All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
If your mother's family has urged you to falsely claim that you do not know where your father, brother and family members were, then they were very wrong, and you should not have obeyed them about this, especially that the matter is related to marriage.
The most important condition for the marriage contract to be valid is the presence of the guardian, so the marriage contract is not valid without his presence and consent, according to the preponderant view of the scholars, and this is the view of the majority of the scholars Fiqh, contrarily to the view of Abu Haneefah.
For more benefit on the conditions of the marriage contract, please refer to Fatwa 83629.
It is more appropriate for your father to conduct your marriage contract.
If the case is as you mentioned in the question, that your marriage was conducted without his consent, then it is a void marriage.
So you have to separate from your husband either by divorce or by the annulment of the marriage.
If there are any children from this marriage, then they should be traced back to their father as he married you while believing that the marriage contract was valid.
Now, if you wish to renew the marriage contract, then you must conclude it while fulfilling the conditions of a correct marriage mentioned in the above Fatwa.
Your marriage is not valid and there is no consideration of the ruling of the judge with the claim that your guardian was absent (or his whereabouts were unknown) while it is not the case.
Asnal-Mataalib authored by Zakariyah al-Ansaari from the Shaafi'i School reads:
“If she was married off in the absence of her guardian, whereas he is close to the country at the time of the contract, even with his claim that he is near...then her marriage contract is not concluded because the marriage by the judge is not valid with the presence of the personal guardian.”
Allah knows best.
