The couple at the centre of the internet adoption row are due to learn whether social workers will retain custody of the twins they brought into the country.
Alan and Judith Kilshaw are to appear before the High Court, in Birmingham. Then they will fight an application from their local council which wants to make the girls wards of court.
The twins were taken from the Kilshaws' home in Buckley, north Wales, on Thursday by Flintshire County Council.
Mrs Kilshaw, 47, said: "I am still strong and still together and we are still fighting for our children because they are our children.
"But I'm upset at the thought I may never see them again. I might miss their growing up, miss when they turn 18 and when they get married.
"I am hopeful that they will still be with us and if they are not with us physically, they will be with us in our thoughts.
"I will never forget them if I never see them again. They are always in my mind and memory."
The outcry over the case has provoked the Department of Health to speed up the passage of new laws protecting babies being adopted abroad and brought back to Britain.
Health minister John Hutton wrote to the UK's Internet Service Providers' Association (ISPA) yesterday warning that they could be breaking the law if they had illegal adoption web sites online.
Under UK law, only local authorities and voluntary adoption agencies approved by the Health Secretary are allowed to advertise children for adoption.
