Specialization
Chance specializes in civil transactions and lawsuits. With transactions, Chance advises individuals on simple and complex civil matters including early business startups and intellectual property protection; family disputes, domestic violence, temporary restraining orders, and pre-marital considerations. Chance also helps enterprises with entity formation, agreement preparation, copyright and trademark registration and enforcement, labor and employment disputes, and regulatory compliance.
Chance's lengthy litigation experience compliments his transactional practice. Prosecuting and defending all stages of hundreds of lawsuits has helped him create legal strategy for his clients. He knows how important it is to avoid pitfalls by preserving critical evidence and always maintaining a strong negotiating leverage. A strong pre-litigation strategy ultimately saves his clients time and money.
Previously, Chance litigated complex cases with emphasis on commercial, banking, real estate, construction defect, intellectual property, and products liability. Chance has represented a wide variety of individual and corporate clients in federal, state, appellate courts, and before JAMS/American Arbitration Association (AAA). He helps his clients successfully navigate all facets of civil litigation, including pre-litigation analysis of key legal and factual issues; discovery; trial; pre/post-trial motions; and settlement negotiations and mediations.
