The Supreme Court has been considering a petition on the issue filed by gay right activists and on Wednesday it issued an interim order allowing for same-sex couples to register their marriages pending a final verdict.
Gurung said about 200 same-sex couples were expected "to come out openly and register their marriages".
In Asia, Taiwan is the only place that recognises gay marriage, though pressure is building for reform in Japan, Thailand and South Korea.
Since then, some same-sex couples have held unofficial weddings and gay pride parades have been held in the capital, Kathmandu.
"We will now approach the authorities to formally register our marriage," Gurung said, referring to her partner of nearly a decade, Surendra Pandey.
