Ransom strips and the access they control

A ransom strip land holding is a narrow piece of land, often a metre or two wide, sitting between a development site and the thing the site needs: the public highway, a sewer, a footpath link or an electricity connection. Its owner cannot develop it. What they can do is refuse to let you across it, and charge for the privilege of changing their mind. Because planning permission conveys no rights over anyone else's land, a permission can be granted for a scheme that cannot lawfully be built.

That gap between consent and delivery is where the money changes hands.

What a ransom strip is

The strip has no legal definition. It is a commercial description of land whose only value comes from the fact that somebody else needs it, and the alternative name of a ha-ha strip describes the same arrangement.

Two features make one effective. It has to sit across the only viable route for whatever the development needs, and it has to be owned by someone other than the developer. A strip that can be bypassed by an alternative access, however awkward, is worth much less, which is why the first question on any strip is whether there is a second way in.

Strips control more than vehicular access. A retained verge can block a footway connection needed for a highway agreement. A strip along a boundary can prevent a sewer connection or a service run. On some sites the ransom element is not the access at all but the land needed for a visibility splay.

How strips arise in title

They are rarely accidental, though some are.

• Deliberately retained on a sale. A farmer selling a paddock keeps a strip along the road frontage, so that if the paddock ever gets residential consent the value uplift has to be shared.
• Left over from a previous phase. A developer builds a cul-de-sac, transfers the roads to a management company or retains the verges, and the adjoining field behind is then landlocked.
• Historic conveyancing. Nineteenth century transfers often stopped short of the road, leaving an unregistered sliver whose ownership nobody has established since.
• Uncertainty at the highway boundary. Where the adopted extent stops short of the title boundary, the intervening land belongs to someone, and it may not be you.
• Unadopted roads. A private road serving a group of houses is owned by somebody, sometimes by the frontagers in parts, sometimes by a long dissolved company.

The last two cause the most trouble, because the owner may be unknown and there is nobody to negotiate with at all.

Why a permission can still be granted

Planning permission is permission to develop, not authority to trespass. The authority is not concerned with whether you own the land, and it cannot refuse permission on the ground that you do not, although it can refuse where a scheme has no reasonable prospect of being implemented at all.

So you can apply for and obtain permission over a strip you do not control. Plenty of promoters do, deliberately, because a permission establishes the development value that the strip owner will then want a share of. The risk is the mirror image: the strip owner can apply for something on their land, or simply sit still, and the permission runs down its three years.

Where access is designed across land you do not own, the Transport Assessment or transport statement still has to show a compliant access with adequate visibility. An access design that only works with land you cannot get is a refusal reason in itself, quite apart from the title problem.

Ownership certificates and notice

Every application requires a certificate about ownership, and getting it wrong is a criminal offence rather than a procedural slip.

Ownership for this purpose includes the freehold and a leasehold with a stated minimum unexpired term, so a tenant may need notice too. There is also a separate certificate about agricultural tenants.

If the red line of your application includes the ransom strip, you cannot sign Certificate A. Serving notice under Certificate B tells the strip owner exactly what you are planning, which is sometimes the point and sometimes a mistake. Drawing the red line to exclude the strip avoids the notice but leaves a scheme with no access inside the application site, which officers notice. Neither option is comfortable, and the choice is a negotiating decision rather than a procedural one.

Grampian conditions and their limits

The usual planning solution is a negatively worded condition preventing development until works on third party land have been carried out, for example that no dwelling is occupied until the access has been constructed to an approved specification.

These conditions are lawful and common, and there is a limit on them. The courts have held that such a condition should not be imposed where there is no reasonable prospect of the required action being performed within the lifetime of the permission. So a Grampian condition works where the strip owner is negotiating, and it does not rescue a scheme where the owner has refused outright and said so in writing.

Practically, that means the objection you least want in the file is a letter from the strip owner stating that access will never be granted. Officers read it, and it converts a conditionable issue into a reason for refusal. The Planning Statement should therefore address deliverability squarely where a third party interest is known, setting out what negotiation has taken place, rather than leaving the point to be raised by someone else.

Highway adoption and third party land

Adoption is where strips bite hardest. A highway authority entering into an agreement to adopt new streets needs the developer to own or control the land being offered, together with any land needed for sightlines, drainage and street lighting. It will not adopt over land in third party ownership.

The same applies to works to the existing highway under a separate agreement: the authority controls the adopted highway itself, but if the ransom strip lies between your site boundary and the adopted extent, the connection cannot be made without the strip owner's land.

Service connections raise the same problem in a different form. Statutory undertakers have powers in the street, but not across private land, so an easement is needed for a connection crossing a strip. Set out the constraint in the Utilities Assessment rather than assuming the connection will follow the permission.

Negotiation and valuation

The valuation reference point is the Lands Tribunal decision in Stokes v Cambridge Corporation, where a proportion of the increase in value attributable to the access land was allocated to it. The one third figure often quoted from that case is a starting point in negotiation rather than a rule, and the actual share depends on the strength of the strip owner's position, the existence of any alternative access, the size of the uplift and the risk each side carries.

Things that strengthen the developer's position: a viable alternative access, an existing right of way in the title, a strip in multiple or unknown ownership where the development can wait, and a strip so small that the owner's costs of resisting outweigh their gain.

Things that strengthen the strip owner's position: no alternative, an allocation or permission already in place that fixes the value, a developer with an option running down, and a strip wide enough to carry the visibility splay as well as the carriageway.

Illustrative example: a 22 unit site behind a row of houses, with a two metre strip along the frontage retained by the family that sold the field in the 1980s. The promoter obtains outline permission with a Grampian condition, having opened negotiations and documented them. The strip is eventually acquired for a share of the uplift, and the option agreement had been written with a long enough term to survive the negotiation. The term of the option did more work than the planning strategy.

Checking title before you buy

Almost every ransom strip problem is discoverable before exchange, and most are found late.

1. Obtain official copies of the register and title plan for the site, and read the plan against an up to date topographic survey rather than a small scale map.
2. Ask the highway authority for its record of adopted highway and the extent of adoption at the frontage, and overlay it on the title plan.
3. Look for a gap between the title boundary and the adopted extent, and treat any gap as a strip until proved otherwise.
4. Check the register for existing rights of way, easements and any restrictive covenant that would limit the use even if access is available.
5. Search for adjoining registered titles that include a narrow frontage parcel, which is what a deliberately retained strip usually looks like on a title plan.
6. Where land appears unregistered, take advice on who is likely to own it and how long establishing that will take.

None of this is expensive at the point of acquisition. All of it is expensive afterwards.
