LITIGATION 

Resolution through negotiation,
litigation, and trial

The business litigation attorneys at Lavelle Law are experienced in managing complex matters involving violations of the Illinois Business Corporation Act, the Illinois Limited Liability Company Act and the Uniform Partnership Act, Illinois Trade Secret Act, the Illinois Consumer Fraud Act, as well as cases related to breach of fiduciary duty, fraud, misrepresentation, and other shareholder and member disputes. We represent parties in civil litigation matters such as contract and lease disputes, breach of contract matters, probate litigation, will contests, guardianship estates, employment law matters, and collection cases. Our litigators have trial experience in Illinois and federal courts, administrative hearings and in alternative dispute resolution cases, such as arbitrations and mediations. When urgent issues arise, our commercial and civil litigation attorneys seek entry of permanent injunctions, preliminary injunctions, and temporary restraining orders to protect your interests immediately. We also frequently act as local counsel for attorneys that are not based in Illinois but have clients with litigation pending in federal or state court in Illinois.
