If
one exchanged a cow for a donkey in a barter exchange and the cow
calved, and the seller says that the cow calved before he sold her, and
therefore the offspring is his, and the buyer says that it calved after
the sale, and the calf is his - they divide the value of the calf.
But
let’s see in whose possession the calf is now - and the burden of proof
would be on the other side! - The cow is in the meadow. But let us
leave it with the original owner - the seller! This ruling is authored
by Sumchos, who always divides the money whose ownership is in doubt.
