Under Article 17 of the Egyptian Civil Code, inheritance, wills, and all dispositions taking effect after death are governed by the law of the deceased's nationality at the time of death. This means that if you are a foreign national, your home country's inheritance law will generally determine how your estate is distributed — not Egyptian law.
However, there is a crucial practical consideration regarding immovable property in Egypt (land and buildings). Article 18 establishes that real rights over property in Egypt are governed by Egyptian law, which can create a conflict between Article 17 (nationality-based inheritance rules) and Article 18 (location-based property rules). Egyptian courts may apply Egyptian law to the disposition of Egyptian real estate even if you are a foreign national.
Regarding the form of your will (how it must be written and signed to be valid), Article 17 allows greater flexibility — a will is formally valid if it complies with the law of the place where it was made, or the law of your nationality. This means a will properly executed under your home country's rules can still be recognized in Egypt. To avoid complications, consider drafting a separate Egyptian will for any Egyptian assets and having it notarized by an Egyptian notary (Shahr Aqari).
