Which of the following documents is needed only after the liquidation of the succession?

The Delivery of Legacy is the document that is needed only after the liquidation of the succession because it pertains to the distribution of the estate's assets to the heirs once all debts and obligations have been settled. This process of liquidation involves evaluating the estate's assets and liabilities, and only after this step can the heirs receive their respective legacies.

In contrast, the Declaration of Transmission is necessary to officially transfer property ownership to heirs, and this can occur even before the final liquidation process is complete. The Act of Nomination typically refers to the appointment of an executor or administrator for the estate, which is also required prior to the liquidation. Lastly, a Notarized Will is crucial for establishing the terms of the succession but does not specifically relate to the liquidation process itself. The focus of the Delivery of Legacy on the distribution stage emphasizes its role as a concluding step following the liquidation of the succession.
