In 1974, Kirchner met Cristina Fernández, three years his junior, and they quickly fell in love. They were married after a courtship limited to six months by the political turmoil in the country. At the civil ceremony, Kirchner's friends sang the Peronist song "Los Muchachos Peronistas". He graduated a year later, returned to Patagonia with Cristina, and established a law firm with fellow attorney Domingo Ortiz de Zarate. Cristina joined the firm in 1979. By the time of Kirchner's graduation and move to the Patagonia, Juan Perón had died, his vice president and wife Isabel Martínez de Perón had become president. Isabel Perón had been unseated by a coup d'état which installed a military government. The Kirchners worked for banks and financial groups which filed foreclosures, since the Central Bank's 1050 ruling had raised mortgage loan interest rates, and also acquired 21 real-estate lots for a low price when they were about to be auctioned. Their law firm defended military personnel accused of committing crimes during said war. Forced disappearances were common during the Dirty War, but unlike other lawyers of the time the Kirchners never signed a "habeas corpus". Julio César Strassera, prosecutor in the 1985 Trial of the Juntas case against the military, criticized the Kirchners' lack of legal actions against the military, and considered their later interest in the issue a form of hypocrisy.
