This guide covers business insolvency from the first cash forecast through plan confirmation or wind-down. It begins with the choice among chapters and alternatives, then explains the automatic stay and what it does and does not reach. A full part covers Chapter 11 mechanics: first-day motions, cash collateral, debtor-in-possession financing, professional retention, operating requirements, and the streamlined small-business track. Separate parts address executory contracts and leases, the avoidance actions that recover value for the estate, the priority scheme that determines every negotiation, and the plan process from classification through confirmation and discharge. Further parts cover section 363 sales, the alternatives to bankruptcy, the creditor's perspective including preference defense and claim protection, jurisdiction and venue, and the personal exposure of owners, officers, and directors. The guide closes with special situations, worked problems, and a reference section. Authority is cited and linked throughout.
