The item is an Arbitration rulebook containing legal terminology. The English edition has been recently updated from the 2011 version and the same updates must be applied to the Arabic version. The two documents provided are:
1. The English 2016 edition with track changes enabled to show the difference between 2011/2016 in red and blue.
2. The Arabic 2011 edition.
I am fluent in Arabic myself but unfortunately I do not have an Arabic keyboard so this would take me too long. There is roughly 10 pages of text to translate, some deleting required, and just general formatting to make it look like the English 2016 edition. Message me and I can show you what needs to be done.
