Establishing a lucrative practice on the civil side, he was bestowed the honour by the then British Government of being appointed a Queen's Counsel in 1947, and later served as a Judge of the country's Supreme Court from 1951.

With the enactment of Sri Lanka's Citizenship Laws after the Country's independence in 1948, Nariman Choksy found himself (and a few other well established settlers of Indian origin) as becoming "stateless".

Upon this being brought to the notice of the incumbent Government, a law was enacted by Parliament in 1950 under which Nariman Choksy qualified for citizenship as a "Distinguished Citizen" of the Country.

From boyhood, he imbued the legal atmosphere in his father's Law Chambers and being called to the Sri Lankan Bar as an Advocate in 1958 rapidly established himself in a leading practice in the civil courts of the metropolis of Colombo.

The Sri Lankan Constitution makes provision for a limited number of such appointments, so that the Professional and Academic communities could find representation in the Legislature without having to contest at elections.

The third son, Vishtasp, has taken to the family tradition of the Law and practices as a Lawyer in Colombo, the third generation of Choksys to excel in his chosen profession.
