3,123. Gifts That the Needy Don't Care About

Hilchos Matnos Aniyim 1:12

So long as a needy person has the right to take olives left on the ground under trees, he may do so; this is true even if permission has already been given to the general public to take shich’cha from the trees. So long as one has the right to take shich’cha from trees, he may do so; this is so even though he doesn’t have the right to take shich’cha from under trees.

Hilchos Matnos Aniyim 1:13

If the needy haven’t shown interest in the gifts from a field, the owner of the field gets to keep them. This is so even if the needy haven’t stopped looking for gifts.
