Bylaws and Articles of Incorporation are both very important documents relating to a business. Though similar, the two are different in form, features and function. One way to think about the difference is to liken it to the difference between the Constitution and individual laws.
Articles of Incorporation
The Articles of Incorporation, like the Constitution, provide the broad framework of the Association, the founding documents. They are more general in detail, outlaying the legal name, registered agent, and the overall purpose and basis of existence.
In contrast, the Bylaws are internal edicts that address much more specific issues in greater detail, but with the crucial goal as to always be consistent with the Articles of Incorporation. The By-Laws, in practical terms, have a greater influence on the day-to-day operations of the Association.
