The strongest evidence in almost any consumer dispute is something written down before anyone knew there would be a dispute. A text message sent the afternoon of the delivery, a photograph taken because the damage was annoying rather than because it was going to be argued about, a note on a calendar. Those hold up. A detailed account written six months later, however accurate, does not carry the same weight, because everybody knows what it was written for.
That is the whole principle, and most of what follows is a consequence of it.
Contemporaneous beats thorough
Anyone reviewing a dispute, whether that is a manager, an insurer, a mediator, or a small claims judge, is weighing two accounts against each other. What tips it is a record that was created at the time and has no obvious purpose beyond recording what happened.
This is likely to matter more than people expect and it is easy to arrange in advance. When something goes wrong, send yourself an email that day describing it in three sentences. Not a formal statement. Time, what happened, who said what. Email carries a timestamp that is difficult to argue with, and the fact that you wrote it before the argument existed is exactly what gives it weight.
What a photograph proves
Less than most people think, and enough to matter. A photograph reliably proves that a condition existed when the photograph was taken. It does not prove when that was, unless the file still carries its original data, and it does not prove what caused the condition.
Three habits make photographs much more useful. Take a wide shot before the close one, so the damage can be located in a room or on a building rather than floating in a frame with no context. Put something of known size in the frame, a tape measure or a coin, because scale is the first thing lost. And photograph the undamaged parts too, since a claim that a whole floor was ruined is undermined by the fact that only one photograph exists.
Keep the originals off the phone. Photographs that live only in a camera roll get compressed by messaging apps, lose their data, and disappear with the phone.
The records you already have
Most people have more than they realize and go looking for it too late.
- The estimate or work order, particularly if it lists what was included.
- Bank and card statements, which establish dates and amounts that nobody can dispute.
- Text threads with the contractor, the landlord, or the seller. These are frequently the entire case.
- Delivery and tracking confirmations.
- The original listing or advertisement, which is worth saving as a screenshot because listings get edited.
Pull all of it into one folder in the first week. Records that are theoretically retrievable have a way of becoming genuinely unavailable when a company changes systems or an account closes.
The three weak kinds
Recollection is the first. Honest, and unpersuasive on its own, because the other party has one too and theirs is different.
Second is what somebody else told you. An account of what the previous tenant said, or what a neighbor heard, is generally given very little weight unless that person is willing to say it themselves in writing. Worth asking them early, while they still remember and still care.
Third is an opinion from someone with no standing. A friend in the trade saying the work is substandard is not the same as a written assessment from a licensed inspector or a competing contractor who examined it and put their name on the page. The second one costs money and is occasionally the only thing that moves a dispute.
Keeping it so it survives
A dispute that goes the distance can run a year or more, and files get lost in that time. One folder, backed up somewhere that is not the phone. A single page at the front listing what happened and when, in date order, updated as things occur.
That timeline page does more work than any individual document. It is the thing you hand to an attorney, quote from in a complaint letter, and read from if you end up in front of somebody. Having it means the story is the same every time you tell it, which is itself a form of evidence.
None of this requires expecting the worst of people. It requires ten minutes on the day, which is a small price for being the party who can show what happened.
