Signing, Paying, and Registering Are Not the Same
It is common to think the process ends the day you sign at the notary’s office. It does not. Signing, paying, and being registered are three separate moments, and only the last one protects you against third parties. The signed deed gives you a valid document between you and the seller, but as long as it is not registered with the Instituto Registral y Catastral del Estado de Nuevo León (IRCNL), a third party acting in good faith could in theory register a right over the same property before you do. That is why the notary does not consider a file closed until the registration is reflected, not just the signature.
The Step-by-Step Process
The typical order, although it may vary depending on the notary and the complexity of the case:
1. Choice of notary. By custom, the buyer proposes one, although it is negotiable.
2. Commercial appraisal. This is done by an authorized appraiser. It serves as a reference to calculate the ISAI and to give the notary a documented market value, in addition to the cadastral value.
3. Certificate of no liens. The notary requests it from the IRCNL to confirm that the property has no mortgages, liens, or current precautionary annotations.
4. Payment of ISAI (Impuesto Sobre Adquisición de Inmuebles), which is paid to the corresponding municipal treasury before or at the time of signing, as instructed by the notary.
5. Signing of the deed before the notary, once identifications, RFC, proof of payment of property tax and water, and the rest of the file’s documents have been gathered.
6. Payment of registry fees to the IRCNL to begin the registration process.
7. Final registration. The IRCNL reviews the document and records it; this is where the property is formally placed in your name against third parties.
The time between signing and registration is not immediate: it depends on the IRCNL’s workload and on whether the file is complete or requires corrections.
Who Pays What, by Custom
There is no law that divides the costs; it is defined by market custom and can be negotiated in the purchase offer. What is usual in Nuevo León:
- The buyer usually covers notary fees, ISAI, and registry fees, because the buyer is the one who receives the direct benefit of the registration.
- The seller usually takes care, at their own expense, of any lien, encumbrance, or property tax debt from before the sale, in order to deliver the property free and clear.
- Taxes on the gain from the transaction (when they apply) are the responsibility of the person who sold, but the calculation depends on the case and it is best to review it directly with the notary rather than assume it.
If any of this is not clear in writing before signing, it is the most common source of last-minute friction.
What Delays a Deed Transfer
In practice, what most lengthens the process is not the process itself, but what is missing before reaching the notary:
- Incomplete or outdated documents (identifications, certificates, RFC, proof of payment).
- Liens or annotations that appear in the certificate of no liens and that no one had resolved.
- Property tax or water debts that the seller had not paid.
- Differences between the measurements and boundaries of the property and what the cadastre has registered, something more common on rural land than in urban areas.
- IRCNL response times, which vary depending on the institute’s workload and are not under the control of the notary or the parties.
Arriving with the complete file from the start is what shortens the process the most; improvising along the way is what lengthens it the most.
