The new personal insolvency guidelines say people who enter arrangements should not expect to live in luxury or at a subsistence level.
Details of the scheme - under which there will be three options depending on the amount of debt involved - are being published this afternoon.
There will be a number of strict conditions for people who avail of the service - depending on a household's composition and access to public transport.
Individuals will be given a budget of €247 per month for food, €31 for healthcare, €35 for clothing and almost €29 per month for socialising.
According to the guide a reasonable amount of money will be allocated for spending on childcare or mortgage repayments - depending on circumstances.
The Justice Minister Alan Shatter said the Insolvency Service of Ireland will not deprive people from continuing in employment.
"The guidelines on reasonable expenses provide an essential defensive shield to ensure that neither financial institutions nor other creditors attempt to provide debtors of funds they truly need for reasonable household family expenditure, he said.
"Or indeed deprive debtors in employment from benefitting from continuing employment."
