Legal exclusion is generally equated with unequal access to legal protection institutions and facilities; it is also understood as “a qualified type of discrimination created by law”. It turns out that in the sphere of legal systems, exclusion is largely caused by the law itself. There is a problem of certain social groups (e.g., people with disabilities) not benefiting from the rights granted to them, which is related, among other things, to the low level of legal awareness, the lack of understanding of the law, poor information on the applicable laws, or the high cost of legal counsel. Individuals, especially those with disabilities, do not always (despite assumptions to the contrary) realize that by participating in society, they become links in a chain of social relations regulated by law. One of the main obstacles to combating social problems is inadequate information on existing legislation and poor understanding of institutional and legal intricacies, which make excludable individuals know little about their rights and protections. Serious consideration should be given to simplifying certain solutions (e.g., applying the concept of legal design), which can become a method of preventing social and legal exclusion.
