Hello, I would like to ask a question about property inheritance in Lebanon.
In case of a death of a mother, who would inherit her properties? Let it be known that the estates are under her maiden name and that the other parent is also deceased. Thank you for your answer.

Hello.
I would like to change my surname. The issue is that when we left country many years ago my parents registered us under a different name in the destination country. Have been using that name all my life. I have a Lebanese passport under my original name and a euopean passport with the name that I have always used. Now I would like to change the original name to the one I have always used. Is it doable and what do I have to do. Is there lawyers that have done this in the past that can be recommended?
Thanks in advance.
