Sorry, there seems to be two threads going on here. Can I possibly request that a mod separate the posts into two threads?
can I file for full custody since she won't let me see my daughters
Gabe Jae, state police cannot intervene in family law matters because it's not within their jurisdiction to do so. Family law is a federal matter and a civil one (not a criminal one), thus, only federal police can act and only if ordered by the court do so. I advise against excessively involving the police - it's not often welcomed by the court and it's a waste of police time and resources if there is no genuine fear for a child's safety. On top of that, there is a proper avenue to follow for contraventions of parenting orders, and state police have no part in that process. You must first attempt mediation then file an application for contravention orders if mediation fails.
As for father's/mother's rights, parents don't have any rights under the Family Law Act 1975, only children do, provided under section 60B. That right is to know, spend time and communicate with both parents and other people significant to their care on a regular basis insofar as it's in the child's best interests to do so. Those are the rights the court will uphold in family proceedings, rather than perceived "parents rights".
Can you file for sole parental responsibility? Yes, but will you get it? Unless you can prove the children are at risk of harm under the current arrangement, probably not. There's a legal presumption in the Family Law Act that both parents have equal shared parental responsibility for all major long-term decisions relating to a child's care, and that presumption can only be removed by order of the court following successful rebuttal to the presumption. Orders for sole parental responsibility are extremely difficult to get, in this day and age. Your time and money would be better spent aiming to uphold the child's rights, which is to have a meaningful relationship with
both parents, not just one.
I can't say I've found the court to be biased against fathers, provided they choose not to act as though the court is biased against them. Family law judges are pretty switched on - they are very good at telling the difference between a party who is acting in the child's best interests, and a parent who is just out for vindication disguised as the child's best interests (which, as a matter of interest, is quite often the mother). Thus, it's important to be the parent that always puts the child's best interests first, even when the other parent refuses to do so. If you make effort to minimise their exposure to conflict and make effort to communicate with the mother in a reasonable fashion, the court will have to turn somewhere else to find the problem. If it's not you, it's her, if that makes sense.
Anyway, I hope this helps and apologise if I seem a bit blunt. As a demographic definitely still recovering from years and years of being treated like the 'lesser parent' in court, I try to encourage fathers not to see themselves as being the lesser parent because amendments in 2006 definitely changed that dynamic to their benefit. Especially now, fathers are being treated as fathers should be treated - as equally important. But it's just harder to establish yourself as that when you get distracted by the frustration of slow court proceedings, a refusal by police to act (only because they simply can't in a legal sense, not because they don't support fathers), and a mother who seems to be freely playing the 'superior parent' role with no retribution.
At the end of the day, the court doesn't like parents who withhold kids, and judges have no hesitation at all in telling parents exactly what's what. Just be patient and follow the right procedures.
