A buyer pays 900 of 1000 zuz for a field. The seller repeatedly demands the remaining 100. Did the buyer acquire the field?
When a seller repeatedly pursues the remaining balance, it signals that he never concluded his intent to sell. The buyer does not acquire the full field regardless of partial payment or deed-writing.
Question 2
The seller retracts after the buyer paid half the price. What are the buyer's options?
When the seller retracts, the buyer is given the 'upper hand' — he can either demand a refund or take the best portion of land equivalent in value to his payment.
Question 3
A field worth 100 was sold for 200. The seller demands the balance repeatedly. Can either party retract?
This is a case of doubt: was he demanding because he didn't complete the sale, or because he sold at an overvalue? Because it's unresolved, neither party can retract. If the seller seizes property equal to unpaid funds, it is not extracted from him.
Question 4
Reuven tells Shimon: 'If I sell this field, consider it sold to you from now for 100 zuz' — and Shimon performs kinyan. Later Reuven sells to Levi for 150 zuz. Who acquires the field?
When the field is sold for more than the agreed pre-sale price, it's considered that Reuven was 'pushed' into selling by the extra money — as if compelled. The first buyer's pre-sale right does not cover a price he never agreed to. Levi acquires.
Question 5
A buyer paid 90 instead of the agreed 100 due to miscounting. Years later the seller discovers and claims the difference. What is the ruling?
A payment error does not void the kinyan. The transaction stands and the buyer owes the unpaid balance as a regular debt — even if the discrepancy is discovered years later.
