Promissory note in exchange for a property equity

I had a property with my ex- I agreed to give it up in exchange for a promissory not equaling my share of the equity in the property. Should the note then somehow follow the property? In the case of refinance of the property will the bank then accept the fact the note is following the property if they do not accept a 2nd mortgage? It is a commercial property under an LLC in the state of AZ-the promissory note is part of an MSA in California
