Apna Ghar, Apne Log: A Hypothetical Property Dispute

Bhai, yeh scenario soch lo: Aapka baap 20 saal pehle ek bada ghar khattha chhodta hai aur aaj ka samay hai jab unka loan poora ho gaya hai. Usne ghar ko apne beta ko de diya hai, lekin usme ek shart thi ki jab beta shadi karega, toh ghar uske pita ko wapas milega. Beta shadi karega, lekin kuch saalon me, uska chacha (beta ki ma ka bhai) pehle se hi ghar ki sair karne laga aur ab yeh kaha hai ki vah chacha bade pita bhi hai aur ghar chahega hi uska. TPA mein kya hoga, bhai?
