Gender what you say re: solicitors has not been my experience at all. Granted they cost a huge amount of money, but have at every turn both my solicitors repeated the mantra that prolonged court cases are to the detriment of the children. It was only once my exes behaviour became incredibly unreasonable that they presented court as an unfortunate course that needed to be taken
They both advised a conciliatory approach on my part towards my ex, pointed me at mediation and also parenting resources on how to navigate the situation with a view to avoiding court if at all possible.
Throwing mothers in jail is counter productive, that sure as shit isn't going to be good for the children, and whilst in some extreme circumstances it may be necessary I think every step should be taken to avoid that outcome.
I am reminded of that case where the woman in Bristol I think it was fled with her son on the eve of a court date, and she only escaped a custodial sentence as the judge consulted the father who just wanted the whole business over and done with.
There ARE laws on the books already to deal with every parent who wishes to cause parental alienation, and another thing you have to ask the question of what the court is there for? It shouldn't be a place you go to punish your ex. I have been treated pretty shittily by my child's mother, but you know what fixating on that and being a good father are mutually exclusive.
The way men can protect themselves in my situation is to squirrel away money in case of court being a necessity and hit the ground running as soon as you become a father. Don't leave everything to the mother to do, be an active and engaged father and build a relationship of significance with your own children, and not by just by being a Disney dad and doing the fun things, but doctors visits, dentists, focus on their education and fund their hobbies. In fact the one of the most significant things is to encourage the bond they have with the other parent.
I agree with you fathers are a lot more significant in child development and outcome than people realise, but that is a case to be made in wider society and the courts are not the place to do that. Broadly speaking I think the courts have more or less the right attitude. More and more men are stepping up to primary care roles with their children, although still not at the level of women. However THAT is where the meaningful change will take place.
