A partnership firm can indeed be dissolved even many years after the business has ceased trading, provided a dissolution deed wasn't created at the time of closure. The dissolution can be executed by mutual consent of all partners or as per the original partnership agreement. If the partnership deed was registered, the partners can now formalise the dissolution, specifying the original closure date. It's important to note that simply shutting down a business doesn't automatically dissolve the partnership; statutory liabilities continue until formal dissolution and closure of associated accounts and PAN.
