Does the Illinois condominium act supersede an association's own condo docs?

Your question exceeds the level of accuracy that WikiAnswers can provide in this case, because you haven't given us the details.

Generally, the state condominium law supersedes a community's governing documents when the docs don't address a specific issue and the state law addresses it. Otherwise, the state law simply serves as a guideline -- a template -- to the developer and the attorney who craft the community's docs.

However, where the two are different, you may need the advice and guidance from an attorney who specializes in condominium law to help you determine that your association's docs are invalid and unenforceable in light of the state condominium law.

For example: If the state law reads that "except as provided by the declaration the unit boundaries are drawn at the studs" and your docs read that "the unit boundaries are drawn at the paint/ wallcovering", the condo documents may prevail.

In your case, best practices indicate that you pay for professional advice.
