The Salic Law outlines a unique way of securing the payment of money owed. It is called the Chrenecruda (or crenecruda, chren ceude, crinnecruda). In cases where the debtor could not pay back a loan in full they were forced to clear out everything from their home. If the debt still could not be paid off the owner could collect dust from all four corners of the house and cross the threshold. The debtor then turned and face the house with their next of kin gathered behind them. The debtor threw the dust over their shoulder. The person (or persons) that the dust fell upon was then responsible for the payment of the debt. The process continued through the family until the debt was paid.
