UN Security Council members have been given a copy of a draft resolution to allow Liberian ex-President Charles Taylor's trial to move to The Hague.
Mr Taylor was captured as he tried to flee Nigeria
Mr Taylor, a former warlord, has been charged with war crimes by the special court for Sierra Leone and is currently in custody in the capital, Freetown.
The UK says he threatens regional peace, backing a move to The Hague.
Meanwhile, Mr Taylor's son Charles Taylor Jr has been arrested in Miami accused of immigration offences.
Mr Taylor Jr, who is a US citizen who has been living in the Caribbean, served as the head of his father's presidential guard, known as the Anti-Terrorist Unit.
The United Nations Security Council ordered his assets to be frozen two years ago.
His father was arrested in Nigeria earlier this week.
The former Liberian president, who faces charges of war crimes and crimes against humanity, is due to make his first appearance before the special court for Sierra Leone on Monday.
But his actual trial will take place on another continent. Shortly after Mr Taylor was captured, the special court asked for his trial to be moved to The Hague because of security concerns.
The government of the Netherlands agreed on condition the Security Council passed a resolution providing the legal basis for such a move.
The draft resolution drawn up by the United Kingdom calls on the government of the Netherlands to allow Mr Taylor's detention and trial to take place in The Hague and to allow witnesses to appear there.
It asks for all states to cooperate and for the secretary-general to assist in the arrangements for the trial, which will still be carried out by the special court.
Charles Taylor had been given asylum in Nigeria under an agreement to end Liberia's civil war, but disappeared from his home on Monday night and was later captured.
He is charged with backing rebels in neighbouring Sierra Leone who were notorious for their brutal attacks on civilians. The Security Council is expected to pass the resolution early next week.
