The concealment, disguise or avoid knowing the origin or nature of money is considered a crime whose name is money laundering or money laundering. This subject of study that is increasing every time, has caused justice to intensify its regulations to combat it. In the same way has turned those who favor this activity into real cover money. Many attribute the beginnings of money laundering to Colombia, a country identified with drug trafficking, which turns out to be the main cause for this crime that significantly harms the economy of each country, being considered as a global problem. This country has taken many measures to prevent money laundering, as well as intensifying and strengthening penalties for those discovered in the crime of money laundering. These have favored its decline. In Ecuador, a neighboring country that is currently experiencing the same social and criminal problems, no preventive measures have been applied that reduce money laundering by a large percentage, facts that favor drug trafficking and other crimes so that money laundering not only increase, but intensify. In the present work we will study the current laws of the Colombian country as the Ecuadorian in an analytical and comparative way to know the aspects in which each legislation could improve.
