Removing Initial

Hello Sir/Madam, Ex parte divorce decree has been pronounced 2 years before (My friend did not contest and her husband got ex-parte decree). This guy left her when she was 10 days pregnant and did not show up until delivery. After 40 days of child birth , he showed and created unwanted nuisance and ended up filing a divorce petition. The girl was not ready to contest as she was weak due to delivery and then decided to leave it as it is after consulting a lawyer. Fast forwarding to 2021, the baby is 3 years old. My friend wanted to remove the initial (first letter of his name ) from her baby's name ? is there any future implications for the (girl) baby if the initial is removed ? Also, is it advisable to remove fathers name from birth certificate ? Should there be any problem for the child in future for education/her marriage etc., .? Please advise. This guys had hardly holded the baby for 25 mints in 2 different days (after 40 days of birth). After that he never tried to visit or enquire about the baby or the wife. Looks like he is married to another girl and got a boy baby now. Will this guy in the near future claim my friend's (girl ) baby. ? She is single and started working again after maternity break. She is very much worried about him being torturing again in future by claiming the baby. She has not got single penny from him so far. In fact , even before divorce he has not paid anything for the pregnancy checks. It was all managed by my friend and her parents. Finally is it possible to get a written statement from this guy that he will not intervene in her life and her child's life in future ? Thank you. (Do not wish to specify name)
