You Built an Extraordinary Life Once. Your Next One Starts Now.
You built a life together, one that stretched across borders. A home filled with routines and memories. Children. Pets. Milestones. International assets in California, the UK, or both. Now, that chapter is changing, and the decisions ahead can affect where you live, how finances are handled, and what family life looks like across two jurisdictions.
Provinziano & Associates helps clients understand their legal options when a marriage or domestic partnership spanning California and the UK needs to change or come to an end. That includes one of the first and most consequential decisions in a cross-border case: where to file.
Our attorneys handle the California side of divorce, domestic partnership dissolution, legal separation, annulments, and related family law matters, coordinating with trusted family law solicitors and, where needed, barristers or advocates across UK jurisdictions.
Every day, we sit across from people just like you, navigating change that crosses borders, and we help them find their way through.
We Know This Is Bigger Than a Legal Process
The end of a marriage or domestic partnership is rarely just one decision, and when your life spans more than one country, it rarely feels like one problem either. It can feel like grief, pressure, uncertainty, and responsibility all at once. You may be trying to hold yourself together while also thinking about home, finances, family, and the version of life that comes after all of this, often across jurisdictions.
That is why this work cannot be treated like paperwork alone. Behind every filing is a person trying to make serious decisions in the middle of change. The Provinziano & Associates team approaches that with care, perspective, and an understanding that what is being sorted out is not only a case, but a life in transition.
Ending One Chapter. Owning the Next.
Ending a marriage or domestic partnership can take different legal forms. Some people know exactly what they want to do next. Others are still working through the difference between one option and another, or weighing where proceedings should be filed.
We work with UK legal professionals to inform strategy and help you understand your options across all relevant jurisdictions.
Divorce: When You Choose a Clean Break
Divorce, legally called dissolution of marriage in California, is the process of ending a marriage and resolving related issues.
Annulment: When Ending It Isn’t Enough, It Needs to Be Undone
In some situations, when legal grounds exist, a marriage may be declared void or voidable, treated as if it never happened.
Legal Separation: When You Need Change Without Ending the Marriage
In other cases, living separately while remaining legally married better fits your personal, financial, or religious circumstances. California legal separation and the treatment of judicial separation across UK jurisdictions can differ significantly, so where you file and under which law matters.
Domestic Partnership & Civil Partnership Dissolution
California domestic partnership dissolution is the legal process for ending a registered domestic partnership, but the rights, facts, and paperwork may differ from a divorce. UK civil partnership dissolution is handled under the law of the relevant UK jurisdiction, so coordination matters when a case has both California and UK dimensions.
Let’s Plan Your Next Move
We turn what you’ve been managing on your own into a legal plan that’s structured, strategic, and built for the complexity of a cross-border life.
The Issues That Often Follow
Choosing whether to dissolve a marriage or partnership, pursue separation, or seek an annulment is often only the first decision. The next step is understanding the issues that may be part of that choice, and how they’re treated differently across jurisdictions.
Marital Property & Cross-Border Assets
When your life is intertwined financially across two countries, separation raises hard questions.
What’s yours, what’s shared, and what needs to be untangled?
California real estate, UK property, businesses with operations on both sides, US retirement accounts, UK pensions, and offshore holdings each carries its own rules.
High-Value and Complex Asset Matters
Some divorces involve a higher level of financial complexity because of the type, value, or structure of the assets involved.
High-value assets, family trusts, investment portfolios, equity compensation, bonus structures, carried interest, and other substantial holdings often require coordinated valuation and disclosure across jurisdictions.
Spousal Support & Spousal Maintenance Questions
Separation doesn’t erase the years you spent building a shared life — contributing financially, supporting a partner’s career or education, raising children, or setting aside your own goals.
Questions about amount, duration, and changes over time often follow from the facts of the relationship and the life built during it.
The Difference Between Knowing the Law and Knowing What Works
The law gives you the rules. Experience tells you how to use them. After handling 3,000+ California family law cases, including those with international facets, we know how local judges think and how these cases tend to move.
We’ve learned when to press, when to settle, and what happens when people face this system without a plan.
When a case crosses into UK territory, we draw on established relationships with UK solicitors and barristers who bring the same depth on their side.
That’s why we don’t just know the law: we know how to move through it effectively, across jurisdictions.

The Provinziano & Associates Difference
Why UK Clients Choose Our Beverly Hills Firm
We Know How to Untangle Financial Lives
Cross-border divorce and separation can involve California and UK property, business interests on multiple sides, US retirement accounts and UK pensions, equity compensation, debts, support, and separate property claims. When needed, we work with forensic accountants, business valuators, California and UK tax specialists, appraisers, and other professionals, coordinating with local UK counsel to help protect your position across jurisdictions.
We Protect Your Privacy During a Personal Transition
While some court records are public by law in both California and UK jurisdictions, we take careful steps to limit unnecessary exposure wherever the process allows. That can include how we communicate, how sensitive information is handled, whether private resolution options may be appropriate, and how financial, parenting, or business details are presented during the case.
We Help You Prepare for the Issues Divorce Can Trigger
We help clients anticipate and prepare for each stage of the process instead of reacting after problems escalate. This may include requesting temporary or emergency orders for child custody and child support, spousal support, domestic violence restraining orders, and building strategies tailored to the evolving needs of your case.
We Don't Just Hear You, We Speak Your Language
At Provinziano & Associates, we believe no one and nothing should be lost in translation. Our attorneys primarily work in English, with support available in French, Italian, Spanish, Mandarin, Cantonese, Farsi, and Russian. If you prefer to communicate in another language not mentioned here, contact us and we'll confirm what's available for your situation.
Trial-Ready Representation When Agreement Is Not Enough
Some divorce and separation matters resolve through negotiation, mediation, or settlement. Others require court intervention. When your outcome depends on going to trial, our team brings the kind of courtroom skill and strategic focus that comes from years of litigation experience. Where parallel UK proceedings call for it, we coordinate with local barristers or advocates so your position is represented effectively across systems.
