If someone wants to challenge a judgment that approves how a succession's money should be paid out (called a tableau of distribution), they have to file a specific type of appeal called a "suspensive appeal." This type of appeal stops the judgment from being carried out while the case is under review. To file it, the person appealing has to follow the bond rules laid out in Article 2124, which means putting up money or security to guarantee the appeal.
While the appeal is going on, the person handling the succession (called the succession representative) can't hand out all the money right away. They have to hold back enough money to cover whatever amount is being disputed in the appeal. This protects the money in case the appeal changes how it should be distributed.
Everything else, meaning any money that isn't tied up in the dispute, can still be paid out. The representative pays the creditors whose claims were approved and aren't being challenged. So the appeal only holds up the disputed portion of the money, not the entire distribution process.
