Yeah - it does not sound very normal.
I assume you have done your intake session for mediation then? That would be a good place to discuss with the mediator some of the concerns you have and the behaviour that you have witnessed. In the discussion (intake session) it is a good idea to try and show the mediator the impact on the children and concerns you have with respect to the children.
Remember the mediator is exactly that (it's someone to help the negotiation not someone to make a judgment on the merits of your case). There are two stories and their job is to bring the parties closer to an agreement. So it is a good idea to formulate in your head as to what your absolute "worst outcome" is and negotiate for anything better. I assume you will go to mediation asking for 50 / 50 care or more? It is often a good idea to go with multiple different care options which shows that you have given thought to the kids and other parents situation and show a willingness to negotiate and look for options. Bear in mind the impact this might have on the kids being apart from what is their "primary carer". As much as it sounds like she has not acted in a very good manner with respect to the kids she has still been their carer and it is what the children "know". A change to this will likely be disruptive. A gradual re-introduction into the other parent's life is often preferred once matters where there has been minimal to no access go to court. Playing the patient long game is certainly prudent advice.
Re: the other parent being lonely (and saying so) and keeping the kids out of school - Do you have evidence of this? I believe that this is something the courts will be critical of and deem as a risk factor to the children. Putting your own interests before the children's is not on. With evidence such as this (compromising your children's education to satisfy your own loneliness - sounds like borderline abuse to me) you may want to look for obtaining orders where care is primarily placed in your hands. I'd suggest you seek legal advice with respect to this.
Good luck
We are due to have our intake session next week. We already know she will ignore it and not show up. Last time my partner tried this she didn't show up and ignored all letters and phone calls. He previously got his certificate to go to court. When he spoked to her and said he would proceed she hurled abuse, made all sorts of threats dragged the kids out of the house and told them that daddy was trying to take mummy away from them and they would never see her again. The kids started to cry and said daddy please don't, pf course it was see! See what you are doing to the kids do you really want to be the person who puts them though all this, do you want to be the parent they hate. My partner is not a fighter and hates conflict so he backed down. (this was before we were together so he believed her threats and didn't think the courts or system would help in anyway)
As much as want to apply for a live with order I know going in all guns blazing will not help us. Mind you I have never meet these little humans as her response was they do not need to know me or my children and that my partner needs to focus on "His Family" and her children don't need to be part of it.
Yes we do have evidence of why she kept them home, we have a recording of one of them telling my partner "We didn't go to school this week daddy". when he asked why were you sick he replied "no mummy said we could stay at home because she didn't want to be lonely". "I told mummy I wanted to go but she said no"
Once we get to court, my intention is to submit a notice of risk against the mother due to mental health. I will be requesting that the mother attend an approved phycologist to asses her separation anxiety and ability to provide adequate emotional care to the children.
Since they have not had an overnight stay or spent anytime alone with their father I will be suggesting a staged approach and break each section down by school term. (Bare in mind we are in NSW she is in ACT) Yep my partner has to drive 3 hours every 3 weeks to spend 2 hours with his kids with her present. (his parents and brother live in the ACT)
Term 1: The children shall spend time with the father from 8am to 6pm every second Saturday and Sunday (children get returned at night to her) Focus on building the relationship and bond
During school holiday the Children will spend time with the father (either first or second week) each day from 8am to 7pm with 3 overnight stays included. (facilitated at his parents house)
Term 2: The children shall spend time with the father from 6pm Friday till 6pm Sunday (facilitated at parents or uncles house)
During the school holidays the children shall spend time with the father on a week about basis commencing at 6pm Friday. (Facilitated at the fathers home)
Term 3: The children shall spend time with the father each alternate weekend commencing 6pm Friday till 6pm Sunday (Facilitated at the father home address) Change over shall occur Marulan McDonald's
The children shall spend time with the father on a week about basis facilitated at the fathers home address, change over shall occur at Marulan McDonalds
(Christmas day will also come into this section but that's an easy one year on year off)
I think this way if we show the judge we are willing to take a staged approach we are focusing on what is in the best interest of the children as we don't want them to all of a sudden just be told okay your coming with us for the weekend. They are only little so it would be very overwhelming for them.
