It is known as legal relationship to the link, established and regulated in a legal manner, between two or more subjects with respect to certain interests. It is a relationship which, due to its legal regulation, generates legal effects.
In other words: a legal relationship is one that legal subjects forge when a normative assigns certain consequences to the link. From them come Rights Y obligations that bind the intervening parties.
That is, the basis of the legal relationship is that it determines that one party has the power to demand something that the other must comply with.
A legal relationship, therefore, has subjects (the legal or natural persons that are linked), contents (the rights and obligations shared between these people) and a object (a fragment of social reality that is determined by the relationship in question). Regarding the subjects, there are people to which rights are assigned and others who assume obligations regarding the fulfillment of said rights.
As a general rule, you have to know that legal relationships are also known as subjective rights and these we can establish that they are divided into two large groups:
-Civil rights, which are those that belong to the owner of the same based on who is an inhabitant. In this group are, in turn, personality rights, family rights (parental authority, conjugal rights …) and property rights. The latter are divided into three large groups: personal rights, real rights and intellectual rights.
-Political rights, which are those that the person in question has for being part of a political community and for being a citizen.
Based on the above, there are various kinds of legal relationships. The family relationships are those that arise as warranty of the family institution. The law establishes, for example, that parents have the obligation to guarantee the support of their children until they are of legal age.
The succession or hereditary relationships, on the other hand, they contemplate the rights and obligations that individuals who are successors of someone deceased have (such as the right to inherit their goods).
The legal-real relations (linked to the right of a subject to act as appropriate with respect to the assets of his property) and mandatory relationships (the obligation to respect the rights of another person) are other types of legal relationships.
In addition to all the above, we cannot ignore other data of interest related to the legal relationship, among which the following stand out:
-There are three theories about it. One, the so-called theory of the two subjects, which says that it always occurs between two subjects; the eclectic, which says that it can occur both between people and between people and things; the theory of law on the object, which considers that the legal relationship is that which links a person with an object.
-In any relationship of this type there are various elements that come into play: subjective, personal, objective, causal, formal and even coercive.
