Moussier managed the plantation until he died at home in New Orleans on June 11, 1831.
Moussier died heavily in debt. When an inventory was done on Grande-Terre Plantation after his death, Moussier's 61 slaves were assessed with a total value of $21,905.00.
The majority of the plantation and Moussier's slaves were purchased by the Consolidated Association of the Planters of Louisiana to clear Moussier's debts.
The remainder of the plantation's slaves were purchased by the Moussier family. In 1841, the island was bought by the U.S. government to construct
Fort Livingston.
Due to Moussier's respect in his community, in 1836, Citizens' Bank of New Orleans, a bank that had not existed when Moussier was alive, issued "a sum of $2500" to provide for the welfare of Moussier's daughters who by that time were living in a destitute situation.
