James Ibori, a former governor of Delta State who was convicted in a British court in 2012, is at risk of receiving a further 10-year prison term over money he is due to pay.
Channels Television reported that the court is planning to seize more than £100 million ($129 million) from the ex-governor.
Ibori did time in prison for charges of money laundering and fraud, and he only recently returned to Nigeria.
The former governor was indicted by British authorities for allegedly taking public money and launder it through UK banks and real estate. But in February of 2017, the trial for the confiscation procedures against Ibori began.
Southwark Crown Court Judge David Tomlinson has made findings of fact on the sum of money associated with Ibori.
On Thursday, the prosecution and the defense presented their views to the judge about how the confiscation amount should be determined in light of the evidence produced so far.
Ibori did not show up to the hearing since he had already returned to Nigeria after completing half his sentence.
In court, Jonathan Kinnear, the prosecutor, stated that £101.5 million was the total amount that should be seized from Ibori.
Kinnear requested an additional five to ten years in prison if he is unable to make restitution.
On Friday or shortly thereafter, the judge will likely issue a ruling.
