*DH pays his maintenance. He offered more but because of past problems with the mothers capability to tell the truth needed reassurance that SD was his. So, when she refused this and went to the CSA, he had to pay for a DNA test instead.
When she rarely if ever, showed up for contact, DH had no option but to take her to court, fir which he had to pay quite substantial amounts in fees and charges. She showed up, agreed to everything and then ignored the lot.
More fees and advice, back in court six weeks later. She 'apologised' as it was unfair if her to have yo di this 'short notice'. This was August, she was ordered to endure enough contact took place that staying contact took place by October. Back in court November, no staying contact, she cried and her mum shouted DH down everytime he tried to speak. Ordered to allow staying contact, but to begin with full days.
Back in court January, still no staying contact, ex has decided this might start in February. Case discharged with a reasonable contact order. To start with one night and buildup.
Two and a half years later, still at one night per week. DH will have to pay yet again to get increased contact with SD, who has asked her mum for more contact. He gets max of a weeks notice when she takes her in holiday, so not only misses his one night a week contact, but stops us from arranging anything too. An increase, say of a one-off two night visit will only ever be approved at a few days notice, so either way we can't plan anything.
Two weeks ago this impoverished single mum left her daughter without telling DH or offering increased contact. She didn't come home when SD needed lifesaving surgery, refused staying contact as she didn't trust DH to give SD her medicines (left her with grandma while she went out partying).
DH will have to go back to court (paying yet again) in order to get more contact. What will happen to the mother? She'll cry, say she didn't understand, promise to comply, ignore the orders as much as she can get away with. She'll not face any sanctions, they simply wouldn't do it. Its the same with the CSA, she was supposed to tell them when staying contact started, six months later we told them instead. We couldn't tell them sooner because she would use it in court to refuse increased contact.
Everyone loses in these cases. There needs to be a overhaul, a presumption of 50:50 and zero maintenance.*
Exactly the sort of case where you'd like to think these sanctions would be used. And anyone who thinks this sort of thing is rare is very sadly deluded.
