New Jersey Business Attorney — Built for Operators
The Business Attorney Who Has Actually Run a Business. Strategic Counsel for New Jersey's Owners and Operators.
Most business attorneys have never run a business. Sean Branigan has. He has built companies, managed employees, negotiated contracts, dealt with difficult partners, and navigated the full range of challenges that come with owning and operating a business in New Jersey. That experience is not incidental — it is the foundation of how he practices.
Sean holds professional education from Harvard Business School and Harvard Medical School, bringing financial valuation expertise and strategic thinking to every business matter. He is a business broker through Transworld Business Advisors, with deep experience in acquisitions, diligence, and business transitions. He is not just a lawyer — he is a strategic operator who happens to be one of the most experienced attorneys in New Jersey.
Business owners face a unique category of legal risk — one that keeps them up at night. Partnership disputes, contract breaches, regulatory investigations, employment claims, and reputation attacks can arrive without warning and escalate quickly. Sean is the attorney who moves fast, thinks strategically, and does not let problems fester.
Whether you are a startup founder, a family business owner, a real estate developer, or a multi-location operator — Sean provides the kind of counsel that actually moves the needle. Not just legal advice. Strategic guidance from someone who understands what you are building and what you cannot afford to lose.

What Sean Handles in Business & Corporate Law
Partnership & Shareholder Disputes
Partnership disputes can destroy businesses that took decades to build. Sean resolves these disputes — through negotiation, mediation, or litigation — with the speed and precision that business survival demands.
Contract Drafting & Disputes
From vendor agreements to executive employment contracts to commercial leases — Sean drafts, reviews, and litigates contracts with the perspective of someone who understands the business consequences of every clause.
Business Acquisitions & Sales
As a licensed business broker through Transworld Business Advisors, Sean brings unique expertise to business acquisitions and sales — handling due diligence, confidentiality agreements, purchase agreements, and transition disputes.
Regulatory Defense
New Jersey's regulatory environment is aggressive. Sean defends businesses against regulatory investigations, licensing challenges, and agency enforcement actions — at the state and federal level.
Business Formation & Governance
LLCs, corporations, partnerships, and operating agreements — Sean structures businesses to minimize liability, protect assets, and position owners for long-term success.
Non-Compete & Trade Secret Disputes
Protecting your business from departing employees who take clients, trade secrets, or key relationships requires immediate, aggressive action. Sean has obtained emergency injunctions in these cases.
Commercial Litigation
When business disputes cannot be resolved through negotiation, Sean takes them to court — with the preparation and trial experience to win.
Crisis Management & Reputation Defense
When a business crisis hits — a public accusation, a regulatory investigation, a media story — Sean manages the legal response while protecting the business's reputation and future.

Common Questions
Frequently Asked Questions
What is the most common mistake business owners make when a dispute arises?
Waiting. Business disputes escalate quickly, and the decisions made in the first days — what you say, what you do, what you sign — can determine the outcome. Sean's first advice is always: call before you act. A free diagnosis costs nothing. A mistake can cost everything.
Do I need a lawyer to form an LLC in New Jersey?
You are not legally required to use an attorney to form an LLC, but the operating agreement — the document that governs the relationship between members — is where most business disputes originate. A poorly drafted operating agreement can cost far more than the attorney's fee to draft it correctly.
How does Sean's business broker experience help his clients?
Sean's experience as a business broker through Transworld Business Advisors gives him a unique perspective on business acquisitions and sales. He understands valuation, due diligence, deal structure, and the practical realities of business transitions — making him a more effective advocate in acquisition disputes and a more strategic advisor in deal negotiations.
What should I do if a former employee is soliciting my clients?
Act immediately. If you have a non-solicitation agreement, Sean can seek an emergency injunction to stop the solicitation. Even without a written agreement, New Jersey law protects trade secrets and confidential business information. Call Sean before the damage becomes irreversible.
How does Sean handle business crises?
Sean approaches business crises the way a special operations unit approaches a mission: assess the situation, identify the threats, develop a strategy, and execute with precision. He manages the legal response, coordinates with other advisors, and protects the business's interests at every stage.
