Most shared vacation homes run on an unwritten understanding. It works for a while, usually as long as the person who set it up is still the one running it. Then a sibling marries, a cousin stops paying, someone wants to rent the place out, and the understanding turns out to mean different things to different people.
A written agreement is the fix. It does not have to be long or formal to be useful. It just has to answer the questions that come up, in writing, before they come up. Here is what families put in one, and a simple outline you can adapt.
This is general guidance, not legal advice. Ownership, title, and tax questions depend on your state and how the property is held. Have an attorney review anything that touches those.
Why write it down at all
An agreement is not a sign of distrust. It is a way to keep small questions small. When the rule for holiday weeks is written down, nobody has to relitigate Thanksgiving every October. When the reserve fund contribution is written down, the sibling who fronts the new well pump does not have to chase everyone for their share.
Written rules also outlive the person who made them. That matters more than it seems, because the family member who quietly ran the place for thirty years is exactly the person whose knowledge disappears when they step back.
The outline
Use these sections as headings. Fill in what fits your family and cut what does not.
1. Who is in
List the owners or member families and, if it applies, how ownership is split. Note who counts as immediate family for booking purposes: spouses, kids, grandkids. Decide now whether a partner who is not married in gets the same standing as a spouse.
2. How time is shared
This is the section most families need most. Cover:
- How weeks are claimed. First come first served, a rotation, a draft each spring, or a mix. Our guide to fair booking rules for a shared cabin walks through the common systems.
- Holidays and prime weeks. Rotate them, or draft them first, so the same branch does not get the Fourth of July every year.
- How far ahead people can book. A booking window keeps one family from claiming the whole summer in January.
- Limits. A maximum number of nights per family per season, if usage is uneven.
- Where the calendar lives. One shared calendar everyone can see. Not a group text.
3. Money
Spell out who pays what and when:
- Fixed costs: property tax, insurance, mortgage if there is one, HOA or road association dues.
- Utilities: electric, propane, internet, water, trash.
- Routine upkeep: lawn, dock in and out, septic pumping, chimney sweep.
- A reserve fund for big items, with a set contribution per family per year.
- Whether costs are split evenly or by usage, and how usage is counted.
Name one person as treasurer for a set term, and give everyone access to the running ledger. Our guide on splitting the costs of a shared vacation home goes deeper.
4. How decisions get made
Sort decisions into three tiers and say who decides each:
- Anyone can do it: book a week, restock the pantry, buy a replacement coffee maker under a set dollar amount.
- A majority decides: a new house rule, a repair over that amount, a change to the booking system.
- Everyone must agree: selling, refinancing, a major renovation, admitting a new owner.
Write down the dollar thresholds. Vague words like “major” cause arguments; numbers do not.
5. Upkeep and house rules
Say who is responsible for what between visits and at season changes. Attach the opening and closing checklists, or point to where they live. Attach the house rules too: pets, guests, smoking, quiet hours, what “leave it how you found it” actually means. See house rules for a family vacation home for examples.
6. Guests and renting
Decide whether members can host friends without a family member present, whether the place may ever be rented to strangers, and who gets the income if it is. Families split hard on renting. Better to settle it in writing than to discover the split during a booking.
7. Leaving, dying, and selling
Nobody enjoys this section and everybody needs it:
- Can an owner sell their share? To whom? Do the others get first refusal, and at what price or formula?
- What happens to a share when an owner dies? Does it pass to their kids, and do those kids get a vote?
- What if someone stops paying? A grace period, then what?
- What would it take to sell the whole place?
An attorney should draft the parts that touch ownership. The family’s job is to agree on the intent first.
8. Changing the agreement
Say how the agreement itself gets amended, usually by the same vote as the biggest decisions, and set a date to review it every few years.
Keep it where people will find it
An agreement in one sibling’s filing cabinet is nearly as useless as no agreement. Keep it with the house, digitally, next to the calendar, the checklists, and the house rules. That is the idea behind SharedStead: one private place where the rules, the schedule, and the family all live together, so the next generation inherits the system and not just the house.
If you are starting from nothing, do not try to write the whole thing in one sitting. Agree on the calendar and the money first. Those two sections prevent most of the arguments. The rest can come over the winter.
