Regulator No Objection Certificate requirement: obtain regulator NOC at incorporation and for LLP name changes. Approval of the professional council or regulator, in the form of a No Objection Certificate (NOC) or in principle approval, must be obtained at the time of application for incorporation or conversion into an LLP where the LLP will carry on regulated professions. For change of name of an existing LLP, the regulator's NOC must be obtained when applying for name approval because the name change is effected through a specific statutory filing route processed in a streamlined mode.
