High Court Judge Justice Mostyn has ruled on a case where a mother was awarded just £7 per week to support her 16 year old son, despite the father being a multi millionaire.
Mr Justice Mostyn called for the the law around child support payments to be changed.
In this case the father was paying the lowest sum possible because his income was too low - despite the fact that he owned property worth £5m.
The father's 'highly evasive' approach to this case was heavily criticised by the judge, who accused the father of using clever accounting to hide his riches.
In most cases separated parents are able to reach an agreement in relation to child maintenance without the need of involving the Child Maintenance Service (CMS). Those that cannot have to use the CMS and the calculation method used by the CMS can be very limiting.
Estranged fathers with expensive homes should be forced to pay more towards the upbringing of their children, one of Britain's most senior family judges has said. The current system means that those who have low income but have valuable property or investments pay much less in child support - but a judge has said the law is unfair and should be changed. A 2012 reform means that child maintenance payments are based solely on actual income, allowing parents to organise their assets so their contributions are minimal. But Mr Justice Mostyn said sympathetic judges could order more generous lump sum payments to be made to wives disadvantaged by the new rules.
