His brother Martin Vaus, later Dean of Ross, was at Paris with him.
[2] On 8 May 1456, he was provided to succeed James Inglis as Dean of Glasgow Cathedral.
Unfortunately for Vaus, Spens' translation to Aberdeen was not effective, and while Spens was indeed successfully translated to Aberdeen in the following year, it was Ninian Spot, not Vaus, who on 15 December 1458 got the new provision to Galloway.
The reasons for this change are not clear, but Thomas never became a consecrated Bishop of Galloway nor did he ever attain another bishopric.
[5] This provision involved him in litigation with one David Balfour, who was said to have been in possession of the deanery on 25 June 1463.
