I am looking for a good translation in English. So I went to http://www.wordreference.com/ , clicked on French to English and the word "hypothecaire".

Got the following results:

hypothécaire:
hypothécaire adj  hypothecary
 
Compound Forms:
acte d'obligation hypothécaire nm mortgage deed
acte hypothécaire mortgage deed
créancier hypothécaire mortgage holder
créancier hypothécaire nm mortgage-holder
obligation hypothécaire à payer nf mortgage bond
société de crédit hypothécaire mortgage company
société de prêt hypothécaire mortgage company

 

As the result, I am coming up with Mortgage deeds & registration fees...to convey the fact that the fees do not only cover the mortgage deeds but also the fact that is a registered mortgage.
