I assume you meant to write "petition" and not partition (partition is a separate remedy from a receiver).
If you don't want to pay a lawyer, then you need to review your state statutes, review your rules of procedure, draft the complaint, serve the complaint and summons and follow all the rules of procedure and evidence to the letter.So go to a local law library and start reading. Also go to nolo.com for general resources. Good luck.
