English to Arabic Law/Patents Law: Patents, Trademarks, Copyright Certificate of Police Record

Dear Colleagues,

Greetings

What would be the best translation for the term SUBSCRIBED into Arabic in the following text:

On ...... , before me, ...... , Notary Public, personally appeared ......., who proved to me on the basis of satisfactory evidence to be the person whose name is subscribed to the within instrument, and acknowledged to me ...

I appreciate any explanation you provide.

I was thinking of translating it as :
التي يظهر اسمها داخل الوثيقة
What do you think? Is it correct?

Thank you for your help!
