Final answer:
The term for a disadvantage of a partnership when remaining partners are unwilling to buy out a retiring partner is referred to as partnership dissolution.
Step-by-step explanation:
A disadvantage of a partnership where remaining partners are unwilling to buy the share of a partner who retires can be referred to as partnership dissolution. This occurs when the structure of the partnership changes due to the departure of a member, which may necessitate the reformation or termination of the original partnership agreement. Unlike a limited liability partnership, a general partnership does not limit personal liability, and the partners are responsible for each other's actions and the business's debts, which can extend to personal assets.
