# Boundary Disputes With a Neighbour: From Re-Measuring to Mediation

Vorneo Property · [Legal & Documents](https://vorneo.id/en/artikel/topik/legalitas/) · 2026-10-25

Boundary disputes rarely start with a big row. They creep up: a neighbour builds a new fence, their roof gutter hangs over, old markers vanish under landfill, or a survey before a sale shows something different from what everyone assumed.

Left alone, a small problem like this can hold up a sale, a KPR (Kredit Pemilikan Rumah, a home loan) application or the splitting of a certificate. Handled in a rush, it wrecks the relationship next door. This guide sets out a sensible order of steps, starting with the lightest.

## Common causes

Typical reasons for a boundary dispute:

- **Markers lost or moved.** On swamp and peat land, as around Banjarmasin, wooden markers can rot, sink or get buried under fill.
- **Fences built without a survey.** The builder follows a guess, not the official boundary points.
- **Old documents.** Land that once had only a segel or a local land statement often came with estimated measurements.
- **Area differences.** The area on the ground doesn't match the certificate. Our guide on [measuring land area](/en/artikel/mengukur-luas-tanah/) explains why.
- **Overhanging structures.** Eaves, gutters or steps that cross the line.

## Step 1: gather your documents

Before talking to your neighbour, make sure you know the recorded boundary. Have ready:

- The original certificate, including its survey map (surat ukur or gambar situasi).
- The AJB (Akta Jual Beli, the deed of sale) or other proof of how you acquired it.
- Older papers if there are any, such as a segel or SKT (Surat Keterangan Tanah, a land statement letter).
- Old photos showing where the markers or fence used to be.

Also check the certificate data at the land office or through the official services of BPN (Badan Pertanahan Nasional, the national land agency). Our guide on [how to check a land certificate](/en/artikel/cara-cek-sertifikat-tanah/) walks through it.

## Step 2: talk it over first

Many boundary disputes get settled on the front porch. Visit your neighbour, show the documents and suggest finding out together. Don't accuse. Quite often the neighbour has no idea their fence is off.

Pick a calm moment, not while the neighbour's builders are on site or tempers are running high. If things are already tense, ask the RT head to sit in from the start as a go-between.

If you both agree the line needs confirming, apply for an official survey together. You can split the cost, and the result is easier for both sides to accept.

## Step 3: ask BPN to re-mark the boundary

The land office offers a service called pengembalian batas (boundary re-establishment). A surveyor comes to the site, measures from the survey map data, and shows or reinstalls the boundary markers.

Things to know:

- The owner or their representative applies, with the certificate and ID.
- There's an official fee. Ask at the land office counter how much it is.
- Neighbours who share the boundary are usually asked to attend the measurement to point out and agree to the line. Their presence matters, so the result is accepted.
- The result goes into an official record (berita acara). Keep a copy.

If the neighbour's land has no certificate, the measurement still works from the registered data. Involve the RT (the neighbourhood head) and the kelurahan or village office, since they often know the history of land in their area.

## Step 4: mediation

If the result isn't accepted, or the neighbour won't move the fence, mediation comes next. There are a few places for it:

- **The RT, kelurahan or village office.** Good for small differences and relationships still worth keeping. Write the agreement down and have both sides and witnesses sign it.
- **The land office.** It handles land complaints and can host mediation, especially when the problem touches certificate data.

Good mediation ends with something concrete: the fence moves back by a set distance, or the neighbour whose building already crosses the line buys that small strip. If the boundary or area changes, update the records at the land office through a PPAT (Pejabat Pembuat Akta Tanah, the official who draws up land deeds), so the same problem doesn't come back when one of you sells.

## Step 5: court as a last resort

If mediation fails, a boundary dispute can go to the District Court (Pengadilan Negeri) as a civil claim. That means time, legal fees, and almost certainly the end of good relations next door.

Before going that way, ask yourself how much land is at stake and whether it's worth the cost and time. Have a lawyer assess how strong your evidence is. If the problem involves double or overlapping certificates, the route can be different. Our guide on [avoiding land disputes](/en/artikel/menghindari-sengketa-tanah/) covers that.

## Keeping it from happening again

Once the line is clear, a few simple habits keep it clear for years:

- **Set permanent markers.** Concrete markers last longer than timber, especially on wet ground. If the land will be filled, record each marker's position with photos and measurements from a fixed point, like a power pole or a building corner, so it can be found again.
- **Document it.** Photograph every marker against something recognisable, and keep the photos with the berita acara and the certificate.
- **Build slightly inside the line.** When putting up a fence or wall, leave a small gap from the boundary. Eaves and gutters shouldn't cross the line either.
- **Bring the neighbour in when you build.** Ask them to look at the fence position before the concrete goes in. Five minutes of talk costs less than tearing a fence down.
- **Put side agreements in writing.** If there's a verbal deal about a footpath, a drain or a tree on the line, write it down and both sign it.

## If you're the buyer

Boundary disputes are cheapest to prevent before you buy. During the viewing:

- Ask the seller to show the markers at every corner.
- Compare the shape and size on the ground with the survey map.
- Ask the neighbours on both sides whether there's ever been a disagreement.
- If markers are missing or doubtful, ask for a boundary re-marking before the AJB, and agree who pays for it.

## The short version

Start with your documents, then a friendly conversation, then an official survey through BPN. Mediation at the kelurahan or the land office settles most of what's left, and court only comes in when everything else is stuck. Once the line is clear, set permanent markers and keep the berita acara with your certificate.

## Common Questions

### Where do I go to sort out an unclear land boundary?

The local land office (Kantor Pertanahan, part of BPN). An owner can apply for pengembalian batas, a measurement that puts the boundary markers back according to the certificate and its survey map.

### Does a boundary dispute have to go to court?

No. It usually starts with a talk with the neighbour, then mediation at the RT, kelurahan or village level, or at the land office. Court is the last resort if all of that fails.

### What if the neighbour's land has no certificate?

The measurement still works from the registered land data. Bring old papers such as a segel or land statement letter, and involve the kelurahan or village office, which usually knows the history of land in its area.
