How much time does a case of medical malpractice take if all reports are ready?

Hello, Good Day,

My wife went through nose surgery a few years ago in a reputed hospital in Dubai. We were not satisfied with the surgery and we filed a complaint with Dubai Health Authority.

After initial investigations, they found there is a medical error and issued a report to us. However, the doctor went in appeal to The Higher Committee For Medical Liability in MOH.

And now, this committee came up with a final decision stating "Doctor did not comply with the accepted medical procedure and to this medical error, the patient is suffering and have to go for another surgery"

As we have both final reports one from DHA and the other from MOH, we are ready to file a lawsuit. But prior to that, we need to know the estimated timeframe and cost associated with the lawsuit.

Thank you

F. S.
