Quick answer: Checking a Spanish developer takes 2 to 3 days and under €25 in documents: a Registro Mercantil note (~€5 to €10) proves the company exists and files accounts, a free BORME scan surfaces insolvency events, a €9.02 nota simple proves the promoter owns the plot, the town hall confirms the building licence, the draft contract names the Ley 57/1968 guarantee issuer, and delivered phases test the track record. A scheme that passes all six deserves a reservation; a scheme that fails any one has told you where the risk lives.
Why verify the developer when the scheme looks established?
Marketing polish is the one thing every off-plan failure in Spanish history had in abundance, which is why verification runs on documents rather than showrooms: the checks below cost under €25 and 2 to 3 days, against stage payments that routinely reach 30% to 40% of the price before delivery.
| What the showroom proves | What it does not prove |
|---|---|
| A marketing budget exists | The promoting company owns the plot |
| The scheme is designed | A building licence has been granted |
| Sales are being made | Stage money will sit behind a guarantee |
| The brand is visible | The SL you contract with has filed accounts |
History gives the argument its teeth. Spain’s 2008-to-2013 off-plan collapse stranded buyers whose promoters had sold from renders without licences, built on unowned land, or banked deposits without the Ley 57/1968 cover, and the modern rules that protect today’s buyers are a direct response to that period. The rules work when invoked; the six checks below are how a buyer invokes them.
Scale changes nothing about the method. A buyer at a 4-unit boutique scheme and a buyer at a 200-unit phase from a listed group run the same list; the listed group simply passes several steps by publication. On this site’s own coverage, the reviews of Aedas Homes, Neinor Homes and the Metrovacesa hub apply exactly this framework, which is what separates a review from a brochure.
Insider tip: run the checks before the reservation, not during the purchase contract review. The reservation window is 2 to 6 weeks and your fee is already committed inside it; the same checks run 3 days earlier cost the same €25 and protect the fee too.
What does the Registro Mercantil tell you, and what does it cost?
A Registro Mercantil information note costs roughly €5 to €10 through the registrars’ online portal, arrives the same day, and answers the first four questions of the whole exercise in one document: the promoting company exists, when it was incorporated, who currently directs it, and whether it has filed its annual accounts.
- Identity. Exact company name and CIF against the reservation form and draft contract. The company on the brochure and the company you pay are frequently different entities; both need reading.
- Age. Incorporation date against the project timeline. A company formed 20 years ago with 15 filed accounts reads differently from one formed 4 months before the launch.
- Directors. Names to search, groups to connect. Directors shared with an established group corroborate the marketing; directors traceable to dissolved promoters deserve the next hour of your research.
- Accounts. Filed or not, and the depósito year. Non-filing is legal for a young SPV and still shifts the burden of proof onto the guarantee and licence checks.
BORME, the companies gazette, is the free companion: insolvency declarations, administrator changes and capital events publish there, and a name search costs nothing at the official portal. A promoter mid-concurso (insolvency process) is findable in minutes, which is precisely why the check belongs in the sequence even when it almost always comes back clean.
Reading matters more than collecting. The note is 2 to 4 pages; the reading is the comparison against the papers in your hand: same CIF on the reservation, the draft contract and the account you are asked to pay, directors consistent with the group story, age consistent with the claimed track record. Mismatches are questions to ask in writing, and the due diligence guide sequences where those questions sit.
Red flag: a sales office that cannot or will not name the promoting company precisely, “it is part of the group” without a CIF. The entity that signs the contract is the entity that owes you the building; a group that will not name it before the reservation has inverted the order of trust.
How do you confirm the promoter owns the land?
Land ownership is a €9.02 question with a same-day answer: the plot’s nota simple from registradores.org shows the registered owner and every charge on the land, and the promoter selling you a future flat should be the titular of the finca it stands on, typically confirmed inside 2 working hours of ordering.
- The titular test. The registered owner matches the promoting company on your contract, or the note shows a registered purchase option or urbanistic arrangement explaining the difference in writing.
- The charges read. Development finance appears as a mortgage on the plot; normal, and worth sizing. An embargo or a charge cascade from unrelated debts is a different pattern.
- The division check. On a scheme mid-build, the horizontal division (división horizontal) shows whether your future unit legally exists yet as a finca; before it does, your contract rights and the guarantee are what you own.
Charges deserve one honest paragraph, because a mortgaged plot alarms buyers unnecessarily. Developers build with bank finance secured on the land, the charge is discharged or distributed as units complete, and its presence usually means a bank has already underwritten the scheme, which is weak but real third-party validation. The question is proportion and holder: a construction loan from a named bank reads as normal; multiple charges from non-bank lenders stacked in 6 months reads as a promoter running out of road.
Buyer scenario: a French buyer checking a 14-unit Alicante scheme in 2026 found the plot registered to a company that was not the promoter on her reservation form. The explanation was ordinary, a group land-holding SL, but it surfaced only when asked, and the corrected contract named both entities and the transfer mechanism. The €9.02 question upgraded her paperwork; the buyers who reserved the same week on the original form hold contracts with a seller that does not own the land and an explanation they have never read.
How do you confirm the building licence exists?
A building licence (licencia de obras) is the town hall’s permission for the specific plot and project, and confirming it costs €0: one written question to the urbanismo department plus one written answer from the developer with the licence reference, an exchange of 3 to 10 days that screens out the worst failure mode in Spanish off-plan history.
| Question | Good answer | Answer that ends the purchase |
|---|---|---|
| Does a licence exist for this plot? | Reference number, grant date | ”In process”, “imminent”, “pre-licence sales” |
| Does it match the marketed scheme? | Units and heights consistent | Licence for 12 units, marketing for 20 |
| Any suspension or challenge? | None on record | Judicial suspension, planning appeal |
Selling before the licence was the signature of the pre-2008 disasters, and modern practice at serious developers is the opposite: launches follow licences, and the reference number is volunteered in the legal pack. The Ley 57/1968 guarantee machinery also interlocks here, since guarantee lines are arranged against licensed schemes; a promoter taking money without a licence is usually also a promoter without certificates, and the bank guarantee guide explains why that combination is the one that costs buyers everything.
Timing nuance for honest cases: large phased developments hold licences per phase, and a launch of phase 3 while phase 2 builds is normal, with the licence question asked per phase. Equally, a declaración responsable regime covers some works in some regions, but a residential new build sold off-plan runs on a granted licence, and no regional shortcut changes that answer.
Checklist for this step: written question to urbanismo naming the plot’s cadastral reference, written answer from the developer with the licence number and date, and the two compared side by side. The drafting takes under 1 day of anyone’s attention, the answers arrive within 3 to 10 days, and the historical failure mode with the highest body count is off your list for €0.
What does the Ley 57/1968 guarantee line prove?
A named guarantee line is the strongest single external check on the list, because it proves a regulated bank or insurer has underwritten the promoter’s duty to return stage money that typically reaches 30% to 40% of the price before delivery. The draft contract names the issuer; every later payment generates a certificate against that line.
- What to demand at the checking stage. The issuer named in the draft contract (bank or authorised insurer), the mechanism stated (aval bancario or insurance policy), and the promise that each payment produces an individual certificate naming your unit and amount.
- What the issuer’s involvement tells you. A regulated entity has reviewed the promoter, the scheme and the licence before lending its balance sheet. Their credit committee did part of your due diligence, with better access.
- What its absence tells you. A contract silent on the issuer, or promising “guarantees will be arranged”, is a scheme where the strongest protection in Spanish off-plan law is not yet real.
Mechanics live on the dedicated page, and the split of labour is deliberate: this page verifies the line exists before you commit; the bank guarantee guide owns certificate-by-certificate verification through construction, and the payment schedule guide owns the calendar those certificates follow. At the checking stage one sentence in the draft contract, with one issuer name you can verify is a regulated entity, carries the weight.
Underwriting snapshot from our files: across the 120 schemes reviewed on this site, the guarantee line was named in the draft contract at every scheme from the listed developers and at most established regional promoters, and the exceptions clustered exactly where the other checks also struggled, young SPVs with thin registry files and licences described as in process. Protections correlate in both directions: a scheme that passes the licence check almost always passes the guarantee check, a scheme that fails one has usually failed both, and that correlation is why running all 6 checks costs barely more than running 3, under €25 and inside 3 days either way. The pattern is the closest thing off-plan buying has to a law of nature: paperwork quality is one variable, visible early, and a contract silent on the issuer is the red flag that predicts the rest. The reservation desk is where it shows first.

Get a developer checked before you reserveHow do you read a developer’s track record?
Track record is delivered buildings measured against dated promises, and it is checkable at three depths: published audited figures for the listed groups, visited completed phases for regional promoters, and directors’ histories for first-time SPVs, with the effort rising from 1 hour of reading to 2 days of calls as the paper trail thins.
- Listed developers. Aedas Homes (AEDAS), Neinor Homes (HOME) and Metrovacesa (MVC) publish audited delivery counts, land banks and completion calendars; a buyer reads them in the annual report rather than taking the salesperson’s word.
- Established regional promoters. Ask for the last 3 delivered schemes with addresses and delivery dates, then test one: visit, talk to the community administrator, compare the promised delivery quarter with the acta de recepción date.
- First-time SPVs. The company has no history, so the people are the record: directors’ previous schemes, the architect’s and builder’s portfolios, and the guarantee issuer’s willingness to lend its name.
Delay history reads differently from failure history, and conflating them misprices real schemes. Spanish deliveries run late by 3 to 6 months routinely, and a promoter whose last three phases each slipped a quarter but delivered to spec, with penalties honoured, is a normal counterparty whose delays you price into your own planning. A promoter with a delivered building whose community is litigating structural defects under the Ley 38/1999 warranty is a different animal wearing the same delay statistics.
Case study in reading depth: two Costa del Sol schemes we compared in 2026 both claimed 15 years of experience, in identical brochure language, at similar price points near €400,000. Group A’s claim traced to 11 delivered developments verifiable through the registry, with two community administrators who took the call and confirmed delivery quarters, snagging behaviour and warranty responsiveness. Group B’s claim traced to one director’s previous employment at a large promoter that had delivered the schemes in question; his own company, the actual counterparty on the contract, had delivered nothing under its own name. Neither claim was false as worded, which is the point: marketing language is lawyered precisely to survive this kind of reading. Only one of the two was a track record in any sense a buyer can rely on, and surfacing the difference took roughly 2 hours of checking against documents that together cost under €20.
Is a per-project SPV a red flag?
A single-project company is standard Spanish development practice rather than an automatic red flag: promoters have ring-fenced each scheme in its own SL for financing and liability reasons for over 20 years, roughly one new company per development, and the meaningful question is never why the company is new but who stands behind it and whether the guarantee line is real.
| SPV pattern | Reading |
|---|---|
| New SL, established group named in contract, guarantee line from a major bank | Normal structure, verify the group link in writing |
| New SL, group in marketing only, guarantee line named | Acceptable; the guarantee carries the weight |
| New SL, no identifiable group, guarantee “being arranged” | The risk is unpriced; step back |
| New SL, directors traceable to failed promoters, no licence answer | The pattern the checks exist to catch |
Group linkage belongs in the contract, not the brochure. A parent company named in marketing has promised you nothing; a contract clause naming the group entity as guarantor, or a guarantee certificate from a regulated issuer, is enforceable paper. Asking for one or the other is a standard request that established groups meet without friction, usually because the financing bank already required the same clarity.
Perspective closes the loop: the SPV question is where all six checks converge, because every check is a way of seeing through the corporate shell to something real. The registry shows the shell’s contents, BORME its health, the nota simple its land, the town hall its permission, the guarantee line its banking, and the track record its people. Six views of one question, under €25, inside 3 days, and the full off-plan guide places them in the purchase timeline end to end.
Closing verification checklist
Eight lines, run before the reservation fee moves.

Frequently Asked Questions
Six checks in 2 to 3 days for under €25: Registro Mercantil note, free BORME scan, plot nota simple, building licence at the town hall, the Ley 57/1968 guarantee issuer named in the contract, and the delivered track record tested.
Existence, incorporation date, directors, capital and filed accounts, for roughly €5 to €10 online. A young SPV with no accounts is not fraud, but it moves the burden onto the guarantee and licence checks.
No, SPVs are standard ring-fencing practice. The real questions are who stands behind the SPV in enforceable paper and whether a regulated issuer has put its name on the Ley 57/1968 guarantee line.
One written question to the town hall's urbanismo naming the plot, one written answer from the developer with the licence reference, and the two compared. 'Licence in process' is treated as no licence.
Aedas Homes (AEDAS), Neinor Homes (HOME) and Metrovacesa (MVC) trade on the Spanish exchange with audited delivery figures, which makes their track records verifiable in the annual report rather than the sales office.
Under €25: the registry note at €5 to €10, the nota simple at €9.02 plus VAT, BORME free, and the licence exchange costing only an email. Skipping the checks is the expensive option in every file we have reviewed.
