The future ownership of Hearts has been thrown into doubt after a court in Lithuania froze the assets of the SPL club.
At the hearing in Kaunus, assets controlled by Russian-born businessman Vladimir Romanov, and his UBIG investment vehicle which controls Hearts, were seized.
A number of companies are suing Romanov, and his sister Olga Goncaruk, in an effort to recover 'large debts' jointly undertaken by the pair.
In a statement, court spokeswoman Gintare Putnikiene said: "Any sale or transfer of UBIG's shares in Hearts or its other property is forbidden."
The move comes two months after Lithuania's central bank suspended operations at Ukio Bankas, majority-owned by Romanov, citing irregularities.
Foundation of Hearts, a supporters group based in Edinburgh, earlier this month claimed it was 'in negotiations with other fan associations to buy a majority of Hearts shares from UBIG'.
Hearts refused to make any comments on the latest developments concerning Romanov, who bought the struggling club in 2005.
