For Shanice, who is risk-averse and wants to protect herself from business liabilities, the best legal business structure would be an LLC (Limited Liability Company).
An LLC provides limited liability protection, which means that her personal assets would generally be protected from business debts and liabilities. This structure offers a good balance of flexibility in management and the benefits of pass-through taxation, making it a popular choice for small business owners.
In contrast, a sole proprietorship does not offer personal liability protection, which could expose Shanice's personal assets to risk. A franchise involves operating under an established brand but may not provide the same level of personal liability protection as an LLC. A referral is not a business structure but rather a method of generating business, so it does not apply here.
Therefore, the LLC is the best choice for her.
