The Holiday Meal Payments Bill is set to face a decisive vote in the Northern Ireland Assembly on Tuesday.
Sinn Féin's Danny Baker introduced the measure after his party noted that Northern Ireland remains the only UK region lacking government-funded holiday food support.
This gap emerged when the Department of Education concluded its £27-per-fortnight holiday meal grant in 2023.
Campaigners and parents have expressed welcome towards the proposal, with Louise McCullough from east Belfast among those who spoke at a recent event supporting the initiative.
The legislation would establish a new payment mechanism for households where children qualify for free school meals based on an annual income threshold of £15,390.
Payments are designed to be distributed outside of term time to assist with food costs during school holidays.
Although the bill has been scrutinised by members of the legislative assembly over the past nine months since its March introduction, significant amendments were rejected last month.
Democratic Unionist Party Education Minister Paul Givan has warned that implementing the law would cost his department between £25m and £30m annually.
Givan's party is expected to vote against the measure on Tuesday, but Sinn Féin anticipates securing passage through backing from Alliance and SDLP MLAs.
