Difference Btw Maintenance and Alimony: Maine Confused Ho Gaya

Yaar samajh nahi aaya, please help! Maine contract subject fail kiya tha, lekin ab family law se struggul hai. Maine socha tha maintenance and alimony dono ke liye kuch hi alag hi hain, lekin now yaar dono hi similar lage hain. Maine padha hai ki maintenance wala concept 125th Amendment ke under aata hai, aur alimony wala 89th Amendment ke under. Ab kya hoga agar couple marriage se jud kar rahe hain, lekin kuch bhi earn nahi kar rahe hain? Dono hi maintenance ke liye court ka option hai? Maine samjh nahi aaya koi aisa difference kya hai? Please help kare, aapko to samajh hai, yaar!
