How do you know where your property boundary is?

This note is for due diligence. It is not legal advice, and it is not a determination of your boundary. Only the process the statutes provide can fix a disputed line. Instruct an advocate if you are already in a conflict.

A title deed does not point at a beacon. A neighbour’s wall is not, by itself, the legal line. A phone GPS pin is not a cadastral survey. If you need to know where the property is, you are asking a survey question that Kenyan statute has already answered — approximately, unless someone has done the work to fix it.

Approximate first — that is the default

The Land Registration Act, 2012, section 18 is the starting point. Unless it is noted in the register that the boundaries of the parcel have been fixed, the cadastral map and any filed plan are deemed to indicate the approximate boundaries and the approximate situation only.

The Land Registration (General) Regulations, 2017 follow that logic in the property section: they record an approximate area, the cadastral sheet number, and a cadastral plan number only for parcels with fixed boundaries. If there is no such note and no such plan, the law itself tells you the map may be close, not conclusive. “I have a title” is not the same as “I know the line.”

Section 18 also channels disputes. The court is not to entertain proceedings on the boundaries of registered land unless those boundaries have been determined in accordance with that section. Jumping to a suit with only a title and a story is usually the wrong first move. The Registrar can receive evidence of the situation on the ground; where the boundaries have already been defined under section 19(3), an uncertain line is determined as stipulated in the Survey Act (Cap. 299).

How a boundary becomes fixed — and what section 20 actually does

Section 19 is the fixing process. If the Registrar considers it desirable, or if an interested person applies, the Registrar gives notice to the owners and occupiers of the adjoining land, gives persons on the register a hearing, causes the precise position to be defined by survey, files a plan, and notes in the register that the boundaries have been fixed. Where dimensions and boundaries are already defined by a plan verified by the survey authority, a note is made and the parcel is deemed to have had its boundaries fixed. That is an official act. It is not a WhatsApp agreement between neighbours, and it is not a contractor’s string line.

Section 20 is maintenance. Every proprietor must keep in good order the fences, hedges, stones, pillars, beacons, walls and other features that demarcate the boundaries. A tidy hedge is a duty. It is not proof that the register has fixed the line.

Beacons, plans and the Survey Regulations

On the ground, a boundary that has been surveyed is marked. The Survey Act requires trigonometrical stations, fundamental benchmarks and boundary beacons that define a holding to be shown on the plan attached to, or referred to in, instruments that deal with that land. A licensed surveyor is responsible for the correctness of the survey. No land is deemed surveyed or resurveyed until the plan is authenticated by the Director of Surveys, an authorised Government surveyor, or the seal of the Survey of Kenya.

The Survey Regulations (Legal Notice 168 of 1994, as revised) govern how those marks are placed, referenced and checked, and who may assist. Field help is not a substitute for the licence: an approved assistant works only under the licensed surveyor’s direct personal control, and the surveyor remains fully responsible.

If a beacon is lost, you do not guess a new one from a tree or a hedge. Restoration is survey work: control, records, and a licensed surveyor. Rational thought and the regulations agree. A replaced mark that is not in the system is just another argument.

Occupation, common law and what you can see

Paper and possession often disagree. Fences move. Roads eat a strip. A parent’s “this is where we have always cultivated” can sit metres off the cadastral line.

Common law has always treated long use, acquiescence and possession as facts that matter — and Kenyan statute does not pretend the register is the whole world. A proprietor’s title is held subject to what is on the register and to overriding interests under the Land Registration Act (section 28): rights being acquired by limitation or prescription, certain rights of way, customary trusts, and other burdens that need not appear on the title. The Land Act, 2012, and its regulations, sit beside that: how land is administered, and how transfers, leases and charges are completed. A charge on the parcel is a dealing question for the advocate. Encroachment on the ground is a survey question.

So: walk the land. Note who occupies what. Photograph beacons if they exist. Speak to neighbours. Then compare that to the cadastral map and the official search. If the stories diverge, that is the job — not a reason to raise your voice at the fence.

Planning lines are not property lines

The Physical and Land Use Planning Act, 2019 (sections 57 to 59) and the Physical and Land Use Planning (General Development Permission and Control) Regulations, 2021 control use and development, not the cadastral line. You need development permission to develop; the plans are to be prepared by a qualified person; change of user and subdivision are planning acts. A road reserve, a building line or a zoning setback can constrain what you may build even when the cadastral boundary is clear.

Do not ask a planner to define your beacon, and do not ask a surveyor to grant development permission. They answer different statutory questions. A topographic survey for an architect (levels, not title) is again a different product from a cadastral boundary survey.

What to do, in order

1. Official search and cadastral extract — so you know the parcel the law is talking about, and whether a cadastral plan number suggests the line has been fixed.
2. Inspect: occupation, fences, visible marks, access.
3. If you only need to understand risk before a purchase: a Land Check (records and a first spatial look).
4. If the line must be shown on the ground: field survey by a licensed surveyor, under the Survey Act and Regulations, with a plan that can be authenticated.
5. If neighbours dispute the line: advocate plus survey. Use the Registrar’s section 19 process. Do not skip it for a “gentlemen’s agreement” you cannot register.

If you want to know where the property is — approximately or, if the job requires it, by survey — start with the records and the ground, not the seller’s map.
