Concubinage in Peru our code Civil in its article 326 regulates concubinage considering it as: the union indeed voluntarily made and maintained by a man and a woman, free matrimonial impediment, to achieve goals and carry out duties similar to the marriage, provided that such union has lasted at least two continuous years. This should be understood as concubinage perfect, since concubinage in the strict sense is a typical of a man and a woman standing with the note of faithfulness and honesty and continuous and unimpeded to transform in marriage, however must be understood in its broadest sense concubinage as the union will indeed that occurs between free people or people with marriage with third parties therefore have impediment to legalize this union. The determining causes of concubinage include social, legal, economic and cultural causes social causes: because of social inequality that exists in our country, is one form of contribution to the constitutions of fact, as for example in the Andean zones for social reasons they opt for the servinakuy or marriage to test. Economic reasons: Due to insufficient economic underdeveloped countries as the Peru, where there are low income or poverty give rise to proliferation of joints in fact, although some have the purpose of celebrate the civil marriage, due to their limited income are not able to assume the costs of a marriage, although given the mass marriage in the municipalities but due to expenses which must assume to travel to local the municipality induces them to persons follow the path of concubinage. Legal causes; The legislator has opted for two legal institutions such as: marriage and divorce, however the formalities for the celebration of the marriage, are not the most appropriate since hinder it rather than facilitate it and not promote it, because these formalities concubinage is promoted. Cultural causes; In fact unions are given in our country with greater intensity in places where the population is low level cultural and economically poor reason not aware of replacing joints in fact by marriage, or who choose to follow their ancestral customs, or religious marriage which is not more than another way of promoting concubinage. The both social, economic, legal and cultural causes contribute to concubinage however the legislator should opt to give a solution to this and not ignore it but regulate it or welcome him within a coercible standard for its demise or removal, or protected giving guarantees, can opt for two roads such as; seek its depletion or eventual demise or lend amparo or confer validity you need, since children are being harmed from the instability of the union, and the cohabitant to dissolve the union remains stripped many times by his domestic partner of heritage which both have formed since it generates one of them unjust enrichment.
