Families fight to have surrogate child's dead mother recorded on birth certificate

This is the story of Paige - the only child in New Zealand who has been stripped of her mother's identity on her birth certificate. Instead of her mum's name, it simply says "not recorded".

It is a surrogacy birth dream that has become a nightmare - and now the families involved are fighting to make it right.

Eighteen-month-old Paige is just like any other kid, except for this - officially, Paige has no mother. Her birth certificate just says "not recorded".

"'Not recorded'. When that turned up in the mail, it was worse than having nothing written there. "It was a bit of a kick in the guts," her father Kyle says.

It hurt, because Paige has a mum. Kyle's wife - Kat.

Paige's life started like so many others. Kyle and Kat fell in love and got married.

"She really, really wanted to be a mum," Kyle says.

But for Kat, pregnancy would be unsafe. She was born with cystic fibrosis which destroys the lungs. And although she had a lung transplant, carrying a child was too much.

"Surrogacy seemed to be the most logical next step for us," Kyle explains.

Surrogacy would mean IVF - in vitro fertilisation. This means taking Kat's eggs, adding Kyle's sperm, creating an embryo and transferring that to a surrogate mother.

Their friends Renee and Josh were keen for Renee to carry the baby.

"We thought - why not? We'd finished our family," Renee says. "I just wanted to help someone. I just wanted to give that."

"Everyone deserves to be a parent. Everyone deserves to be a parent," Josh adds.

Surrogacy required ethical approval - but with her doctor saying Kat's chances of living at least another 10 years were 92.6 percent, it was approved.

"She was so happy," Kyle says.

And when Kyle and Kat's embryo was transferred to Renee, the pregnancy worked first time.

"It was massive. Massive," Kyle says.

"We were just stoked that it worked first go. It was meant to be," Renee says.

Then - everything changed.

"Just chronic rejection of the transplant, randomly - for no real reason," Kyle says.

Kat was dying - as the baby was growing.

"Having those conversations with your wife who is 37 is pretty hard in regards to what does she want me to do about life and the baby," Kyle says.

Surrogate births rely on an after-birth adoption happening. An 'intended mother' had never died ahead of birth before. They knew there would be problems with the birth certificate.

"I promised her that I would figure something out," Kyle says.

Before she died - Kat chose a name, after a dog she got aged 15.

"Paige. I want to call her Paige. And she said 'you know, I had Paige before I met you, to look after me, so I am going to leave Paige to look after you'," Kyle says.

Kat died before Paige was born - and then came the surreal adoption ceremony.

"It wasn't how it was meant to be," Renee says.

Under the 1955 law, an adoptive mother has to be alive. That's why Kat is 'not recorded'.

"All Katherine wanted to be was a mother. And she deserves to be on that birth certificate," Renee says.

Josh has taken up the fight for Paige to have her mother's name recorded, even writing to the Prime Minister. But so far nothing, nobody will help.

"Paige doesn't deserve that. She deserves to have that. Her birth certificate is her identity," Josh says.

"Just put the name on the piece of paper," Kyle urges.
