As a small business owner, it's essential to establish a strong foundation by registering your business, establishing separate business bank accounts, using solid contracts, registering your trademarks, and completing estate planning documents. Registering your business legitimizes it for consumers, provides access to grants and loans, allows you to receive an EIN, and protects personal funds in case of lawsuits. Using solid contracts protects your business from disputes and ensures credibility with customers. Registering your trademarks prevents infringement on intellectual property and protects you from costly mistakes. Completing estate planning documents puts you in control of your business's future and provides protection in case of your passing or incapacitation. By following these five legal essentials, small business owners can protect their brand, focus on growth, and establish a successful business.
