Debts and Who Can Prove Them
Liabilities reduce what somebody has, which makes them worth proving and worth doubting. Debts owed to banks document themselves; debts owed to relatives are asserted in a sentence and are considerably harder to establish.

The rule in short
A debt to an institution is evidenced by statements, agreements and payment history, and proves itself easily. Informal debts between individuals require the same material as any other private arrangement: a contemporaneous record, a repayment history, and consistency with how the parties treated the money before the question arose. Debts asserted for the first time when they become useful attract scrutiny.
Debts appear in files for two opposite reasons: to show that somebody owes money, which reduces their means, and to dispute that they owe it. Both directions run into the same question about what actually evidences an obligation.
Institutional debts
Statements do most of the work. A lender issues periodic statements showing the balance, the payments made and the terms, all generated independently of any proceeding.
The agreement establishes the terms. Interest, duration and the payment obligation come from the credit agreement rather than from the current balance.
Payment history matters. Whether payments have been made on time bears on whether the obligation is real and on what it costs each month.
Redemption figures. For a loan being settled, a formal figure from the lender is the current position and is worth obtaining directly.
Credit reports summarize. A report lists obligations across lenders, which is useful as a map and is not a substitute for the underlying documents.
Secured against unsecured. Whether a debt is secured on an asset affects both the risk and what the asset is worth to its owner.
Foreign lenders. Statements from institutions abroad need translation and the ordinary authentication treatment before they can be relied on.
Arrears and default notices. Correspondence about missed payments establishes both the obligation and its current state, and it arrives without anybody requesting it.
Informal and family debts
The gift or loan question again. Whether money from a relative created an obligation is decided the same way as anywhere else, per gifts, loans and the difference.
A contemporaneous note settles it. Anything written when the money moved is worth more than the most detailed later account of what was agreed.
Repayments are the best evidence. Regular payments to the lender, visible in bank records at both ends, establish the obligation more convincingly than any document.
Demands made at the time. Correspondence chasing repayment, sent before any proceeding, is contemporaneous evidence that a debt was understood to exist.
How it appeared elsewhere. Whether the debt was disclosed in earlier applications, accounts or filings shows how it was treated before it became useful.
Late assertion is weak. A liability mentioned for the first time at the point where it reduces available means is assessed with that timing very much in mind.
The lender should confirm it. A statement from the person owed, describing the loan and the balance, is the minimum where no contemporaneous document exists.
| Debt type | Proved by | Difficulty |
|---|---|---|
| Bank loan or mortgage | Statements and agreement | Low |
| Credit card | Statements | Low |
| Judgment debt | The order plus payments | Low |
| Family loan | Contemporaneous note, repayments | High |
| Guarantee | The guarantee document | Contingent, not present |
Contingent and disputed liabilities
A guarantee is not a present debt. Standing behind somebody else's obligation is a liability that crystallizes only if they default, and it is treated differently.
Disputed claims. Where a debt is contested, the claim exists and the obligation may not, and both facts belong in the file.
Pending proceedings. A claim not yet determined is a possible liability, and describing it as an established one overstates the position.
Tax assessments under appeal. These sit between certain and contingent, and the documents showing the assessment and the appeal are both relevant.
Judgments. A determined liability with an order behind it is at the strong end, and the order plus any payment record establishes it.
Statute-barred debts. Obligations too old to be enforced may still be owed in a moral sense, and they are frequently not liabilities for these purposes at all.
Debts under a payment arrangement. Where a creditor has agreed reduced payments, the arrangement rather than the original terms determines the current obligation.
Requirements ask for one or the other and files supply whichever was easier to find. A debt of a large amount repaid at a small monthly figure affects available means very differently from a small debt repayable immediately, and a schedule showing both answers either question.
What a requirement actually asks
Balance or monthly obligation. Some requirements care about total indebtedness and others about what has to be paid each month, and the answers differ enormously.
Household or individual. Where a household position is in issue, a partner's debts may be relevant and their absence noticed.
Secured debts against assets. A mortgage matters mainly as a reduction in the value of the property, per valuing property for a proceeding.
Debts owed to the person. Money somebody is owed is an asset rather than a liability, and its collectability is a separate question.
Disclosure obligations. Where all liabilities must be listed, an omitted one is a disclosure problem regardless of its size, per undisclosed assets and how they surface.
Read before assembling. The scope of the question determines which documents matter, and gathering everything is slower and less useful than gathering the right things.
Presenting liabilities
Schedule them. A single table listing each debt, the creditor, the balance, the monthly payment and the supporting document is the useful format.
Attach a document to each line. A liability listed without evidence is an assertion, and the schedule is only as good as what sits behind it.
Give the payment obligation as well as the balance. Most requirements about means care about the monthly cost rather than the total outstanding.
Show the payment history. Records of payments being made establish that the obligation is real and being serviced.
Explain informal debts fully. Where a family debt is asserted, the origin, the terms and any repayments should all be set out rather than summarized.
Do not omit the awkward ones. A liability left out because it is embarrassing is far worse when it emerges than it would have been if disclosed.
Update before filing. Balances move constantly, and a schedule built on figures six months old invites a request for current ones.
Show the creditor clearly. A liability described only by amount, without identifying who is owed it, cannot be checked and is treated accordingly.
Debts split cleanly into two kinds. Obligations to institutions document themselves through statements and agreements, and obligations between individuals require the same proof as any other private arrangement.
For informal debts, contemporaneous records and repayment history are what establish them. A liability asserted for the first time when it becomes useful is assessed with that timing firmly in view.
Contingent and disputed liabilities occupy their own category. A guarantee is not a present debt, a contested claim may not be an obligation at all, and describing either as established overstates the position.
What a requirement actually asks determines which documents matter: total indebtedness, monthly obligations, household position or full disclosure are four different questions with four different answers.
The presentation that works is a schedule with a document behind every line, showing both balance and monthly payment, supported by payment history, and containing the awkward entries as well as the convenient ones.
Points to carry away
- Institutional debts prove themselves through ordinary records.
- Informal debts need contemporaneous documents or repayments.
- A debt asserted only when useful carries very little.
- Contingent and disputed liabilities are treated differently.
- Both the balance and the payment obligation matter.
Questions readers ask
How is a debt to a family member proved?
The same way any informal financial arrangement is: with a contemporaneous record and a repayment history. A dated note written when the money moved settles it immediately. Absent that, regular payments back to the lender, visible in bank records at both ends, are the strongest available evidence. Correspondence chasing repayment before any proceeding began also helps, as does evidence that the debt was disclosed in earlier applications or accounts. An assertion made for the first time when the liability becomes useful carries very little.
Is a guarantee a debt?
Not a present one. Standing behind somebody else's obligation creates a liability that crystallizes only if that person defaults, so it sits in the contingent category rather than among current debts. It is still worth disclosing where a requirement asks about liabilities generally, described accurately as a guarantee with the underlying obligation identified. Presenting it as an established debt overstates the position, and the overstatement is easy to detect from the document itself.
What is the most common mistake in presenting liabilities?
Giving the outstanding balance without the monthly payment obligation, or the reverse. Requirements about available means are usually interested in what has to be paid each period, while requirements about net position are interested in the total. A schedule listing each debt with the creditor, the balance, the monthly payment and the supporting document answers either question. The second most common mistake is omitting a liability that is embarrassing, which is considerably worse when it emerges later.

More in Proving Money
Proving the Source of Funds
A source of funds inquiry asks how money came into existence rather than which account it last sat in. The answer requires evidence of the generating event, a documented path from there to the present holding, and consistency with everything else known about the person's finances. How far back the inquiry runs is set by the requirement rather than by preference.
Bank Statements and Their Gaps
Bank statements are persuasive because an institution produced them and because they are internally checkable. Their weakness is that they are supplied selectively. Missing pages, accounts that appear once and vanish, balances that do not carry forward and unexplained large movements are the features a reader notices before anything else in the file.
Undisclosed Assets, and How They Surface
Undisclosed assets are usually revealed by inconsistency rather than by searching. Transfers to accounts that appear nowhere else, spending that exceeds declared income, insurance and tax records filed for other purposes, and public registers all expose holdings. The consequences of non-disclosure are typically worse than the consequences of the asset itself.
