KLC Law Firm was established in 2000 in Athens through the merger of three law firms.

Highlights

KLC acted as lender's legal advisor to National Bank of Greece (acting for itself and for and on behalf the Hellenic Republic) in respect to the first project financing of a 50 MW battery storage project developed by a local subsidiary of Elsewedy Electric. KLC conducted the due diligence, negotiated and drafted the finance documents, and assisted the lenders in the financial close, which took place in January 2025. The EUR34 million deal also involved English, Egyptian and Cypriot law.

The firm acted as legal advisor to the 100% shareholder of insurer Europe Asfalistiki, in a transaction which combined the sale of its entire share capital to Intracom Group and the acquisition of a 10-15% stake in Europe Asfalistiki’s new Athens Stock Exchange-listed parent company.

The transaction entailed a multi-step restructuring, involving stakeholders such as the Bank of Greece and the Hellenic Capital Markets Commission. The MoU was signed in January, binding SPA signed in October 2024 and closing is expected within 2025.

A team also advised Hellenic Republic Asset Development Fund (HRADF) on the Corfu Mega-yacht Marina sub-concession and Philippos B port sub-concession. The former, signed in October 2024, involved the construction, operation, management, maintenance, and exploitation of the Corfu Tourist Port by a subsidiary SPV of Lamda Development. The latter concession, signed in January 2025, pertained to the sub-concession of Philippos B port, part of the greater Kavala port, by a subsidiary SPV of Terna. KLC handled complex public procurement and administrative law issues, including pre-contractual audits by the Court of Auditors.

Anastasia Karousou joined as a senior associate in the energy department from Lambadarios Law Firm in January 2025.
