Carr faces court over benefit fraud.
The former teaching assistant was likely to plead guilty at Nottingham Crown Court.
Carr, who is serving a three-year jail sentence for conspiring with Huntley to pervert the course of justice, faced a string of charges of deception and attempted deception.
They relate to claims for housing benefit, income support and Jobseekers' allowance. Carr, from Grimsby, was also accused of lying about her qualifications in job applications.
One of the jobs was as a classroom assistant at St Andrew's Primary School in Soham, Cambridgeshire, where Huntley's victims, Holly Wells and Jessica Chapman, were pupils.
Huntley, the former caretaker at Soham Village College, was jailed for life at the Old Bailey in December after he was found guilty of murdering the 10-year-olds. Carr, 27, was jailed for three years but was cleared of two charges of assisting an offender.
In March Carr was transferred from Holloway Prison to Foston Hall in Derbyshire in preparation for her expected release on licence in the next few days.
Fellow inmates staged a protest about her presence there and arrangements for her release have been kept secret amid fears she could be attacked.
But there has been widespread speculation about where she will live. The Australian government has denied any plan to move Carr there following speculation that police, prison and probation officials had tried to persuade her to adopt a secret identity in Australia.
Carr is known to be against the idea of moving abroad and wants to return to live with her mother in Grimsby.
Another option is to place her at a secret address elsewhere in the UK and give her a new identity.
