My husband got a divorce with his ex wife the proper way with witness and everything 8 months after his divorce we married met through our families everything was done the proper way with everyone knowing he was divorced previously. 10 months down the line he finds out she has had his child when she told him she had miscarried the child, she was pregnant all along but my husband didn’t know. Is his divorce valid? And is my nikkah with him valid?
