What happens to assets if an intermediary runs into trouble depends on the quality of custody

In plain words

Custody is the professional safekeeping of a client’s assets and the keeping of records of them. A custodian is an institution that does this: usually a bank or a specialised company. Put simply: your securities and assets are held by a reliable custodian, not “somewhere at the broker’s”.

The key idea is segregated record-keeping. Clients’ assets are recorded separately from the custodian’s own assets. This is what protects your rights if an intermediary runs into trouble: clients’ assets must not be mixed with its property. The custodian also records transactions, handles settlement of trades and keeps supporting documents.

The subject has become more prominent with the growth of digital assets, where custodial and non-custodial holding are distinguished: in the first case the provider controls the keys, in the second you do. Each option has its own risk logic: in one you depend on the institution’s reliability, in the other entirely on your own discipline in keeping the keys.

What you need to know

  • Clients’ assets are recorded separately
  • A custodian holds and records, but does not manage the portfolio
  • The custodian’s jurisdiction affects your rights
  • In digital assets custodial and non-custodial holding are distinguished
  • Succession arrangements for the assets are worth confirming in advance

Common mistakes

  • Not asking where and how your assets are held
  • Assuming the custodian manages your money
  • Ignoring the custodian’s jurisdiction
  • Not arranging access for heirs
  • Holding large digital assets without a well-thought-out arrangement

What this means for a BRIDGES client

When you relocate, we look not only at taxes but also at where and how your assets are held: the custodian’s jurisdiction affects both your rights and succession. These questions are cheaper to clarify before the move than to sort out later.

Frequently asked questions

01 /What is custody, in plain words?

The professional safekeeping and record-keeping of your assets by a third party — usually a bank or a specialised company.

02 /Does the custodian manage my money?

No. Its job is to hold the assets and keep records of them. Managing the portfolio is a separate function and a separate agreement.

03 /Why are segregated records needed?

So that your assets are not mixed with the intermediary’s own property. This protects your rights if it runs into trouble.

04 /How does custodial holding differ from non-custodial?

With digital assets, under custodial holding the provider controls the keys; under non-custodial, you do. The risks differ: trust in an institution versus your own discipline.

05 /Does the custodian’s jurisdiction matter?

Yes. It determines the applicable law, how disputes are resolved and the rules on inheriting the assets.

06 /What will happen to the assets after my death?

It depends on the agreement and the jurisdiction. It is worth clarifying and arranging this in advance rather than leaving it as a task for your heirs.
