A Redcar woman on death row in Bali for smuggling drugs will challenge the sentence imposed by an Indonesian court.
Lawyers say 56-year-old Lindsay Sandiford has given notice of her intention to appeal against the sentence at the country's highest court.
She lost her appeal over the UK Government's refusal to fund her legal bid.
A spokesman for law firm Leigh Day, which is representing Sandiford, said: "Lindsay's lawyer has now given notice of her intention to appeal to the Indonesian Supreme Court against her death sentence.
"However, after the British Government's refusal to help, she still lacks the funding she needs to ensure she has a lawyer for the appeal itself. She is now reliant on the generosity of members of the British public to ensure this can take place."
The notification to appeal was lodged in Denpasar, Bali's capital. Full documentation outlining the grounds of the appeal must be submitted to the Supreme Court within 14 days.
Lawyers for British grandmother Lindsay Sandiford today launched an urgent new legal challenge over a UK Government refusal to fund her appeal against a death sentence imposed by an Indonesian court after she was found guilty of drug smuggling.
The Foreign and Commonwealth Office refused as a matter of Government policy a request to pay for "an adequate lawyer" to represent Sandiford, 56, from Cheltenham, at the Bali High Court appeal.
She was sentenced to death by firing squad by a court in Bali for taking #1.6 million of cocaine on to the island.
In January, the UK High Court upheld the Government's stance of not providing legal funding for British nationals arrested abroad, even in exceptional circumstances.
After the High Court gave its decision, Sandiford received a private donation of over #2,500 that enabled her to be represented by an Indonesian lawyer at the subsequent Bali appeal.
Having lost that first appeal, she is now in a race against time to raise money to take her case to Indonesia's Supreme Court in Jakarta.
Three judges in the UK Court of Appeal are being asked to overturn the High Court decision on funding.
A grandmother from Cheltenham, who's facing execution in Bali, has told how she is "desperate" after running out of money to pay a lawyer for her appeal in just over two weeks.
Lindsay Sandiford was sentenced to death on drug charges by a Bali court on 22 January this year.
In an open letter published by human rights charity Reprieve today, she said:
"I am sitting in my death row cell here in Bali. Yes, I feel depressed. Yes, I know I have been stupid. Yes, I want to say sorry for what I have done - sorry to the British people for the shame I have caused and - more than anything - sorry to the people of Indonesia. And yes, I am totally humiliated.
"I don't want to beg. I'll accept help, because I'm desperate and I don't know where to turn.
"I don't have the money to pay a local lawyer, again. I suppose, in the grand scheme of things, it's not very much money. The last appeal cost about £2,600. This time, in the Supreme Court, it will be about £8,000.
"If I really were a rich drug dealer, it would be no big deal. But I'm not, and you might as well ask me to pay ten million dollars."
Tomorrow Ms Sandiford's lawyers will go to the English Court of Appeal to appeal against the FCO's decision not to help fund her lawyer.
A woman from Gloucestershire has lost her appeal against her death sentence for drug smuggling in Bali. Lindsay Sandifrod from Cheltenham was found guilty in January of smuggling 1.6 million pounds worth of cocaine.
It's a decision the Government has described as disappointing, while the foregin office reiteraited the UK's opposition to the death penalty. Jonty Messer reports:
Human rights organisation Reprieve has previously said it believes there is evidence to show that Sandiford was threatened and coerced into acting as a courier.
Indonesia has an estimated 114 prisoners on death row. Most of the more than 40 foreigners among them have been convicted of drug crimes, according to a March 2012 report by Australia's Lowy Institute for International Policy.
Five foreigners have been executed since 1998, all for drug crimes, according to the institute. There have been no executions in the country since 2008, when 10 people were put to death.
