Third-Party Custody

Concept and Nature of Third-Party Custody

Die Third-Party Custody is a legal term from German civil law and also applies within the European and international context, referring to the fiduciary or secure custody of objects, rights, or assets by a third party independent of the actual contracting parties. Third-party custody primarily serves the purpose of securing assets outside the immediate control of the transaction participants, thus protecting the interests of all parties during pending legal or contractual relationships.

Legal Basis of Third-Party Custody

National Regulations in Germany

Under German law, third-party custody is not a separately regulated type of contract, but rather a fiduciary position based on law, contract, or judicial order. It may occur under various legal provisions:

  • § 372 et seq. BGB – Deposit: The judicial or official custody of money, securities, or other assets at a public institution (e.g., court treasury) constitutes a form of third-party custody.
  • § 929 Sentence 1 BGB – Possession Mediation Relationship: Third-party custody can be structured as a so-called possession mediation relationship, for example, in the context of ownership transfers where possession of items is mediated via a third party (so-called “Besitzkonstitut”).
  • Trust Relationship: Third-party custody is a typical case of a trust, in which the third party holds the object or right in their own name but in the interest of another.

European and International Regulations

In international commercial transactions, third-party custody is often governed by escrow agreements (trust agreements). In this context, the following apply:

  • UN Sales Law (CISG)
  • Trade Usages (Usances)
  • ESCROW provisions in Anglo-American legal systems

as the relevant legal frameworks for the structuring and enforcement of such agreements.

Types and Areas of Application of Third-Party Custody

Judicial and Official Third-Party Custody

A typical form of third-party custody is judicial deposit pursuant to §§ 372 et seq. BGB. It serves to fulfill obligations or secure disputed claims by having the debtor transfer the owed service to the court or another deposit office. Release is made according to judicial order once the legal situation has been clarified.

Third-Party Custody in Sale and Delivery Transactions

In commercial transactions, third-party custody is often used to protect the interests of both buyer and seller, especially where legal or factual uncertainties exist regarding delivery and payment. In this context, escrow agreements are particularly significant in international transactions.

Third-Party Custody in Real Estate Transactions

In the context of real estate transactions, third parties such as notaries (under BNotO, BeurkG) hold the purchase price in trust until all prerequisites for the transfer of ownership are met. Only after registration of the buyer in the land register is payment made to the seller.

Third-Party Custody under Insolvency Law

In insolvency proceedings, third-party custody can serve to secure items that are initially to be removed from creditors’ access (separate estate, rights of segregation). This includes items in the possession of service providers whose property is not part of the insolvency estate and whose custody is held in trust for those entitled to preferential satisfaction.

Rights and Duties of the Custodian

Standard of Care and Liability

The third party entrusted with third-party custody is subject to increased duties of care and safekeeping. They must protect the deposited items from loss, damage, and access by third parties. In the event of a culpable breach of these duties, the custodian is liable to the entitled party for compensation pursuant to § 280 BGB or the provisions of the individual custody contract.

Right to Demand Return

Upon cessation of the reason for custody or upon occurrence of a condition, the third-party custodian is obligated to return the deposited item to the entitled party or to the party legally determined. In the case of judicial deposit, release occurs only by court order.

Right to Remuneration

Whether and to what extent the third-party custodian is entitled to remuneration depends on the custody contract or statutory provisions (§ 688 et seq. BGB – custody contract), as well as any applicable provisions of public law (e.g., court cost statutes).

Termination of Third-Party Custody

Third-party custody generally ends upon fulfillment of the deposited condition, completion of the managed legal transaction, or by releasing the deposited object. Cancellation or reversal must be effected in accordance with the relevant law or contractual provisions.

Distinctions and Related Legal Institutions

Distinction from Simple Custody

Third-party custody is to be distinguished from mere deposit or custody as per § 688 BGB, in which the custodian acts directly for a principal, without a specific triangular relationship involving binding to other parties.

Difference to Trusts and Pledges

While a trust encompasses broader powers and regularly includes rights of management and disposal over the asset, third-party custody is generally limited to mere safekeeping. In contrast to pledging, third-party custody does not serve to secure a claim, but primarily neutrality and safeguarding interests during a state of legal uncertainty.

Practical Significance and Risks of Third-Party Custody

Third-party custody is of considerable significance in commercial transactions and in general contract law, particularly for ensuring provisional possession and safeguarding the interests of all parties involved in transactions that require enhanced security. Risks arise from cases of misuse, unclear contract arrangements, or insufficient creditworthiness of the third-party custodian. Therefore, a clear and comprehensive contract regarding third-party custody is of central importance.

Summary

Third-party custody is an important legal institution for the fiduciary protection and administration of objects or rights by an independent third party. It ensures neutrality and protection of participating interests during legal, contractual, or judicial transitional states. The structuring and enforcement of rights and duties within the framework of third-party custody are subject to German civil law, European and international standards, and the principles of sound business management.

Frequently Asked Questions

What legal requirements must third-party custodians meet under German law?

Third-party custodians in Germany are subject to various legal requirements, especially when it comes to the custody of financial instruments, securities, or assets. Fundamentally, the German Civil Code (BGB) applies, which contains provisions on custody agreements in §§ 688 et seq. In the case of commercial custody of, for example, securities, special statutory provisions also apply—particularly the Depotgesetz (DepotG) and the Kreditwesengesetz (KWG). Third-party custodians often require express authorization from the Federal Financial Supervisory Authority (BaFin), especially if banking or financial services as defined in § 1 para. 1 KWG are performed. Moreover, they are subject to additional duties, such as the segregation of own and client property, transparency and information requirements, as well as strict accounting and due diligence standards. Noncompliance with these requirements can render contracts void and result in criminal and regulatory consequences.

Which contracts are mandatory for third-party custody?

From a legal perspective, the conclusion of a custody contract pursuant to § 688 BGB is regularly necessary in the case of third-party custody. This contract must detail the rights and obligations of both parties—the custodian and the depositor. For certain items, such as securities or precious metals, additional specific contracts—such as deposit agreements for securities—may be required. If third-party custody is offered on a commercial basis, special contractual contents are also prescribed by the German Commercial Code (HGB) and where applicable, the Depotgesetz, such as provisions on insurance coverage, liability scope, termination modalities, and release of stored items. Written form is not always mandatory but is highly recommended for evidentiary purposes.

What liability does the third-party custodian have in the event of damage?

The third-party custodian is fundamentally liable for fault-based breaches pursuant to § 690 BGB for the proper custody of the entrusted property. For negligent or intentional violations of the custody duties (e.g., improper storage, mixing own and client assets), the custodian is fully liable for resulting damages. For particularly vulnerable items or where a higher standard of care (so-called “obligation to safeguard”) has been agreed, the requirements are increased. In addition, contractual limitations of liability can be agreed provided they do not contravene mandatory legal provisions. In case of commercial custody, special statutory liability rules (such as those in the DepotG or HGB) may also apply, which may impose stricter liability, reverse the burden of proof, or require the conclusion of insurance.

How is the third-party custodian’s obligation to release the deposited asset governed by law?

According to § 695 BGB, the third-party custodian is obliged to return the deposited good at any time upon request of the depositor unless otherwise contractually agreed. This obligation to return generally exists even if the custody contract is for a fixed term or subject to special conditions, provided a legitimate interest of the depositor in the return exists. In the case of commercial custody, for example by banks, even more specific provisions regarding return, deadlines, and segregation in insolvency cases must be observed. Legal peculiarities arise if items were stored without marking, as in such cases the return must be by type and standard; otherwise, a right of subrogation may apply.

What happens to the deposited assets in the event of insolvency of the third-party custodian?

In the event of insolvency of the third-party custodian, the depositor’s right of segregation according to § 47 InsO comes into play. As a general rule, items that remain the property of the depositor and have been sufficiently individualized or separately stored (so-called open custody) must be segregated from the insolvency estate and released to the entitled party. In cases of collective custody or commingling, complex individual issues regarding security ownership, co-ownership, or in some scenarios, fractional rights may need to be addressed. Additional special rules apply to the custody of securities and crypto assets, where securities law, and since 2023, the custody of crypto tokens in Germany, are subject to their own insolvency law protection provisions.

What information and accountability obligations do third-party custodians have?

Third-party custodians are subject to extensive information and accountability obligations towards the depositor. According to § 666 BGB, the custodian must, upon request, provide the depositor at any time with information about the custody and condition of the deposited item and deliver a full account upon termination of the custodial relationship. In the case of commercial custodians—especially banks or specialized securities custodians—further periodic reporting and information obligations are prescribed by the DepotG, KWG, or by regulatory provisions of BaFin. Failure to fulfill these obligations can give rise to claims for damages or even regulatory actions.

Is sub-custody (transfer to sub-custodians) legally permissible?

Transferring the deposited items to a sub-custodian (‘sub-custody’) is generally only permitted under German law if either the purpose of the custody requires it or the depositor has expressly consented (§ 691 BGB). In addition, the main custodian is liable for culpable selection of the sub-custodian and thus also liable for their faults and breaches of duty. If particularly valuable or sensitive items are transferred to a sub-custodian, higher requirements for diligence and control apply. In securities custody and account management, sub-custody is common in economic terms and is legally regulated in the respective special laws, particularly regarding reporting and approval obligations.
