These documents are draft transcriptions of the documents relating to the Templars' property in Nottinghamshire which are preserved at Kew: The National Archives of the UK. There is an inventory of the Templars' property at TNA E142/12, a statement of debts due to the Templars, and a petition dating from the 1330s.
The documents in the National Archives are covered by an Open Government Licence for public sector information, which allows everyone to copy, publish, distribute and transmit the documents in their archives:

I have no idea why these files have been labelled 'Parents strongly cautioned' by Wattpad, unless it is assumed that anything in Old French must be dubious.
