While some thought the mother was being reasonable, others believed that if she was putting on the party Ms Ali should pay the whole cost.
Ms Ali explained that she invited all of her sons' 60 school friends to come along as they were in different classes, and didn't want any child to miss out.
She argued that she had spent more than her fair share paying for her children to attend their friends' parties, and that the bill for the party she was throwing would still reach around £500 (NZD $966) even with subsidies.
One parent was left less than impressed and called Ms Ali out in a Facebook post: "In all my years of hosting and being invited to kids parties, I have never been asked to pay for attending a party. Is this the done thing nowadays?"
However, Ms Ali, who is in her second year at De Montfort University, told presenters Eamonn Holmes and Ruth Langsford, that the cost of the ticket was in lieu of a gift because her children have special needs.
Speaking on the show she said "The parents said if you don't want presents let us pay. I didn't want them to contribute but they said let us pay half.
"It costs more to buy the presents, I've said don't do that because they are special needs. I didn't want anyone to feel left out."
It costs £11-per-child to come along to Fun Valley, in Evington, Leicester, so if all of the boys' friends go to the party it could cost £660 (NZD $1,276), before Ms Ali has paid for goody bags and cake.
During the heated debate on This Morning, Ms Ali was joined by journalist Liat Hughes Joshi who blasted the request as "rude".
She fumed: "It is massively excessive… You don't have to invite the whole class."
Those watching the debate were divided with some agreeing with the single mother's money-saving hack.
One said: "I actually think it's a great idea to get the parents to contribute! I would more than happily pay. It's lovely to invite the whole class when they are little but it's so expensive."

Another added: "I have 3 children and it would actually save money not to buy a present and to just pay for my child to go to the party! Don't see a problem at all."

But those unimpressed with the charge said: "Sorry height of rudeness to ask parents to in pay to go to your kids party."
"If you have a party for your child, you pay for it. End of. This woman making a mountain out of a molehill, if you can afford it why not pay," one fumed.
The former council worker said only one parent had complained and others had taken to Facebook in support of the mother.
