I am oe of the "lucky" ones - my ex has paid the equivalent of £18 per day for my 2 DCs over the 10 yrs since he left.
He has taken them on holiday 4 times totalling 27 days - which he deducted the cost of the holidays from the maintenance
He has had them overnight a total of 32 days on top of that - for which he has taken them out for a meal most times / takeaway which has been deducted from the months maintenance because I did not feed them,
He once bought them each a new coat - which was again deducted from the maintenance
He has bought them trainers approximately 4 times but again deducted.
Everything else has been paid for by me -travel to school, breakfast lunch, activities swimming lessons, rugby, football , travel to his to drop them off, all clothes shoe, treats etc., school laptops, birthday and christmas presents etc etc
One child is now 6ft 6 and the other fast heading that way- the new bed to fit said child in and mattress damn near wiped out half the years payments! Shoes are now a size 14 - they do not come in cheap, trousers are custom made - think size 30 waist and a 38 inside leg!!
Generally the RP pays far more of the childs costs even if the DF does give something. Hounding is not what have I done but i have heard mutual friends who are also divorced saying their EXs cashed in afte they had done all the work - bitterness is rife.
COI: I paid him out of the house, car and furniture - I got the DCS( best bit) but def did not cash out.
