These forms are used by a prospective junior lender or carryback seller when the real estate is encumbered by an existing first mortgage containing a due-on clause, to obtain consent from the lender holding the mortgage to further encumber the property with a second mortgage, and by a loan broker or escrow officer when originating a mortgage with the lender or carryback seller, to include a guarantee, exculpatory or governing law provision in the promissory note.
