In a mortgage, a provision that allows part of the security to be released from any
further lien obligations upon the borrower's making a given payment. For example, a person may get a
blanket mortgage for real estate having several structures. The mortgage may have a release
provision in it allowing individual structures to be released from any later mortgage obligations
when the mortgagor receives a payment from the mortgagee, either through sale of the structure or
because of the payment.
