Her father refused to marry her to someone so the judge did the marriage for her
Question

                My father is Muslim.  He has wrong thoughts about Islam, such as his situation of hejab and mixing. He says: “will a person be judged if good or bad by his religiousness?”  He says also that none can implement all the commands of Allah, even the prophet (PBUH) himself could not, meaning the issue of polygamy. My sister has rejected Islam and became Christian, and my father did not object to this, he even sees her as better than me. My mother is Christian as well. 

A noble but disabled man has proposed to me and I accepted him. But my father refused him because he is disabled and from a simpler standard of living than ours. We are rich family. 

After I completed my study at university, my family planned to cut my relationship with the good friends of mine, they planned to change my life gradually. So I left home and planned for marriage. Two months later I got married to the Muslim man in a shar’ee court. 

The question: is my marriage islamically valid? What should my situation towards my family be? Shall I continue boycotting the relationship with them?.
Praise be to Allah.
    Firstly: 
We 
    praise Allaah for having enabled you to adhere to the path of guidance and 
    righteousness and we ask Him, may He be glorified and exalted, to grant you 
    more of His bounty. 

    Secondly: 

    The woman should endeavour to marry one who is religiously committed and of 
    good character, who can protect her and take care of her, and enable and 
    help her to practise her religion, as well as help her to raise righteous 
    children in accordance with the principles and morals of Islam. 

    The Prophet  (peace and blessings of Allaah be upon him) said: “If there 
    comes to you one whose religious commitment and attitude pleases you, then 
    marry [your female relative who is under your care] to him, for if you do 
    not do that, there will be tribulation on earth and much corruption.” 
    Narrated by al-Tirmidhi (1084) from Au Hurayrah; classed as hasan by 
    al-Albaani in Saheeh al-Tirmidhi. 

    Thirdly: 

    Marriage is not valid except with a wali (guardian), and a woman has no 
    right to marry herself, because the Prophet  (peace and blessings of 
    Allaah be upon him) said: “There is no marriage without a wali.” Narrated by 
    Abu Dawood (2085), al-Tirmidhi (1101) and Ibn Maajah (1881) from Abu Moosa 
    al-Ash’ari; classed as saheeh by al-Albaani in Saheeh al-Tirmidhi.

     And he  (peace and blessings of Allaah be upon him) said: “Any woman 
    who gets married without the permission of her wali, her marriage is 
    invalid, her marriage is invalid, her marriage is invalid… and if there is 
    any dispute, then the ruler is the wali of the one who has no wali.” 
    Narrated by Ahmad (24417), Abu Dawood (2083) and al-Tirmidhi (1102); classed 
    as saheeh by al-Albaani in Saheeh al-Jaami’ no. 2709. 

    But if the wali refuses to marry the female relative under his care to a 
    compatible man with whom she is pleased, then he is preventing her from 
    getting married and guardianship passes from him to the next closest male 
    relative on the father’s side. 

    Ibn Qudaamah (may Allaah have mercy on him) said: What is meant by 
    preventing her marriage is preventing her from marrying a compatible man if 
    she asks for that and each of them wants to marry the other… 

    And whether she asked to get married for a mahr (dowry) like that of her 
    peers or less. This is the view of al-Shaafa’i, Abu Yoosuf and Muhammad. 
If 
    she wants to marry a specific compatible man, and he wants her to marry some 
    other compatible man, and refuses to marry her to the one whom she wants, 
    then he is preventing her marriage. 

    But if she asks to marry someone who is not compatible, then he has the 
    right to refuse that and he is not regarded as preventing her marriage. End 
    quote from al-Mughni (9/383). 

    Because guardians usually prevent marriage in such cases, there is nothing 
    wrong with the woman referring the matter to the shar’i judge, who may then 
    ask the guardians to do her marriage. If they refuse then he may do her 
    marriage himself. The Prophet  (peace and blessings of Allaah be upon 
    him) said, as in the hadeeth quoted above: “and if there is any dispute, 
    then the ruler is the wali of the one who has no wali.” 
     

    Based on this, your marriage contract is valid and it is not permissible to 
    annull it, because the shar’i judge became your wali after your father 
    refused to arrange your marriage. 

    Fourthly: 

    You have to honour your parents and treat them kindly, and uphold ties of 
    kinship with them even if it is only by speaking to them on the phone, until 
    they calm down and you are able to  visit them, for parents’ rights are 
    great. Hence the duty to honour them is mentioned repeatedly in the Qur’aan, 
    as Allaah says (interpretation of the meaning): 

    “And We have enjoined on man to be good and dutiful to his 
    parents; but if they strive to make you join with Me (in worship) anything 
    (as a partner) of which you have no knowledge, then obey them not. Unto Me 
    is your return and I shall tell you what you used to do”

    [al-‘Ankaboot 29:8] 

    “And We have enjoined on man (to be dutiful and good) to his 
    parents. His mother bore him in weakness and hardship upon weakness and 
    hardship, and his weaning is in two years __ give thanks to Me and to your 
    parents. Unto Me is the final destination.

    15. But if they (both) strive with you to make you join in 
    worship with Me others that of which you have no knowledge, then obey them 
    not; but behave with them in the world kindly, and follow the path of him 
    who turns to Me in repentance and in obedience. Then to Me will be your 
    return, and I shall tell you what you used to do”

    [Luqmaan 31:14, 15]

    You have no right to cut them off, rather you must strive to calm them down 
    and put their minds at rest, and soften their hearts with money and gifts to 
    earn their love, and ask Allaah to guide your family. 

    May Allaah help us and you to do that which He loves and which pleases Him. 

    And Allaah knows best.
