Child maintenance service should cap pension contributions

It is ludicrous that non resident parents are currently legally allowed in the UK to pay as much money as they want into a private pension for themselves to use later in life, so that by doing this it reduces their gross income so that the child maintenance payments calculated for them to pay to their child/children growing up is a lot less. This will have a huge impact on a lot of children growing up in single parent families and is simy wrong. Please sign this petition for this to be looked at and changed. Thankyou
