In stipulating participation in acquests, the spouses may adopt any clauses not contrary to articles 1387, 1388 and 1389.
In particular, they may agree to an unequal sharing clause, or stipulate that the survivor of them, or one of them if he or she survives, will be entitled to all the net acquests made by the other.
It may also be agreed between the spouses that whichever of them has a participation claim against the other when the regime is liquidated may demand dation in payment of certain of his or her spouse’s assets, if he or she establishes that he or she has an essential interest in having them awarded to him or her.
