In my thesis first of all I describe historical progress of trade business in the Czech Republic from it's beginning: the developement of guilds, manufactures, damping during the Second World War and developement after 1989 up to actual legal regulation. I will describe trade administration and its developemnet from 1992, when Trade Licensing Offices started up, and the position of Trade Licensing Offices in the public administration. I will describe the basic terms like trade, trade licence, its beginning, expiration and authentication, trading inspection and administrative penalization. I will describe Trades Register, its connection to other registers of public administratin and the activity of Central registration points. Currently a big amendment to the trade law legislation is being prepared. This amendment is about to reduce administrative burden of entrepreneures greatly and allows the enterpreneurs to start their businesses easily. In my thesis I try to describe the most essential changes which this amendment to the trade law brings.
