In contracts there is a need for Consideration (legal term).
There are 2 types of Consideration, one is something like cash, or something that can be converted to cash easily. The other type of Consideraion is a little less defined,,, BUT A LOT MORE VALUABLE!
Consideration can be in the form of Love, or Luv, or Appreciation, or Just Because,,,, to Loved Ones and Cherished Ones, and Family or Friends, or ETC.
I think that is what you are referring to.
A good search of Valuable Consideration With Legal Contracts on one of the search engines on the internet may give you a good anwer.
