I left my ex partner last year, we have two children together aged 11 and 7.
They have his surname and he is named on their birth certificates.
Since I left, my ex has seen the kids a handful of times and has not paid any maintenance. I have asked him to tell me what he can afford to pay - he says nothing. I have threatened to claim maintenance off him and he has responded with text messages saying I chose to leave him, my problem.
I was considering changing my children's surnames to double barrel with his surname and mine, but he will not sign the deed poll forms.
I feel like forcing this through court and just changing to my surname now, purely because he doesn't deserve to share a name with two amazing children who he does fuck all to support both mentally and physically.
I live with my new partner and we are expecting a baby in July.
I would like all of my children to share a common surname.
Am I being unreasonable to change my children's surnames back to my name?
