Neighbor fence cost-sharing
Boundary fences are usually shared — the cost just needs to be too. Print an agreement, open the conversation well, and know the paths when you disagree.
How it usually works
Many US states have boundary — “partition” — fence statutes. Some set a default split (often 50/50 for a fence on the property line), and several provide a fence viewer process when neighbors disagree (Iowa, Indiana, Michigan and Kansas, for example). Your state's statute and your HOA covenants decide, so check both first — this page is a template, not legal advice.
Cost-sharing agreement
Fill it in together, sign two copies, one each. Five minutes of writing prevents most of the disputes that reach a fence viewer.
This agreement is made between (“Owner A”) and (“Owner B”) for the boundary fence between and .
1. Scope
- Length ft · Height ft
- Material and style (e.g., 6 ft cedar privacy):
- Posts, footings and removal of any old fence: included
- Gate (number and position):
2. Cost and split
- Written quote total: $ (quotes attached: )
- Owner A share % · Owner B share % (50/50 unless agreed otherwise)
3. Payment and timing
- Each owner pays their share within days of completion, against the invoice or receipts.
- Target start: . Neither owner changes scope or material without the other's written agreement.
4. The fence stays with the land
The fence and this agreement are intended to run with the properties. In some states a written fence agreement can be recorded so future owners are bound — verify locally.

Opening the conversation
- Lead with what you both get — privacy, pets in, a better view — not with money.
- Bring the quote in writing. Numbers stop arguments; adjectives start them.
- Offer 50/50 on a fence on the line; if the fence is mostly for one side, say so and propose that split instead.
- Write it down even when it's friendly. A text that says “yes — 50/50 on the $4,200 quote” is already evidence.
- Agree before materials are ordered — never after.
If you disagree
- Check your state's partition-fence statute: some states let one owner build and bill the neighbor for half; defaults differ state to state.
- Fence viewers (several states, e.g., Iowa, Indiana, Michigan, Kansas): the county inspects and assigns each owner's share.
- Mediation first if the relationship matters; small claims for a billed share within your state's limit.
- HOA covenants can be stricter than the statute — read them before digging.
