10 Best Family Law Attorneys in Costa Mesa, CA (2026)

This guide covers 10 family law firms serving Costa Mesa, California, drawn from firms with offices in Costa Mesa itself or in neighboring Newport Beach, all of which file their cases in the Orange County Superior Court family law system. Each firm was evaluated on three things: the credentials of its lead attorneys (including certification as a Family Law Specialist by the State Bar of California Board of Legal Specialization), the depth of its experience with divorce, custody, support, and property division in Orange County, and whether family law is the firm’s dedicated focus or one practice among several.

When comparing options, ask three practical questions. Does the attorney regularly appear in Orange County family court and know how custody mediation and Family Court Services work locally? Will you work directly with the attorney you hire, or will an associate handle most of the case? And does the firm have the financial and litigation depth your situation needs, such as business valuation for a company owner or appellate experience if a ruling may need to be challenged? The list below is not ranked and is not sponsored. Firm details come from each firm’s own website, State Bar of California records, and attorney directories including Avvo, Super Lawyers, Martindale-Hubbell, and The Best Lawyers in America; where a specific rating is cited, the source is named in the entry.

1. Engels O’Brien

• Attorney/Key Figure: Christopher Engels, Attorney (family law); Sarah K. O’Brien, Attorney (litigation)
• Headquarters: 2900 Bristol Street, Suite G205, Costa Mesa, CA 92626
• Phone: (949) 269-7709
• Website: engels-obrien.com
• Practice Areas: Family Law (Divorce, Child Custody & Visitation, Child Support, Domestic Violence, Paternity, Prenuptial Agreements, Same-Sex Divorce); Business Law and Civil Litigation; Construction Law; Employment and Wage & Hour Law; Wills, Trusts & Estate Planning
• Firm Size: Boutique (2 attorneys); serves the Los Angeles-Orange County and Seattle-Bellevue-Tacoma areas
• Practice Area Page: Costa Mesa Family Lawyer
• Social Profiles: Facebook, LinkedIn, Super Lawyers, Martindale

Engels O’Brien is a Costa Mesa firm whose family law practice is led by Christopher Engels, who was named a 2022 Rising Star by Super Lawyers. Engels has completed minor’s counsel training, the program that prepares attorneys to represent children’s interests in custody proceedings, and he builds his custody work around keeping children’s needs at the center of the case. His practice covers both sides of the family law spectrum: negotiating separation and settlement agreements to reach an uncontested divorce efficiently, and litigating contested divorces, marital property disputes, and custody battles when an agreement is not possible.

What sets the firm apart is direct access. Clients work with their attorney throughout the matter rather than being passed to associates or support staff, and the firm puts a stated emphasis on keeping costs down in a process that can quickly become expensive. Partner Sarah K. O’Brien adds more than 11 years of litigation experience, including appellate work that has reached the California Supreme Court and admission to all four U.S. District Courts in California, which gives the firm strong briefing and motion capability when a family case turns on the written record. Because the firm also handles business, construction, and estate planning matters, clients whose divorce involves a family business or trust issues can keep related work under one roof.

2. Farzad & Ochoa Family Law Attorneys, LLP

• Attorney/Key Figure: B. Robert Farzad, Managing Partner; Yvette Ochoa, Partner
• Headquarters: 611 Anton Blvd., Suite 840, Costa Mesa, CA 92626 (additional offices in Los Angeles and San Diego)
• Phone: (714) 937-1193
• Website: farzadlaw.com
• Practice Areas: Divorce (Contested, High Conflict, Amicable), Child Custody, Child Support, Alimony, Asset Division, Attorney’s Fees, Domestic Violence
• Firm Size: Mid-size family-law-only firm with three Southern California offices
• Practice Area Page: Costa Mesa Office
• Social Profiles: Facebook, YouTube, LinkedIn, Avvo

B. Robert Farzad has been licensed in California since 1996 and practices from the firm’s Costa Mesa office in Pacific Arts Plaza, across from South Coast Plaza. Before forming Farzad & Ochoa with Yvette Ochoa in 2019, he served as an associate and managing litigation attorney at Wallin & Klarich. He has presented Continuing Education of the Bar’s Key Developments in Family Law program, has been recognized by The Best Lawyers in America since 2025, and holds a 10.0 Avvo rating with a 5.0 average across 19 client reviews.

The firm handles only family law, and only in Southern California courts, which shows in its unusually deep library of published guides on topics such as 730 custody evaluations, Family Code 2030 fee requests, and Epstein credits. One trade-off worth knowing: the firm’s first meeting is a paid strategy session rather than a free consultation, which suits clients who want substantive advice up front but adds a cost before you commit.

3. Sarieh Family Law

• Attorney/Key Figure: Wail Sarieh, Founder and Certified Family Law Specialist
• Headquarters: 3200 Park Center Drive, Suite 200, Costa Mesa, CA 92626
• Phone: (714) 542-6200
• Practice Areas: Divorce, Child Custody & Visitation, Move-Away Cases, Paternity, Child & Spousal Support, Guardianship, Domestic Violence
• Firm Size: Boutique, family law only
• Social Profiles: Avvo

Wail Sarieh began practicing family law in 2005 and earned certification as a Family Law Specialist from the California Board of Legal Specialization in 2012, dedicating his entire practice to family law. In November 2025 the firm moved its Orange County office from Santa Ana to Costa Mesa, putting it a short drive from the Lamoreaux Justice Center where county family cases are filed.

The firm’s Avvo profile lists divorce, custody, move-away, and paternity matters as its core work, with a 4.6 average across 53 client reviews and repeated praise from fathers in custody disputes. The trade-off is the flip side of a founder-led boutique: the certified specialist credential sits with one lead attorney, so clients should confirm how much of their case he will handle personally.

4. Minyard Morris, LLP

• Attorney/Key Figure: Mark E. Minyard, Founding and Managing Partner
• Headquarters: 1811 Quail Street, Newport Beach, CA 92660
• Phone: (949) 724-1111
• Website: minyardmorris.com
• Practice Areas: Divorce, High Net Worth and Business Owner Divorce, Child Custody and Parenting Plans, Spousal and Child Support, Property Division, Domestic Violence, Paternity, Mediation
• Firm Size: Large (about 20 attorneys); practice limited to Orange County family law since the 1970s

Minyard Morris limits its entire practice to family law matters filed in Orange County, a focus it has kept for more than four decades. Managing partner Mark E. Minyard is a Certified Family Law Specialist who generally concentrates on complex, high-net-worth cases involving business interests, and he has been named to the Lawdragon 500 Leading Family Lawyers list. Partner Michael A. Morris, also a certified specialist, was named Best Lawyers’ Orange County Family Law “Lawyer of the Year” in 2013, 2018, and 2025.

The firm’s size gives it a bench of certified specialists who can staff complex financial cases, and it is known in the local bar for a policy of discretion and civility rather than scorched-earth litigation. The trade-off of a 20-lawyer firm is that day-to-day work may be spread across a team, so it is worth asking which attorney will be your primary point of contact.

5. Holstrom, Block & Parke, APLC

• Attorney/Key Figure: Dayn A. Holstrom, Owner and Managing Partner
• Headquarters: 4940 Campus Drive, Suite A, Newport Beach, CA 92660 (additional offices in Corona, Riverside, Temecula, San Diego, and Vista)
• Phone: (888) 998-3045
• Website: hbplaw.com
• Practice Areas: Family Law (Divorce, Child Custody, Child & Spousal Support, Domestic Violence, Collaborative Divorce, Post-Decree Modifications and Enforcement), Appeals, Estate Planning, Probate
• Firm Size: Mid-size regional firm with multiple Certified Family Law Specialists
• Social Profiles: Martindale, Avvo

Dayn A. Holstrom is a Certified Family Law Specialist who has practiced for more than three decades and previously taught at Western State University College of Law. His partners include Carrie Block, also a certified specialist and trial attorney, and James Parke, a certified specialist who previously practiced at Minyard Morris and has been selected to Super Lawyers every year since 2004.

The firm describes itself as focused on high-asset and highly complex cases, and its appellate and collaborative divorce capabilities give clients options at both ends of the conflict spectrum. As a regional firm spread across six offices, clients in Costa Mesa should ask which attorneys work out of the Newport Beach office before signing on.

6. Burch Shepard Family Law Group, APC

• Attorney/Key Figure: Robert B. Burch, Founding Partner; Courtney Shepard, Founding Partner and Certified Family Law Specialist
• Headquarters: 20281 SW Birch Street, First Floor, Newport Beach, CA 92660
• Phone: (949) 502-4400
• Practice Areas: Divorce & Separation, Child Custody, Child Support, Spousal Support, Domestic Violence
• Firm Size: Boutique (about 8 attorneys), family law only
• Social Profiles: Avvo

Robert Burch has been licensed since 1997 and has practiced exclusively in family law for his entire career. His partner Courtney Shepard is a Certified Family Law Specialist who also practices family law exclusively, and both partners are recognized in the 2027 edition of The Best Lawyers in America for family law.

The firm sits near John Wayne Airport, a few minutes from Costa Mesa, and its roughly eight-attorney team gives it more bench depth than a solo office while keeping a family-law-only focus. The trade-off is a single office, so clients with matters in other counties will want to confirm coverage.

7. Bremer Whyte Brown & O’Meara LLP

• Attorney/Key Figure: Nicole Whyte, Founding Principal and CEO
• Headquarters: 20320 SW Birch Street, Second Floor, Newport Beach, CA 92660 (offices across the Western U.S.)
• Phone: (949) 221-1000
• Website: bremerwhyte.com
• Practice Areas: Family Law (High Net Worth Divorce, Child Custody & Visitation, Premarital Agreements, Domestic Violence), plus Real Estate, Construction, Estate Planning, and Complex Civil Litigation
• Firm Size: Large (more than 200 attorneys in 11 offices)

Nicole Whyte founded Bremer Whyte in 1997 after practicing law in Johannesburg, and she is a Certified Family Law Specialist and Fellow of the American Academy of Matrimonial Lawyers. The firm’s Newport Beach family law partners, including Nicole Nuzzo, Sheila Stiles, and Nicole Schmidt, are each certified as Family Law Specialists by the State Bar of California.

The family law group is known for representing high-net-worth clients with complex estates, and the firm’s real estate, estate planning, and litigation departments can be pulled in when a divorce involves property portfolios or business disputes. The trade-off is that family law is one department within a large multi-practice firm, so clients wanting a small-office feel may find a boutique a better match.

8. Sullivan Law & Associates

• Attorney/Key Figure: Richard P. Sullivan, Founder and Principal Attorney
• Headquarters: 620 Newport Center Dr Suite 1100, Newport Beach, CA 92660 (additional office in La Jolla)
• Phone: (949) 590-8100
• Website: sullivan-law.com
• Practice Areas: Divorce, High-Asset Divorce, Complex Business Valuations, Child Custody, Domestic Violence, Mediation
• Firm Size: Boutique with senior attorneys of 25+ years’ experience each

Richard P. Sullivan has practiced law since 1978, running his own office before a decade as a partner at Hughes & Sullivan and then founding Sullivan Law & Associates. He serves on the Executive Committee of the Orange County Bar Association’s Family Law Section and is recognized by The Best Lawyers in America for family law.

The firm emphasizes high-asset divorce and business valuation work, and in 2025 it expanded with a new office in La Jolla. The trade-off is that its high-asset positioning may be more firepower than a straightforward uncontested divorce needs.

9. Law Office of Kathryn Yarnal, APC

• Attorney/Key Figure: Kathryn A. Yarnal, Founder
• Headquarters: 555 Anton Blvd., Suite 150, Costa Mesa, CA 92626
• Phone: (714) 432-6370
• Practice Areas: Divorce & Separation, Child Custody, Child Support, Family Law Appeals
• Firm Size: Solo practice
• Social Profiles: Avvo

Kathryn Yarnal opened her Costa Mesa practice in 2019 after eight years as a senior attorney at Hughes & Hughes LLP. She is a member of both the Family Law and Appellate Law sections of the Orange County Bar Association, and her practice includes family law appeals alongside trial-level divorce and custody work.

Her focus is child-centered family law, and her Avvo profile shows a 5.0 average across 14 client reviews, with several noting her availability during custody proceedings. As a solo practitioner she offers a single point of contact throughout the case, though without the bench depth of a larger firm if a matter becomes very document-heavy.

10. Cordial Family Lawyers, LLP

• Attorney/Key Figure: Cheryl Kang Prout, Founding and Managing Partner
• Headquarters: 3151 Airway Avenue, Building E, Costa Mesa, CA 92626
• Phone: (949) 423-3185
• Practice Areas: Prenuptial Agreements, Postnuptial Agreements, Divorce Mediation, Divorce & Separation
• Firm Size: Boutique

Cheryl Kang Prout founded Cordial Family Lawyers to concentrate on agreement-based family law: prenuptial and postnuptial agreements, divorce mediation, and divorces that the parties want resolved efficiently. She has been licensed for about 12 years.

The firm is a strong fit for couples drafting a marital agreement or trying to settle a divorce through mediation rather than litigation. The trade-off follows from that focus: if you expect a trial-heavy custody fight, ask about the firm’s courtroom experience or consider a litigation-focused firm.

Frequently Asked Questions

Where are Costa Mesa divorce and custody cases filed?

All Orange County family law cases, including those from Costa Mesa, are filed at the Lamoreaux Justice Center, 341 The City Drive South, Orange, CA 92868. Hearings may be assigned to Lamoreaux or to family law departments at other county courthouses, including the Harbor Justice Center in Newport Beach. Lamoreaux also houses the Self-Help Center and the Family Law Facilitator’s office (Room 101) for people representing themselves.

What is a Certified Family Law Specialist, and should I look for one?

A Certified Family Law Specialist is an attorney certified by the State Bar of California Board of Legal Specialization after passing a family law examination, meeting substantial family law experience requirements, and completing ongoing specialized education. Several firms on this list have certified specialists among their attorneys, including Sarieh Family Law, Holstrom, Block & Parke, and Bremer Whyte Brown & O’Meara. Certification is a useful signal of depth, but direct access to your attorney, local court familiarity, and fit with your case type matter just as much.

How long does a divorce take in California?

California has a mandatory six-month waiting period: a divorce cannot become final until at least six months after the responding spouse is served or appears in the case. To file for divorce, one spouse must have lived in California for six months and in the county of filing for three months. Contested cases involving custody disputes or complex property division often take a year or longer.

How is child custody decided in Orange County?

Parents who cannot agree on custody or visitation must attend child custody mediation through Orange County Family Court Services before a judge decides the issue. The court bases its decision on the child’s best interests, considering factors such as each parent’s involvement, the child’s health and safety, and any history of domestic violence. Attorneys with minor’s counsel training, such as Christopher Engels at Engels O’Brien, bring added perspective on how children’s interests are presented in these cases.

How much does a family law attorney in Costa Mesa cost, and can my spouse be ordered to pay?

Most Orange County family law attorneys bill hourly against an upfront retainer, with total cost driven largely by how contested the case becomes. Under California Family Code section 2030, a judge can order the higher-earning spouse to contribute to the other spouse’s attorney’s fees so both sides have access to counsel. Some firms charge for the first meeting (Farzad & Ochoa offers a paid strategy session), while mediation-focused firms such as Cordial Family Lawyers can keep costs lower for couples who are able to cooperate.

Should I choose a large family law firm or a small one?

Large firms such as Minyard Morris and Bremer Whyte Brown & O’Meara offer deep benches of certified specialists and in-house resources for high-asset or business-owner divorces. Boutiques and solo practices such as Burch Shepard Family Law Group and the Law Office of Kathryn Yarnal typically offer more direct contact with the attorney you hire. The right choice depends on the complexity of your finances, how contested your case is likely to be, and how much personal attention you want throughout the process.
