Child Visitation advice or waive right in MCD

I & my wife are planning for Mutual divorce due to lack of adjustment & very high expectations in relation from my wife side but she is insisting me to sign divorce papers with irrevocable & permanent waiver of access of my child (son 8 years) as condition which I am not agreeing. No case is yet filed in court. Also she is planning to put condition of change of surname & deletion of father name in MCD. I have no money settlement problem for MCD as per my position but I am feeling very much guilty within self if i agree for waiver of child access right. My relatives are advising me to sign petition with waiver of child access because my wife will take revange either from my son or from me in court due to false allegations cases. whethet it will impact my child future if i will meet with my son or whether my life will become useless in court for many years. kindly advice & consider it case of member of your family
