The court may, on its own motion, order the attachment of the obligor's income where the court has a reasonable basis to believe the obligor will not comply with the order of support. In making this determination, the court may consider evidence of the person's previous violations of orders entered in any jurisdiction or evidence that the obligor has attempted to conceal income or to transfer, convey or encumber property in order to reduce the obligor's support obligation. Attachment shall occur under this subsection without amendment to the order of support and, if arrearages occur, without the need for a judicial or administrative hearing.
