Requirement Of Mehr And Validity Of Marriage
I am sorry I cannot tell you that as it is for God to decide. I can only share with you the requirements as ordained by Him. Please also know that God is necessarily forgiving to those who fix their errors upon realizing and make sincere repentance at once.
As explained in the link I shared above, the husband should offer you a dower which is in accordance with the social status of the bride and financial status of the groom. You can mutually decide the amount according to the norms of the society. If the husband gives you the decided amount right away, which is very much preferable, then there is nothing further that needs to be done. However, if that is not possible then either the nikah contract can be legally amended or a separate legal contract can be drawn for the financial obligation of the husband towards you.
