The European Convention on Human Rights will be incorporated into Manx law from 1 November. The change means people living on the Isle of Man will be able to take action in local courts for alleged breaches of their human rights.
It will not prevent anyone taking a case to Strasbourg's European Court.
The island has been covered by the convention since the 1950s, but Chief Minister Donald Gelling said the laws would now be "more accessible."
He said: "The principles embodied in the Human Rights Act are not new, but they will be more accessible to the people of the Island.
"The Council of Ministers believes that bringing the Act into force is an important step in the right direction, reinforcing our system of justice and our international reputation."
The act received Royal Assent in 2001, after which there was an education and training programme to help public bodies prepare for its introduction.
