Various masaail of Nikaah

Q: I want to ask about nikah. I live in Dubai and my fiancée came from UK with her father to get married to me. Before marriage, a medical test is mandatory here. We did the medical test and the doctor told us that we both carriers of thalisemia, so the court rejected our medical report and refused to get us married. We got married out of court with two witnesses and the girl's father. We both love each other and we got married. Now we planning to go to Pakistan to register our nikah there so we can have a legal marriage. Please guide us if this is permissible.
