Kya Pledge aur Baailment ek hi cheez hai?

Mein aur mera doston ka ek baatcheet raha, juriprudence ka topic tha. Pehla sawal yeh tha - kya Baailment aur Pledge ek hi hain ya nahi? Mein kaha ki nahi, aur yeh kaaran yeh tha ki baailment mein baat kuch time ke liye aur Pledge mein baat life time ke liye hoti hai. Lekin doston ne kaha ki yeh dono hi ek hi cheez hai, jismein owner baaki ke liye kehta hai ki uska property use karo, tabhi koi baati ho.

Lekin mein sochta hoon, kya yeh sach hai?
