Nikaah & Marriage Issues

Divorced couple keeping each other informed via sms regarding the needs of their child

Q: Husband has issued one talaaq and wife is observing iddat. What is the ruling regarding informing each other about the child getting sick, needing to be taken to the doctor, etc. as these are matters that will be ongoing for life? Completely understood that they become complete strangers and no communication allowed, is it allowed to send an sms to prove the money was deposited into account, the child needed to go for tests, etc. to keep the parents informed about the child.

Husband not paying mahr

Q: It will be 1 year in May since I done my nikah. During this time my husband still has not given me my Mahr. We both live in different city's but he travels every weekend to spend some time with me. During this whole time he has not provided anything for me e.He has never bought me anything since we have been married and I have bought him endless things and also borrowed him money which I have asked back for. He still hasn't given it back. He owns his own business so he is not short of money. It really upsets me that it's going to be almost 1 year and he still hasn't given me my mahr. Please advice me on what I should do?
