About Alphonse F. Provinziano
Alphonse Francis Provinziano is a Beverly Hills divorce and family law attorney serving clients in Los Angeles and throughout California.
His practice spans the full range of family law, with particular experience in high-net-worth and ultra-high-net-worth cases and California cases with interstate or international elements.
He is a Certified Family Law Specialist, recognized by the State Bar of California Board of Legal Specialization, and a Fellow of the International Academy of Family Lawyers.
Prior to founding Provinziano & Associates in 2008, Alphonse served as a Deputy District Attorney in San Bernardino County, where he developed extensive experience preparing and presenting cases in court. He later served as a Temporary Judge for the Los Angeles Superior Court from 2018 to 2022.
That background shapes how he approaches each case and the resolution strategy he pursues, whether through mediation, collaborative divorce, private settlement, or litigation. Alphonse has since handled approximately 2,000 family law cases and personally conducted more than 250 trials.
He holds a 10.0 Avvo rating and has received the Avvo Client’s Choice Award eight times. He has also been selected to California Super Lawyers for seven consecutive years, recognized by the Daily Journal as a Top Family Law Attorney for four consecutive years, and named to Los Angeles Magazine’s Best of L.A. Legal 2026 list.
Alphonse Provinziano's Areas of Practice
Alphonse practices exclusively in family law. His work includes divorce and legal separation, child custody and support, international family law, and specialized matters like guardianships, prenuptial agreements, grandparents’ rights, and domestic violence restraining orders.
He represents individuals and families whose family law matter may involve substantial assets, demanding careers, and important decisions about children.
His clients include physicians, finance professionals, executives, and people in technology, media, and other industries where compensation, business interests, or professional obligations can affect the case.
When a case calls for specialized analysis, Alphonse works with the appropriate professionals to address technical or disputed issues and support the legal strategy with reliable evidence.
International Family Law Leadership
As a Fellow of the International Academy of Family Lawyers and a member of the Association of European Attorneys, Alphonse represents clients in California family law cases with international elements.
He regularly serves as California counsel in these cases, working alongside attorneys in the other country so nothing falls through the gaps between the legal systems.
His international work covers cross-border divorce, custody, support, and property division. He also drafts and enforces prenuptial and postnuptial agreements for couples with ties or assets in more than one country, and handles the enforcement of foreign orders in California and California orders abroad.
In addition to representing cross-border clients, Alphonse also hosts roundtable discussions comparing California family law with legal systems abroad and takes an active role in organizing and speaking at international family law conferences, including programs with the IAFL and ABAL.
In 2026, he represented the California perspective on modern and unusual assets at the IAFL European Chapter Conference in Barcelona and spoke at an international conference in Sofia marking 45 years of the Hague Child Abduction Convention.
- Securing grandparent visitation rights over the objections of both parents, proving the case under the clear and convincing evidence standard, a rare legal victory in California.

- Successfully arguing a motion in limine (a pre-trial request to exclude certain evidence) that resulted in his client receiving the entire family residence and 401(k) without the need for a multi-day trial.
- International family law, including returning abducted children under the Hague Convention, resolving cross-border jurisdiction questions, coordinating mirror agreements to reduce enforcement risk overseas, handling international support, and seeking recognition and enforcement of foreign orders.

Proven Track Record in High-Stakes Litigation
Most family law cases settle before trial. How well they settle depends on the preparation behind them. With more than 250 trials, Alphonse prepares every case as if it will go the distance.
Three results from Alphonse’s case history show the level he operates at:
- Family Residence Awarded After Undisclosed Assets Were Proven
He won a $700,000 family home for a client by proving the other spouse had hidden assets and failed to disclose financial information. The decision was affirmed on appeal. - Residence and Retirement Account Awarded Before Trial
He filed a motion in limine, a pre-trial request to exclude certain evidence, that resulted in his client receiving the entire family residence and 401(k) without proceeding to a multi-day trial. - Grandparent Visitation Granted Over Both Parents' Objections
He secured grandparent visitation rights over the objections of both parents, winning under the clear and convincing evidence standard. That outcome is rare under California law.

Above all, he ensures that children’s best interests and family stability remain at the heart of every decision.
