I\'m not quite sure what your asking but I\'ve interpreted it the best I can .
If no-one is at home , I believe they have the right to leave your parcel [Assuming you have a letterbox , it just doesn\'t fit] with someone around say a neighbour aslong as they sign for it . They have no legal obligation to wait for someone to come to the door/or wait for you to return - otherwise mail would never get delievered .
However if they are just \'dumping\' it , then I believe that to be negligence on their part and you could probably pursue a claim - especially if the parcel contained personal information .
Surely if the parcel hasn\'t been delievered they leave a card saying where it is ? At least that what happens in my area .
