What is the halacha if I break your toy. I buy you the same toy as I broke but who keeps the “broken” toy?
The halacha is the the one who broke the toy has to pay the difference between the toy’s value before and after it was broken. this is because the owner of the toy keeps the broken toy and it’s present value in his. By the way if the toy was used it’s original value was only the value of a used toy.
