Chou Shu-Chi and Wang Shu-Yi have been together for 15 years and have decided to start a family four years ago.
When their twins were born, Chou was recognized as the legal guardian since she is the biological mother of the children. The couple then tried to recognize Wang as co-parent even if Taiwan does not allow the adoption of children from a partner.
But their attempt failed. They decided to sue the government. They want that Wang is recognized as the stepmother of their children.
"We've been together for 15 years and we have raised our children for more than three years," Wang told the Taipei Times.
"We are in a stable relationship and are a happy very stable family. All we seek is the legal recognition of this, so we can be a family, not only in real life but also in the eyes of the law."
We don't known yet when the court will hear the case.
