Nadina Abarth-Žerjav was the daughter of the Slovene politician and lawyer ministerGregor Žerjav and his wife, Milena née Lavrenčič. Her younger brother was Borut Žerjav, a journalist in Paris after the second WW. Her twin sister was Tatjana, who died young from tuberculosis. Nada Abarth Žerjav spent her early childhood in Graz and Ljubljana. Because her father and politician Žerjav was preventively arrested and imprisoned during World War I in Ljubljana Castle and in Graz by the Austro-Hungarian authorities for his "notorious pro-Serbian attitudes", she lived some time with her grandparents.

She was wounded during the war. On November 28, 1949, she was married to Carlo Abarth, the well known Turin–Automobile-Industrialist. Nada Abarth-Žerjav and Carlo Abarth met in 1944 at Lake Garda. They may have even met during the war in Ljubljana. Nada Abarth supported her husband during the founding period of the Abarth-works as later on in every possible way. She initiated contact with Tazio Nuvolari, which became important during the first years of the existence of the Squadra Abarth. She spoke seven languages which enabled her to engage in public-relations in foreign countries as well.
