Evidence package before a dispute

Practicum for Volume 3, Chapters 6 and 10. Version: 2026-07. Time: 20 minutes for one situation. A worksheet for money, work, transactions, and reputation. It does not replace advice from a qualified professional.

Build verifiability before a conflict begins. Choose one situation where an error would be expensive. Connect four layers in advance: what happened, source material, context, and an independent record.

1. Describe the future dispute in one sentence

If a dispute begins, I will need to confirm that _________________________________

Do not write, "I am right." Write a fact someone can check: an instruction was given, a result was approved, an item had a certain condition when transferred, or a publication existed on a certain date.

2. Gather four layers

Layer	What belongs in the package	What I have
Event	date, participants, action, amount, or subject
Source	original file, email, contract, photo, or recording
Context	messages before and after, document version, call record
Independent record	statement, system log, email header, or confirmation from another person

If you fill only the source row, the package is weak. A polished file does not explain where it came from or what happened around it.

3. Choose your situation

Money

contract, invoice, and original payment details;
separate confirmation of a change in recipient or amount;
payment order, receipt, and statement;
bank case number and the time you reported the incident;
company approval log, if one exists.

Rule for the future: Confirm new payment details and urgent payments through an independent channel.

Work

written employment or project terms;
task description and definition of done;
versions of the result and comments on them;
email or system record of approval;
log of the delivery and later changes.

Rule for the future: Turn an important spoken promise into a short same-day email: "Have I understood this correctly?"

Transaction

contract and attachments;
photos or video of the item's condition before transfer;
serial number, included parts, and meter readings;
transfer document, receipt, and shipping record;
confirmation from the other party or an independent participant.

Rule for the future: Record the condition before the item or access changes hands.

Reputation

original post or message;
full page address and date;
screenshot with the surrounding page, not only a cropped sentence;
archived copy, platform notice, email, or another person's screenshot;
log of reports to the platform and its responses.

Rule for the future: Record the content, account, address, time, and platform response.

4. Check independence

Ask four questions about each item:

Is it stored only with me?
Could someone change it without leaving a trace?
Which person or system can confirm it independently?
Will that record still exist in a month?

Weakest layer in the package: _________________________________________________

One move today: ________________________________________________________

5. How much is enough for a video, a hire, or a payment?

A formal dispute is the extreme case. You usually need to answer a smaller question: How much verification is enough for this decision? The answer depends on the cost of being wrong, not on how strange the item looks.

What a credential really confirms

Credential or evidence	What it confirms	What it does not confirm
Diploma or certificate	the person completed a program at a stated time	that they can do the work today
Platform review	someone posted positive words	that the author exists or had the claimed experience
Case study or portfolio	a result is shown	that this person produced it
Product demo	the system works on prepared data	that it will work on your data
Named recommendation	the author is willing to put their reputation behind the statement	that they examined the work closely
Independent audit or measurement	a third party checked something with a stated method	that the method fits your situation
Signed file or provenance record	origin and change history	that the content is true

How much to check at different levels of risk

Decision	What you lose if you are wrong	Enough verification
Watch or forward something funny	nothing	none; save your attention
Cite something publicly as fact	your reputation	primary source and date
Hire someone	months of work and access	live conversation, work artifacts, and one independent person who will stand behind the reference
Pay or change payment details	money, often with no way back	confirmation through a channel known in advance; for a large amount, add a second signer or limit
Share data or access	the change may be irreversible and may affect other people	all of the above, plus a written basis and an expiration date

Record the result as one of three states: confirmed, probable, or unknown. Apply the state to this decision, not forever. Strong verification does not pretend to settle everything. It makes the remaining uncertainty visible.

Turn the table toward yourself. Which claims about you can survive these questions? Which parts of your portfolio or proposal still depend on "take my word for it"? Continue with the Trust footprint map.

What looks like evidence but often is not

a screenshot without an address, date, or context;
a forwarded video instead of the original;
an "enhanced" recording with no preserved original;
a clearly named file with no history of how it appeared;
your own log with no link to another system;
a spoken agreement that everyone remembers differently.
