Business Law Attorney for Long Island Companies
From the day you form the company to the day you hand it off, every stage of your business has legal weight. One Deer Park firm covers all of it.
Clear Legal Guidance for Real Business Decisions
As a business law attorney serving Long Island, Shari represents company owners across Suffolk County, Nassau County, and New York with practical advice and strong courtroom advocacy. Running a business means making decisions that carry real legal consequences, from forming a company to signing contracts to handling the dispute you hoped would never come. Business law is one of the core areas of practice at Sugarman Law, and it works differently here than at most firms: the attorney who forms your company is the same one who drafts your contracts, stands behind them in court, and eventually plans your exit.
That continuity matters. Most legal problems businesses face were preventable at an earlier stage, and a firm that sees the whole lifecycle catches them before they cost you.
Legal Support at Every Stage of Your Business
A startup needs different legal work than a twenty-year-old company. Find your stage.
Starting a New Business in New York
The entity you choose affects your personal liability, your taxes, and how ownership works, and forming an LLC or corporation without proper planning creates issues with ownership rights, management authority, and future disputes. We handle entity selection, state filings, New York's publication requirement, and the internal agreements that protect everyone involved from day one.
Explore Startup FormationThe Agreements Your Business Runs On
Contracts are the backbone of most business relationships. Whether you're working with customers, vendors, employees, partners, or landlords, clear and enforceable agreements reduce misunderstandings and protect your interests, and any important contract deserves a review before you sign. Vague payment terms, broad liability clauses, and weak dispute language hide in agreements that look straightforward.
Explore Business ContractsWhen a Dispute Threatens What You Built
Contract breaches, partnership conflicts, payment disputes, and ownership disagreements can disrupt operations fast if handled incorrectly. Early legal advice protects your position, and in many cases resolves the matter before it becomes prolonged litigation. When court is unavoidable, we litigate in the Suffolk and Nassau courts where these cases are heard.

Ownership changes happen for many reasons: retirement, sale, disability, death, or a partner exit. Without a clear plan, even strong businesses face internal conflict and financial uncertainty. Buy-sell agreements, succession plans, and transfer documents decide the future of the company in writing, on your terms, while you're still the one holding the pen.

Our office is in Deer Park, and most of our business law clients are in Suffolk County and Nassau County. We work with family-owned companies, service businesses, professional practices, and small commercial operations across Long Island. We know the local market and the practical problems business owners here run into, because we've been part of this business community since 2006.
Owners choose us for the way the relationship works: quick responses, plain-language explanations, and honest advice about what's worth spending legal fees on and what isn't. And because business ownership and personal planning overlap, many of our business clients also work with the firm's estate planning practice when succession and legacy questions come up.

The cost of a business lawyer on Long Island depends on the type and complexity of the legal work. Simple services like contract review or business formation usually cost less than litigation or ongoing counsel. A free consultation can determine the right level of legal support for your business.
You are not legally required to hire a lawyer to form an LLC in New York, but legal guidance helps you avoid mistakes. A business attorney can assist with entity selection, filing requirements, the state's publication requirement, operating agreements, and ownership structure to better protect your interests from the start.
A business contract review should look closely at payment terms, scope of work, deadlines, liability clauses, termination rights, confidentiality provisions, and dispute resolution language. A lawyer can identify unclear or risky terms before you sign.
Commercial litigation in New York can take several months to more than a year depending on the complexity of the dispute, the court schedule, and whether the case settles early. Some matters resolve quickly through negotiation, while others require a longer court process.
