I have a DD age 6. Split up with her Dad when she was 1. WE had to move out of the family home as exDH simply refused to.
He still lives there.
DD visits once a week HOWEVER has never set foot back in our old home because exDH goes to his mothers to stay and the visit takes place there. So the mother does all the feeding, cooking, bathtimes, shopping, pays bills etc his contribution to me is £35 a week.
I do all of the fetching and carrying as he doesnt drive so for 5 years have collected and dropped her off in the car.
I pack her a bag with all clothes etc to go down to stay with.
So basically he pays £35 (he is on about 20 - 25k i would guess) and pops down to his mums to see her once a week.
