there are many reasons to deny maintenance to wife
if you catch her in adultry
if she desert you without reason
she is educated and working
if you prove her cruelty on you and many more ; you can check all the judgements in http://mynation.net/docs/ section just search for word “maitenance”
do not try to grab whole hand, try to hold finger 1st. its difficult to get custody of a child if he /she is below 5 years nor court take your appeal if child is less than 5 years old.
but you can ask visitation
once you get visitation then you can ask outing at weekends
then solwly you can ask court to allow child to stay in hoildays/summer time
then its upto child with who he/she has to stay, coz all these will take decades.
