Short answer. Only for enforceability against third persons. An unregistered real estate mortgage is still binding between the lender and the borrower who signed it, but recording in the Registry of Property is what makes the mortgage a charge on the land that binds later buyers and other creditors.
What the law says
it is indispensable, in order that a mortgage may be validly constituted, that the document in which it appears be recorded in the Registry of Property. If the instrument is not recorded, the mortgage is nevertheless binding between the parties.

What recording actually accomplishes
The article puts it in strong terms: it is indispensable, in order that a mortgage may be validly constituted, that the document in which it appears be recorded in the Registry of Property. Read on its own, that sounds as though an unrecorded mortgage is nothing at all. The sentence that follows corrects the impression. Recording is what perfects the mortgage as a real right — a charge that travels with the land itself rather than a promise owed by one person to another. Until the deed is annotated on the certificate of title, the lender holds a contract, not a lien the rest of the world has to respect.
Between the two of you it binds regardless
If the instrument is not recorded, the mortgage is nevertheless binding between the parties. A borrower who signed a mortgage cannot walk away from it by pointing out that the lender never went to the registry. The obligation to pay stands and so does the agreement to secure it. What the lender loses is priority and reach: a later buyer who takes the title in good faith, or another creditor who registers first, is not bound by a charge that never appeared on the certificate. That gap between the parties and the wider world is the whole subject of the provision.
Mortgages the law itself creates
The closing sentence deals with security interests that arise by operation of law rather than by negotiation. Those beneficiaries have no other right than to demand the execution and the recording of the document in which the mortgage is formalized. A legal mortgage, in other words, does not appear on the title by itself. The person entitled to it must obtain the instrument and have it recorded, and until that happens he stands exactly where any unrecorded mortgagee stands. It is the same lesson stated from the other direction: recording is the act that gives a security interest its effect against strangers to the deal.
Which document settles the question
The answer for any particular property is on the title, not in the loan papers. If you are the lender, the mortgage should appear as an annotation with a date on the registry's own copy of the certificate. If you are the borrower, that same annotation is what a prospective buyer will see. And if you are buying, a clean title is not proof that no mortgage was ever signed — it means only that an unrecorded one cannot be enforced against you if you buy in good faith and for value, which is narrower comfort than it sounds. Work from the registry copy rather than from a photocopy of the deed.
