What is the provision for child maintenance in Mutual divorce

I am going through mutual divorce after 10 years of marriage. Have one girl child who will stay with my wife and she will have the full custody. I am giving money and flat as one time settlement towards alimony and for child. So on divorce petition below are the points I am writing - - XYZ money for the wife and the child - leaving my portion of the flat and making wife as the sole owner. Hence , wife cannot claim any further for " herself " and /or on behalf of the child and wife is relinquishing and waving off all her rights for any future claim for herself and / or on behalf of the child. Based on these above two points as suggested by my lawyer I want to know from experts here - 1. Based on mentioned above points , I can clearly understand that my wife cannot claim further after divorce either for herself or on behalf of my daughter..........But, I want to know can my daughter who is 5 years old now claim separately for child maintenance again when she will grow up say 15 years old or later on till she is not married ? 2. Incase daughter asks later on for giving her child maintenance , can I show her the divorce paper to tell her that during divorce I did give money and my portion of the flat both for her mom's alimony and for her as well? Or will I be still liable to pay a separate money to my daughter if my daughter asks separately ? 3. When my daughter is 5 years old now , can anyone else from my wife's family ask for child maintenance on behalf of my daughter because my wife cannot claim as I am writting on paper that wife is relinquishing and waving off her rights to ask for further claim ? 4. After divorce, I might marry someone and I don't want to spend a single penny on my previous marriage as I am giving enough during divorce already. So all these above information I gave you in details because I want to know """""Can my daughter still come to me and claim again from my future property , future savings or my salary when in divorce petition it is written clearly that the cash I am giving for the wife and the child and flat I am making wife the sole owner and hence wife cannot ask or claim further for herself or on behalf of the child ?""""""" Incase daughter still claims maintenance , what should I do as I want to save all my future property , my savings , money for my second wife and children from second marriage ?
