Husband was paying exw £380 a month for his two DS. Access was set out years ago that kids stay over 1 night on a weekend. For over a year an informal agreement was made that they also stay 1 night midweek too, which has been continuing fine.
Recently CSA has increased to £500 a month, after ex has been to csa. He was paying what csa has told him to pay. He called csa to advise about the extra night he has them and they said if she confirms this info then a new calculation will be done. She then messaged my husband and threatened to stop all midweek visits and she will not confirm the extra night he has his children. He has messages to confirm Thjs and messages to confirm his children do stay over an extra night. Is there anything he can do to with csa to look into this calculation again as the amount of nights are not correct.
