Convicted drug dealer John Gilligan and his family have been given three months by the Supreme Court to leave their homes, before the Criminal Assets Bureau sells them or leases them.
Geraldine Gilligan and her daughter, Tracey, a mother-of-two, had asked to be allowed to stay a further two years in a "cottage" at Jessbrook in Co Meath.
John Gilligan and his son, Darren, sought a two-year stay in relation to a house at Corduff in Blanchardstown, owned by Darren.
Their lawyers told the court that their clients needed time to pursue social housing applications and have their names put on the housing list.
The court was told 41-year-old Darren Gilligan was on disability benefit, while Tracey was a lone parent with two children, one of whom is at primary school.
The court was told there was no evidence of any criminality on Tracey's part and the High Court had found a 20% interest of hers in a property in Lucan, did not represent the proceeds of crime.
Lawyers for John and Geraldine Gilligan indicated they were considering a possible appeal to the European Court of Human Rights.
The court was told that 64-year-old Gilligan was not yet entitled to the State old age pension and may soon have no house to live in.
Lawyers for CAB opposed any lengthy stay.
Senior Counsel Benedict Ó Floinn said the litigation was "prosecuted to a maximum", had gone on for a very long time and had ultimately been found to be unjustifiable.
He said he was not trying to be hard-hearted, but the Gilligans had had a very long time to make alternative housing arrangements compared to many other citizens who faced losing their homes, and there was no reason why they should be in a different position to others now.
The five-judge court said it would grant a three-month stay on its orders allowing CAB to take possession of the two houses.
It also ruled CAB was entitled to the costs of the appeals before the Supreme Court against John, Geraldine and Darren Gilligan.
All four Gilligans got legal aid for the appeals.
The orders made by the Supreme Court represent the end of the Gilligans' 21-year legal battle in the Irish courts over the properties.
