DH and I are separated. DC live with me. 1 stays overnight once a week with DH, though this is new. He pays me Child Maintenance each month at a rate a little lower than gov.uk say but I earn more than him. We both work. I pay all the childcare costs. He has just been made redundant and has been paid a lump sum. Should he up his payment as a percentage of that, or just pay the same? I'm aware that next month and until he gets a job he will have no income. So the lump has to pay his rent and bills for an unknown period. I suspect this may be longer than he anticipates. He will probably spend it on crap anyway and be in the shit quite soon. I am expecting him to stop payments completely very soon. If this happens, what do I do?
