Arizona Certificate of Limited Partnership (ACLU) is a legal document that is filed with the Arizona Corporation Commission to establish a limited partnership. It is used to form a business entity in the state of Arizona and provides evidence of the legal existence of the partnership. ACLU includes basic information about the partnership, including its name, registered office and agent, duration, and purpose. It also includes the name, address, and signature of each partner, along with the partnership agreement. There are two types of Arizona Certificate of Limited Partnership: the traditional Certificate of Limited Partnership (CLP) and the Certificate of Limited Liability Partnership (LLP). The traditional CLP is the most common type and provides limited liability protection to the partners. The LLP provides even greater protection to the partners, as it shields them from personal liability for the debts and obligations of the partnership.
