Housesitting runs on trust, and trust often works. Plenty of people never need anything in writing. The trouble is that you can’t tell in advance which sit will be the one that goes wrong.
If you’re asking this question, something has probably prompted it. Maybe a friend had a bad experience. Maybe you read a forum thread that made you nervous. Maybe you’re about to do your first sit with someone you’ve only met on a video call, and it feels like a lot of trust for a screen conversation.
Here’s the honest answer: you don’t need a contract. You can do every housesit on a handshake and probably be fine. But “probably fine” isn’t the same as “protected.” And understanding the difference is what this article is about.
What happens when there’s no agreement
Nothing — until something goes wrong. Then everything happens at once, and none of it is documented.
Without a written agreement, every one of these questions is unanswered:
The vet says it’ll be a large bill
Who authorised the treatment? What was the spending limit? Who pays upfront? You never discussed it — because why would you, everything was going to be fine.
The sitter finds indoor cameras nobody mentioned
Were they disclosed? You can’t prove either way. The homeowner says they mentioned it. The sitter says they didn’t. No record. No resolution.
The homeowner returns to a house that doesn’t meet their standards
What was “clean”? What was the departure standard? Without a shared definition, it’s just two people with different expectations and no way to determine who’s right.
The sitter cancels three days before the sit
Was it called off too late? Does the reason matter? Who covers last-minute kennels? Without anything agreed, it’s hard to say who should bear the cost.
Two honest people can leave the same video call remembering it differently. Good intentions aren’t a record. And when something goes wrong, there’s often nobody else to sort it out but the two of you.
When a handshake isn’t enough
Some arrangements are genuinely low-risk. A weekend flat-sit for a friend with one cat, where you’ve done it three times before? A handshake is probably fine. But the risk profile changes fast as complexity increases.
A written agreement becomes essential when any of these are true:
The sit is longer than two weeks
Longer sits have more time for things to go wrong, more opportunities for expectations to drift, and more financial exposure on both sides if someone cancels.
Pets have health issues or complex needs
Medication schedules, dietary restrictions, reactive behaviour, elderly animals approaching end of life — these need documented protocols, not verbal assurances.
You’ve never met in person
A video call builds rapport. It doesn’t build accountability. When the only connection is digital, a signed document makes commitments much clearer.
Money is involved
Payment raises the stakes on both sides. A spoken agreement can still count in law; the trouble is proving what was said. Writing it down settles that before it matters.
The property has specific requirements
Pools, gardens, specialist equipment, alarm systems, multiple access points. The more complex the property, the more that needs documenting.
Even for simple sits, there’s a pragmatic argument: the act of making an agreement surfaces things you’d otherwise discover mid-sit. You might think you agree on cleaning standards until someone asks you to define them. You might assume the sitter knows the heating is off-limits until they turn it up to 24°C on a January evening. The conversation matters as much as the document.
What an agreement actually does for you
A housesitting agreement isn’t a legal threat. It’s a shared record of what two people decided together. Its value isn’t in court — few disagreements need to go that far. Its value is in preventing the argument from starting.
It replaces memory with a record
Three months from now, neither of you will remember exactly what was said on that video call. A signed document doesn’t drift. It says what it said on the day you both agreed.
It forces the awkward conversations early
It’s awkward to ask about vet spending limits on a friendly video call. It’s awkward to raise cameras, or cleaning standards, or what happens if someone cancels. An agreement process asks these questions for you — so you don’t have to be the one who makes it uncomfortable.
It gives you something to point to when things go wrong
“Here’s the agreed vet limit, in writing” is a fact. “I think we said something about a vet limit” is a memory. If you ever need to resolve a dispute, the first sentence ends the argument. The second one starts it.
Why it doesn’t have to be a chore
It often isn’t that people think an agreement is a bad idea. It can just feel like too much work for something that’s supposed to be based on trust. Download a PDF template, read through twelve sections of legalese, fill in the blanks, email it to the other person, wait for them to read it, negotiate the bits they don’t agree with, sign it, store it somewhere you can find it again. That’s a lot to ask for a two-week housesit.
Reputable Sitters works differently. You start with eight questions that tend to cause trouble (cameras indoors, the urgent vet decision, the last morning and five more), and the agreement writes itself from your answers.
Then you send it to the other person, who answers from their side. Where you differ, you see it straight away, and either of you can move. Not twelve sections of legalese: eight questions, the basic facts, and a signature each.
And if something does go wrong, the signed agreement is what you both go back to. We don’t decide who’s right and we never hold money. You can each download the agreement, and either of you can download your own record of changes, with the signatures; beyond talking it through, it’s between you and, if it ever came to it, the courts.
A last-minute kennel booking, an emergency vet bill with no agreed limit, a cleaning row that turns into retaliatory reviews: the question isn’t whether you can afford an agreement. It’s whether you can afford not to have one, the one time it matters.
So do you need a contract for housesitting? No. You need one for the housesit that goes wrong. And you won’t know which one that is until it’s too late to write it.
