This Practice Note, produced in partnership with Peter Levaggi of Charles Russell Speechlys LLP, considers the situation where a borrower/mortgagor with property encumbered by a number of legal mortgages has become insolvent or otherwise defaulted on its obligations. This is a particular problem where the mortgaged property has insufficient value to discharge the total debt. This Practice Note covers the priority of multiple mortgages and remedies available. It includes a look at the principles of marshalling and tacking.
