Where the market price of the mortgaged item decreases and becomes insufficient to secure the debt, the creditor may fix a suitable time limit for the mortgagor to complement the security. If the mortgagor refuses the same or where the fixed time limit expires and the mortgagor fails to complement the security, the creditor may cause the item mortgaged to be sold, even before the maturity date, by adopting the procedures stipulated in Article (170) above.
