Short answer:  yes.  Some time ago I posted a brief article on my LinkedIn blog entitled "Estate Planning:  Do I Need It?".  See the link here:

I share it in this forum because many of the points I address in this article are applicable to business owners seeking to sell or transfer their business interests.  While it's crucial to address the immediate intricacies of a sale/purchase transaction, often it's even more crucial to address the long-term planning concerns that estate planning routinely analyzes. 

I invite fellow members to give the attached link a read and I invite your feedback.  For additional information on estate planning, feel free to visit my blog, "Planning Your Future":    https://christopherfloss.wordpress.com/
