The size of Ms Skinner’s claim has not been revealed, though it is very significant.
“The sticking points are almost every element of her claim,” said Mr Goldberg.
The biggest contested issues include her loss of earnings and future care costs.
The Department for Business and Trade recently took over responsibility for delivering redress for sub-postmasters whose convictions were overturned by the courts, including Ms Skinner’s case.
A spokesperson said it did not comment on individual cases, but that it took every effort to make full and fair offers. An independent dispute resolution process was available to all applicants who were not content with their offer, they said.
More than £1bn worth of compensation has already been paid out to more than 8,000 victims.
The bulk of these payouts has been in the form of uncontested fixed payouts, either £75,000 or £600,000 depending on the severity of the case.
