Advice urgently wanted re divorce

I have been married to an Egyptian for over twenty years and have two children, both under 18 years of age. We lived in Egypt for a number of years but have since returned to the UK. Two months ago he left our rented home in the UK and returned to Egypt. He took all of my papers (Egyptian ID, driving licence and contracts) and used an old power of attorney to transfer our property and business in Egypt out of our joint names into his own. He also  transferred all of our money into his own account, leaving me with no access to our money. He refuses to support the family here and has completely cut off all contact with us. What are my legal rights? Can anyone recommend a lawyer in Egypt who can help?
