If you live in Sunnyvale and are searching for a divorce lawyer, the first practical fact to know is that your case does not get handled at the Sunnyvale Courthouse on West El Camino Real. That branch does not process family law matters. Divorce, custody, and support cases for every Sunnyvale neighborhood, from Lakewood and Ponderosa to Birdland and the Murphy Avenue downtown core, are filed and heard at the Santa Clara County Family Justice Center Courthouse in San Jose. This page explains where to file, what it costs, how long it takes, and the California statutes that control the outcome, written for someone who actually lives here.

How do I file for divorce in Sunnyvale, California?
To file for divorce in Sunnyvale you complete a Petition (Form FL-100) and Summons (Form FL-110), then file them at the Santa Clara County Family Justice Center Courthouse at 201 North First Street, San Jose, with the $435 filing fee. If you have minor children, you also file the UCCJEA Declaration (Form FL-105). After filing, you must serve your spouse, who then has 30 days to respond.
The steps are sequential. You prepare the petition listing your date of marriage, date of separation, and requests for property, support, and custody. You file in person at the San Jose courthouse, by mail, or through the court's e-filing portal. The clerk stamps your case number and you arrange service by a third party, never by yourself. New for 2026 under Senate Bill 1427, spouses who agree on every term can file a single Joint Petition using Form FL-700, which lets one $435 fee cover both parties instead of the old $870 combined cost. Sunnyvale residents who want help completing forms can use the court's Self-Help Center and Family Law Facilitator's Office, which serves all Santa Clara County filers.

Where do I file for divorce in Sunnyvale? (which courthouse)
Sunnyvale residents file for divorce at the Family Justice Center Courthouse, 201 North First Street, San Jose, CA 95113, roughly 8 to 10 miles southeast of downtown Sunnyvale. This is the single family law hub for all of Santa Clara County. The Sunnyvale Courthouse at 605 West El Camino Real, while physically in the city, does not accept divorce, custody, or support filings.
Venue follows residency, not city limits. Because Sunnyvale sits inside Santa Clara County, your case is governed by the county Superior Court and the Santa Clara County Local Family Rules in addition to the statewide California Family Code. Plan your trip accordingly: the Family Justice Center is near the San Jose civic center off North First Street, accessible from Highway 87 and reachable by VTA light rail. Filers from Sunnyvale, Mountain View, Santa Clara, and Cupertino all use this same location, so the clerk's office can be busy. Bring two copies of every form plus the original, since the clerk keeps the original and returns conformed copies for your records and for service.
How much does a divorce lawyer cost in Sunnyvale?
A divorce lawyer in Sunnyvale typically charges $350 to $600 per hour, with most attorneys requiring a retainer of $5,000 to $15,000 up front. An uncontested divorce handled with limited attorney involvement may total $3,500 to $7,000, while a contested case with custody and property disputes commonly runs $20,000 to $50,000 or more, reflecting Silicon Valley's higher billing rates.
Several local factors push costs in the Sunnyvale and broader South Bay market above the California average. Tech-sector compensation means cases often involve restricted stock units, vested and unvested options, and complex retirement accounts that require a forensic accountant or a Qualified Domestic Relations Order, each adding fees. The $435 court filing fee is separate from attorney charges and is waivable through Form FW-001 if your income qualifies. Many Sunnyvale couples reduce cost through mediation or a limited-scope arrangement where the attorney handles only the contested issues. Estimate your own exposure with the divorce cost estimator before retaining counsel.
How long does a divorce take in Sunnyvale?
A divorce in Sunnyvale cannot finalize sooner than six months and one day from the date your spouse is served, under California Family Code § 2339. That six-month clock is a minimum, not an average. Uncontested cases at the Santa Clara County Family Justice Center typically conclude in 6 to 9 months, while contested cases involving custody or asset disputes average 12 to 18 months.
The waiting period starts on the date of service or the respondent's first appearance, whichever comes first, not on the date you file. It cannot be shortened or waived for any reason, even when both spouses fully agree. During those six months the case can still move forward: you exchange Preliminary Declarations of Disclosure (Forms FL-140 and FL-142), negotiate a Marital Settlement Agreement, and resolve temporary support. Santa Clara County's caseload and any required hearings on custody or support can extend the timeline. Map your stages with the divorce timeline tool or the California divorce timeline guide.
What are the residency requirements to file in Santa Clara County?
To file for divorce in Santa Clara County, at least one spouse must have lived in California for six months and in Santa Clara County for three months immediately before filing, under California Family Code § 2320. Only one spouse needs to meet this two-part test. If you have lived in Sunnyvale for at least three months and in California for six, you qualify to file at the San Jose courthouse.
Residency means actual domicile, an intent to remain, not a temporary stay. If you recently moved to Sunnyvale and do not yet meet the three-month county requirement, you may file for legal separation first, which carries no minimum residency period, then amend the petition to a dissolution once you qualify. A residency defect can be waived if your spouse does not raise it within the 30-day response window. Registered domestic partnerships have no residency requirement at all.
How is property divided in a Sunnyvale divorce?
California is a community property state, so the Santa Clara County court divides all community assets and debts equally, a 50/50 split, under California Family Code § 2550. Property acquired during the marriage is community property; property acquired before marriage, after the date of separation, or by gift or inheritance is separate property and stays with the owning spouse.
This matters in Sunnyvale because Silicon Valley estates often include high-value assets: a marital home in a market where median values exceed $1.5 million, tech equity compensation, and retirement plans. Stock options and RSUs are characterized using time-rule formulas based on grant and vesting dates relative to the separation date, which is why the separation date is frequently contested. The court must divide the net community estate equally, distributing assets and obligations so each spouse's residual share is equal. Spouses can override the equal-division default by written agreement. Estimate division scenarios with the property division tool and run support numbers using the alimony estimator.
How is child custody decided in Sunnyvale?
Custody in a Sunnyvale divorce is decided by the best interest of the child standard under California Family Code § 3011 and § 3020. The Santa Clara County court weighs the child's health, safety, and welfare, any history of abuse, and the nature of each parent's contact with the child. State policy under § 3020 favors frequent and continuing contact with both parents unless that contact would harm the child.
California uses two categories: legal custody, the right to make major decisions, and physical custody, where the child lives. Both can be joint or sole. Contested custody cases in Santa Clara County are usually routed through Family Court Services for mediation before a judge rules. When safety and the contact policy conflict, § 3020 requires the court to prioritize the child's safety. Calculate guideline support with the child support calculator.
