The original property is valued according to its condition on the day of the marriage or acquisition, and according to its value on the day the matrimonial property regime is liquidated. If they have been alienated, their value on the day of alienation is taken. If new assets have been subrogated to the alienated assets, the value of these new assets is taken into consideration.
From the original assets are deducted the debts to which they were encumbered, revalued, if necessary, according to the rules of article 1469, third paragraph. If the liabilities exceed the assets, this surplus is fictitiously reunited with the final estate.
