Praise be to Allah.
    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. End 
    quote. 

    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 suspended 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.
