Most legal problems in a small business are cheaper to prevent than to fix. A contract that spells things out clearly costs a few hundred dollars to have drafted or reviewed. Sorting out a dispute after the fact, without one, can cost a lot more than that, in money and in time you would rather spend running the business. Here are five documents worth having in place before you actually need them.
A Client Service Agreement
If you sell services rather than products, this is the single most important document you can have. A good service agreement spells out the scope of what you are actually delivering, payment terms and what happens if a payment is late, how either side can end the relationship, and who owns the work once it is finished.
Most disputes with clients come down to a disagreement about what was actually promised. A clear written agreement, signed before work starts, resolves that disagreement before it happens instead of after.
An Operating Agreement or Bylaws
If your business is set up as an LLC, you need an operating agreement. If it is a corporation, you need bylaws. For New York LLCs specifically, this is not a best practice. It is the law. Section 417 of New York's Limited Liability Company Law requires members to adopt a written operating agreement, and it has to happen within 90 days of filing your Articles of Organization. Most states treat an operating agreement as optional, which is why business owners who formed an LLC elsewhere are often surprised by it.
The agreement is not filed with the Department of State. It stays internal, which is exactly why it gets skipped so often, and why plenty of Long Island LLCs are quietly out of step with the requirement. If you do not have one, New York's default statutory rules govern your business instead of your own intentions, and those defaults rarely match what the owners actually agreed to. The classic example: two partners assume they are equal owners, but one put in most of the startup money, and nothing in writing settles it once the business becomes profitable.
The agreement spells out who owns what percentage, how decisions get made, what happens if an owner wants to leave or sell their share, and how profits are distributed. Even single-member LLCs benefit, since the document helps demonstrate that the business is genuinely a separate legal entity if your liability protection is ever tested.
One related New York obligation catches people out. New LLCs must publish notice of formation once a week for six weeks in two newspapers designated by the county clerk where the business is located, and it has to be done within 120 days of formation. In Nassau and Suffolk that means working through your county clerk rather than picking papers yourself, and an LLC that misses the deadline can have its authority to do business suspended until it catches up.
You may also have seen headlines about the New York LLC Transparency Act, which took effect January 1, 2026. As the law currently stands, its filing requirement applies only to LLCs formed outside the United States that are authorized to do business in New York. A typical Long Island LLC formed in New York does not have to file, though that could change if the legislature amends the law, so it is worth checking again with your attorney or accountant.
Employee and Contractor Agreements
Whether someone working for you is an employee or an independent contractor is not just a formality. It affects taxes, insurance, and your legal exposure if that classification turns out to be wrong. A written agreement that clearly defines the relationship, and matches how the work actually happens day to day, protects you if that classification is ever questioned. We covered some of what independent contractor status actually involves in this earlier guide.
For actual employees, a basic offer letter or employment agreement covering pay, role, and at-will status (New York is an at-will employment state, with some exceptions) is worth having even for a very small team.
A Privacy Policy and Terms of Service
If your business has a website that collects any information at all, an email signup, a contact form, an online order, you need a privacy policy explaining what you collect and how you use it. Depending on your business and what data you handle, you may also have specific legal obligations around it, so this is worth a real conversation with a lawyer rather than a generic template if you collect anything beyond basic contact information.
A terms of service page sets expectations for anyone using your website or ordering from you, including how disputes get handled and what you are and are not responsible for.
An NDA Template
A non-disclosure agreement is worth having ready any time you are about to share sensitive information with a vendor, a potential partner, or someone you are considering hiring, before a formal contract is in place. Having a template ready means you can send it over in five minutes instead of scrambling to draft one when the conversation is already happening.
None of these documents need to be complicated or expensive to put together. What matters is having them in place before you need them, not after.
Common Questions
Can I use a free template instead of hiring a lawyer?
For a straightforward single-member LLC or a basic NDA, a solid template is often reasonable. It stops being reasonable the moment there is more than one owner, outside money, or unequal contributions. Those are exactly the situations where generic language fails, and where the cost of getting it wrong dwarfs the cost of an hour of legal review.
My LLC is a few years old and never adopted an operating agreement. What now?
Talk to an attorney about adopting one. The 90-day window in the statute has passed, and courts have not always agreed on how to treat an agreement adopted late, but having a signed agreement in place is generally better than continuing without one. An attorney can advise on how to handle the gap for your specific situation, particularly if there have been ownership changes or disputes in the meantime.
Does a handshake agreement with a client hold up?
Sometimes, but proving what was actually agreed is the hard part, and that burden usually lands on whoever is owed money. Certain agreements also have to be in writing to be enforceable at all. A short written scope and payment term beats a long verbal understanding.
Do I need a privacy policy if my site only has a contact form?
A contact form collects personal information, so yes, a privacy policy is appropriate. New York's data security law also applies to businesses holding private information about New York residents, which is worth understanding alongside the policy itself.
