Q: Wife asked her husband a question. The question is: Who writes divorced in marital status on visa forms? Husband said: Maye someone was divorced and wants to visit abroad then he will write divorced as his marital status. The husband had no bad intention. He just said that to explain to his wife. The wife is worried that divorce took place.

Q: I had a nikkah before 8 months and before nikkah we agreed about haq mahr which was 300000 pk RS but during writing the nikkah, the father of the girl changed his mind without even informing me and asked to write 4000$ insteed of 300000 pk RS.

Also, he added a condition that if I give talak (breaking of nikkah ) before marriage, I have to pay 6000$ if I give talak after marriage, I have to pay 15000$. I was shocked and tried to ask why all this changed. The witness told me that it's ok because I'm not going to give talak. It's just a formality, so I accepted out of respect because they will be my family.

Later on we agreed about the day of marriage and they asked for the remaining money. I sent it to them and the remaining 100000, I told them that I will pay it later. They said ok and we agreed about the shaadi date.

All of a sudden the girl and her dad changed their mind again and asked for more money and the girl said she wants to continue studying and I have to wait if I love her.

At this moment I called for help and for a separation and I wanted to break this relationship. What will the consequences be and what do I have to do now? Will they deserve the have of haq mahr as mentioned in Quran or they have to return all my money and what about the condition of 6000$?
