Which document allows homeowners to formalize their association among themselves?

The Articles of Incorporation are the correct document that enables homeowners to formalize their association among themselves. This legal document is filed with the state and establishes the homeowners' association (HOA) as a corporation. It defines the structure and purpose of the association, outlines the powers of the board of directors, and includes information about membership and governance. By incorporating, homeowners create a recognized legal entity that can enter into contracts, own property, and enforce community rules and regulations. This formalization is essential for providing a clear framework for decision-making and protecting the interests of the community.

The other options, while related to community organization in some way, do not serve the same purpose. A Community Charter typically outlines the principles and values of a community but does not formally establish a legal entity. A Founding Agreement may outline initial agreements among members but lacks the legal standing to create an organization. A Signed petition may be used to gauge support for an idea or initiative but does not formalize a structured legal association.
