I asked the csa to get the maintenance for me and glad i did now because although my ex has given me money the last 3 months this month he's decided he cant afford it this month because he has his car to services etc, the are going to do a deduction of earnings. They can take 40% of his wages back pay and also the normal 20% on top. Although doesnt help me this month as they yhave said it will probably be another 6 weeks till i get anything.
