Mexico
Answer ... Mexican law is extremely formalistic as regards the service of summons. It is therefore imperative to engage local counsel when serving summons on the defendant in the foreign proceeding.
Public policy is another tricky issue that must be addressed. When foreign cases take place, and it’s foreseen that recognition and enforcement of the award will likely be in Mexico, local counsel should be engaged to review and analyse the merits of the case and its role with regard to Mexican public policy.
