I have looked through quite a few threads on this topic but didn't find a similar situation. My son is almost 10, he has had no contact with his paternal grandmother since he was 1 and prior to that she saw him less than 20 times, mostly due to her being too busy or uninterested. His father and I have an amicable separated relationship and he has regular visitation with our son. For almost a year and a half after the last time she saw our son, I was located at the same address and was easily contactable yet no attempt at contact was made during that time. I moved away with our son when he was almost 3 to QLD and have returned to WA in the last year. During the time away, his father's visitation and contact were maintained. I also maintained the same mobile phone number since before my son was born so she has always had a way to contact our son but has never attempted it. To date our son has not seen this woman in over 8 years. Today I received a Facebook message from her out of the blue asking me to contact her regarding mediation for contact with our son. I am quite upset over this as there has been no prior contact or request to see him, just a jump straight to legal procedure and my son wouldn't recognise her if they crossed in the street. There is a lot of backstory but ex refuses to see or contact his mother due to some atrocious behaviour on her part during his childhood. She has no relationship with his new child. I understand that the child has a right to maintain contact with their extended family which is why I maintain contact for our son and my other children with his step-grandparents (who are biological grandparents to my other kids - their father and I are also separated) who are very involved in his life and have been since he was a toddler. I have concerns over her behaviour and past addiction history. She has been known to drive drunk alcohol and/or intoxicated. I don't know if this is still the case, as like I said I have had no contact with her but my ex has told me that he has doubts as to her rehabilitation. He has requested that I send her a message denying contact with our son and that I request that she not contact me again. We will be presenting a united front should it go to family court requesting that she has no contact with our son, but I am worried about potential outcomes. I genuinely doubt that this woman can have a positive influence on our son and given that his father still struggles with the emotional wounds that she inflicted on him, I worry about her potential negative influence on our boy.
