Custody Models for Tokenised Real‑World Assets: Nominee, Trustee and Crypto‑Custodian Explained

Custody is the legal and operational layer that sits between an investor and the underlying real asset. In traditional property funds, nominee or trust arrangements are common: a nominee holds legal title on behalf of beneficial owners, or a trustee holds assets in trust according to a deed of trust. These models rely on established company and trust law, regulated depositaries or trustee oversight, and clear segregation of client assets to protect investors if an intermediary fails.

Crypto‑native custody introduces a different set of practices. A crypto‑custodian typically stores private keys and may provide technologically oriented safekeeping, multi‑party computation (MPC) or hardware security modules (HSM). Where tokenised securities represent shares in a fund or asset, crypto‑custody firms combine digital key management with legal frameworks (custody agreements, insurance and indemnities) so that digital control maps back to recognised legal title.

Hybrid custody structures are increasingly used for fractional real‑asset products: legal title is held by a conventional nominee or trustee while token custody and operational transfer occur via a regulated or supervised custodian. Each model has trade‑offs: nominees and trustees offer legal clarity and creditor protection; crypto‑custodians can enable fast transfers and programmatic rights but require robust contractual mapping to UK property and company law.

For retail investors considering fractional digital shares in property or renewables, transparency about which custody model is used, who bears custody risk, insurance arrangements and how legal title is documented matters for assessing practical investor protections and recovery pathways.
