Copyright exists automatically, without any registration in:
Usually the creator of the work. This is the case if you commission a work - the creator will own the copyright unless you agree in advance that it will belong to or be assigned to you. Copyright in work created by an employee during the course of employment belongs to the employer. Problems can arise when the work is created jointly by 2 or more people. It is always better to consider copyright ownership in advance and deal with it in writing.
Protection is automatic in the UK. There is no system of registration and it is not necessary to mark your work with the recognised (c) symbol followed by the owner's name and the date or year of publication but it is advisable to do so, even if only to mark the year of publication and demonstrate your awareness of your intellectual property rights which may deter infringers.
