42 squatters in Diego Martin were given Certificates of Comfort by the Government last Friday.
However, they have been advised that the document was not a Deed and should not be sold, assigned or transferred to anyone else.
Housing Minister Edmund Dillon says it was also not a license to grab more land by extending the boundaries.
Following the CoC, the holders will be issued a Statutory Lease, giving them a maximum of 30 years to pay for the land, which will be sold at a quarter of its value.
When the land is paid for, the beneficiaries will be eligible for Deeds of Lease for a period of 199 years.
