Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

client reselling my photography. I've been dealing with this for about 10 weeks now and the situation isn't improving.

This involves software/code I developed over the past 18 months. I do have documentation proving my ownership and timeline.

Illustrative response
