We provide authority in our knowledge in family law in Argentina to be examined by a court for the benefit of it. We give evidence of our opinion as expert witness in court, especially in the United States on the topic of family law in Argentina, and everything else relative to our knowledge. We also prepare affidavit, reports to be presented in foreign courts. We have extensive expertise on presentations in different foreign countries; we know how to do it. Please read very carefully if you are going to authorize your son to come to Argentina, it is high a risk country. It is possible he/she never return home. If you have any doubt, avoid it and an expert witness is a good way a judge understands how bad it could be for your child and for you a travel to Argentina.
