Divorce Attorney in San Francisco

Certified Family Law Specialists. Super Lawyers Top 50 Women. Exclusively Family Law.

Divorce in California is called dissolution of marriage, and every case filed in San Francisco goes through the Unified Family Court at the Civic Center Courthouse. At Van Voorhis & Sosna LLP, we limit our practice exclusively to family law, and our attorneys handle dissolution cases in that court regularly. Founding partners Sarah Van Voorhis and Ariel Sosna were named to the Super Lawyers Top 50 Women list in July 2024, and the firm has Certified Family Law Specialists on staff recognized by the State of California. When your case is filed here, you want a team whose entire professional focus is San Francisco’s local rules, judicial expectations, and court procedures.

California is a no-fault divorce state: irreconcilable differences is the standard ground for dissolution, and neither spouse needs to prove wrongdoing. What makes cases complicated isn’t the grounds. It’s everything else. We represent traditional and non-traditional families, including LGBTQ dissolutions and domestic partnership dissolutions, and we offer a complimentary consultation so you can understand your options before committing to anything.

San Francisco Divorce Rules That Differ from Other California Counties

San Francisco has procedural requirements that don’t apply in every California county, and they can affect your timeline and strategy from the day you file.

Electronic Filing
The Unified Family Court requires e-filing for dissolution cases. Paper filings aren’t accepted; your documents need to meet the court’s formatting and submission standards before they can be processed.

Residency Requirements
To file in San Francisco, at least one spouse must have lived in California for six months and in San Francisco County for three months at the time of filing.

Mandatory Custody Mediation
If you and your spouse have minor children and can’t agree on a parenting plan, San Francisco Superior Court requires mediation through the Unified Family Court mediation program before a judge will hear the custody dispute. This isn’t optional, and being prepared for that process matters.

18-Month Status Hearing Rule
If a case isn’t resolved within 18 months of filing, San Francisco local rules require the court to schedule a mandatory status hearing. Staying on track with disclosures and negotiations isn’t just good practice here; it’s required.

Moore-Marsden Calculations & San Francisco Real Estate
San Francisco is one of the most expensive real estate markets in the country. When community funds were used to pay down the mortgage on a home one spouse owned before marriage, the Moore-Marsden calculation determines what share of any appreciation belongs to the community estate and what remains separate property. These calculations can involve significant dollar amounts in Bay Area cases and often require a financial analyst.

SB 1427 Joint Petitions (Effective January 1, 2026)
Under Senate Bill 1427, couples who agree on all divorce terms can file a single joint petition using Form FL-700, share one filing fee, and skip formal service entirely. The six-month waiting period begins from the joint filing date, and the process is simpler for fully agreeable couples.

Protecting Your Children During Divorce

When minor children are involved, custody and support decisions carry consequences that last well beyond the divorce itself. California courts evaluate custody based on the best interests of the child, weighing each parent’s ability to meet the child’s needs, time each parent has historically spent with the child, and geographic distance between the parents. Courts generally presume that frequent contact with both parents serves the child’s best interests, unless the facts indicate otherwise.

Our San Francisco divorce attorneys can assist you with:

• Child custody agreements
• Parenting plans
• Child support arrangements
• Co-parenting strategies
• Legal protections for your children

San Francisco Superior Court requires mediation for unresolved custody disputes before any judge will hear the matter. Our attorneys are familiar with that process and can help you prepare. Where the situation calls for it, our strategies may engage child psychology experts and family counselors to develop plans that reflect the children’s current and evolving needs.

Financial Planning & Divorce Settlements in the Bay Area

California is a community property state. Property acquired during the marriage is generally divided equally, while separate property acquired before marriage or through gift or inheritance is retained by the original owner. In San Francisco Bay Area divorces, the assets involved frequently go beyond real estate and savings accounts. Stock options, equity compensation, business goodwill, intellectual property, and retirement benefits are common, and most complex assets require a qualified appraiser to value properly.

Our attorneys provide guidance on property division, management of shared financial accounts, and spousal support calculations. Spousal support is determined by factors including length of marriage, the standard of living during the marriage, each spouse’s earning capacity, and the goal of allowing the recipient spouse to become self-supporting. We work closely with financial advisors, local tax advisors, and financial analysts to examine every financial dimension of a dissolution and craft settlements that account for both current and future economic conditions.

How to File for Divorce in San Francisco

The basic steps in a California dissolution follow a defined sequence. Preparation and accuracy at each stage reduce delays and avoid procedural setbacks at the Unified Family Court.

• Prepare the divorce documents and confirm they meet e-filing requirements
• File the initial petition with the Unified Family Court
• Serve the respondent spouse (or file jointly under SB 1427 if applicable)
• Exchange financial disclosures with the other party
• Negotiate agreements or attend hearings on contested issues
• Reach a final resolution and obtain a court judgment

We assist clients at every step, ensuring documentation is properly prepared and deadlines are met. Our firm has over 100 years of combined experience in family law, and we maintain close communication with clients about case status and legal expenses throughout.

Factors That Influence Divorce Costs in San Francisco

Dissolution costs can’t be predicted with precision, but these are the factors that drive them:

• The parties’ ability to agree on child custody
• Pension plan division between the parties
• Defining the nature of the contested issues
• The level of cooperation between lawyers and opposing parties
• The cost of expert witnesses and court reporters, if needed
• The hourly rate of your attorney
• Behavioral conduct of both spouses during proceedings

High-value assets common to Bay Area divorces, including stock compensation and San Francisco real estate, add complexity that increases costs. Our team provides a structured path to manage those expenses and is transparent about costs throughout.

What Our San Francisco Divorce Lawyers Handle

At Van Voorhis & Sosna LLP, our divorce attorneys handle the full range of matters that arise in dissolution cases, including:

• Child custody
• Child support
• Spousal support
• Distribution of property
• Marital estates
• Post-divorce disputes
• Modification of orders
• Appeals

In developing legal strategies, we are mindful of costs and aim to minimize expensive legal processes. We maintain close communication about legal expenses so clients are never surprised. Our familiarity with local judges and San Francisco’s procedural environment informs every strategy we develop.

When Does a Divorce Become Final in California?

The earliest a divorce can be finalized in California is six months after the petition is filed and the respondent is served. This mandatory waiting period applies regardless of how quickly both parties reach agreement. Under SB 1427, effective January 1, 2026, couples who file a joint petition begin the six-month period from the joint filing date. When there are disputes over child custody, property division, or spousal support, the timeline typically extends beyond six months. We take steps to meet timelines without sacrificing attention to your objectives.

Mediation & Collaborative Divorce in San Francisco

Resolving a dissolution outside of court typically means lower costs, faster resolution, and greater control over the outcome. Because the Unified Family Court requires mediation for unresolved custody disputes, most San Francisco parents will engage in some form of structured negotiation regardless of whether they expect to litigate. Being prepared for that process can be valuable.

Benefits of alternative dispute resolution include:

• Reduced stress and conflict
• More control over the outcome
• Confidentiality and privacy
• Cost savings compared to litigation
• Faster resolution in many cases

Our attorneys are trained in collaborative law and can guide you through mediation, collaborative divorce, or other alternative dispute resolution processes. Collaborative divorce requires both parties to negotiate with their attorneys present and a shared commitment to resolving issues without court intervention. We encourage settlements and don’t impede mutual agreements, but we are fully prepared to litigate when the situation calls for it.
