Since divorcing in 2011 I have been paying Child Maintenace ( the amount is above the CSA guidance figure ) and spousal maintenance as at the point in time there was a 'need' for £125 pm. The ex wife was working 3 days a week and the terms of the spousal was that it would end when she returned to work full time. 4 years on she has had several promotions and is now earning an extra £400 net a month but only working 4 days week as she knows she will still get an additional £125 a month from me as long as she doesn't go back full time.. In addition to the child maintenance I also fund all their school uniforms and other clothing costs, birthday parties, school trips away etc.. Is it reasonable to still demand spousal maintenance when your salary has increased by over 3 times the need for it?
