Roof Rights, Common Expenses In Builder Floor & Fake Promises

Q.1 Builder floor me 4 floor hein. Koi agreement nhi he common expenses share karne ka. Agar koi floor owner lift AMC or electricity bill pay karne se mana kar de pr fir bhi lift use kare or apne floor pr lift ka button bhi band na karvane de. *Is case me agar hm uske floor pr lift band karte hein or vo court case karta he hm pr to kya hme charges lgenge? * AMC charges hamne pay kiye hein pr lift license other floor owner ke naam he jo AMC nhi pay kar ra. Kya hm lift band kar sakte hein legally uske floor pr ?
