As a lawyer, I cannot provide specific information about a particular project or endorse any product. However, I can provide general information about the legal regulations and procedures related to the marketing and sale of properties in Egypt, including The East Tower by UC Development in New Capital.

The Egyptian Real Estate Law No. 148 of 2001 establishes the legal standards and procedures that regulate the buying and selling of properties in Egypt. Real estate developers must obtain a license from the Ministry of Housing, Utilities, and Urban Communities before commencing any residential or commercial project.

The license serves as proof that the project meets all legal requirements related to building codes, environmental regulations, and the availability of essential infrastructure such as water and electricity. Additionally, the developer must disclose all pertinent property details, including specifications, location, and size.

Moreover, the developer must establish a real estate development fund to finance the project. In turn, the independent board manages and monitors expenditures to ensure efficient use of the funds allocated to a specific project.

It is worth mentioning that any written contract between the developer and the buyer must be registered with the Real Estate Registry. The requirement ensures that the buyer's rights are protected, and property ownership is legally transferred to the buyer.

As a lawyer, I recommend that any interested buyer should undertake appropriate research and due diligence before investing in any property. This will include verifying the license, reviewing contract clauses, examining developer track records, and seeking professional advice when required.

In conclusion, the Egyptian Real Estate Law provides a standard legal framework that ensures the buyer's and developer's rights and responsibilities are respected. Any project, including The East Tower by UC Development in New Capital, would adhere to those regulations, providing a secure and legitimate investment opportunity.
