Just a general question really. Dad makes around £250 per week after tax. No other contribution other than CM. Doesnt buy anything else for DD. Doesnt take her overnight. How much child maintinence would you say he should pay?. I'm trying not to go down the CMS route but he refuses to tell me his exact earnings to do a proper calculation and tells me he earns £250 a week. I think its probably more to be honest as he is in a really good job. Dont want to say on here as it could be outing. What would you ask him to contribute?
