The translation of a university degree may be necessary if you are applying for a scholarship, are finishing your studies abroad, or you want to find a job abroad (or in the UK in the case of foreign university degrees). The translation is the only way for you to prove that you really have that degree.
In addition, for it to be valid, it is important that it is a sworn translation. In other words, it should be conducted by a sworn translator, accredited by an official authority or notary.
