I wrote a contract with my ex for stuff he broke during a domestic violence incident. In lieu of a domestic violence suit, I told him to just pay me back for the damages and that if he didn't pay me back I'd take him to court both for the damages and the domestic violence. After receiving some crucial legal advice, I learned that adding the part to the contract about filing a domestic violence suit if he didn't pay is extortion and wouldn't look good on my part in court. Is it ok for me to just nullify that part of the contract after we've both signed it? Can I just get us both to agree to nullify that part or do we need to redo the contract all together?
