السلام عليكم I’ve heard that seeing a woman in her normal clothing and unveiled at a marriage meeting is permissible if acceptance from the family is highly likely. In that case. Is it correct to have a video call and see her in that state after only speaking with the family in a group chat?

Ustadh AbdulAziz al-Haqqan
I always advise that you go in person rather than using video calls or similar methods. Go in person; it makes a huge difference.
