Need Advice on a Rental Dispute

A friend of mine recently moved out of an apartment in Dubai and is having an issue with the landlord over the security deposit and some repair charges. They tried to sort everything out through messages, but neither side seems willing to agree on the final amount. Before taking any formal steps, they want to understand their options and make sure they have the right documents. We’ve been looking into a rental dispute lawyer dubai, but I’d rather hear from people who have dealt with similar situations. Has anyone had a good or difficult experience with a rental dispute in Dubai?
