The Evidential Value of Commercial Books

The Evidential Value of Commercial Books: Potential Adversity and Consequences for a Merchant in Court Cases

Introduction: Business Ledgers Are Not Just for Taxes, They Speak in Court Too

In commercial life, many traders often view bookkeeping as merely a formality for the tax office or financial advisor. However, according to the Turkish Commercial Code ("TCC") and the Code of Civil Procedure ("CCP"), commercial books are extremely important documents that can become strong evidence, both for and against the trader, when a dispute is brought to court

Accurate, complete, and properly kept commercial ledgers can facilitate a merchant's ability to prove their claims; they play a critical role in collecting receivables and refuting the opposing party's defenses. Conversely, incomplete and improperly kept ledgers, or the absence of ledgers at all, weaken the merchant's ability to prove their claims , and the entries in these ledgers may, under certain circumstances, evidence against .

This article will examine the "Evidential Value of Commercial Books" in detail, its implications for and against a merchant in court . The article is intended as a guide for merchants, accounting departments, and individuals seeking redress in commercial disputes.

1. What is a Commercial Ledger? Which Ledgers are Considered Commercial Ledgers?

To understand the evidentiary value of commercial ledgers, it is first necessary to explain which ledgers are considered "commercial ledgers.".

According to the Turkish Commercial Code, every merchant is obligated to keep certain mandatory books that clearly demonstrate the economic and financial status of their business, their debt and receivables relationships, and the results obtained each business year. The most well-known and widely used basic commercial books in practice are as follows:

The journal (daily ledger): This is the fundamental ledger of accounting, recording every transaction made by the business in chronological order.
The general ledger is a ledger in which transactions recorded in the journal are aggregated by account.
Inventory ledger: This is a ledger in which a company's movable and immovable assets, receivables and payables, stocks, etc., are meticulously counted and valued.
Share register, general assembly meeting and deliberation register, board of directors resolution register (for companies): These registers show the ownership structure and internal decision-making processes of capital companies.

In addition, depending on the size of the business, its field of activity, or the preferred accounting system, auxiliary ledgers (inventory ledger, cash ledger, current account auxiliary ledgers, etc.) may also be used. However, not every auxiliary ledger is necessarily a "legally required commercial ledger" on its own. When evaluating evidentiary value, ledgers that are legally required to be kept are given priority.

2. The Obligation of a Merchant to Keep Commercial Books and Its Legal Basis

In Turkish law, the basis for a merchant's obligation to keep accounting records is primarily the Turkish Commercial Code (TTK) and relevant tax legislation. In summary:

Every merchantis required to keep commercial books that accurately reflect the activities, assets, and financial status of their business.
Records in Turkish, neatly, accurately, timely and that cannot be altered .
The ledgers certified at opening and closing , kept , and made available to the court or expert witness upon request.

This obligation is important not only from a tax perspective but evidence in judicial proceedings . Courts, when evaluating the veracity of a trader's claims, make extensive use of properly kept commercial ledgers.

3. The Legal Framework of the Evidential Value of Commercial Books

The basic regulation regarding the evidentiary value of commercial books is found in the Code of Civil Procedure (HMK) . Commercial books, under the conditions stipulated by law:

Evidence in favor of the merchant,
Evidence against the merchant,
Sometimes, discretionary evidence supports the opposing side's claim.

It can be considered as such.

3.1. General Requirements for Using Commercial Books as Evidence

For a business ledger to be used as evidence in court, the following criteria are generally required:

Being kept by a merchant: The person or company keeping the ledger must be a merchant. Records kept by a non-merchant cannot be considered a commercial ledger; at most, they may be classified as a private note or ordinary document.
Having been properly kept:
- The ledgers must be of the type required by law
- Opening and closing confirmations must be completed on time
- Records must reflect the truth
- The records must be free from any breaks, erasures, alterations, or falsifications.
The existence of a commercial transaction or commercial relationship between the parties: Commercial ledgers have high evidentiary value, especially commercial disputes . In a purely personal legal relationship, the role of commercial ledgers may be more limited.
Accounting records should corroborate each other: Basic accounting books such as the journal, general ledger, and inventory book are expected to contain entries that support each other.

Commercial ledgers that meet these conditions acquire a certain degree of binding force, both in favor of and against the merchant.

4. The Evidential Value of Commercial Books in Favor of the Merchant

4.1. Properly Kept Commercial Books Constitute Strong Evidence in Favor of a Merchant

According to our system of legal procedure, commercial ledgers that have been properly kept and contain records relating to the transaction in dispute between the parties evidence in favor . In particular:

In debt collection cases,
In current account disputes,
In disputes arising from contracts for the delivery of goods, provision of services, commission, agency, and dealership agreements,
In the creditor-debtor relationships of company partners

Commercial ledger entries often play a crucial role in proving the existence, amount, and date of a receivable.

For example, a wholesale trader might be unable to obtain a dealer's signature on most of the invoices for goods sold, or a dispute might have arisen. However, if these sales are recorded regularly and consistently in the journal, general ledger, and inventory accounts, and this is also supported by bank account statements, then these ledgers become important evidence for proving the trader's receivables

4.2. Specific Conditions Required for Evidence to be Constituted in Favor of the Defendant

In order for a merchant to use their commercial books as evidence in their favor, certain additional conditions must be met in addition to the general requirements:

The ledgers should be organized and corroborate each other:
- The entries in the daily journal must be consistent with the entries in the general ledger and the inventory ledger.
The ledgers must have been certified as closed
- It is not enough to simply have the opening confirmation done; ledgers without closing confirmation may have weakened evidentiary value.
The parties to the dispute must be merchants (as a rule):
- If both parties are merchants and the transaction is commercial in nature, the books are examined "mutually"; consistent records constitute evidence in favor of the claimant.
The other party's records must have been presented and there must be no contradictions between them:
- If both parties' business books contain consistent records regarding the transaction in dispute, these records are substantially binding on the judge.

4.3. The Court's Method of Examining the Records

The court usually does not examine commercial ledgers directly; it sends them to an expert. The expert determines whether the ledgers were kept properly, whether the records corroborate each other, and the status of the records related to the transaction in dispute. The expert report plays a decisive role in the judge's decision.

For example, in a current account receivable case, if the merchant's journal and general ledger records clearly show the dealer's outstanding balance, and these records are supported by bank statements and delivery notes, the court generally tends to accept the merchant's claim as proven.

5. The Evidential Value of Commercial Books Against a Merchant

Commercial ledgers are accepted as evidence not only in favor of the merchant, but also, in some cases, against them . The basic logic here is that the merchant kept the ledgers himself and created the records of his own free will . Therefore, the entries in the ledger can be considered as an indication that the merchant acknowledged certain facts.

5.1. The Merchant's Books of Account as Evidence in Favor of the Opposing Party

In the following situations, business ledgers can have adverse consequences for a merchant:

a merchant's books contain an entry for debt , and this entry is properly maintained, it can be significant evidence that the merchant is indebted.
If the merchant cannot refute this entry, which is against him, error, fraud, forgery, or accounting error , the court will consider the entry as evidence against him.
Even if the opposing party is not a merchant, the entries in a merchant's commercial ledgers can constitute evidence in favor of the opposing party under certain conditions. In this case, the court may treat the ledgers as "a statement amounting to an admission."

For example, if a merchant has a clear record in their books indicating that a debt owed by a customer to whom they delivered goods has been settled – for instance, if the accounting entry states, "Customer X's debt has been settled" – it becomes very difficult for them to later claim that the debt still exists. This is because the record in their books is considered strong evidence against them.

5.2. Adverse Consequences of Refusing to Present Ledgers

Another important area where commercial ledgers can have adverse consequences the ledgers are not presented . According to the Code of Civil Procedure:

The court may order one of the parties to submit their business records.
If a merchant refuses to present his books without a justifiable reason, other than "trade secrets that should remain confidential" or other reasonable grounds, this will be assessed against him.
In cases where a merchant refuses to present the books without justifiable cause, the opposing party's claims and other evidence may be considered stronger; indeed, in some cases, the contents of the books may be presumed to have been kept in accordance with the opposing party's claims.

For example, in a debt collection case, the court requests an examination of the debtor merchant's books, orders their submission, but the merchant fails to do so without any reasonable justification. In this situation, the court might conclude that "if the books had been submitted, they would have demonstrated the existence of the debt," and this could have serious evidentiary consequences against the merchant.

6. Evidential Value of Commercial Books Depending on Whether the Parties Are Merchants or Not

When evaluating the evidentiary value of commercial ledgers, whether the parties to the dispute are merchants or not is important. In general, three scenarios emerge:

6.1. Cases Where Both Parties Are Merchants

If both parties to the dispute are merchants and the dispute arises from a commercial transaction, the commercial books of both parties are examined.
both ledgers are properly prepared and the records are consistent , these records constitute strong evidence.
If there are discrepancies between the records, the court will consider this inconsistency along with other evidence; sometimes it may deem one of the ledgers less reliable due to irregularities or inconsistencies.

6.2. Cases Where Only One Party Is a Merchant

If only one of the parties is a merchant, the non-merchant party has no obligation to keep commercial books.
In this situation, the merchant's books often have a stronger influence against the merchant. Where the merchant's own books contain entries that are detrimental to them, the court will take those entries into consideration
Records favorable to the merchant may not be binding on their own; the court may consider them discretionary evidence and weigh them against other evidence.

6.3. Cases Where Neither Party is a Merchant

If neither party is a merchant, it's impossible to even speak of a commercial ledger.
In this case, other evidence in the file, such as documents, contracts, bank records, and correspondence, takes precedence.

7. The Relationship of Commercial Books to Other Evidence and the Judge's Discretion

Commercial ledgers are often not considered in isolation; invoices, delivery notes, contracts, bank statements, email correspondence, SMS records, and witness statements . The court:

Whether the entries in the commercial ledgers are consistent with these documents ,
Whether the record relating to the transaction in question was kept systematically and regularly ,
The records' conformity to the ordinary course of life.

He examines it carefully.

Judges generally regard commercial ledgers not as conclusive evidence , but as discretionary evidence . That is, the entries in the ledgers are evaluated in conjunction with other evidence to reach a conclusion. However, commercial ledgers that fully meet the requirements and are deemed complete and reliable can, in practice, constitute very strong evidence.

8. Evidential Consequences of Irregular or Complete Absence of Commercial Bookkeeping

Violation of the obligation to keep commercial records not only results in tax and administrative penalties; it also seriously weakens the evidentiary value of the business.

8.1. Consequences of Improper Bookkeeping

Improper keeping of accounting records; for example:

Failure to obtain opening or closing certifications on time,
The records do not reflect the truth,
The records may contain discontinuities, sorting errors, deletions, erasures, or blank pages
Having conflicting entries in different ledgers regarding the same transaction

In such cases, the court views these ledgers with suspicion and diminishes their evidentiary value.

A merchant often finds it difficult to prove his claim based solely on these ledgers; he frequently has to support his arguments with other evidence . In some disputes, the ledgers may be disregarded altogether.

8.2. Consequences of Not Keeping Records or Failure to Present Them

no records are kept, or if the records are lost, damaged, or no certificate of loss has been obtained :

A merchant cannot use his books to his advantage.
Its probative value weakens, and it often in a weak position .
The court may interpret this situation against the trader; the case may be lost, especially if no other evidence consistent with the claims is presented.

If the ledgers are claimed to be lost, the merchant a certificate of loss . Otherwise, the statement "the ledgers are lost" alone will not be accepted.

9. Electronic Commercial Ledgers (e-Ledgers) and Their Evidential Value

Many businesses today e-ledgers and e-invoices . In Turkish law, commercial ledgers kept electronically the same legal value as paper ledgers .

The following points should be considered regarding the evidentiary value of electronic ledgers:

The e-ledger must be kept in a format compliant with the relevant legislation and stored in a way that is protected against the statute of limitations.
The immutability and reliability of ledgers should be ensured by using tools such as electronic signatures and digital seals .
During the trial, the e-ledgers are submitted electronically to the expert witness , and if necessary, printouts are taken and added to the file.

Electronic ledgers that meet the necessary technical requirements, are organized, and accurately reflect the truth, carry the same evidentiary weight in court as traditional paper ledgers. In fact, due to their time stamping and immutability features, they are often considered more reliable.

10. Common Scenarios in Practice and the Role of Commercial Ledgers

10.1. Receivables Disputes Between Supplier and Buyer

In a dispute between a wholesaler and a dealer, in response to the dealer's defenses such as "I did not receive this quantity of goods" or "The amount owed is not this much," the wholesaler's commercial ledgers show:

Regular sales records,
Current account balances,
Bank collection records

If these documents exist and are supported by invoices and delivery notes, strong evidence in favor of the merchant .

10.2. Current Account and Partnership Receivables

In partnerships or long-term commercial relationships, the current account is a crucial institution. Parties conduct transactions spanning months or years through the current account. Current account entries in commercial ledgers:

On what date the account was in debt/with a balance?
Whose favor the balance is in?
Which processes are they related to?

This reveals the situation. Therefore, in current account cases, commercial ledgers often determine the outcome of the case.

10.3. Commission Disputes in Commission, Agency and Dealership Agreements

In cases where an agent or distributor claims that commissions received have been underpaid, records of commission payments are sometimes only found in the client's books. If the merchant's books contain records indicating that commission payments were made in full, the agent's claim is weakened. Conversely, if the books contain records showing full commission payments, they may constitute indirect evidence in favor of the agent.

11. Practical Tips for Business Owners: View Your Business Books as Evidence

Considering the evidentiary value of commercial ledgers in court, merchants and companies need to shift their bookkeeping practices from a "merely fulfilling tax obligations" perspective to one of " strategic evidence management in the judicial process ." In this context:

Make sure you keep your notebooks properly.
- Get your opening and closing certifications done on time.
- Avoid actions such as erasing, scratching, or leaving blank pages.
- Enter your records close to the date the transaction occurred; entering records from a distance weakens their probative value.

- Invoices, delivery notes, contracts, bank statements, and correspondence should support the records in the ledger.
- This way, in case of a dispute, you will have supporting evidence in addition to the business ledgers.
Keep your ledgers and electronic records secure.
- Take precautions against risks such as fire and flooding in physical ledgers.
- Implement backup and cybersecurity measures for e-ledgers and digital records.
- In cases of loss or damage , apply for a certificate of loss immediately
Seek professional legal assistance regarding the submission of accounting records.
- When a court requests the submission of accounting records, work with your lawyer to protect trade secrets and ensure only the portions relevant to the dispute are submitted.
- Remember that failing to present your ledger without a valid reason will have negative consequences for you.
Conduct regular internal audits and accounting checks.
- Especially in large-scale businesses, working with internal audit units or independent audit firms ensures that your records are sound, both for tax purposes and as evidence.
