Bouvier's Law Dictionary, Revised 6th Ed (1856):

COLLATION, descents. A term used in the laws of Louisiana. Collation -of
goods is the supposed or real return to the mass of the succession, which an
heir makes of the property he received in advance of his share or otherwise,
in order that such property may be divided, together with the other effects
of the succession. Civil Code of Lo. art. 1305.
     2. As the object of collation is to equalize the heirs, it follows that
those things are excluded from collation, which the heir acquired by an
onerous title from the ancestor, that is, where he gave a valuable
consideration for them. And upon the same principle, if a co-heir claims no
share of the estate, he is not bound to collate. Qui non vult hereditatem,
non cogitur ad collationem. See Id. art. 1305 to 1367; And @Hotchpot.
