Banks and Financial Institutions can indeed file recovery suits for Non-Performing Asset (NPA) accounts. For amounts between £300,000 and £1,000,000, Commercial Courts may be an option, while amounts exceeding £1,000,000 typically fall under the Debt Recovery Tribunal (DRT). However, it's crucial to note that a simple money recovery suit isn't automatically a commercial dispute; the nature of the transaction, involving mercantile documents and a business context, determines eligibility for the Commercial Courts Act.
