In short
The Civil Code devotes six articles to the mortgage, and it is worth knowing from the outset how far they reach. It defines it as a real security right that may be constituted over immovables which remain in the hands of the debtor or of a third party, to secure any kind of obligation: that is exactly the difference from the pledge, where the asset is handed over. Immovables and the transferable real rights imposed on them may be the object of a mortgage. Mortgages are voluntary or legal, and legal ones are those for which the law grants a right to demand their constitution. The weightiest rule is in Article 1014: for the mortgage to be validly constituted it is indispensable that the instrument constituting it be recorded in the Property Registry, except where the law recognizes it as tacit; here recording is not publicity, it is validity. The mortgage credit may be transferred or assigned to a third party in whole or in part, with the formalities the law requires. And Article 1016 closes the chapter by referring everything else — the form, extent and effects of the mortgage, and its constitution, modification and extinction — to the real-property registry legislation.
What is it?
It is Chapter III of Title VII of Book Three of the Civil Code of 2020, Articles 1011 to 1016. Six articles: they set what a mortgage is and what makes it valid, and refer the rest to the real-property registry legislation.
Who can do it?
It may be constituted over immovables and over the transferable real rights imposed on them. The asset remains in the hands of the debtor or of a third party. As with any real guarantee, it may be constituted by the debtor or by a third party over their own assets.

Step by step
Step 1: What it is, and how it differs from the pledge
Article 1011 defines it as a real security right that may be constituted over immovables which remain in the hands of the debtor or of a third party, to secure any kind of obligation. The phrase that makes the difference is "which remain in the hands of the debtor": in a pledge the asset is handed over, in a mortgage it is not. That is why you can go on living in a mortgaged house.
Step 2: What it can fall on
Article 1012 delimits it: immovables and the transferable real rights imposed on those assets may be the object of a mortgage. Not only the land: also, for example, a transferable real right burdening it.
Step 3: Voluntary and legal
Article 1013 splits them in two: mortgages are voluntary or legal, and legal ones are those for which the law grants a right to demand their constitution. The Code neither lists them nor names the statutes; nor does this guide, because we did not read them.
Step 4: Without recording there is no mortgage
Article 1014 is the most important of the six: for the mortgage to be validly constituted it is indispensable that the instrument constituting it be recorded in the Property Registry, except where the law recognizes it as tacit. In other rights recording serves to assert the right against third parties; here it is a requirement of validity. A mortgage signed and not recorded is not a mortgage, save for the tacit ones the law recognizes.
Step 5: The credit can be sold
Article 1015 allows it in one line: the mortgage credit may be transferred or assigned to a third party in whole or in part, with the formalities the law requires. A bank selling your loan to another entity is a possibility the Code expressly contemplates.
Step 6: And everything else is not here
Article 1016 says it plainly: the form, extent and effects of the mortgage, as well as its constitution, modification and extinction, and everything else not regulated in this chapter, are governed by the real-property registry legislation. That is, almost everything a mortgage borrower needs to know lives outside the Civil Code. This guide did not read it and therefore does not summarize it.
Step 7: What does apply: the title’s common rules
Though this chapter is short, the mortgage is a real security right and the general provisions of Chapter I reach it. Among them, the one that most protects the debtor: the creditor may not appropriate or dispose of the encumbered asset except by acquiring it through the corresponding execution, and any agreement to the contrary is null and treated as unwritten. Also indivisibility, real subrogation onto whatever replaces the asset, and the prohibition on the owner doing acts that diminish the guarantee’s value.
Where to do it
Before a notary for the instrument, and before the Property Registry for the recording Article 1014 makes indispensable for the mortgage to be validly constituted.
How long it takes
What to do if something goes wrong
If what you face is a foreclosure or you want to negotiate with the bank, this chapter is not your tool: we have separate guides on compulsory mediation and on loss-mitigation alternatives. If the asset is movable, the figure is the pledge. And if what you are after is the form, extent, effects, constitution, modification or extinction of the mortgage, Article 1016 sends those to the real-property registry legislation, which we did not read: this guide neither summarizes nor interprets it. Nor does it say which mortgages are legal ones or in what cases the law recognizes a tacit mortgage, because the Code does not say so here. The Code publishes no fee and no term, so this guide gives none. MiPRFácil does not represent anyone in court and gives no legal advice.
Common mistakes
- Believing signing the deed is enough: without recording it is not validly constituted, save a tacit mortgage recognized by law.
- Thinking a mortgage means handing over the property: the asset remains with the debtor or a third party.
- Assuming only the land can be mortgaged: so can the transferable real rights imposed on it.
- Taking for granted that the creditor cannot sell your loan: the mortgage credit may be assigned in whole or in part.
- Looking in the Civil Code for the mortgage’s effects and extinction: Article 1016 sends them to registry law.
- Signing that the bank keeps the house without a foreclosure: that agreement is null under Article 998.
Frequently asked questions
Is an unrecorded mortgage valid?
Article 1014 says that for it to be validly constituted it is indispensable that the instrument be recorded in the Property Registry, except where the law recognizes it as tacit. Here recording is not publicity: it is validity.
Must I hand the house over to the creditor?
No. A mortgage is constituted over immovables which remain in the hands of the debtor or of a third party. That is the difference from the pledge.
Can my mortgage loan be sold?
Yes. Article 1015 allows transferring or assigning the mortgage credit to a third party in whole or in part, with the formalities the law requires.
Where is the rest about mortgages?
In the real-property registry legislation. Article 1016 refers to it the form, extent and effects of the mortgage, and its constitution, modification and extinction. This guide did not read it and does not summarize it.

Putting an asset up as security for a debt: the common rules
The creditor may not keep the asset outside an execution, and any agreement saying otherwise is null and treated as unwritten.
The pledge: leaving a movable asset as security for a debt
The creditor retains it until paid and may not use it without permission. To sell it: a notary, a public auction and summons to the debtor.
Antichresis: paying the debt with a property’s fruits
The creditor collects from the fruits and in exchange pays taxes, conserves the property and renders accounts. But they may hand it back whenever they wish.
Mortgage foreclosure: the mandatory mediation the court cannot skip
If they sue to foreclose on your principal residence, mediation is a jurisdictional requirement: without it no judgment can be entered and no judicial sale held.
Loss mitigation before you lose the house
Act 169-2016 bars the creditor from starting collection once it receives your loss-mitigation request, and forbids refusing partial payments.
