In terms of documentation, by law the developer must have recorded the condo declarations and documents prior to the sale of the very first unit. The declaration declares what are common elements of the condominium, percentage of ownership rights in the common elements, what is covered in your monthly assessment, what your common insurance covers in the event of a claim etc etc In addition, there are rules and regulations that you must abide by will residing in the unit. You should have received a copy of the declaration and bylaws prior to closing on your unit.
Currently, if issues arise you need to address them directly to the developer or the management firm that may be responsible for the management of the association while the developer is in control. In Illinois, by way of a 22.1 disclosure, associations are responsible for disclosing financial information, provide full disclosure of pending litigation against the association, provide and manage a budget as well as document and distribute meeting minutes from association meetings ideally held at least quarterly, if not monthly.
I hope that helps shed some light on the situation. Best of luck!
