Final answer:
A general partnership or Limited Liability Company (LLC) would allow 3 physicians to share the ownership and management of a medical office, offering them collective operation with shared profits and responsibilities.
Step-by-step explanation:
Business Structure for Shared Ownership
For 3 physicians looking to share ownership of a medical office, a general partnership would allow them to collectively own and manage the business. In a general partnership, each partner is involved in the operations of the business and shares in the responsibilities as well as the profits. An alternative is forming a Limited Liability Company (LLC), which offers protection to each physician's personal assets from the business's liabilities, while still allowing them to operate and manage the medical office together. Both these business structures are common when multiple individuals seek shared ownership and have specific implications for taxation and legal responsibility.
