AC Milan and Inter’s plans to build a new shared stadium have been hit by another potential delay after a Milan resident took the city authorities to court over the transfer of land surrounding San Siro.
The legal challenge concerns the sale of the site to Stadio San Siro SpA, the joint company connected with the two clubs. The transaction was formally completed on 5 November 2025, but the claimant argues that Milan’s municipal authorities deliberately accelerated the process so it could be concluded just five days before the stadium’s 70th anniversary.
Under the circumstances described in the court action, San Siro would have automatically received protected status after that anniversary. Such protection would prevent the stadium from being sold or demolished, making the timing of the land transfer central to the dispute.
The case raises a fresh obstacle to the clubs’ long-running plans for a new ground. AC Milan and Inter had been hoping that completing the land deal would allow work on a shared stadium to move forward more quickly. Instead, the new court proceedings could lead to a prolonged legal process and postpone the start of construction once again.
The lawsuit challenges the legality of the municipality’s decision to transfer the land around San Siro to Stadio San Siro SpA. The transaction has already been completed, but the resident’s claim places renewed focus on whether the authorities were entitled to conclude it before the anniversary date.
According to Football Italia, the claimant believes the five-day gap was significant because it allowed the transfer to take place before the protection rules were triggered. Once that status applied, San Siro would no longer be available for sale or demolition, potentially affecting the clubs’ plans for the area.
The future of San Siro has been at the centre of discussions involving AC Milan and Inter as they seek a modern shared home. Their intention to move ahead with a new stadium has depended on resolving questions surrounding the existing ground and the surrounding land.
The latest legal action means the project faces uncertainty at a time when the clubs had expected progress. Rather than clearing the way for construction, the completed transfer has become the subject of a dispute before the courts.
The effect of the case will depend on how the challenge develops, but it could delay the beginning of building work and extend the uncertainty over the clubs’ stadium plans.
