Thanks1. Get dad to send her at text message.
Dear ex,
I'd like to see (child's name) next weekend from Friday through until Monday morning. Does this suit you?
If she doesn't respond. Do nothing. Do not get into a text message war with her... Don't write anything that could in anyway be percieved as threatening... Or he will have an avo on him in no time.
2. Get mediation started. Relationships Australia - Good start.
3. Depending on how the text message goes and how long he wants to wait... He could consider an appointment with a solicitor - But at $500 an hour... Holding off to see how mediation goes might be an idea.
