Is the money a contractor pays an engineer to register his name permissible or impermissible?

The legal requirement for a contractor to have an engineer is correct and beneficial, as it protects people's rights and properties. Merely registering a name without direct involvement and supervision from the engineer is considered devouring wealth unjustly, which is forbidden in Islamic law. Profit is only deserved through capital, work, or guarantee. Taking money without these reasons is deception and a violation of the ruler's command.
