We Help Prevent and Resolve Construction, Condominium Association and Real Estate Development Disputes

Many suppliers, contractors and sub-contractors are honest people who provide materials, complete work and then expect to be paid—sometimes waiting too long, even though they have been promised payment and have a valid contract—And then they aren’t paid or have to fight for payment.

O’Leary Law Firm, LLC helps contractors who have not been paid. We help sub-contractors deep into a project and the contractor was holding back payment.

Many Condominium Association Board members struggle with how to interpret complex rules and regulations, or struggle to repair faulty construction.

Chicago real estate attorney John O’Leary helps associations understand the application and enforcement of rules and regulations or amendments. O’Leary Law Firm, LLC helps condominium associations that have faulty construction.
