A physical gold due diligence checklist helps large buyers verify the bullion, seller, custody structure, logistics, and records before capital moves.
For high net worth investors, family offices, trustees, and private wealth buyers, due diligence is not paperwork clutter. It is the process that turns a gold purchase into an auditable custody file.
This guide explains the main due diligence steps for large physical gold purchases, Swiss vault storage, LBMA-recognized bullion, insured delivery, and long-term ownership records.
Physical Gold Due Diligence Checklist for Large Buyers
A physical gold due diligence checklist should begin before the buyer asks for a price.
Large bullion purchases involve more than spot exposure. The buyer must confirm who owns the gold, where it comes from, how it will be stored, and what records will prove ownership later.
For a family office or trustee, those details can matter years after the transaction closes. A weak file can create problems during audits, estate reviews, insurance claims, resale, or vault transfers.
Therefore, due diligence should cover the full process from mandate to final storage statement.
Start With the Physical Gold Due Diligence Mandate
The buyer should first define the purpose of the gold purchase.
Some buyers want a long-term wealth preservation reserve. Others want jurisdictional diversification, liquidity planning, or an asset outside the ordinary banking system.
The mandate affects bar format, custody structure, vault location, reporting needs, and future sale procedures.
If the buyer does not define the purpose first, later decisions can become inconsistent.
Mandate Questions for Physical Gold Due Diligence
- Is the gold a long-term reserve asset?
- Will the gold support jurisdictional diversification?
- Does the buyer expect partial sales later?
- Will heirs, trustees, or advisers need access to records?
- Should the gold be stored in Switzerland or another jurisdiction?
- Does the buyer want allocated, segregated, or pooled storage?
For the broader framework, see our Institutional Gold Guide.
Confirm the Legal Buyer
Before buying physical gold, the buyer should confirm who will legally own the asset.
The owner may be an individual, trust, company, foundation, or family office entity. The correct structure depends on legal, tax, and estate planning advice.
This page does not provide legal or tax advice. However, the ownership structure affects onboarding, funding, custody records, authorized signers, and succession planning.
For large transactions, the account structure should be clear before funds move.
Ownership Records for Physical Gold Due Diligence
- Individual identification documents
- Entity formation records
- Trust or foundation documents, if applicable
- Board approval or investment committee approval
- Authorized signer list
- Beneficial ownership records
- Adviser or trustee contact information
Physical Gold Due Diligence and Compliance
Large gold purchases usually require compliance review. That is normal for serious financial activity.
The Swiss Financial Market Supervisory Authority explains that financial intermediaries must follow due diligence and reporting requirements to help prevent money laundering.
The Swiss Anti-Money Laundering Act also addresses recordkeeping and clarification duties for covered financial intermediaries.
For the buyer, clean compliance preparation can reduce delays and improve execution certainty.
Compliance Items for Physical Gold Due Diligence
- Government identification
- Proof of address
- Source-of-funds documentation
- Beneficial ownership details
- Entity documents
- Trust documents, if relevant
- Purpose of transaction
- Expected storage and transaction activity
Physical Gold Due Diligence for the Seller
The buyer should review the seller before reviewing the quote.
A serious provider should explain pricing, bar source, settlement process, storage options, insured logistics, and final records. It should also be clear about fees and operational steps.
The buyer should avoid relying only on a sales conversation. Key terms should appear in written documents.
If the provider cannot explain custody, allocation, insurance, or resale procedures clearly, the buyer should slow down.
Seller Questions for Physical Gold Due Diligence
- How long has the provider handled physical bullion transactions?
- Does the provider support Swiss vault storage?
- Can the provider arrange insured delivery?
- Can the provider supply serial-numbered bar records?
- How are prices, premiums, and fees disclosed?
- What happens if the buyer later wants to sell or transfer the gold?
Physical Gold Due Diligence for Bar Quality
Physical gold due diligence should include bar quality.
The buyer should know whether the purchase involves LBMA Good Delivery bars, kilo bars, smaller bars, coins, or mixed holdings.
The LBMA Good Delivery Current List for Gold identifies refiners whose bars have met LBMA standards for the global OTC market.
Recognized bullion can support future resale, transfer, and verification. However, the buyer still needs matching records.
Bar Quality Checklist
- Refiner name
- Serial number
- Bar format
- Gross weight
- Fine weight
- Fineness
- Assay or purity reference
- Purchase invoice
- Storage confirmation
For more detail, read our guide to LBMA Approved Gold Bullion for Large Purchases.
Physical Gold Due Diligence for Responsible Sourcing
Responsible sourcing may also matter for larger buyers.
The LBMA Responsible Gold Guidance is based on OECD due diligence guidance, as well as KYC, anti-money laundering, and combating terrorist financing regulations.
Private buyers are not refiners. However, they can still ask whether the gold comes from recognized channels and whether the provider can document the source and chain of custody.
For family offices, responsible sourcing questions may also support internal investment committee review.
Responsible Sourcing Questions
- Is the refiner recognized by a major market standard?
- Can the provider explain the source of the bars?
- Does the provider have responsible sourcing policies?
- Are recycled, newly mined, or secondary-market bars involved?
- Can the chain of custody be documented?
- Would the records satisfy an adviser, trustee, or auditor?
Physical Gold Due Diligence for Allocated Storage
The buyer should know whether the gold will be specifically allocated or held as a general claim.
Allocated gold usually means specific bars or coins are assigned to the buyer. Unallocated exposure may represent a claim for metal rather than direct ownership of identified bars.
For long-term custody, many high net worth buyers prefer allocated gold because it can create clearer ownership records.
However, the storage agreement should define the treatment in writing. Terms can vary between providers.
Allocation Checklist
- Will specific bars be assigned to the buyer?
- Will the buyer receive a full bar list?
- Will serial numbers appear in the records?
- Will the bars be held in the buyer’s name or entity name?
- Can the buyer sell or transfer specific bars?
- What happens if the provider fails?

Physical Gold Due Diligence for Segregated Storage
Storage structure is another due diligence point.
Segregated storage usually means the buyer’s specific metal remains separate from other client holdings. Pooled storage may hold equivalent metal within a shared inventory.
Neither term should be accepted without reading the storage agreement. The buyer should confirm how the provider defines each structure.
This matters for audits, estate files, withdrawals, and future transfers.
Storage Structure Questions
- Is the storage allocated, segregated, pooled, or unallocated?
- Does the buyer receive specific bar records?
- Are other client holdings mixed with the buyer’s holdings?
- Can the buyer inspect or audit the holding?
- Can the buyer withdraw the exact bars listed?
- How are discrepancies handled?
For more detail, see Segregated vs Pooled Vault Storage.
Physical Gold Due Diligence for Swiss Vault Storage
Swiss vault storage can support jurisdictional diversification, private custody, and long-term documentation.
However, the country name alone is not enough. The buyer should review the actual vaulting terms.
Important items include storage type, insurance, audit rights, access procedures, withdrawal rules, sale options, and reporting frequency.
The best storage file should make the buyer’s rights easy to understand.
Swiss Vault Storage Due Diligence Checklist
- Storage agreement
- Vault location
- Allocated or segregated treatment
- Insurance limits and exclusions
- Audit or inspection rights
- Access and withdrawal procedures
- Sale or transfer process
- Reporting schedule
- Annual storage fee schedule

Physical Gold Due Diligence for Insurance
Insurance should be reviewed before settlement and delivery.
The buyer should know whether insurance applies during transit, after vault receipt, or both. The buyer should also understand exclusions, valuation methods, and coverage limits.
Large bullion purchases can create risk during movement. Therefore, the handoff from seller to carrier to vault should be documented.
If the provider cannot explain insurance clearly, the buyer should ask more questions.
Insurance Questions to Ask
- Who insures the gold before shipment?
- Who insures the gold during transit?
- When does storage insurance begin?
- What valuation method applies?
- Are there exclusions or coverage limits?
- Can the buyer receive written insurance evidence?
Physical Gold Due Diligence for Chain of Custody
Delivery is where operational risk can appear.
The buyer should know when title transfers, who controls the metal, who insures movement, and who confirms final receipt.
For large purchases, every handoff should produce a record. Those records can matter later during an audit, insurance claim, transfer, or resale.
In plain terms, the buyer should be able to trace the gold from purchase to vault.
Chain-of-Custody Checklist
- Purchase invoice
- Trade confirmation
- Bar list
- Packing or transfer record
- Carrier or logistics confirmation
- Insurance confirmation
- Vault receipt
- Final storage statement
Physical Gold Due Diligence for Pricing and Fees
Due diligence also includes pricing review.
The buyer should understand the spot reference, premium, spread, settlement timing, currency, storage fees, and future liquidation costs.
At scale, a small difference can become meaningful. However, the cheapest quote may not produce the strongest outcome.
A better comparison should include bar quality, provider reliability, custody structure, and final documentation.
Pricing Items to Confirm
- Spot or benchmark reference
- Dealer spread or premium
- Currency used for settlement
- Wire deadline
- Storage setup fee
- Annual storage fee
- Insurance costs
- Future sale or transfer fees
For transaction mechanics, read our Bulk Gold Purchase Guide.
Final Physical Gold Due Diligence Checklist
Before approving the transaction, the buyer should assemble a final checklist.
This file should be clear enough for a trustee, adviser, auditor, or heir to understand later.
The goal is not only to complete the purchase. The goal is to create a durable ownership record.
- Mandate and purpose documented
- Legal owner confirmed
- Compliance file prepared
- Seller reviewed
- Bullion format confirmed
- Refiner and bar records reviewed
- Allocation terms documented
- Storage structure confirmed
- Insurance reviewed
- Delivery path documented
- Pricing and fees understood
- Final vault records received
Common Physical Gold Due Diligence Mistakes
Large buyers can make mistakes when the process moves too quickly.
The most common errors involve vague custody terms, incomplete records, weak insurance review, or too much focus on price.
These issues may not appear immediately. They often appear later when someone needs to verify, sell, transfer, or inherit the gold.
- Only comparing price: A low quote can hide weak custody terms.
- Ignoring ownership structure: The wrong account setup can complicate later reporting.
- Accepting vague allocation language: Buyers should know whether specific bars are assigned.
- Skipping insurance review: Transit and storage coverage should be clear.
- Failing to preserve records: Final records should connect invoice, bars, delivery, and storage.
Physical Gold Due Diligence Checklist Summary
A physical gold due diligence checklist helps large buyers avoid preventable problems.
The buyer should verify the owner, provider, bullion, compliance file, storage terms, insurance, delivery path, pricing, and final records before treating the transaction as complete.
For high net worth investors and family offices, this discipline can make the gold easier to audit, transfer, insure, sell, or explain later.
That is the real purpose of due diligence. It protects the buyer’s future options.
