Document classification

Why are there different access levels?

Transparency requires the rules, criteria and principles governing APMLS to be clear and accessible. It equally requires the Association to protect personal data, disciplinary proceedings, commercially sensitive information, technological security and documentation whose disclosure could harm its members or the running of the organisation.

For that reason, APMLS documentation is classified according to its nature and purpose.

Public

Public information

Rules, ethics, governance, accreditation criteria and principles of participation.

Members

Member information

Manuals, tools, training and the operational documentation needed to use APMLS services.

Restricted

Restricted information

Disciplinary proceedings, legal opinions, security, investigations, contracts and other legally or operationally protected information.

Categories of restricted information

Restricted

Disciplinary proceedings and investigations Complaints and reports Legal opinions Security and cybersecurity documentation Internal audits Supplier contracts Commercially sensitive information Committee minutes subject to confidentiality

These categories exist and are managed by the competent APMLS bodies. They are not published individually because they contain personal data, live proceedings, commercially sensitive information or security matter. The rules and procedures governing them are public.

Competition

Competition and commercial independence

APMLS promotes professional cooperation without interfering in its Members' commercial autonomy. Each company and professional independently determines its prices, fees, commissions, commercial strategies and market decisions.

Market information provided by APMLS must respect principles of aggregation, confidentiality and protection of commercially sensitive information.

Read the Competition and Compliance Policy

An independent non-profit association. We set the rules of real-estate cooperation in Portugal and publicly verify who follows them.
