A limited liabilty company is a business entity similar to a corporation that is easier to create and easier to dissolve than a corporation. Pretty much all states in this country recognize the legality of a limited liability company.If you foresee your business being run through this limited liability company to continuing on indefinitiely, then you should keep the duration of this entity as perpetual. It makes things much easier for the members this way.There is really no reason to add a clause that the limited liability company will continue on in the event of the withdrawal or death of a member in that under the laws of all states recognizing limited liability companies, they continue on as a viable entity in the event of the change of member ownership.Good question.
