Section 62 TPA ka Maze: Is it just me?

Main to abhi tak kheenchaa raha hoon, lekin section 62 TPA kaafi confusing hai. Yeh section kehta hai ki jab landlord tenant se koi rent nahi leti hai to woh bhi apni property ka khud se adhikar le sakta hai. Lekin yeh rahi baat, property ka adhikar kis tarah se milta hai? Kya bas usne kuch rent di hai to voh mil jaata hai? Yeh sawal kaafi confusing hai. Phir yeh bhi hai, section 108 mein kaha gaya hai ki landlord tenant ko notice bhejne se pehle property ka adhikar nahin le sakta hai. To yeh section 62 kaafi contradictory laga raha hai.
