The Co Tenancy Agreement format in Illinois is a legal document designed for unmarried individuals who intend to purchase and co-own a property as joint tenants with the right of survivorship. This agreement outlines the responsibilities and rights of each party regarding property ownership, including expense sharing for mortgage payments, taxes, and maintenance costs. It requires the formation of a joint checking account to facilitate these financial obligations and provides terms for resolving defaults. Additionally, the contract stipulates conditions under which a party may sell or transfer their interest in the property, including the requirement for a written offer to the other party. It emphasizes the importance of mutual consent for significant financial decisions, like mortgages or assignments of interest. This form is crucial for attorneys, partners, owners, associates, paralegals, and legal assistants as it helps to clarify ownership rights and financial responsibilities, promote transparency between co-owners, and provide a framework for dispute resolution should disagreements arise. Overall, it serves as an essential tool for ensuring a clear and enforceable arrangement between co-owners in Illinois.
