Georgia Beesley said her mother, Vicky Pryce, told her that Chris Huhne had nominated his then-wife as the driver without telling her, and when it arrived, she was already named as the driver.
"I know she felt pressured into signing the form," she said.
Mrs Beesley said the issue resurfaced as Huhne lost his licence soon afterwards when he was caught talking on his mobile phone, telling Southwark Crown Court:
He lost his licence anyway that summer and mum had to drive him whenever he needed driving. A lot of comments were made around that time, 'I have got to drive you anyway, even though I took the points'. There was quite a bit of resentment.
She said her mother was "very upset she had had to do something she really didn't want to do and the outcome was exactly the same".
