He studied at University of Leyden, and was admitted advocate 8 June 1669.
He was appointed lord of session November 1674, when he took the courtesy title of Lord Reidfurd. Foulis was elected commissioner for Edinburghshire on 20 January 1685, was a supporter of the extreme measures of the government, but continued to sit after The Glorious Revolution, "until his seat was declared vacant, 25 April 1693, because he had not taken the oath of allegiance and signed the assurance". After the death of William III he was made colonel of the Midlothian militia, and sworn of the privy council (1703).
He opposed the union.
Foulis married Margaret, daughter of John Boyd, dean of guild, Edinburgh, by whom he had several children. The chief papers were published, with notes by him, or compiled under his direction, and exhibit some details as to Scotch aristocratic life and customs of the period ("An Exact and Faithful relation of the Process pursued by Dame Margaret Areskine, Lady Castlehaven, against Sir James Foulis, now of Collingtoun," Edinburgh, 1690).
Among the Lauderdale Manuscripts are various official reports and addresses to Charles II and the Duke of Lauderdale, to which the signature of Foulis is appended.
