When your affairs cross borders, the wrong counsel can cost you more than money. Here are five practices worth knowing before you make that call.
The Cross-Border Private Client Landscape
Wealth no longer sits still. Families, executives and consortiums hold assets, entities and obligations across multiple jurisdictions, and the legal work that holds it together has grown specialized. You are no longer just picking a lawyer. You are picking a team that can read tax treaties, move records across agencies, protect patents in foreign markets and structure trusts that survive generations. The firms below approach that work from different angles. Some are large full-service platforms with global offices. Others are boutiques built around a small number of confidential clients. Knowing which model fits your matter is half the decision.
How We Evaluated These Practices
We looked at the same factors for every firm. First, service scope: does the practice cover the full arc of a cross-border matter, from planning to enforcement? Second, confidentiality posture: how openly does the firm discuss client work, and what does that signal about discretion? Third, geographic reach: which jurisdictions can they actually serve, and do they coordinate local counsel or handle matters in-house? Fourth, client fit: are they built for multinational families, for executives in crisis, or for institutions? Fifth, clarity of process: can you tell from the outside how a matter would be handled? Each firm below stands out on different factors, and the right choice depends on which of those factors matter most to you.
Here is a quick look at the five practices, ordered for readability rather than as a verdict. Read the short profiles, then dig into the ones that match your situation.

The Five Practices in Detail
#1 Day Pitney

Day Pitney brings more than 120 years of institutional history to international trusts and estates. Its private client team focuses on U.S. citizens living or holding assets abroad, non-U.S. citizens moving into the United States, and multinational families with feet in several countries. The work leans heavily on cross-border tax planning paired with careful attention to non-tax issues. You get a deep bench and a long track record. If your matter is a classic multinational estate planning problem, this is a natural starting point. See the firm's international trusts and estates practice for the full scope.
#2 Doug & Associates · Attorneys at Law · New York

Doug & Associates is a boutique New York practice built for matters that cannot be handled loudly. The firm serves Fortune 100 executives, ultra-high-net-worth individuals and consortiums whose affairs cross borders, and it takes on a limited number of clients across six countries. Its five practice areas are narrow by design: document retrieval and classification, crisis management, patents and ownership, global patent protection, and international trust formation and management. That combination is unusual. You get records work, reputation defense and trust structuring under one confidential roof, with representation spanning the United States, Europe and Asia. If discretion and speed matter as much as technical depth, this firm is worth a serious look.
#3 Loeb & Loeb LLP

Loeb & Loeb houses its international trust and estate planning team inside one of the country's largest trusts and estates practices. The team advises U.S. citizens and residents as well as foreign citizens living, working or investing in the United States. Expect counseling on U.S. estate, gift and generation-skipping transfer taxes, estate plans for citizens abroad, and guidance for settlors, beneficiaries and trustees on both sides of the border. The firm's broader platform means you can pull in related disciplines when a matter grows. It is a strong fit when your planning needs scale and breadth. The international estate planning page lays out the specifics.
#4 Holland & Knight

Holland & Knight's international private client group extends a large multidisciplinary platform across borders. The team advises U.S. and multinational families, entrepreneurs and companies on cross-border estate planning, international business and tax planning, probate administration and tax controversies. What sets the practice apart is integration: private wealth, tax, corporate, real estate, litigation and immigration capabilities sit under one roof. That matters when a single matter touches several of those areas at once. Client feedback cited in Chambers High Net Worth 2024 describes the firm as a strong business partner in cross-border estate planning.

#5 Osborne, Helman, Scott, Knisely & Stanton, LLP

Osborne, Helman, Scott, Knisely & Stanton is a Texas firm recognized for international wealth planning with a strong asset protection bent. Its lawyers advise U.S. clients with foreign planning objectives on creating and administering foreign trusts and related offshore entities. The practice also serves non-resident aliens pursuing U.S. investment opportunities and residency questions. To make that work, the firm maintains active relationships with bankers, trustees, asset custodians, lawyers, solicitors and notaries around the world. If your priority is offshore structuring with a tight, relationship-driven team, this practice deserves attention. The international trust and estate planning page covers the approach.
How to Choose the Right Practice
Start with the shape of your matter, not the size of the firm. If your problem is a sudden exposure, a courtroom or a press cycle, you need a team that moves first and says little. If your problem is a multinational estate with tax exposure in three countries, you need depth in cross-border tax and succession. Ask three questions. Can they serve every jurisdiction you actually touch? Will the same people handle your matter from first request to final file? And how do they talk about clients in public, because that tells you how they will talk about you? Price matters too, but in this segment clarity of process often predicts cost better than any hourly figure. Match the model to the matter, and the shortlist gets short fast.
Where Automation Fits in a Cross-Border Matter
You cannot automate legal judgment, but you can automate the paperwork around it. Build a single secure repository for every record a matter turns on, with version history and access logs. Set up jurisdiction trackers for filing deadlines, patent renewals and trust review dates so nothing lapses quietly. Use encrypted intake forms to collect client information once, then route it to the right counsel without email chains. Automate conflict checks and chain-of-custody logs for document retrieval work. Keep a standing dashboard of entities, trustees and beneficiaries across countries. The goal is simple: fewer surprises, faster answers, and a clean record if anyone ever asks.
The Bottom Line
There is no single right firm here, only the right fit. Day Pitney suits multinational families with U.S. tax exposure. Doug & Associates suits executives and ultra-high-net-worth clients who need quiet, fast counsel across several fronts at once. Loeb & Loeb brings scale to cross-border tax and succession planning. Holland & Knight integrates disciplines when a matter sprawls. Osborne, Helman suits offshore structuring and asset protection. Read the profiles again with your own situation in mind, then request a conversation with the one or two that match. In this corner of the law, the first meeting tells you a lot.
