Common weaknesses in lender-side documentation

A hypothetical to start. A lender advanced funds eighteen months ago on a two page term sheet. The borrower, a company, asked for more time in March and the lender agreed by text message. There was meant to be a guarantee from the director. Now the loan is overdue again, the lender wants to know where they stand, and the signed copy of the guarantee cannot be found. The lender, the company and the loan are invented for this article.

The short answer is that the lender's position needs to be assessed from the documents and the wider transaction record, including what was agreed, communicated and done at the time. Before relying on a loan file, or before a variation or a recovery step, the gaps in it should be identified: what the terms say, what secures the loan and whether that security was properly put in place, what has changed since the advance, and what the file records about each of those things. A gap is not proof that the lender has no rights. It is a question that needs an answer before anything else is decided.

Good record-keeping supports enforcement. Poor record-keeping gives room for dispute.

Terms that were never written down clearly

A loan agreement should record the essential commercial terms. The hypothetical term sheet records the amount and the rate and little else. That leaves the repayment date, default interest and what happens on default to memory and to the text messages.

Loan documents should usually make clear:

• the principal amount;
• the date of advance;
• the interest rate;
• whether default interest applies;
• repayment date or repayment mechanism;
• fees, costs, and recoverable expenses;
• events of default;
• lender rights after default;
• security being provided;
• whether guarantees are required.

Where a term is missing, the first job is to find out what the file does say about it: a term sheet, an email exchange, a ledger entry. If essential terms were left to assumption, the lender may face unnecessary argument later.

Security that was described loosely, or never completed

For lending secured over property, the security description needs to be accurate. Do not assume security was put in place merely because it was discussed. Identify what was agreed and what steps were actually taken. The lender should be able to say what was signed, what was lodged or registered, and what ranking was intended, and then check all three against the title and any priority arrangements. An existing bank mortgage on the title does not, on its own, settle where the new mortgage ranks.

Weaknesses often arise where:

• the property is not properly identified;
• existing mortgages or caveats are not considered;
• the lender assumes a better priority position than it actually has;
• guarantees are discussed but not properly documented;
• security documents are not signed or registered correctly;
• the borrower's ownership or authority is not checked.

Security over other assets, such as vehicles, equipment or receivables, is a different exercise from a mortgage over land, with its own steps and its own register. For those assets the question is what was agreed, what was signed and what was registered, and the answers need to be checked together. A registration on its own is not the whole assessment.

Supporting records that do not match the documents

Loan documents are only part of the file. Emails, term sheets, payment records, settlement statements, guarantees, advice certificates, and borrower communications may all become important if the matter later becomes disputed.

In the hypothetical, the file has a term sheet, a bank statement showing the advance, a run of text messages about the March extension, and no signed guarantee. Each of those is a record. The question for each is what it shows, and what it does not.

Problems can arise where:

• funds were advanced before final documents were signed;
• the term sheet differs from the final loan agreement;
• payment records are unclear;
• extensions or variations were agreed informally;
• default notices were not properly recorded;
• instructions were given by the wrong person;
• the file does not show what was agreed and when.

The strongest lending files are not necessarily the longest. They are the files where the transaction, the security, the borrower's obligations and the lender's rights are clearly recorded, and where a question about any of them can be answered from the file rather than from memory.

Default provisions that leave the lender guessing

A lender should know what constitutes default and what rights arise after default. If default provisions are vague or incomplete, the lender may have fewer practical options or may face arguments about whether enforcement steps were properly triggered.

Default provisions commonly deal with:

• failure to pay;
• breach of loan terms;
• insolvency events;
• misrepresentation;
• deterioration of security;
• unauthorised dealings with secured property;
• failure to provide required information;
• enforcement costs and recovery expenses.

The documents should also make clear what notice is required, what timeframe applies, and what the lender can do if the default is not remedied. The agreement is not the only source of those requirements. Check the agreement and any applicable statutory notice requirements before taking an enforcement step.

Guarantees that exist in conversation but not on the file

Where a lender expects additional protection from a guarantor, the guarantee should be properly documented. Informal assurances from related parties may not be enough. The lender should be able to identify the guarantor, the obligations guaranteed, and the signed record.

Issues can arise where:

• the guarantor is not clearly identified;
• the guarantee is not signed correctly;
• the guaranteed obligations are not properly described;
• independent advice was expected for the transaction but not arranged;
• the guarantor later says they did not understand the obligation;
• the guarantee does not match the loan agreement.

Back to the hypothetical. A guarantee that cannot be found is an information gap. It does not mean no guarantee exists, and it does not mean a claim against the director would fail. It means the lender needs to establish what was signed, by whom, when, and where the record is, before anyone relies on it or writes it off.

Variations that were agreed but never recorded

Many disputes arise after the original loan terms are changed. Extensions, additional advances, changed repayment dates, increased interest, changed security, or revised default arrangements should be recorded properly.

A lender should be cautious about relying only on informal emails, text messages, or verbal discussions. Where the loan structure changes, the documents may need to be updated.

Common examples include:

• extending the repayment date;
• increasing the loan amount;
• changing the interest rate;
• adding or releasing security;
• agreeing a repayment plan;
• capitalising unpaid interest;
• waiving or reserving rights after default.

For each change the useful record answers four questions: what changed, when, who agreed, and how it was recorded. The text messages in the hypothetical record the March extension. The lawyer needs those messages and the original documents to assess what was agreed, how it was recorded and whether any further documentation was needed.

What to have ready

• the loan agreement or term sheet, and every version of it;
• security documents, and anything showing what was lodged or registered;
• the guarantee, or whatever record of it exists;
• the payment ledger and bank records of the advance;
• every message about an extension, variation or repayment plan;
• any default notice or demand already sent;
• a short chronology: what happened, when, and who was involved.

Have these ready. Before sending documents or confidential details, ask the firm what it needs and how they should be supplied for its conflict check and intake process.
