I was in the similar position where I built the tech and the co-founder had the idea. The bottom line is that whether you sign the contract or not, if you have gotten compensated for your work through shares or money, then the IP is owned by the company.

If you think your co-founder is going to take you to court, then don't do it. I learned my lesson that fighting it in the court is expensive and useless. Only person that is going to win would be the lawyer. You are never going to get an investor with a pending lawsuit. Every bit of money you are going to earn, you will spend it on the lawyers and its not cheap. Whether you are right or wrong, the lawyer needs to prove it. Sometimes they can have legitimate case sometimes they don't. But it doesn't matter...it will take years before it get settled. Until then you will be living off of whatever you got left from the lawyer's fees.

I have been there. Not worth it.
