More may be added to the earlier biography.
In 1418 Vivian quarrelled with John Trewint*, but the cause of their dispute, which was submitted to the arbitration of Sir John Arundell I* of Lanherne, is obscure, as are the details of Arundell’s award.
The respect in which Vivian was held by his neighbours in spite of his unlawful dealings is attested by his inclusion on Christmas day 1401 among the witnesses to a property settlement between members of the Moyle family (kinsfolk of the Trenewiths of Earth) alongside the prominent lawyer Richard Respryn†.
On other occasions, Vivian found himself before the King’s courts on charges of not paying his bills to two London cloth traders, the mercer Nicholas Drayton and the draper Benedict Harlewyn. The outcome of the dispute with Drayton is unknown, but in the case of Harlewyn Vivian claimed that his opponent had forced him to seal a bond for 73s. 4d. under duress while keeping him imprisoned at Bodmin.
Vivian’s widow was entrusted with the execution of his will, and was for some years after his death occupied by the settlement of her former husband’s affairs.
