Fifty-seven prosecutions were brought by East Sussex County Council against parents who have ignored their child's absence from school and have failed to co-operate to resolve the problem.
During April, May and June cases have been brought by the council's Education Welfare Service at courts in Eastbourne, Hastings and Lewes resulting in a total of £4,590 in fines and £3,270 in costs.
They are part of the council's on-going drive to improve school attendance and hold parents to account.
In Eastbourne 21 cases were heard by the Magistrates Court, resulting in a total of £1,650 in fines and £1,100 in costs.
Two parents whose son failed to attend school at all between November 2007 and February 2008 pleaded guilty and received a 12-month conditional discharge.
The cases were brought by Education Welfare Officers who work hard to support, help and advise parents if they are having difficulty with their child's attendance.
Councillor David Elkin, the county council's lead member for learning and school effectiveness, said, "Most of the work of the Education Welfare Service is involved with positive schemes to educate young people about the importance of school and their education, and also in actively helping parents tackle problems they may have with their child's attendance.
"It's only when a child is repeatedly absent and the parent ignores the problem or refuses to co-operate with us to tackle the problem do we resort to this kind of action through the courts.
"Fortunately the vast majority of parents appreciate the importance of an education to their child's future opportunities and life chances."
