My Ex-wife and I got married in China in 2001 and got divorced in China in 2005. We do not have any children. I signed an agreement to pay her lifelong alimony when we filed for divorce in China. Now both of us are US Citizens. Now I don’t think paying a lifelong alimony is fair to me and I want to change it. Is it possible? I do not think she wants to accept any change. If it can be done, can it be done at NC or I have to go back to China? If I do it in NC, do I need to go to a court?
