We`ve mentioned company agreements on some blogs, and we thought we`d be more specific about them in this article. What is a company agreement and why does my LLC need it? A corporate agreement is a key document for an LLC with a solid legal basis. An agreement acceptable to all LLC directors, even if you are a single LLC member, will help your business as intended. Well-written company agreements should ensure the safety of LLC members. Below we will outline the basics of a good company agreement. When will a company agreement come into effect? A good corporate agreement will clearly indicate when it will be adopted by the LLC. This can be before, after or at the time of the creation of a business entity. If this is the case before, the company agreement will only come into effect with the creation of the LLC.
