Borten was born in Flå in the municipality of Melhus in Sør-Trøndelag, and was educated Agriculturist from the Agricultural University of Norway in 1939.

After his retirement from politics, Borten continued to speak out on issues such as nuclear disarmament, clandestine surveillance, and the controversy on Norway's relationship to the European Union. He served on the boards of several public banking organizations. He earned a reputation for being an engaging and somewhat contrarian figure in the Norwegian political landscape. Borten died in Trondheim at the age of 91.
