A carer unlawfully obtained €18,000 in unemployment payments while working, Dublin District Court has heard.
Louise Daly (31), of Nephin Road in Cabra, was ordered by Judge John Brennan to appear again for sentencing in June.
She was prosecuted by the Department of Social Protection.
Prosecution solicitor Joseph Maguire said Daly, who pleaded guilty, faced six counts of making false declarations in claiming Jobseeker's Allowance while working between July 2010 and December 2014.
She had no previous convictions and €18 is now being deducted weekly from her one-parent family payment.
She has also made a lump sum repayment but €14,283 remains outstanding.
In the district court the offence can result in a fine of up to €2,500 and a possible six-month sentence, in addition to having to repay the social welfare authorities.
The court can only consider leaving defendants accused of dole fraud without a criminal record if the money has been repaid.
Judge Brennan said the period of time involved in paying back the money was an aggravating factor.
Granting an adjournment, he warned that, unless a credible payment plan was proposed, a custodial sentence would be considered.
