Sister selling her share of the estate to her sibling

Q: A person passed away, and among the heirs are two daughters, one of which is rich and the other is poor. The rich daughter does not want to take her share of the inheritance and wants to give it to the poor daughter. 

However, she was told that this is not permissible without her first taking possession of her share. My question is, how will she take possession of her share independently if the share consists of properties that are jointly owned with other relatives, as well as the business which is also in partnership with others? 

In such a case, where independently taking out one's share will be difficult and tedious, can she merely hand over her share to her sister without first taking possession of it? If not, what are her options?

Making an effort to repay the debt of one's deceased brother

Q: My brother passed away a few years ago. I knew he had a debt when he was abroad. But I don't know the whereabouts. What can we do for that? 

It's not really possible for us to re-pay his debt as we are not a wealthy family. What can we do for my brother to save him from the hell fire? Sometimes my brother comes in my dream suffering from pain or as tortured telling me to save him. What can I do for him?

Using a continuous glucose monitor

Q: I am, as per blood results and my doctor, on the brink of Type 2 diabetes. One of the options to try and reverse this is to use a continuous glucose monitor. What is the position with this in terms of ghusl? 

The patch is kept on for 14 days at a time and then changed. Please advise what is the position in terms of ghusl as if we are required to remove this in ghusl then it cannot work as each patch costs almost R1500 per 2 weeks.
