The ruling on the marriage of a woman whose family was informed of her husband's death

Question:
Another man says: I am a married man with two sons. After that, I traveled to a country other than my own, and my family received news that I had died. After that, my brother married my wife. At that time, I was a prisoner. Later, it became clear to them that I was alive and a prisoner. So what is the validity of this marriage? And who has the stronger right to her?

Answer:
Contact the court. Write to your family that you are alive so that the last husband separates from her. After that, contact the court, and the court will clarify to you what is obligatory for you and your brother, for you and for your brother.
