A field sold as 'a beit kor' contains a single large rock (beit rova lekor). Is the rock measured as part of the field?
A single large rock — even one the size of a quarter-kav for the entire kor — is never measured with the field. If it touches the boundary of the field, even a very small rock is excluded.
Question 2
A seller says 'I am selling you a beit kor measured with a rope.' The measured parcel turns out to be slightly smaller. What happens?
Adding 'measured with a rope' makes the transaction exact. Any deficiency, even the smallest, requires a proportional price reduction. The quarter-kav tolerance applies only to 'beit kor' sales without the rope measurement clause.
Question 3
A field is sold as 'approximately a beit kor.' It turns out to be one-fourth kav short per se'ah (1/24 deficiency). Must the seller compensate?
A deficiency of one-fourth kav per se'ah (1/24 of the total) is within the tolerance zone for approximate sales. This variation is forgiven and neither party can demand adjustment.
Question 4
A parcel sold as 'beit kor' has a surplus of 10 kabbim. The seller wants the land back. The land has risen in value since the sale. What must the buyer return?
When land rose in value, the buyer returns the surplus land at purchase-time proportional price or gives money at the sale price. When the land fell in value, the buyer can choose to return money at the original price or land at current value.
Question 5
A seller says 'I am selling you this beit kor' pointing to a known parcel. The actual measurement is only a letch (half a kor). Is the sale valid?
When a specific, named location is sold ('this beit kor'), the sale is for that named place — not for a precise measurement. The seller must prove it is indeed called 'beit kor,' but if so, the sale stands even if the actual area is smaller.
