I have a virgin friend who is interested in doing mu’tah but it will be very hard for her to get her father’s permission.

She hasn’t asked yet but she knows her father will not agree to it.

The couple wish to practice Mutah to refrain from having any sort of haram in their relationship, and because they are both very serious about wanting to get married in the future In Sha Allah.

Is there any chance that the sister will be able to do mutah even without the permission?

Permission from father is necessary.
