Is a lawyer's signature on a crime scene damage assessment report considered a sin, knowing that he has no experience in assessing damages, and aims to expedite compensation for the injured citizen?

"The estimation of the arsh (compensation for injury) and the entitlements of the injured party is determined by the Sharia judge or those authorized by him. There is no harm in the injured party agreeing to an assessment made by a neutral governmental committee, as the estimation of damages is referred to specialists. Signing off on what the committee has concluded is not sinful, because this represents the end of the pleading regarding the estimation of damages. The responsibility for any unfair assessment falls upon the competent authority."
