Billionaire Farkhad Akhmedov agreed to pay his ex-wife around 135 million pounds ($186 million), ending the largest financial dispute that Britain’s divorce courts have ever seen.

Tatiana Akhmedova accepted a cash and art settlement that is around one-third of a 2016 court award, a spokesman for Akhmedov said in a statement. The agreement brings to a close the bitter and long-running legal fight and means that the oligarch will retain his 115-meter (380-foot), nine-deck luxury superyacht Luna.

A spokesman for Akhmedova didn’t immediately respond to a call and email requesting comment.

Billionaire’s Yacht Holed Up in Fight Over London Divorce Award

The fight for assets has spanned at least nine jurisdictions since a London judge awarded Tatiana some 450 million pounds -- amounting to 41% of Farkhad’s assets -- in 2016. Tatiana has been funded by litigation finance group Burford Capital Ltd., which said it will receive $103 million.

Azerbaijan-born Farkhad made much of his money from the sale of his stake in a Russian gas producer in November 2012 for $1.4 billion. But the billionaire refused to make any divorce payments, calling the 2016 divorce order illegitimate, and moved to Russia.

“I will burn this moneys rather then will give her,” Farkhad said in a WhatsApp message to his son in March that year.

The couple met in 1989, marrying four years later and moving to London, where Tatiana has lived with their two children ever since. The marriage formally ended in late 2014.
