Registered office requirement imposes duty to maintain address and notify Registrar; failure to comply attracts prescribed penalties. Every limited liability partnership must maintain a registered office for receipt of communications and may specify other addresses for service; documents may be served by post or other prescribed means at the registered office or a declared address. Changes to the registered office require filing notice with the Registrar in the prescribed form and conditions and take effect only upon such filing. Noncompliance attracts penalties as prescribed under the statute.
