Securing a mortgage through a trust, company, offshore entity, Special Purpose Vehicle (SPV), or Family Investment Company (FIC) requires a level of documentation far beyond what borrowers provide in personal-name applications. This is not because lenders are difficult, but because these structures introduce layers of governance, ownership, and legal authority that must be verified before any charge can be placed over a UK property.

In 2025, UK lenders—particularly private banks—are more familiar than ever with sophisticated ownership structures. They frequently lend to offshore companies, family trusts, investment vehicles, and multi-jurisdictional entities, as explained in our guide on how private banks lend to offshore companies. But familiarity does not reduce the need for detailed, accurate paperwork. In many cases, the success of the mortgage depends on whether documents are prepared, certified, and consistent before a lender begins their legal review.

Willow Private Finance works with trust-owned structures, company borrowers, offshore SPVs, and complex family entities almost daily. Whether clients are purchasing through a FIC, as explored in our guide to FIC mortgages, or through long-standing offshore trusts, the underwriting themes remain the same: lenders must understand who they are lending to, who controls the structure, and how authority to borrow is granted.

This guide explains the exact types of documents lenders expect in 2025, why each one matters, the common issues that delay applications, and how families, trustees, and directors can prepare early to avoid timeline problems.

Why Documentation Matters More for Trusts and Companies

A mortgage in a trust or company’s name involves far more than verifying identity and income. Lenders must be satisfied that the entity has the legal right to borrow, grant a charge, and take on long-term obligations. When the borrower is a trust or company, lenders cannot rely on the same assumptions they make for individuals—there is no automatic authority to mortgage assets unless it is expressly written into the structure’s governing documents.

For trusts, lenders need to confirm that trustees have explicit power within the trust deed to borrow money, grant security, and acquire property. Even with these powers, trustees often need to produce specific resolutions authorising the transaction. If any beneficiaries are minors, lenders need assurance that adults retain full authority and decision-making control.

For companies, lenders examine the articles of association, share structure, and director authority. Many companies—particularly FICs, offshore entities, and dormant SPVs—require updated resolutions or amendments before a mortgage can proceed.

A secondary reason documentation is critical is regulatory. Anti-money-laundering (AML), Know Your Customer (KYC), and global transparency rules have all tightened. Lenders must prove the legitimacy of the structure, the transparency of ownership, and the legality of the money used. These checks are not optional; they are regulatory requirements. Missing or inconsistent documents can halt an application entirely.

What Lenders Review for Trust-Owned Mortgages

For trust-owned property, lenders require a comprehensive understanding of the trust’s origin, purpose, and current governance. The starting point is the trust deed, including all supplemental deeds. This is the foundational document that outlines the powers of trustees, the beneficiaries, and the structure of decision-making.

Lenders also routinely request beneficiary registers. They must identify each individual who may benefit from the trust, even if their interests are discretionary. Where minors are beneficiaries, lenders must determine whether their involvement affects borrowing authority.

Trustees then need to provide formal resolutions. These resolutions must confirm that the trustees agree to the mortgage, approve the acquisition, authorise named signatories, and confirm that the transaction is within their powers. Without these, lenders cannot proceed.

Additionally, lenders need documentation proving the trust’s financial position. This may include statements of investment portfolios, cash accounts, or underlying company holdings. If the trust owns a company (a common structure for international families), the lender may also need the corporate documents of that company.

Source-of-wealth evidence is also required for the trust settlor or the individuals whose resources are supporting the mortgage. These documents help lenders validate the origin of funds used for deposits or ongoing repayments.

What Lenders Review for Company or SPV Mortgages

When property is owned through a company or SPV, UK lenders must confirm the entity’s legitimacy, ownership, financial position, and borrowing authority. The review begins with the company’s certificate of incorporation and extends into its articles of association. Articles must allow the company to borrow and to grant charges over assets. Many companies, especially SPVs created specifically for property purchase, already include these powers, but older or more complex companies may require amendments.

Lenders also review the company’s share structure and shareholder register. They must identify every individual who owns the company, even if ownership is split across multiple entities. Where a company is owned by another company, lenders must trace ownership until they reach the individuals behind the structure.

Directors’ authority is equally important. Lenders need to confirm that directors have the power to bind the company into long-term borrowing. This often requires a board resolution confirming the approval of the mortgage and authorising specific directors to sign legal documents.

If the company is trading or if it owns other assets, lenders may request financial statements or management accounts. Even if the company does not require income for affordability—in cases where lending is based on wealth or rental performance—lenders must understand its financial condition.

Documentation becomes more complex when the company is part of a wider structure, such as a FIC or trust-owned SPV. In these cases, lenders may need documents from multiple layers of ownership to verify authority and transparency.

The Importance of KYC, AML, and Ownership Transparency

Regulatory compliance has evolved significantly over the past decade. In 2025, it is no longer enough to disclose partial ownership or limited information. Lenders must understand the full ownership structure, including individuals who indirectly control the entity.

This means that everyone involved—beneficial owners, directors, trustees, settlors, and major shareholders—must provide certified identification and address verification. Even if an individual has no direct involvement in the mortgage, if they hold shares or exert control over the structure, they must be disclosed.

AML checks extend beyond identity. Lenders must also verify the origin of funds, especially deposits, capital injections into the company, or assets held in trust. This includes bank statements, investment reports, business documentation, or audited accounts showing how wealth was generated.

International clients must provide documentation that meets UK certification standards. Apostilles, notarisation, and formal translations may be required for non-UK documents.

Why Private Banks Handle Documentation More Effectively Than Mainstream Lenders

Private banks are accustomed to reviewing complex documentation packages. Their clients routinely use trusts, FICs, SPVs, and offshore companies to manage global wealth. As a result, private banks maintain specialist teams who review trust deeds, corporate documents, and multi-layer structures regularly.

Unlike mainstream lenders—whose frameworks assume single-income UK borrowers—private banks understand the commercial logic of advanced structures. They interpret documents within the broader strategy of the family or business rather than rigid checklists.

Private banks also assess wealth differently. Instead of focusing on income or rental yield, they evaluate investment portfolios, liquidity, business interests, and global wealth. This is why many trust and company mortgages are completed through private banks, as highlighted in our article on how wealthy buyers borrow using assets instead of income.

Documentation, therefore, becomes a facilitator—not a barrier—when dealt with by a lender that understands the context.

Common Document-Related Issues That Delay Trust and Company Mortgages

Most delays occur not because lenders are slow, but because structures were not prepared or reviewed before an application began. For trusts, missing borrowing powers in the deed are one of the most common issues. Without these powers, trustees cannot legally grant a mortgage.

For companies, outdated articles or missing shareholder registers cause significant delays. Similarly, companies with complex share structures often require additional clarification before lenders can verify ownership.

Another recurring issue is incorrect certification. Lenders require documents to be certified by approved professionals, and international clients frequently provide documents that do not meet the required standard—necessitating re-certification.

Finally, large structures involving multiple companies or trust layers can create timing challenges. If a lender needs documents from all layers of ownership, delays can accumulate unless all parties are coordinated.

How to Prepare Documents Efficiently in 2025

The most successful applications are those where preparation begins early—even before an offer is accepted. Engaging trustees, directors, accountants, and company administrators early makes a dramatic difference to timelines.

Families with FICs or multi-layer structures should review their articles or trust deeds in advance, ensuring borrowing powers are present and clear. Where investment portfolios will be used to support the application, obtaining up-to-date statements is essential.

For international clients, obtaining certified translations and notarised documents ahead of time prevents delays once underwriting begins. Coordinating all relevant parties—including offshore administrators—further ensures a smooth process.

A Typical Trust or Company Documentation Hypothetical Scenario

Consider a family acquiring a £3 million London property through a long-established trust. The trustees are professionals based offshore, and the beneficiaries are spread across multiple countries. A private bank requires the trust deed, supplemental deeds, a full beneficiary register, certified trustee IDs, and resolutions authorising the purchase. The bank also requests investment statements showing the trust’s liquidity. Without early coordination, this documentation could take weeks to assemble. When managed well, it can be completed in days.

Another example involves a UK FIC acquiring an investment property. The lender requires the company’s incorporation documents, shareholder registers, director IDs, resolutions, and evidence of personal guarantees from voting shareholders. These documents often reveal that amendments are needed—such as updating share registers or adding borrowing authority. Preparing these documents early ensures the lender can proceed without interruption.

Outlook for 2025 and Beyond

As family wealth structures become more sophisticated, lenders will continue to refine their document requirements and increase their expectations around transparency. Trusts and companies will remain popular ownership vehicles, but borrowers must be prepared for greater scrutiny.

The positive news is that private banks and specialist lenders are expanding their capabilities in this area. Documentation is becoming better understood, and underwriting is increasingly aligned to global wealth management rather than UK-specific income models.

Borrowers who prepare early, coordinate their advisors, and work with specialist brokers will secure the best terms and fastest timelines.
