Art. 125Security for the claims against the private claimant
1 A private claimant, with the exception of the victim, must on application by the accused lodge security in respect of the accused's probable costs arising from the civil claim if:
a.
he or she is not domiciled or has no registered office in Switzerland;
b.
he or she appears to be insolvent, in particular if bankruptcy proceedings have been opened or composition proceedings are ongoing or if certificates of loss have been issued;
c.
for other reasons, there is reason to fear that the accused's claim could be seriously jeopardised or frustrated.
2 The director of proceedings for the court shall issue a final judgment on the application. He or she shall determine the amount of security and fix a time limit for its payment.
3 The security may be paid in cash or take the form of a guarantee from a bank permanently established in Switzerland.
4 It may be retrospectively increased, reduced or revoked.
