In the same year, he married Susan Robinson, the niece of John Robinson and became a director and the solicitor for the Bank of New Brunswick. From 1826 to 1834, he practiced law in partnership with his brother Neville. Parker served as attorney general in 1828 following the death of Thomas Wetmore and became solicitor general later that year after Charles Jeffery Peters was named attorney general. He was also named judge commissary in the vice admiralty court. In 1834, he was named puisne judge in the province's Supreme Court. In 1865, he was named Chief Justice but died a few months later in Saint John.
