A buyer places his container in the seller's domain. The seller pours goods into it without further instruction. Are the goods acquired?
A buyer's container does not acquire goods in the seller's domain unless the seller explicitly said 'go acquire with this vessel.' Otherwise the goods remain the seller's.
Question 2
In which location does mesirah (handover) work as an acquisition method?
Mesirah is effective only in the public domain or in a neutral courtyard. In the public domain, mesirah replaces meshichah since pulling a large object there is impractical.
Question 3
A seller prices produce at 30 sela per kor and measures into his own vessel in the buyer's courtyard. Can he retract before finishing?
The seller's vessel does not acquire for the buyer even in the buyer's domain. Since the measure isn't complete and the vessel is the seller's, the seller may retract up to the last seah.
Question 4
A buyer lifts an item to inspect it. The item has a fixed, well-known market price. The seller then demands the price. Is the buyer obligated?
When an item has a fixed, known price and the buyer lifts it with intent to purchase, acquisition occurs at that moment — even if the price discussion follows afterward.
Question 5
A price is agreed upon, then the buyer lifts the goods. Later it's discovered he paid 90 instead of the agreed 100. Is the transaction valid?
A mistaken payment amount does not void the sale. The kinyan stands, and the buyer must make up the shortfall — even years later. This applies to both land and movables.
