The Washington Certificate of Limited Partnership is a legal document filed with the Washington Secretary of State that creates a limited partnership under the state's laws. The certificate is a written agreement between two or more persons who want to form a business entity, and it must be filed with the state to be legally recognized. The limited partnership is a business structure that has two types of partners — general partners and limited partners. General partners manage the business and are personally liable for any liabilities and debts of the business, while limited partners are only liable to the extent of their investment in the business. A Washington Certificate of Limited Partnership must contain the name and address of each partner, the name and address of the business, the purpose of the business, the duration of the business, the name and address of the registered agent, and the signature of the general partner(s). There are two types of Washington Certificates of Limited Partnership — a basic certificate and an amended certificate. The basic certificate is used to create a new limited partnership, while an amended certificate is used to make changes to an existing limited partnership.
