As an lawyer, I would first inquire about the specific issue or concern related to the compound Gharb Arabella in New Cairo, Egypt. Once I have a clear understanding of the situation, I would research applicable laws and regulations related to real estate and property ownership in Egypt.

If there is a dispute or legal issue related to the compound, I would advise my client on the options available to them and guide them through the legal process. This may involve negotiating with other parties, drafting legal documents, or representing my client in court.

It is important to ensure that all legal actions and advice given are in accordance with applicable laws and regulations in Egypt to protect the legal rights of my client.
