“Guided by ethics and the will to resolve, not to feed the conflict.”
“Lawyers who have been on both sides of the table.”
Lawyers admitted in Spain (Madrid). Attorneys at Law admitted in the US (New York). Graduates in Psychology. Over 25 years of experience advising, leading in-house legal departments, and resolving corporate and wealth disputes.
We act as your legal director and counsel, as close as if we were part of your team.
Some of the situations in which we can help you find a solution.
The company is deadlocked and litigation would destroy the value you have built. Mediation can unblock the situation in weeks, with total confidentiality.
02Dividing an estate or handing over the family business creates tensions that threaten family unity. We help preserve both wealth and relationships.
03Your business already generates enough legal work to need constant senior judgement, but not enough to justify a full in-house legal department. We act as your External General Counsel: the same availability, without the fixed cost.
04A due diligence, a valuation gap or a warranties clause is holding up closing. We bring M&A and mediation experience to find the way out.
05You have spent years in court proceedings that drain resources with no solution in sight. Mediation resolves in months what a court will take years to decide.
06You are about to acquire, sell or restructure a company and you need the deal negotiated and closed with the guarantees (representations, price adjustments, earn-outs) properly secured.
07You are coming from abroad to invest or establish yourself in Spain and you need a counsel who understands both your home legal system (including the US) and the Spanish one.
08You want to plan succession, give structure to the family business or protect your assets before conflict arises, with a tailored protocol or plan.
09You need to review or negotiate a shareholder agreement, structure the company governance, carry out a capital increase or update regulatory compliance, before a problem becomes a conflict.
10Or simply the wish to decide now who should assist you the day you need it, and who should not. Since 2021 you can set it out yourself, and the law prefers it that way.
11Minutes and corporate books unfiled, accounts due, and headquarters asking for everything in English. Someone has to own the corporate calendar.
