I have applied for child maintenance after having my daughter and her dad having no contact cut a story short he has asked for a DNa and we are in the process right now but I feel like maybe he is prolonging things so he doesn't have to pay me yet I'm not 100% sure but I think he is as I have booked my daughters already and he hasn't booked his, does anybody know if they're is such thing as back date or does he just pay from the first week things go ahead, also if I choose to get him to pay through no contact and through cms I know that costs him more but will they deduct it from my Cm too, he has tried to play me as he tried to come back to me just after I applied he got in contact after not being in contact in the whole three months my daughter was born I'm not sure what he we trying to do but I think he was trying to do something.
