It is useful for our institution to receive the regulatory alert bulletins. It has been very useful for our institution to attend their executive forum – current state of the economy. We have always received timely, friendly and efficient attention. We have had contact with Iver von Borries.

Wayar & von Borries is, in our opinion, the best law firm in Bolivia. The solvency in the knowledge of its partners and the mastery in oil and gas law and above all the quick response. Something that we love about this firm is that its partners are available at all times, via video calls. They have also just released an application (APP) where laws, articles with legal analysis, among others, are available. It is a great firm that is characterised by the seal of excellence that it puts on everything it does. Iver von Borries and Javier Romero are the ones who assist us in all our matters. They are accessible lawyers, always available, either by video call or in person when needed for meetings with our clients or authorities. Iver von Borries is undoubtedly the most knowledgeable lawyers in oil and gas law in Bolivia. He continually appears as a guest at prestigious events and is an opinion leader on these issues in Bolivia. Javier Romero has very solid knowledge in contracting with the state, which makes him essential when signing contracts with public companies in Bolivia, especially in oil and gas matters.

What stands out is the team’s availability through video calls for meetings, the facilitation of virtual audiences, the ease of having the equipment anywhere in the world, regardless of country time, and the offering of multiple resources to take care of all the details, according to the client’s need. Wayar & Von Borries is an outstanding team of professionals that complements the knowledge of each of its partners and associates to provide multidisciplinary advice.
