Marriage Process UAE Issue

Wondering if anyone else has gone through what I am going through

Im hoping to get married in about 2 months, were both muslim, im an indian passport holder my fiance has a US passport
According to UAE Sharia court law, her father must be present or give consent to someone else to allow the marriage to happen, unfortunately her father left the family over 10 years ago and she has no idea where or how to even contact him......
Her mother and 2 adult brothers are all available to "give consent"
The officiates that I call all say its not possible to get married basically because theres no father or she needs a US Govt issued "Lack of father" document which doesnt exist

So how on earth am i supposed to get married or bypass this ridiculous stupid requirement
or if anyone has any contacts for a lawyer who deals with these sorts of cases, it would be much appreciated
