No more than six months. The Provisions of the Supreme People's Court on the Seal-up, Seizure and Freezing of Property in Civil Execution of People's Courts stipulates that the period for freezing pensions shall not exceed six months. Because the pension belongs to one of the funds of the person subjected to execution, according to the relevant regulations, when the people's court freezes the bank deposits and other funds of the person subjected to execution, the period cannot exceed six months.
