Serious question: If a business is incorporated with say two or more partners, how can the government interfere with that business account at all, even if an owner owes child support?

These are business accounts, not personal accounts. I can understand Sole P and maybe one owner LLCs or something, but what about major companies that have multiple partners and owners, how can they pop in and do that? Seems like the business would be able to protect that sort of thing from happening no?
