Business Law

Practical Counsel. Strategic Partnership.

At Brann & Isaacson, business law is not a sideline—it’s our foundation. For nearly a century, we’ve guided companies through critical inflection points: from restructuring banks during the Great Depression, to advising L.L. Bean as it grew to become Maine’s largest private employer, to helping today’s startups reach their next level of growth.  We help our clients navigate through the ever-changing business and regulatory landscapes.

We represent growth-minded businesses—from family-owned companies to national brands—address complex legal issues with clarity, speed, and efficiency. Our team combines legal insight with business fluency, bringing practical, cost-effective solutions to the table.  

A Dedicated Relationship, Not Just a File Number
Each client works with a lead attorney who functions as a strategic adviser—someone who understands your business, your goals, and your industry. They’re accessible, responsive, and deeply invested in your success. When a specific issue arises, we loop in the right subject-matter expert, without ever dropping the thread. You stay focused on your business; we stay focused on you.

Where We Excel

Business Formation & Governance

We guide clients through forming the right business structure—LLC, C-Corp, electing S-Corp treatment, partnership, ESOP, or non-profit—tailored to their tax, liability, and growth goals. Our ongoing counsel ensures that governance, ethics, and structure support your long-term strategy.

Regulatory Compliance

We provide clients with solutions to the myriad of complex federal and state laws and regulations they face. In today’s business world, a company must contend not only with its own state’s regulations and laws, but those of every other state into which it sells.   We have a special expertise in advising clients on interstate and worldwide business issues, including help clients optimize vendor and contractor relationships.

Mergers, Acquisitions & Transactions

Whether it’s an acquisition, sale, strategic investment, or joint venture, we know how to get deals done.  We handle everything from real estate and licensing to financing and regulatory due diligence. The result? Fewer surprises, smoother execution.

Employment & Labor Counsel

We support employers with proactive advice and rapid response on hiring, handbooks, compliance, and litigation. Whether you’re managing a union workforce or navigating a sensitive termination, we help you move forward with confidence and care.

Employment Practice

Succession & Estate Planning

Your business’s future is personal. Ownership transitions—whether within the family or to new leadership—require legal and personal foresight. We provide the planning and structures that protect both the business and the people behind it. Our approach aligns estate planning with business continuity, from simple wills to multi-generational tax strategies.
