Beverly Hills Divorce Lawyer Serving Los Angeles
Alphonse F. Provinziano is a Beverly Hills divorce and family law attorney serving clients throughout Los Angeles County. He is a Certified Family Law Specialist, a designation the State Bar of California awards to fewer than 1% of licensed attorneys, and a Fellow of the International Academy of Family Lawyers.
He founded Provinziano & Associates after working as a prosecutor, where he learned to build cases under pressure and present them at trial. That background shapes how he handles every matter today, whether it resolves through negotiation or ends up in front of a judge.
He holds a 10.0 Avvo rating and has been selected to Super Lawyers six consecutive years, from 2021 through 2026.
Alphonse Provinziano's Areas of Practice
Alphonse practices exclusively in family law. His work covers four areas: divorce and legal separation, child custody and support, international family law, and specialized matters like prenuptial agreements, grandparents’ rights, and domestic violence restraining orders.
Behind every case are real people and, often, children whose routines and sense of security are on the line. Alphonse takes a practical approach that protects his clients and keeps the focus on workable outcomes rather than unnecessary conflict.
In divorce and support matters, that often means getting the financial picture right early. Property division and support both depend on accurate information about what each spouse owns and earns.
He regularly handles complex and high-net-worth divorce matters, along with property division disputes where the outcome depends on careful financial analysis.
When the numbers are in dispute, he works with forensic accountants to trace income, find assets that are not being disclosed, and challenge figures the other side presents.
International Family Law Attorney
As a Fellow of the International Academy of Family Lawyers, Alphonse handles cross-border family law matters involving California. 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.
- 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.
- Winning a $700,000 home for a client by proving breach of fiduciary duty (hiding assets and failing to disclose financial information) by an ex-spouse, a decision later affirmed on appeal.
- 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.
- Discreet representation for public figures and executives
A 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 220 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:
- 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.
- 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.
- 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.
Why CFLS Certification & IAFL Fellowship Matter
Some California family law attorneys hold neither of these credentials. Alphonse holds both, and the difference matters depending on the nature of your case.
CFLS (Certified Family Law Specialist)
CFLS certification, issued by the State Bar of California Board of Legal Specialization, requires passing a written examination, peer review, and a demonstrated commitment to family law as a primary practice.
It signals deep familiarity with California-specific issues: how community property is characterized, how spousal support is calculated, and how Los Angeles County courts handle contested matters.
IAFL Fellow (International Academy of Family Lawyers)
The IAFL Fellowship is extended by invitation only to attorneys who have demonstrated expertise in international family law.
Alphonse has working relationships with family law practitioners across more than 50 countries and direct experience with the treaty obligations, including the Hague Convention, that govern most cross-border cases.
His case experience includes matters involving the UK, Mainland China, France, Switzerland, and other European countries.
Clients get an attorney who knows California family law from the inside and stays current on how other legal systems work through direct relationships with practitioners abroad.
Through IAFL conferences, roundtables, and ongoing exchanges with family lawyers from other countries, Alphonse brings firsthand knowledge of both sides to every cross-border case.
