Work experience as a partner in father's firm

[Figure07]

Hello friends,

This is a question that i would like to ask regarding the work experience section of the profile.
I have been a partner of my father's firm since a year now.

1. Can this be mentioned as a work experience (with all documents as proof provided wherever necessary)?
2. Which possible NOC level fits best as a partner? (Possibly 0013)
3. Can this be marked as "self-employed" in the self employed checkbox?

Please do let me know..

Thanks in advance...
