permanently unable to make decisions.
In most Santa Rosa divorce filings, “Irreconcilable Differences” is the selected basis.
The “Check-Box” Reality of No-Fault Divorce
California’s no-fault system simplifies the legal process. You do not need to:
- Prove adultery
- Prove abandonment
- Prove cruelty
- Provide witness testimony about misconduct
If properly filed and served, the divorce will proceed through the Sonoma County Superior Court regardless of whether both spouses agree.

When “Fault” Still Matters in a Santa Rosa Divorce
Although fault does not determine whether a divorce is granted, certain conduct can affect financial or custody outcomes.
Examples may include:
- Domestic violence, which can impact custody determinations
- Breach of fiduciary duty, such as hiding or wasting marital assets
- Financial misconduct affecting spousal support calculations
For example, spousal support awards depend on multiple statutory factors, not on moral blame. Learn more here: Spousal Support Attorney Santa Rosa.
Every case is fact-specific. Courts examine evidence carefully, and outcomes vary depending on circumstances.
The Mandatory Six-Month Waiting Period
Even in uncontested cases, California law requires a six-month waiting period before a divorce can be finalized (Family Code § 2339).
The clock starts when the responding spouse is formally served with divorce papers — not when the petition is filed.
This waiting period applies whether you file traditionally or use the updated joint filing option discussed here: The 2026 California Joint Petition.
Can My Spouse Refuse to Sign Divorce Papers?
No. A spouse cannot permanently block a divorce by refusing to sign documents. If properly served and deadlines pass without response, the court may proceed by default.
This protects individuals from being legally “trapped” in a marriage.
Are There Alternatives to Divorce?
Some couples consider legal separation instead of divorce. Legal separation addresses custody, support, and property division without formally ending the marriage.

Others pursue mediation to resolve disputes cooperatively before finalizing the divorce. Learn more here: The Role of Mediation in Santa Rosa Divorce Cases.
