Origin: An Engineer Turned Appellate Family Lawyer
Keith Berkshire earned his J.D. from the University of Houston Law Center in 2005 and was admitted to the Arizona Bar the same year, after an earlier career as an engineer at Goodrich Aerostructures. He built his family law practice in the Phoenix metro area before founding Berkshire Law Office in Tempe, where the firm has since grown into a dedicated family law practice handling matters from uncontested divorce and paternity to complex, high-net-worth dissolutions and appeals.
Practice Areas
Berkshire Law Office practices across the full range of Arizona family law: divorce and legal separation, high-net-worth and business-owner divorce, legal decision-making (custody) and parenting time, child support, paternity, spousal maintenance, premarital and postmarital agreements, property division, orders of protection, and parental rights terminations and guardianships where juvenile law intersects with family law. The firm’s own materials describe handling divorce cases spanning estate values from tens of millions of dollars down to matters where there was only debt to divide.
The Appellate Practice
What distinguishes Berkshire from most family law practitioners is the volume and reach of his appellate work. According to the firm’s own site, Berkshire has authored or argued more published family law opinions than any other attorney in Arizona — 40 at the Arizona Court of Appeals and Arizona Supreme Court combined, as of his most recent published bio. Berkshire is also a member of the U.S. Patent and Trademark Office bar (License 55,856) and served on the Arizona Supreme Court’s task force that rewrote the Arizona Rules of Family Law Procedure in 2018.
Track Record
Arizona family court trial outcomes are generally confidential, so unlike a personal injury settlement table, the public record here is appellate. The following are matters of public record:
| CASE | COURT / YEAR |
| Howell v. Howell | U.S. Supreme Court, 2017 (137 S. Ct. 1400) — military retirement pay divisibility in divorce |
| Hoffman v. Miller | Arizona Court of Appeals, 255 Ariz. 165 (2023) |
| Tiger v. Pennel | Arizona Court of Appeals, 2024 |
| Skoglund v. Barbour | Arizona Court of Appeals, 2024 |
| Saba v. Khoury; Volk v. Brame; McLaughlin v. Jones; Woyton v. Ward; Gonzalez-Gunter v. Gunter; Barron v. Barron | Arizona Court of Appeals / Arizona Supreme Court (various years) |
Past-Results Disclaimer: These are matters of published appellate record, not settlement figures. Every case is different, and a published opinion in one matter does not guarantee any outcome in another.
Client Voice
Reviews on Avvo describe Berkshire as strategic and highly prepared, with several clients specifically citing his recall of case detail months after discussions and his handling of contentious, multi-year custody litigation. One reviewer described a three-year case she felt was decided in her family’s favor; another, in a review dated 2017, called him a formidable advocate in a complex divorce.
Community
Berkshire is a frequent CLE lecturer, teaching other attorneys and judges on legal decision-making (custody) and appellate practice, and has served as an expert witness in family law matters. He authored the Family Law section of the State Bar of Arizona’s Arizona Appellate Handbook (2021) and has served on the State Bar’s Family Law Section Committee on Case Law Updates and its Family Practice and Procedure Committee.
Recognition
Berkshire holds Arizona’s Board-Certified Family Law Specialist credential (since 2011) — a designation issued by the State Bar of Arizona’s Board of Legal Specialization, not a marketing award. He is a Fellow of the American Academy of Matrimonial Lawyers, one of 36 in Arizona. He has been AV-rated by Martindale-Hubbell since 2012, listed in Best Lawyers in America, named Best Lawyers’ Family Law “Lawyer of the Year” for Phoenix in 2022 and 2024, and selected to Super Lawyers every year since 2012, including the Top 50 Lawyers in Arizona across all practice areas in 2017, 2018, 2019, and 2024.
The Arizona Legal Backdrop
What follows is general legal information, not legal advice.
Arizona divorce and legal separation proceed under A.R.S. § 25-312. Custody and parenting time decisions turn on the best-interests factors in A.R.S. § 25-403. Child support follows the state’s guidelines under A.R.S. § 25-320, and spousal maintenance is governed by A.R.S. § 25-319. Arizona is a community property state, with a presumption of equal division under A.R.S. § 25-211. Howell v. Howell itself turned on a related but distinct question: federal preemption of state courts’ authority to divide military disability-related retirement pay.
The Awesome Attorneys Assessment
Berkshire Law Office’s core strength is unusual and specific: an appellate record in family law that few, if any, Arizona attorneys can match, backed by a genuine, individually-documented Board Certification and a U.S. Supreme Court win. That makes the firm a strong fit for complex, high-conflict, or high-net-worth matters likely to be contested or appealed.
The honest caveat: this is a retainer-based, litigation-and-appeals-oriented practice built around one certified specialist’s national-caliber appellate profile — not the lowest-cost or fastest option for a straightforward, uncontested matter, and clients should expect a fee structure that reflects the firm’s specialization.
