What is required of real estate licensees in terms of contract modifications in Illinois?

In Illinois, real estate licensees are required to receive written consent from all parties involved before making any modifications to contracts. This requirement is in place to ensure transparency and mutual agreement on any changes, which helps protect the interests of all parties involved in the transaction. Modifying a contract without proper consent could lead to disputes or claims of unauthorized alterations, potentially invalidating the contract. Thus, obtaining written consent not only adheres to legal and ethical standards but also fosters trust and clarity in real estate transactions.

The other options suggest varying degrees of authority to modify contracts without consent or impose restrictions that do not reflect the legal framework governing real estate practices in Illinois. Therefore, the necessity for written consent is critical to maintaining compliance and ensuring that all parties are on the same page regarding any changes made to a contract.
