He does work but he has debts. The property is rented and in her name. She is applying for benefits and has insisted he pays 50 percent of the rent and bills until the benefits are awarded. He has come to live with us (his parents) and we are not charging him rent, otherwise he wouldn't be able to cover these costs and his own living costs.
Hi again - as an update to my answer below I have just found out that the rented property is in both their names.
The biggest problem is that she's preventing him having access to his son for more than 9 hours a week. He is a good and wholly dedicated father and this situation is upsetting him (and us the grandparents) hugely. Thank you
He earns around £270 per week after tax, and from this is giving £100 a week to the mother (this is half of the household bills and rent)
His work pattern is variable as he works in a restaurant and so often has to work late shifts, and only infrequently gets more than one day off at a time. He has asked for more contact than one day and one evening a week.
He would like to be able to see his son on his both his days off during the week and also two evenings a week, to be able to put him to bed.
From recent discussions he has had with his ex-partner, the impression he is getting is that she is limiting his access to his son as a 'punishment' for his failings as a partner. We feel this is not a healthy or useful way to allow access to his son and for his son to be able to relate to his father.
