(1) Where a person becomes entitled by assignment or transmission to a registered layout-design, he shall apply in the prescribed manner to the Registrar to register his title, and the Registrar shall, on receipt of the application and on proof of his title to his satisfaction, register him as the proprietor of the layout-design and shall cause particulars of the assignment or transmission to be entered on the register:
Provided that where the validity of an assignment of transmission is in dispute between the parties, the Registrar may refuse to register the assignment or transmission until the rights of the party have been determined by a competent court.
(2) Except for the purpose of an application before the Registrar under sub-section (1) or an appeal from an order thereon, or an application under section 30 or an appeal from an order thereon, a document or instrument in respect of which no entry has been made in the register in accordance with sub-section (1), shall not be admitted in evidence by the Registrar or the Appellate Board or any court in proof of title to the layout-design by assignment or transmission unless the Registrar or the Appellate Board or the court, as the case may be, otherwise directs.
