Will ex-husband's dishonesty affect children?

No, if parents are included in the list of untrustworthy people, it will generally not affect children. There are only restrictions on faithless people, but no provisions for their children.

Legal basis:

Article 6 of the "Several Provisions of the Supreme People's Court Municipality on Publishing the List Information of Dishonest Executed Persons" shall be notified by the people's court to the relevant government departments, financial regulatory agencies, financial institutions, institutions undertaking administrative functions and trade associations, so that the relevant units can impose credit punishment on dishonest executors in terms of government procurement, bidding, administrative examination and approval, government support, financing and credit, market access and qualification identification in accordance with laws, regulations and relevant provisions.
