Black's Law Dictionary
The distinction between a good and a valuable consideration is that the former consists of blood, or of natural love and affection; as when a man grants an estate to a near relation from motives of generosity, prudence, and natural duty; and the latter consists of such a consideration as money, marriage which is to follow, or the like, which the law esteems an equivuient given for the grant.
2 Bl. Comm. 297.
A valuable consideration is a thing of value parted with, or a new obligation assumed, at the time of obtaining a thing, which is a substantial compensation for that which ls obtained thereby. It ls also called simply "value."
