There are general requirements that are usually needed for school admissions in the UAE, especially if the parents are divorced. The specifics can vary depending on the school and the emirate, but commonly required documents may include:

1. 
   Passport Copies: Both of the child and the parent or guardian.
2. 
   Visa Copies: Again, for both child and parent or guardian. Usually, the parent or guardian needs to have a residence visa.
3. 
   Birth Certificate: An attested copy of the child's birth certificate, usually translated into Arabic.
4. 
   Immunization Records: Some schools may require immunization or vaccination records.
5. 
   Previous School Records: Academic records, transfer certificate, etc., from the child’s previous school, often required to be attested.
6. 
   ID Photos: Passport-sized photos of the child.

   Divorce Decree: In cases where the parents are divorced, an attested copy of the divorce certificate (the Khula document in this case) may be required. The document may also need to be translated into Arabic and notarized depending on the emirate and the school's policies.
8. 
   Parent’s Emirates ID: Some schools might require a copy of the parent’s Emirates ID card.

Given that the divorce was finalized via Islamic Khucess, the Khula documents from the Telangana Wakf board and the Qazi office would generally serve as the divorce decree. These documents may need to be attested by the Indian authorities and then by the UAE embassy in India. They may also require translation into Arabic.

Since regulations can vary and are subject to change, it's important to consult directly with the school to which you're considering applying.
