Jonathan Sundheimer’s practice runs the spectrum of lending, bankruptcy, commercial litigation and loan restructuring. He documents loan transactions on behalf of financial institutions, and represents such institutions in the event of default through negotiations and litigation. Beyond financial institutions, he guides businesses through collections, bankruptcy and insolvency-related dispute resolution.

Simply put, Jonathan counsels businesses and individuals that loan money or are owed money. On the front-end of lending relationships, Jonathan has experience representing banks, both large and small, with loan originations, extensions, modifications and amendments. He has advised banks regarding loan participations, subordination agreements and mezzanine financing.

On the back-end of lending relationships, Jonathan has experience enforcing commercial real estate loans, representing receivers and collecting judgments. He regularly represents special servicers and financial institutions throughout Indiana in negotiating loan modifications and loan enforcement. In bankruptcy, he has represented creditors in all aspects of Chapter 11 proceedings, including cash collateral disputes, 363 sales and plan confirmations.

In both bankruptcy and commercial litigation, Jonathan’s work has led to published opinions in Indiana state and federal courts, the Indiana Court of Appeals and the U.S. Court of Appeals for the Seventh Circuit. Out of court, he has helped restructure loans secured by real property, rents and equipment.

Jonathan has frequently advised manufacturing clients on strategies for minimizing risk in the supply chain. His advice has helped both suppliers and original equipment manufacturers avoid assembly line shutdowns and ensure continuing operations. Whether negotiating contract terms or seeking the appointment of a receiver over a supplier’s operations, Jonathan’s work has reduced losses when sole source suppliers go dark.

Jonathan is a frequent speaker, and has presented to the National Association of Credit Managers, Indianapolis Bar Association’s Leonard H. Opperman Chapter 11 Roundtable, ICLEF Annual Bankruptcy Institute, and the Building Owners and Managers Association.

Dedicated to direct and clear communication, Jonathan is at his best when faced with the fast pace, obstacles, complexity and diversity of legal representation involving lending and collections. Whether he is in or out of court, Jonathan is appreciated by clients and colleagues alike for being practical and reasonable, and for providing a realistic assessment of each client’s options and how that path could support their end game.
