25 Million in Focus: Trial of Matthias Kühn in Palma and What the Island Should Learn

A trial in Palma centers on allegedly undisclosed liabilities of around €25 million. What does this mean for Mallorca's real estate sector, local residents and the rules needed to ensure transparency?

A court date that concerns more than numbers

On the morning of 20 October 2025, Via Alemania was unusually quiet. A few tourists pulled their jackets tighter, the coffee aromas from Passeig Mallorca mixed with the smell of chlorine from a nearby construction site — and a handful of photographers and onlookers gathered in front of the courthouse. At the center: the German investor Matthias Kühn. The accusation is that liabilities to the Spanish tax authority of around €25 million were not properly disclosed.

The key question: accounting clumsiness or deliberate circumvention?

Investigations have been ongoing for more than two years, and earlier reporting detailed related searches and arrests in Palma in Major Raid in Palma: What the Investigations Mean for the Island. The public prosecutor's office and tax authorities are examining fund transfers within a corporate network — Spain, Liechtenstein and apparently other destinations play a role. The central question the court must answer is not only: Were numbers reported incorrectly? But: Was the system structured in a way that deliberately avoided tax obligations?

There is another detail: the court ordered a security bond of around €33 million. Appeals have been filed against this order. Such sums are not only legally explosive; they also cast a harsh light on the entanglements in Mallorca's real estate world, as documented in Palma on Trial: The Major Real Estate Fraud and the Question of Justice.

Who else comes into focus

The hearings are scheduled over two days. Kühn is to testify first, followed by several named witnesses — including family members, advisers and lawyers, such as Jorge Sainz de Baranda, similar to episodes described in Major Raid in Palma: What the Searches of Law Firms Mean for the Island. So this is not a single-person case, but a web of statements, contracts and bank movements that must be examined.

Interesting and often underemphasized in public debate is the role of service providers: tax advisers, trustees and banks. They are not merely background figures. Their documentation, checks and advice often decide whether a structure is legally clean or slips into a grey area. If it turns out that external advice created loopholes, questions would also be raised about the industry.

What this could mean for Mallorca

For the island, such proceedings are more than gossip. Mallorca depends on construction projects, investments and foreign capital. When a prominent investor becomes the subject of tax investigations, there are several effects: mistrust of project financing grows; authorities and administrations become more cautious with approvals; and local companies could be tainted by association even if they operate lawfully.

This becomes clear in conversations on site. A woman walking her dog on the Passeig dryly said, "You hear a lot, but you know nothing." That is the problem: rumours mix with legally verifiable facts. As long as the judiciary does not provide clarity, a shadow remains over projects and investments.

The blind spots of oversight

In many cases it is not only the main actors, but cross-border structures that make oversight difficult: complicated holding arrangements, accounts in multiple jurisdictions, and advice from firms in tax havens. What is often neglected here is the question of responsibility — who audits the auditors? And how can local authorities ensure transparent ownership structures before large construction projects are given the green light?

Another point: evidentiary documents are often located in different legal systems. Cooperation between Spanish authorities and institutions in Liechtenstein or other countries is time-consuming and politically sensitive. That delays clarification and weakens public trust.

Concrete steps that would make sense now

The court can clarify the case legally. For the island society, measures go beyond that. Some practical proposals:

- More transparency in property purchases: Mandatory disclosure of the true beneficial owners before approvals. No big deal without a clear ownership structure.

- Stronger checks by awarding authorities: For public contracts, independent audits and financial guarantees should be mandatory.

- Better international cooperation: Simplified channels of information between tax authorities could speed up investigations.

- Raising awareness among local actors: Construction companies, banks and brokers must strengthen their compliance — not only for legal reasons, but to regain the trust of the neighbourhood.

Outlook

The upcoming hearings will show whether these are serious violations or complex but legally permissible constructions. Regardless of the outcome, the lesson is clear: Mallorca needs more transparency in the real estate world. After all, it's not just about millions in bank accounts, but about the integrity of entire projects, jobs and how we do business together on the island.

I will follow the trial and report further as soon as new details emerge from the courtroom.

Frequently asked questions

What is the Matthias Kühn trial in Palma about?

The trial in Palma concerns allegations that liabilities of around €25 million to the Spanish tax authority were not properly disclosed. Prosecutors are examining whether this was an accounting error or part of a deliberate structure to avoid tax obligations. The case also involves fund transfers across several jurisdictions and has drawn attention because of its scale.

Why is the Matthias Kühn case important for Mallorca?

The case matters for Mallorca because it touches the island’s real estate and investment world, where trust is essential. A high-profile tax investigation can make authorities more cautious, unsettle project financing, and create reputational pressure on local firms even if they are not directly involved. It also raises broader questions about transparency in property deals on the island.

What does the €33 million security bond in Palma mean?

A security bond is money the court can require to protect possible financial claims during legal proceedings. In this case, the bond ordered by the court is around €33 million, and appeals have already been filed. Such a large amount underlines how serious and financially complex the proceedings are.

How do cross-border company structures complicate tax investigations in Mallorca?

Cross-border structures can make it harder to trace who controls money, contracts and ownership. When accounts and companies are spread across several countries, investigators often need cooperation from different authorities, which takes time. That is one reason cases linked to Mallorca can remain unresolved for a long period.

What can Mallorca learn from the Matthias Kühn case?

One clear lesson is that large property and investment projects need more transparency. Local authorities, banks and advisers may need stronger checks on ownership structures, financial guarantees and compliance. The case also shows how quickly confidence can weaken when the public cannot clearly see who is behind a project.

What does a Palma court hearing usually involve in a case like this?

A hearing of this kind typically includes testimony from the main defendant and later from witnesses such as family members, advisers and lawyers. The court looks at documents, contracts and bank movements to understand how the structures were built and whether they were lawful. In a complex case, the hearing is often only one step in a much longer process.

How can Mallorca property buyers check who really owns a company?

Buyers should ask for clear ownership information before signing anything and make sure the beneficial owner is disclosed. In Mallorca, that is especially important when a deal involves companies, trusts or international structures. Independent legal and financial advice can help reduce the risk of hidden liabilities or unclear control.

Why are lawyers, tax advisers and banks relevant in the Mallorca case?

They are relevant because they often shape how company structures are set up and whether the checks around them are strong enough. If advisers create loopholes or fail to flag risks, that can become part of the wider legal and ethical discussion. The case therefore goes beyond one investor and also raises questions about professional responsibility.
