When a development joint venture fails, the post-mortem almost never finds a missing spreadsheet; it finds a missing clause. The deals are agreed on ten lines of heads of terms, but they are won and lost in a document set that, as of June 2026, costs £8,000 to £25,000 in legal fees and decides three things the appraisal cannot: who controls the scheme when the parties disagree, whose money moves first when a funding call is missed, and who stands where in the queue when the senior lender enforces. The thin template-contract pages that rank for this search will sell you a generic JV agreement for £50. This guide explains what the real document set contains, clause by clause, with worked numbers.
It pairs with our walkthrough of the full venture life cycle, how property joint ventures work, and with the commercial terms on our JV development finance page. One caveat up front and repeated at the end: this is general information, not legal advice; instruct a solicitor with specific development JV experience before signing anything.
A development joint venture is documented as a set, and each instrument has one job:
| Document | What it does | Typical scope, June 2026 |
|---|---|---|
| SPV articles of association | The company constitution: share classes, transfer restrictions, board mechanics | Bespoke, replacing the Companies Act model articles |
| Shareholders' agreement | Governance, funding obligations, waterfall, reserved matters, deadlock, default, exit | 30 to 60 pages; the core document |
| Loan note instrument | Documents the partner's cash advanced as debt rather than shares | Used in most hybrid equity structures |
| Deed of priority / intercreditor | Ranks the senior lender ahead of shareholder loans and security | Required by every senior development lender |
| Security package | Charges and debentures over the SPV and site for lender and sometimes partner | First charge to senior; partner sometimes takes second-ranking security |
| Personal guarantees | Developer's personal covenant to the senior lender on cost overruns and interest | Typically 15% to 25% of the facility, plus full overrun cover |
The articles deserve a sentence of explanation because developers routinely ignore them. Every company incorporated at Companies House gets the statutory model articles by default, and the model articles are wrong for a JV: they allow share transfers the parties would never permit, and they contain none of the class rights the deal needs. A JV SPV adopts bespoke articles, and the shareholders' agreement then sits on top with a supremacy clause stating that, between the shareholders, the agreement prevails over the articles if they conflict. The agreement is private; the articles are on the public register. Anything commercially sensitive, the split, the priority return, the default mechanics, lives in the agreement for exactly that reason.
The share register is usually simple and deliberately so. The standard pattern gives the developer A ordinary shares and the funding partner B ordinary shares: identical nominal value, separate classes so that rights, board appointments and consents can attach to each class rather than to percentages. Each class typically appoints one or two directors, and the reserved matters list requires B shareholder consent regardless of how many shares each side holds, which is how a partner holding 50% of the equity can hold 100% of the veto on the matters that protect their cash.
Preference shares appear where the partner wants their priority return hard-wired into the capital structure rather than the waterfall: a preference share carries a fixed preferential dividend, say 10% per annum, and priority on a return of capital, mimicking the priority return contractually. In small and mid-market development JVs they are the minority choice, because the same economics are achieved more flexibly with ordinary shares plus loan notes, and a dividend can only lawfully be paid from distributable profits, which a development SPV does not have until the scheme sells.
In most UK development JVs the partner subscribes a nominal amount for their B shares, often £100, and advances the body of their money, the £600,000 on our worked scheme, as shareholder loan notes. The reasons are mechanical. Debt comes back before equity, so the partner's capital can be repaid from sales proceeds ahead of any distribution and without the formalities of a capital reduction. Interest on the notes can replicate the priority return as a deductible cost in the SPV rather than an appropriation of taxed profit. And on failure, a creditor's claim ranks ahead of a shareholder's. Two cautions belong next to that paragraph. Tax first: interest paid by a UK company on loan notes can trigger an obligation to withhold 20% income tax at source, and the deductibility and timing rules are not trivial, so the structure needs an accountant's sign-off against current HMRC practice, not a copied precedent. Ranking second: the deed of priority will subordinate the loan notes to the senior facility in full, which is the subject of the section below.
Reserved matters are the decisions the SPV cannot take without the partner's consent, whatever the boardroom arithmetic says, and the negotiation is all in the thresholds. A typical development list, with the numbers that make it bite: any sale of a unit more than 2.5% below the price in the agreed sales schedule; any variation to the build contract above £15,000 individually or £50,000 cumulatively; any new borrowing, security or guarantee; replacing the contractor, architect or employer's agent; any payment to the developer or a connected party beyond the agreed development management fee, say 1.5% of build cost; approving each year's budget and any spend more than 5% over a budget line; and starting or settling litigation above £10,000.
Read that list against the worked scheme and the design logic shows. On a £2,400,000 GDV development, the gap between the appraised price and a 2.5% discount on one unit is £10,000; six units sold soft is £60,000, which is 12% of a £500,000 profit pool, real money but not control of the business. The thresholds are calibrated so the partner consents to anything that moves their return by more than roughly 1%, and the developer runs everything beneath that line without asking. A reserved matters list with no thresholds, "any sale, any variation, any payment", is not investor protection, it is an operating veto, and it is the single most common over-reach we see in first-draft agreements sent to developers.
Where the venture is 50/50, the agreement must answer the question the share register cannot: who wins a disagreement neither side can outvote. The standard structure is a ladder. A deadlock notice escalates the matter from the board to the principals personally, who must meet within, say, ten business days; failing that, mediation; failing that, the buy-sell mechanism, which exists mostly to never be used.
The two classic mechanisms are brutal by design. Russian roulette: either shareholder may serve a notice naming a price per share; the recipient must then either sell their entire holding at that price or buy the server's entire holding at the same price. Texas shoot-out: both sides submit sealed bids to buy the other out, and the higher bid wins and completes. Worked example on our scheme: mid-build, the partner has £600,000 of loan notes in and the parties deadlock over whether to cut prices. The developer serves a roulette notice valuing the equity at £300,000. The partner now chooses: sell their shares for £300,000 (their loan notes are repaid separately, so this prices only the profit share), or buy the developer out at £300,000 and finish the scheme with a new development manager. The genius and the danger are the same feature: the server must name a price they are willing to transact at on either side, which forces honesty, but the mechanism structurally favours the party with cash. A developer with no liquidity facing a funded partner should resist pure Russian roulette and negotiate a deferred-payment variant or a valuation-based fallback instead, because a roulette notice you cannot afford to accept is not a tie-breaker, it is a transfer of the scheme.
Funding default is the scenario the agreement must price in advance, because mid-build is the worst possible moment to negotiate. The standard remedy is dilution at a punitive ratio: if a shareholder misses a funding call, the other may advance the shortfall and the defaulter's economic interest is diluted as if the rescue money had bought shares at a discount, commonly 1.5 to 2 times the normal subscription terms. Worked: the partner has committed £600,000 in tranches and fails on the final £100,000. The developer (or a replacement funder) advances it under a 2x dilution clause, so the £100,000 counts as £200,000 for waterfall purposes. On the scheme's £410,000 residual profit pool, the recalculated shares move the defaulting partner from £205,000 to roughly £164,000 and hand the difference to the rescuer. The mechanic matters more than the percentages: dilution is self-executing, needs no court, and converts a default from a crisis into a priced event, which is exactly what a senior lender wants to see when it asks, mid-facility, who funds a shortfall.
Drag-along and tag-along govern exits. Drag-along lets a shareholder selling the whole SPV (typically above an agreed threshold, often 50% or 75%) force the other to sell on identical terms, preserving the clean-exit value of the company. Tag-along is the mirror: if one side sells, the other can insist on being bought on the same terms, preventing a partner from selling their position to an unknown third party while leaving the developer behind. Restrictive covenants complete the control set: each party typically agrees not to pursue a competing development within a defined radius, often one to three miles, while the venture runs and for six to twelve months after, and not to poach the venture's contractor or team. Developers should read these against their own pipeline before signing; a covenant drafted for the partner's comfort can quietly sterilise the developer's next two site acquisitions.
Everything above is negotiated between the shareholders; the deed of priority (on larger deals, a full intercreditor agreement) is where the senior lender re-orders it. The deed subordinates the partner's loan notes and any second-ranking security to the senior facility: no repayments of loan note principal or priority return while senior debt is outstanding unless the facility agreement's release conditions are met, a standstill preventing the partner from enforcing security or winding up the SPV without the lender's consent, and the lender's right to enforce first and distribute in order. Where the developer has given personal guarantees on overruns and interest, those sit outside the deed entirely, which is why a developer can be personally exposed on a scheme where the partner's downside is capped at their investment.
From the lender side of the desk, our founder's observation from 25 years at Bank of Scotland and Lloyds Banking Group is that the deed of priority routinely takes longer to settle than the facility agreement itself, and the delay is always the same three clauses: whether the partner may receive any cash before senior repayment (lenders concede agreed-formula priority return payments only on the strongest deals), the length of the standstill (90 to 180 days is the battleground), and cure rights, the partner's ability to step in and remedy a developer default to protect their £600,000. Credit committees read the shareholders' agreement alongside the deed for one purpose: to find out who really controls the SPV when things go wrong, because a lender's recovery depends on someone competent finishing the building. A JV document set that answers that question cleanly, named replacement mechanics, a funded overrun obligation, an enforceable deadlock route, gets a faster credit approval and, at the margin, finer pricing. One that leaves it vague gets conditions precedent and weeks of legal correspondence at the exact moment the land contract is expiring.
Each party instructs its own corporate solicitor; the SPV itself is usually formed and documented by the developer's side, with the partner's solicitor marking up. The realistic budget as of June 2026 is £8,000 to £25,000 plus VAT across the set: a straightforward two-party deal with a standard lender deed at the bottom of the range, landowner equity, multiple investors or a contested intercreditor at the top. Resist two false economies. The £50 template JV agreement is drafted for trading businesses, not development SPVs, and contains none of the waterfall, dilution or priority mechanics this guide describes. And the single-solicitor "we will just use one firm to save money" structure puts one adviser in an unmanageable conflict the first time the parties' interests diverge, which in a development JV is roughly week three. Where the venture also involves arranging investment from third parties, that activity can fall within the scope of FCA regulation, and anything of that nature should be carried out by, or referred to, an appropriately authorised firm: check the FCA register rather than assuming. And to repeat the caveat that belongs on every page about this subject: this guide is general information, not legal or tax advice. Take advice from a solicitor experienced in development joint ventures before you sign, and model the commercial terms you are about to document with the JV profit split calculator and our guide to profit split structures first, because the cheapest legal drafting is the kind that records a deal both sides already understand.
A property joint venture agreement is the contract, in development deals usually a shareholders' agreement around a special purpose vehicle (SPV) company, that fixes how two parties fund, govern and divide the profit of a property project. It records each party's contribution, the priority return and profit split, the reserved matters the funding partner must approve, deadlock and default mechanisms, and the exit. It sits alongside the SPV's articles of association, any shareholder loan notes, the security package and a deed of priority with the senior lender.
At minimum: each party's funding obligation and the timetable for it; the share classes and the economic waterfall (capital back, priority return, then the split); a reserved matters list with thresholds; a deadlock mechanism with a final tie-breaker such as Russian roulette or Texas shoot-out; default and dilution provisions for a shareholder who fails to fund; drag-along and tag-along rights; cost overrun responsibility; restrictive covenants; the development manager appointment and fee; and the exit route with a longstop date. Vague heads of terms convert into expensive disputes through exactly these clauses.
As of June 2026, a properly drafted development JV document set, bespoke articles, shareholders' agreement, loan note instrument where used, and the security and priority documents, costs roughly £8,000 to £25,000 plus VAT in legal fees across both parties. Simple two-party deals on smaller schemes sit at the bottom of the range; deals with landowner equity, multiple investors or a contested intercreditor sit at the top. Each party pays its own solicitor; the SPV's formation cost itself is trivial by comparison.
Only if the documents pretend deadlock cannot happen. A 50/50 shareholding with matched board seats means neither party can outvote the other on anything, so the shareholders' agreement must supply the tie-breaker the share register cannot: an escalation ladder, then a buy-sell mechanism such as Russian roulette (one side names a price, the other must buy or sell at it) or Texas shoot-out (sealed bids, highest buys). A 50/50 venture with a complete deadlock clause is robust; a 50/50 venture without one is a scheme that can freeze mid-build while rolled interest compounds.
The developer gives up unilateral control through reserved matters, accepts forced-transfer mechanics (drag-along, default dilution) that can move their equity at formula prices, usually gives restrictive covenants limiting competing schemes nearby, and commonly still carries personal guarantees to the senior lender that the JV partner does not share. The documents also take four to eight weeks and £8,000 to £25,000 to negotiate, which is dead time on a land contract. Each of these is manageable, but only if negotiated before signature rather than discovered after.
