You can't get a legal opinion in the UAE. I mean, you can get an opinion, but it's just that, an opinion. It's just something some expensive lawyer pulls out of their a*s.
It has no relevance for anything. The lawyer won't be liable. The state won't care about the lawyer's opinion. A complete waste of money.
And even from the state you won't be able to get a ruling, unless it's too late and your already on trial.
For me that's the biggest negative with the UAE. Then again, people are "usually fine". You have to know that if you want to live in︀ the UAE, you have to accept this risk.
