Before you start get legal
 

What would be your first step's, Before contacting a lawyer?

huh?

what do you mean before you get "legal" and in what term? before you contact an attorney for adult biz related or just life in general?

make sure you have enough money?

Write a demand letter or a C&D depending on what the hell you are getting legal about. Slap it on some official letterhead (or an attorney's letterhead) and send it off. Most things settle out of court as soon as it gets serious.
