A dispute as to volume of indebtedness is not a valid ground known to law such as can be relied upon to prohibit a mortgagee from exercising his right of sale. In other words, the mortgagee will not be restrained from exercising his power of sale because the amount due is in dispute. He will be restrained, however, if the mortgagor pays the amount claimed into court, that is the amount which the mortgagee swears to be due to him, unless on the terms of the mortgage the claim is exclusive.
