Answer:
The business cease to exists unless sold or taken over by Joe's heirs.
Step-by-step explanation:
Sole proprietorship is a term that describes the business enterprise which is owned or run by just one person known as the sole trader. In other words, sole proprietorship is a one man's business.
One of the major drawbacks of this kind of business is the fact that when a sole proprietor is sick or incapacitated, his/her business would suffer or cease to exist unless he/she sells it or allows family members (heirs) to take over its management or ownership.
