According to her family's lawyer, Iskandar Zulkarnaen, Wanipah was convicted in April 2011 of smuggling 992.72 grams of heroin into China through Xiaoshan Airport in Hangzhou in December 2010.
Wanipah was sentenced to death, with a grace period of at least two years before execution. The Indonesian Foreign Ministry informed her family of her situation in August 2011.
Iskandar, speaking for her family, said that his legal team planned to take this urgent matter to House of Representatives Commission IX, which oversees manpower.
He also plans to seek help from the Foreign Ministry and Office of the Coordinating Political, Legal and Security Affairs Minister to get a stay of execution from the Chinese authorities.
Wanipah's family said they hoped the government could provide adequate assistance and save their daughter's life.
"I hope Pak Jokowi can help resolve her case," Rusmini, Wanipah's cousin, said recently, referring to President Joko "Jokowi" Widodo.
"At the very least, her sentence could be reduced," said Wanipah's mother, Nusriah.
Iskandar said that Wanipah was likely a victim of human trafficking as there was evidence that her travel documents had been forged.
On her family card, Wanipah is recorded as having been born on April 17, 1987. However, on her passport, her date of birth is May 1, 1978.
"It is possible that she had fallen victim to trafficking. We can see it, at least, from the false data," Iskandar said.
Based on data from the Foreign Ministry, 299 Indonesians are now facing execution overseas, 57 of whom were sentenced to death for drug offenses.
At least 467 Indonesians have been executed abroad, including 168 in Malaysia, 28 in Saudi Arabia, 15 in China, four in Singapore, two in Laos and one in Vietnam.
Most recently, migrant worker Siti Zaenab was executed last month in Medina, Saudi Arabia, after being sentenced to death in January 2001.
She was arrested in October 1999 for stabbing her Saudi Arabian employer to death. Siti, from Madura in East Java, had worked in that country since 1997.
Just days after Siti's execution, another migrant worker, Karni, was executed in Saudi Arabia. She received the death penalty in 2013 after killing her employer's child in 2012.
The executions were carried out without prior notice from the Saudi Arabian government and despite requests for pardons filed by the Indonesian government earlier this year.
