Praise be to Allaah.

Firstly: 

If a man is forced to issue a divorce by means of physical harm or damage to his property, or threats to do such things to him or he is threatened with imprisonment, by a person with power who he thinks most likely will carry out his threat, the divorce does not count as such in that case. 

It says in Zaad al-Mustaqni‘: Whoever is forced to do something unjustly by means of harm caused to him or to his child, or by having property taken away from him, or by means of threats to do one of these things by a person with power who he thinks can carry out the threat, and he issues a divorce on that basis, it does not count as a divorce.

Ibn al-Qayyim (may Allah have mercy on him) said: The Sahaabah ruled that the divorce issued by one who is forced to do it does not count as such. It was narrated from ‘Umar that a man suspected a rope so that he could collect honey from the mountain; his wife came to him and said: I shall certainly cut the rope if you do not divorce me. He adjured her by Allah not to do that, but she insisted, so he divorced her. He came to ‘Umar and told him what had happened, and he said to him: Go back to your wife, for this is not a divorce. The opinion that it does not count as a divorce was also narrated from ‘Ali, Ibn ‘Umar and Ibn al-Zubayr (may Allah be pleased with them).

End quote from Zaad al-Ma‘aad, 5/208 

And he (may Allah have mercy on him) said: He [i.e., Imam Ahmad] said according to the report of Abu’l-Haarith: If one who is forced issues a divorce, the divorce is not binding. If something similar is done to him as was done to Thaabit ibn al-Ahnaf, then he has been forced, because they squeezed Thaabit’s leg until he issued a divorce. Then he went to Ibn ‘Umar and Ibn al-Zubayr, who did not think it counted for anything. And Allah, may He be exalted, says (interpretation of the meaning): “except him who is forced thereto and whose heart is at rest with Faith” [al-Nahl 16:106]. This verse was quoted as evidence by Imam al-Shaafa‘i (may Allah have mercy on him) to prove that divorce issued by one who is forced does not count as such. 

In Sunan Ibn Maajah it is narrated from Ibn ‘Abbaas (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said: “Allah has let my ummah off for mistakes, forgetfulness and what they are forced to do.

End quote from I‘laam al-Muwaqqi‘een, 4/51. 

Based on that, your divorce does not count as such and your wife is still married to you. 

You have to refer your case to the shar‘i court to cancel the divorce and take back your property. 

Secondly: 

The threefold talaaq counts as one talaaq according to the correct scholarly view. So whoever divorces his wife with a threefold talaaq – willingly – it counts as one talaaq and it is permissible for him to take her back during the ‘iddah. 

Thirdly: 

If the wife knows that her husband’s talaaq was issued under duress, it is not permissible for her to marry another husband, because she is still married to the first one; her second marriage is invalid and it is zina (adultery). 

And Allah knows best.
