Cryptocurrency in Deceased Estates: A Practical Guide for Executors

The Modern Executor's New Asset Class

Executors appointed to administer South African deceased estates increasingly encounter cryptocurrency holdings that the deceased never disclosed during their lifetime. Where wills are silent on digital assets and family members have no knowledge of trading accounts or wallet credentials, the executor faces a recovery, valuation, and distribution challenge unlike anything contemplated in traditional estate administration practice.

This guide is written for executors, administering attorneys, and trust officers who need a practical path through the eight steps that typically arise from the moment crypto assets are first suspected to the eventual transfer to beneficiaries.

Step 1: Discovery

Few testators leave a clear inventory of digital assets. Executors should look for the following indicators during the initial estate review: bank statements showing transfers to local exchanges such as Luno, VALR, AltCoinTrader, or OVEX; bank statements showing transfers to international exchanges such as Binance, Kraken, or Coinbase; email accounts containing exchange registration confirmations, two-factor authentication backups, or trade confirmations; hardware wallets among personal effects, typically small USB-style devices manufactured by Ledger or Trezor; written notes mentioning seed phrases, which are typically 12 or 24 ordinary words written down, or private keys, which are long alphanumeric strings; and devices with cryptocurrency apps installed.

Where the deceased's spouse or family members have any knowledge of crypto activity, document this in writing as part of the estate inventory at the earliest opportunity.

Step 2: Securing the Assets Before Access

Before access is established, executors must take immediate steps to prevent loss. Secure all hardware wallets, written seed phrases, and any device that may grant access. These should be moved to the executor's possession or a secure facility. Notify identified exchanges of the death in writing. Major exchanges have deceased estate procedures that lock the account on receipt of a death notification, preventing unauthorised access pending document submission. Where there is any concern that a family member or third party may have access, change passwords on connected email accounts and revoke any device sessions if access credentials are available.

The executor's duty to preserve estate assets under the Administration of Estates Act 66 of 1965 applies as fully to digital assets as to traditional estate property. Failure to take reasonable preservation steps can expose the executor to a claim by beneficiaries for any loss attributable to the delay.

Step 3: Valuation

Valuation of crypto assets for the Liquidation and Distribution Account presents methodological choices that are not always settled in practice.

Date of Valuation

The default position is that estate assets are valued as at the date of death. For crypto assets, this requires a spot price at the date of death, typically expressed in South African Rand using a published reference rate from a major South African exchange. Where the estate is large or where values are highly volatile during administration, executors may consider a second valuation at the date of distribution to inform tax planning.

Selecting a Reference Source

Different exchanges quote different prices at the same moment due to market fragmentation. Best practice is to use the deceased's primary exchange where the holdings are exchange-held, or the volume-weighted average across major South African exchanges where holdings are self-custody. Document the chosen reference source in the L&D Account.

Valuing Illiquid or Non-Standard Assets

NFTs, governance tokens with limited trading volume, locked-up staking positions, and tokens on niche chains may not have a reliable market price. In these cases, document the valuation methodology used, whether last-traded price, comparable-sale price, or zero-value pending realisation, and disclose the methodology to the Master of the High Court if the value is material.

Step 4: Engaging South African Exchanges

The major South African exchanges have published deceased estate procedures. Typical documentation requirements include a certified copy of the death certificate, a certified copy of the Letters of Executorship issued by the Master of the High Court, a certified copy of the executor's identity document, bank account confirmation for the estate's late account, FICA documentation for the executor, and a specific deceased estate request form completed and signed by the executor.

Processing times vary from two weeks to three months. Executors should engage exchanges early in the administration process, as exchange-held assets cannot be released to the estate without completion of the exchange's process, regardless of the Letters of Executorship.

Step 5: Self-Custody Wallets

Where the deceased held cryptocurrency in a self-custody wallet, recovery depends entirely on access to the private keys or seed phrase.

If Keys Are Available

The executor, or an appointed expert acting under the executor's authority, can import the seed phrase or private key into a controlled wallet, transfer the assets to a new estate-controlled wallet, and proceed to valuation and distribution. Executors should never use the deceased's original device for these operations where possible. Restore the seed into a new device under controlled conditions to avoid contamination of evidence and to prevent unauthorised transactions on the original device.

If Keys Are Not Available

Without the seed phrase or private keys, self-custody assets are effectively unrecoverable. There is no legal mechanism to compel recovery from the blockchain, and no court order can produce keys that are not in any party's possession. Where there is reason to believe keys may exist on a device or in physical form, forensic recovery specialists may be engaged, but success rates are low and costs are significant. Executors should be candid with beneficiaries about the prospect of permanent loss rather than holding out unrealistic expectations.

Step 6: Disclosure to the Master of the High Court

The Master requires disclosure of all estate assets in the Liquidation and Distribution Account. Crypto assets must be disclosed at their valued amount, with documentation supporting the valuation methodology. The Master's offices have become increasingly familiar with crypto disclosures in recent years, but executors should anticipate questions on the valuation methodology used, the location and custody arrangements for self-custody assets during administration, and the treatment of volatility between date of death and date of distribution.

Step 7: SARS Capital Gains Tax

The South African Revenue Service treats cryptocurrency as an asset for tax purposes, with the precise treatment depending on whether the deceased held the asset as capital, subject to capital gains tax on disposal or deemed disposal at death, or as trading stock, subject to income tax. For most testator estates, crypto holdings will be capital in nature, triggering a deemed disposal at death under section 9HA of the Income Tax Act with a capital gain calculated against the original base cost.

Executors must establish the deceased's base cost in each crypto holding. This requires reconstructing transaction history from exchange records, bank statements, and any wallet transaction logs. Where base cost cannot be established, the deemed disposal will be calculated against a base cost of zero, producing an inflated capital gain that erodes the value passing to beneficiaries. Tax counsel should be engaged where holdings are material.

Step 8: Distribution to Beneficiaries

Two distribution methods are available.

Liquidation and Cash Distribution

The executor sells the crypto assets through the deceased's exchange, or for self-custody assets through an exchange to which the assets have been transferred, realises the Rand proceeds in the estate's late account, and distributes cash to beneficiaries in accordance with the will. This is the simplest method and removes the need for beneficiaries to hold crypto themselves.

In-Specie Distribution

Where the will or a beneficiary request supports it, the executor can transfer the underlying crypto asset directly to a beneficiary's wallet. This requires the beneficiary to have or to set up a wallet in advance, and to provide the wallet address in writing. In-specie distribution avoids realisation costs and may be tax-efficient where the beneficiary intends to hold long-term, but it transfers the volatility risk to the beneficiary from the moment of distribution.

Common Pitfalls

Lost seed phrases. Where the executor cannot locate keys, the assets are likely permanently lost. This is the single most common cause of crypto value destruction in estates, and is largely preventable through testator-stage planning.

Unauthorised family access. Family members who know the deceased's exchange password may attempt to access accounts after death. Notify exchanges immediately to lock accounts. Unauthorised transactions during the estate period can create liability for the family member and complicate the executor's reconciliation.

Tax base cost gaps. Reconstructing transaction history can be difficult years after the fact. Where base cost cannot be established, executors should engage with SARS proactively rather than defaulting to a zero base cost without representation.

Volatility-driven delays. Long administration periods expose the estate to price swings. Where holdings are material, consider liquidating early and holding the proceeds in an interest-bearing late account, rather than holding crypto through administration.
