Path B: the Article 4.012A summary procedure and the housing priority, step by step

Path B is the reverse of Path A. There is no letter of intent here, no deposit from you, and you do not decide when it starts: the summary expropriation procedure of Article 4.012A is initiated by the municipality on its own, with judicial deadlines measured in days.¹ Act 114-2024 (July 2024) added it and Act 97-2026 (June 2026) amended it, and it carries the most important rule for anyone seeking housing: a first purchase option, during the first year, for people with limited access to the traditional market.

If you are new to the topic, the recommended order is what a public nuisance is, then the overview of the acquisition paths, and this guide for the summary track detail.

The idea in one minute

When a property is declared a public nuisance, one effect is that the municipality may expropriate it; Article 4.010(d) expressly mentions the summary procedure route.⁴² If the municipality picks that route, it sues in court on a compressed calendar, obtains the property, and then sells it under a municipal ordinance that must give priority to a specific buyer profile when the property can become a residence again. Your role as a citizen is not to start the process: it is to position yourself for the sale that comes after.

The summary lawsuit, day by day

This is how the judicial clock runs once the municipality files the complaint under Rule 58, which applies in a supplementary way:

Compare that with Path A's ordinary lawsuit, which can take up to a year: here a case with no opposition can be resolved in weeks.

The money on the municipal side (and the owner's)

The municipality is not required to deposit money when filing the complaint; the obligation begins when the defendants appear through their answer.⁸ And if the defendant appears, only the property taxes owed and the fines and cleanup and maintenance costs incurred by the municipality may be deducted from the just compensation (Art. 4.010).³⁹

For the owner there is one final clock: once the judgment sets the just compensation, anyone entitled to it has three (3) years to claim it; after that, the action prescribes (Art. 4.012A(g)).¹⁰

The housing priority: how the calendar works

The final paragraph of Article 4.012A is the most important part of this path for the citizen. When it comes to built properties that can be rehabilitated as residences, the municipality must consider as a first option, when there are interested citizens, the people whose opportunity to acquire a property is limited in traditional market processes.¹¹ The complete calendar, counted from the nuisance declaration:

• Year 1 from the declaration: people with limited access to the traditional market are not considered third-party acquirers. That is their priority window, under the ordinance adopted pursuant to the article itself.
• One year to secure funds: the interested citizen is granted one (1) year to secure the funds, aid, or any other available method to satisfy the just compensation and associated costs, with a possible additional six (6) month extension.¹²
• Once the full term lapses without a purchase: the municipality may sell to third-party acquirers, including real estate market investors.
• And if no one shows up: after one (1) year from the declaration and inventory listing without anyone showing interest,¹³ the municipality may dispose of the property under the article.

What exactly does limited access to the traditional market mean? The law does not define it: the concrete criteria are set by each municipality's transfer ordinance. Some already built it into their nuisance regulations; get your municipality's before claiming the priority.

The exclusion of investors

The article is categorical: the summary mechanism shall not be used to benefit third-party acquirers, including those recognized as real estate market investors. A third-party acquirer is someone who holds no legitimate property right, unlike an heir or record owner. The first-year exception¹⁴ exists solely for people with limited market access, who during that period do not count as third parties.

How to position yourself (it is not a letter)

Here is the most common confusion: on this path you do not file the Article 4.012 letter of intent. That does not mean sitting on your hands:

• Identify the declared property at estorbos.com/explorar; the Art. 4.012A button appears when the municipality enabled this path.
• Use the contact-the-municipality button on the property page: estorbos.com documents your expression of interest with a timestamp, and that gives the priority practical force, because the window is measured in dates.
• Contact the municipality directly, identify the property by cadastre number and address, and if you believe you qualify for the priority, say so and be ready to support it with documentation under the local ordinance.

Estorbos.com handles no funds and represents no one before the municipality; it keeps the public record of who expressed interest and when.

The transfer and what comes after

The sale does not follow Path A's rule: the municipality, through an ordinance approved by the Municipal Legislature and signed by the mayor,¹⁵ can adopt the requirements and rules to transfer or sell what it acquired by purchase or through the summary track, for built properties rehabilitable as residences. Each municipality can set different requirements: ask for the ordinance in force before making plans.

Once title is received, the same closing rule as on every path applies: Article 4.014 gives one year from the transfer to rehabilitate, rebuild, restore, or demolish, or the municipality may exercise the conventional repurchase action under the Civil Code.¹⁶

One alternative the law enables: those that created a Community Land Bank by ordinance (Art. 4.005) can channel abandoned, vacant, or ruined properties into that nonprofit entity to rehabilitate them and return them to productive use, including affordable housing.¹⁷ That world is covered in the affordable housing, auctions, and CLB guide.

What the municipal transfer ordinance usually sets

Because the law delegates the details, the local ordinance is the document you should read first on this path. The best verified example is San Juan, which built the 4.012A regime into its Urbanism Code: its text requires considering the first option for those with limited access to the traditional market¹⁸ and grants the local funding window,¹⁹ with the same pieces as the state article. Other municipalities, like Aibonito in its 2026 amendment, replicate the full scheme inside their nuisance programs²⁰. When you request your municipality's ordinance, look for three things: the criteria to prove limited access, the procedure to exercise the first option, and the payment and closing conditions of the sale.

A sample calendar

Suppose the municipality declared the property on March 1, 2026 (an illustrative date). The priority window runs until March 1, 2027: during that year, if you qualify, you are not a third-party acquirer. If you expressed interest and qualify, your year to secure funds could stretch, with the six-month extension, to mid-2028. If no one showed interest in the first year, or your term lapsed without a purchase, the municipality is free to sell to anyone, investors included. The takeaway: document your interest as early as possible, because the window does not stop.

If you are the owner and a summary complaint arrived

The same deadlines that make this path fast for the municipality are the ones running against you: 20 days to answer (30 by edicts), no extensions, with default and judgment in 5 days if you do not respond. Get legal advice immediately, check that the nuisance declaration was made with proper notice, and remember the compensation set in the judgment must be claimed within 3 years. Your rights in the earlier administrative phase are explained in the guide for notified owners.

Where this path fits

If you have funds and want to initiate the acquisition of a specific property yourself, your route is Path A, the letter of intent. If your municipality expropriates first and sells at auction, see Path C, the auction model. And to see them side by side, the three-path comparison.
