Fund managers often treat custodian onboarding as a procurement step and find it is a structural review. A regulated custodian taking on a tokenized fund accepts obligations to segregate, reconcile and account for assets it must be able to identify with certainty, and it is unlikely to accept those obligations against a structure it cannot follow. In our experience the delays at this stage are rarely commercial. They come from the custodian finding that something in the fund's documentation does not resolve.

Five Areas a Custodian Will Usually Examine

A legal opinion on what the token is. Custodians generally want a defensible classification of the instrument under a named framework, because the custody obligations attaching to a security differ from those attaching to a virtual asset. An opinion that hedges across categories tends not to resolve the question being asked.

Documented title to the underlying asset. Where the fund holds real-world assets, the custodian needs to see that title sits in the vehicle the fund documents say holds it. Assets described as held but registered elsewhere are a recurring blocker.

Clean segregation of client and proprietary assets. The custodian must be able to show that fund assets are separated from its own and from those of other clients, at the account level and in the records. Where the custodian is regulated, this is an obligation rather than a preference, though the precise requirements depend on the jurisdiction, the asset and the custody mandate. ADGM, for example, applies specific safe custody obligations where an authorised person holds or controls Accepted Virtual Assets for clients.

A key management model that survives inspection. Who holds keys, under what quorum, with what recovery procedure and what happens on the departure of a signatory. Arrangements that depend on named individuals rather than documented controls can attract objections.

A clear registrar position. Legal registrar architecture varies between tokenized fund structures. Where on-chain and off-chain records coexist, the governing documents need to identify which one legally controls and how discrepancies are reconciled.

Where Review Stalls

Three patterns recur.

Structure documents and fund documents disagree. The offering document describes a holding arrangement the constitutional documents do not create. Often a drafting sequencing problem rather than a design flaw, but it can take weeks to unwind.

The custody model was chosen after the structure was built. Whether the fund uses a third-party custodian affects its own regulatory position, including capital treatment in some frameworks. Deciding it last means revisiting decisions already made.

The vehicle holding the assets is the wrong one. Where an SPV was intended to ring-fence assets but title ended up in the operating company, the custodian is being asked to hold against a structure that does not do what it claims. Our article on ADGM SPV setup covers how that vehicle is meant to work, including who the structure can issue to.

Preparing the classification opinion and title documentation before approaching custodians shortens this materially. Our tokenized fund structures and token legal opinion work is built around this review, or get in touch.

Frequently Asked Questions

Does a tokenized fund need a third-party custodian?

It depends on the framework and the fund type. Some structures permit self-custody with conditions and others require an independent custodian. The decision affects the fund's own regulatory position, so it belongs early in the structuring work rather than at onboarding.

What legal opinion do custodians ask for?

Typically an opinion classifying the instrument under a named regulatory framework, stating whether it constitutes a security or a virtual asset in that jurisdiction, and identifying the custody obligations that follow. An opinion leaving the classification open is unlikely to satisfy the question, since the custodian's own obligations turn on the answer.

Why do custodians care who holds title to the underlying asset?

Because the custodian undertakes to hold and account for assets it must be able to identify. If the asset is registered to a founder or an affiliate rather than the fund vehicle, the custodian cannot verify what it is being asked to hold.

What key management arrangements do custodians expect?

Documented controls rather than individual ones: a defined signing quorum, a tested recovery procedure, and a stated process for a departing signatory. Arrangements depending on a named person tend to be treated as a single point of failure.

What happens if the on-chain and off-chain registers disagree?

The governing documents should identify which record legally controls and how a discrepancy is reconciled. Structures vary, so there is no single correct architecture. What causes problems is leaving the hierarchy unstated, since the ambiguity has to be resolved before a custodian can account for the assets.
