Mergers and acquisitions
M&A lawyer in Luxembourg
The firm supports the acquisition or disposal of your SME in Luxembourg: valuation, due diligence, negotiation of the heads of terms, drafting of the SPA and of the asset and liability warranties.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
A successful M&A deal is decided as much in the preparation as at signing: rigorous due diligence, negotiation of warranties and a robust sale agreement protect your price and limit your exposure after the deal.
Cerno Law Firm runs the entire M&A process for SMEs and their directors, from the first audit through to closing and post-acquisition management.
The need
You are buying or selling a company, shares or a business, and need to secure the price, the warranties and the terms of the deal.
Without due diligence or a robust SPA, the buyer discovers the liabilities too late and the seller remains exposed after the sale.
The risk
Hidden liabilities, a poorly secured price, ineffective asset and liability warranties, badly drafted conditions precedent, post-acquisition litigation.
A poorly documented deal turns a disposal into a lasting source of dispute between seller and buyer.

FAQ
Frequently asked questions
Why carry out due diligence before buying?
To identify liabilities, contractual and tax risks, and adjust the price or warranties accordingly. It is the buyer's best protection.
What are asset and liability warranties?
It is the seller's undertaking to indemnify the buyer if a liability predating the sale comes to light afterwards. Its drafting is decisive.
Does the firm also support the seller?
Yes, the firm acts for buyers and sellers alike, securing the price, the warranties and the timetable of the deal.
Does Cerno replace an investment bank?
No. Cerno is a law firm admitted to the Luxembourg Bar that secures the legal side of the deal; the lawyer remains at the heart of the negotiation and drafting.

What our clients say
Had a consultation with Me Cora Maglo about my Luxembourg Blue Card application. She explained everything clearly: the process, timeline and documents I need, and helped me with my wife’s family reunification too. Honest and practical advice. I felt confident after talking to her.Farshid Pourlatifi
J’ai beaucoup apprécié le service de Maître Maglo : son sérieux, sa sympathie, son professionnalisme et sa disponibilité. Toujours répondu rapidement et clairement, avec des conseils pragmatiques, sans pousser à des procédures longues et coûteuses lorsqu’elles ne sont pas justifiées.Nathan Wirtzfeld
