Hypothetical question

I'm dealing with a situation and need some guidance.

someone copied my website design. I've been dealing with this for about 9 weeks now and the situation isn't improving.

This involves software/code I developed over the past 22 months. I do not have documentation proving my ownership and timeline.

What are my legal options here? Is it worth pursuing?

Fwiw following this thread closely. The amount of practical information here is amazing. Much better than the generic advice I've seen elsewhere.
