What Is the Register of Members (ROM)?

The Register of Members (ROM) is the official company record listing all shareholders, the shares they hold and the dates they became members.

Register of Members (ROM) Meaning

The register of members centres on transparency and legal proof of ownership. To define Register of Members in practice, it contains each shareholder’s name, address, share class, number of shares and the date of allotment or transfer. A clear Register of Members definition matters because, in UK company law, the ROM, not share certificates, is the final authority on who legally owns shares. Companies must maintain it accurately, update it after every share issue or transfer and keep it available for inspection. The ROM stands for the core document that underpins shareholder rights, voting powers and dividend entitlement.
