Kya Hoga Agar Main Contract Ko Fail Karunga?

3 din mein exam, par yeh ek cheez main aaj bhi samajh nahin a rahi. Wahi wahi, par performance guarantee ka topic hai. To kya hoga agar aapne ek contract sign kiya aur wo guarantee provide nahin karta, lekin phir bhi aapko loss pahunch jata hai? Kya uska dhancha valid rah sakta hai? Main to aaj tak uski validity ka samajh nahin pa raha. Wahi baat ek dusri cheez hai, kya aap performance guarantee ko specific performance ke naam par cancel kar sakte hain ya nahin? Bas yahi kuch soch raha hoon, par kuch bhi nahin samajh raha. Koi bhaiya help karega?
