Effect of registration: company becomes subject to the Act with limited exceptions and pre-registration liabilities attaching. Registration deems existing constitutive provisions and applicable Indian law to be conditions and regulations of the company, and subjects the company, members, contributories and creditors to the Companies Act as if formed under it, subject to exceptions (Table A adoption, share-numbering, restrictions on altering statutory or charter provisions and objects, and Central Government sanction where required). Registration binds persons liable for pre-registration debts as contributories in winding up and preserves conversion and capital-call provisions notwithstanding contrary instrument terms, while prohibiting alteration of memorandum-required provisions not alterable under the Act.
