Here is the Legal term for donation/gift
Donations are gifts given without return consideration. This lack of return consideration means that, in common law, an agreement to make a donation is an "imperfect contract void for want of consideration."[1] Only when the donation is actually made does it acquire legal status as a transfer or property.[citation needed] In civil law jurisdictions, on the contrary, donations are valid contracts, though they may require some extra formalities, such as being done in writing. Gifts "May Not Under Any Circumstances" Be Exchanged for any form of but not limited to cash, services, new or used goods including clothing, toys, food, vehicles etc.,.,. If Such is exchanged For the right to Own a "Gift" Then this contract becomes void.
There you go that pretty much somes it up.
