Is it permissible for an employee to receive payment for documenting the status of a plot of land or for placing it under reservation on behalf of the service provider?

If the work of the representative and the correspondent involves inspecting the land and submitting reports to the judge, and they receive a salary from the state, then it is not permissible for them to take a fee from the plaintiff. Otherwise, it would be consuming wealth unlawfully, as stated in the Almighty's saying: "And do not consume your properties among yourselves through falsehood." However, if their work does not obligate them to go to the land site, and they only go out at the request of the plaintiff and at his expense, then there is no objection to them taking a known fee determined by the judge and agreed upon by both parties.
