Entering Makkah without ihraam

Q: I am planning to go for Umrah in Ramadhaan. We will be reaching Jeddah at around 10 pm and after immigration formalities we will travel to Makkah. We will hardly be reaching around Sehri.

The problem is that we will be too tired to perform Umrah immediately. Is it possible that we will not make niyyat of ihraam and after reaching the hotel, we will take rest and then the next day in the evening after Iftar we will go to nearest miqaat place and then make niyyat of ihram and perform Umrah.

Threatening one's wife with divorce without intending divorce

Q: I told my wife "If you ever work in that place again, I guarantee you it will break our relationship"

The intention when saying those words was in order to threaten her so she doesn't work there, but I'm not sure if I had the intention of actually divorcing her immediately if she started working there. It was in the context of that if she works there, it will affect our relationships trust. Thus it may lead to a break up, so she should be careful.

Using one's stepfathers name in the nikaah certificate

Q: I am getting married in July. My mother has done 2 marriages. She is separated and divorced from her first husband long time ago. I was born from her 2nd husband. Not keeping any difference, she and my real biological father kept the name of her first husband as my fathers name.

All my life, my education, identity card everything is made on his name. In my nikaah, my wali agreed to be there but in the nikaah nama (cerficate) the name of my stepfather would come and not my real father. Would my nikaah be valid?
