Subscription and share purchase agreements (tegningsavtale, aksjekjøpsavtale)

Buying existing shares and subscribing for new ones look like one transaction and are two legal regimes. A purchase is a sale with a seller to claim against; a subscription in a share issue is a corporate act with no statutory buyer remedies at all, so the protection is whatever was contracted.
Practitioner12 min readLast reviewed 2 september, 2026 Norwegian lawFrom the founder’s perspective

Money reaches a Norwegian company through your hands in one of two ways, and which one decides what you can do if something turns out to be wrong.

Buying existing shares from a shareholder is a purchase, and the Sale of Goods Act (kjøpsloven) governs it (kjøpsloven § 1). You have a seller to claim against and a statutory remedy set: a duty to complain within reasonable time, price reduction, damages, and rescission where the defect is material.

The remedies are real. The Supreme Court rescinded a share purchase where an undisclosed claim of more than two million kroner surfaced after completion.

Subscribing for new shares in a share issue (emisjon) is not a purchase, and there is no seller. The shares do not exist until the company creates them by a corporate act under the Companies Act (aksjeloven) chapter 10, and the money goes into the company you are becoming a co-owner of. The buyer remedies have nothing to attach to.

Once the increase is registered, the capital-protection rules that keep the share capital intact stand in the way of unwinding a subscription. You are left with what you contracted for, plus the general rules of contract law in cases of dishonesty or gross unreasonableness.

Subscription therefore carries more documentary risk than purchase. The agreement has to give you what the statute gives a buyer, and founder guarantees are how Norwegian practice does it.

The subscription agreement (tegningsavtale), clause by clause

Read the draft you are sent against this, clause by clause, before you agree a price. The subscription agreement is often bundled with the wider investment agreement; it is the contract around the corporate act and cannot replace the act.

ClauseWhat it does, and what to watch for
Parties and the company’s roleNames the investors and makes the company a party, so obligations owed to you are owed by an entity that exists after completion. Company, founders and incoming investors all sign; existing shareholders sign the accession points. Watch for an agreement between investors and founders only, which leaves the company owing you nothing.
The roundStates the pre-money valuation, the amount raised, the subscription price per share and the resulting ownership. Insist on the share count as well as the percentage. A percentage on its own drifts when the option pool moves.
Conditions to subscriptionLists what must be true before you pay: diligence closed, the shareholders’ agreement signed, key employment and intellectual-property assignments in place, no material adverse change. Conditions should be objective and dated. Watch for conditions so loose that either side can walk, or so tight that the round cannot close.
Corporate undertakingsObliges the company to hold the general meeting, pass the resolution under aksjeloven § 10-1, set aside the pre-emptive right where needed and file on time, with an express deadline for the registration filing. Silence on these steps leaves your money in the company with no obligation to complete them.
Subscription and payment mechanicsHow and when you subscribe, where you pay, and what happens if the round is undersubscribed. Standard practice is payment to a dedicated share-issue account, and a minimum-round condition with repayment if it is not met. Never pay before the resolution exists.
Warranties and remediesThe substitute for the statutory remedies you do not have. Watch for a warranty catalogue with no remedy attached to it.
Use of proceeds and reportingWhat the money is for, and what you will be told afterwards: a short milestone statement and a reporting rhythm. Silence here is common and worth fixing before you sign.

Warranties and founder guarantees in a subscription

With no seller to claim against, the warranty catalogue is your protection, so check the draft against this list and ask for whatever is missing. Norwegian angel practice, as NorBAN has taught it, asks the founders to guarantee a short and specific set.

WarrantyWhat it covers, and why it is on the list
Ownership of intellectual propertyThe company owns what it says it owns, including work done before incorporation and by contractors. Norwegian law does not assign employee-created intellectual property to the company by default. The Employee Inventions Act (arbeidstakeroppfinnelsesloven) covers inventions made in the course of employment and the Copyright Act (åndsverkloven) § 71 computer programs; anything outside those needs a written assignment.
No third-party claimsNo one outside the company has a claim over its assets or technology. A former employer or co-founder surfacing later is a company-ending event.
Taxes and value-added tax paidFilings made, liabilities settled or provided for. Unpaid public claims follow the company, so they become your problem.
Valid contractsMaterial contracts are in force, and no change-of-control clause is breached by the round. A key customer contract that terminates on investment can undo the case for investing.
No disputesNo litigation or dispute pending or threatened. Disclosed disputes are priced; undisclosed ones are not.
Full disclosureEverything material given in diligence is accurate and nothing material is withheld. This is the clause that catches what the specific warranties miss.

Who gives the warranties is negotiated. In Norwegian angel rounds the founders are commonly asked to warrant personally, which puts their private assets behind the statements. In the UK model documents the company is now the sole warrantor and founders are not asked to warrant at all.

Neither position is universal. A company warranty is a claim against the company you have just funded, so a successful claim is paid partly with your own money.

Ask for a cap on total warranty exposure and a claim period after completion on the face of the agreement. Both are settled by negotiation, deal by deal. An agreement silent on either leaves the exposure open.

Remedies when a warranty breaks

The remedy the agreement attaches decides what a breach is worth to you in practice. Read it as closely as the warranties themselves.

  1. A claim against the founders personally. You sue on the warranty for the loss suffered. On paper it is the stronger remedy. The founders’ assets are usually illiquid, the claim is against the people the company depends on, and pursuing it can destroy what remains of the value.
  2. Compensation shares. On a breach, the company issues additional shares to you at nominal value, restoring the ownership you would have had at the corrected valuation. No founder cash moves; the founders are diluted. Norwegian angel practice generally prefers this mechanism, since it keeps the team solvent and in place.

Compensation shares are themselves a capital increase, so the mechanism only works if the agreement obliges the shareholders to vote the issue through and the company to file it.

The share purchase agreement (aksjekjøpsavtale), clause by clause

Buying existing shares from a founder or an early shareholder is a simpler document with a different risk. The statutory remedies apply underneath whatever is written, and the transfer rules in aksjeloven chapter 4 stand between signature and ownership, so the conditions and the transfer formalities are the clauses to read hardest.

ClauseWhat it does, and what to watch for
Seller warrantiesTitle to the shares, freedom from encumbrances, and warranties about the company itself. Title warranties are absolute; company warranties are negotiated and often thinner than in a subscription. Watch for a seller who warrants title only, leaving the condition of the company entirely at your risk.
Price and adjustmentThe consideration and any adjustment mechanism or deferred element. Standard is a fixed price, with an escrow or holdback where warranties are material. Watch for a deferred price with no security behind it.
ConditionsBoard consent obtained and the pre-emption period cleared before completion, with completion conditional on both. Watch for signing and paying before consent, when the board can still refuse.
Transfer formalitiesNotice to the company, entry in the share register (aksjeeierbok), and any pre-emption waiver from the other shareholders. The updated register is delivered at completion. Watch for payment made against a signed agreement alone.
Shareholders’ agreement accessionBinds you into the existing agreement and confirms the seller’s release, by an accession declaration signed at completion. Watch for buying the shares without inheriting the protections attached to them.
Relationship to statutory remediesWhether contractual remedies are exclusive of the Sale of Goods Act’s, stated expressly either way. Watch for an exclusivity clause that quietly removes the statutory remedies you were relying on.

When you own what you paid for is decided by statute, and until every step is done you have money out and no shareholder rights.

  • The company must consent to the acquisition unless the articles waive it. The board decides, and consent counts as given if no refusal reaches you within two months (aksjeloven §§ 4-15, 4-16).
  • The other shareholders hold a pre-emption right over shares that have changed owner unless the articles say otherwise (§ 4-19).
  • You must notify the company immediately (§ 4-12), and the company must then enter you in the share register without delay (§ 4-7).
  • Shareholder rights can be exercised only from that entry, or from the acquisition being notified and proven (§ 4-2).

Completion mechanics of a share issue

Your money rides on this sequence, and the three-month filing deadline in it is the one hard date. Find out where the company is in the sequence before you pay.

  1. The board proposes the increase and prepares the supporting documents.
  2. The general meeting resolves the capital increase (aksjeloven § 10-1) with two thirds of the votes cast and of the capital represented, and sets aside the existing shareholders’ pre-emptive right for the issue (§§ 10-4, 10-5) where new investors are coming in. The resolution states the amount, the subscription price, who may subscribe, the subscription deadline, the payment deadline and the rights attaching to the new shares.
  3. Subscription is made in the minutes themselves or in a separate subscription document that reproduces the resolution.
  4. Payment is made per the resolution. The increase cannot be registered until the full contribution is received.
  5. Payment is confirmed. For a cash contribution the confirmation may come from an auditor, a financial institution, a lawyer or an authorised accountant. For a contribution in kind or a set-off, only an auditor may confirm, and a contribution in kind additionally requires a board report confirmed by an auditor, valued no earlier than four weeks before the resolution.
  6. The increase is notified to the Register of Business Enterprises (Foretaksregisteret) within three months of the subscription deadline. Miss that deadline and the resolution lapses and subscribers are released and repaid (§ 10-9).
  7. The new shares confer shareholder rights on registration, unless the resolution provides otherwise, and ordinary shareholder rights arise no later than registration (§ 10-11).

Before you pay, check that the resolution matches the agreement and that the subscription document reproduces the resolution. After you pay, check that the filing goes in. A lapsed resolution means the round has to be run again from the general meeting.

The closing pack as a whole

Refuse to complete until you hold each of these, and keep the set together; it is the proof that you own what you paid for.

DocumentWhy an investor checks it
Signed general meeting minutesProves the resolution behind the issue exists and matches the agreed terms (aksjeloven § 5-16).
Subscription document or subscription listProves you subscribed on the terms resolved, and for how many shares.
Payment confirmationThe statutory confirmation without which the increase cannot be registered.
Registration receipt and updated company certificateProof the increase is registered and the shares exist.
Updated articles of associationThe share capital figure now matches reality.
Updated share registerThe register, not the cap-table slide, is where shareholding is recorded (§ 4-5).
Shareholders’ agreement and accession declarationsYour ongoing rights, binding on everyone who now holds shares.
Investment agreement with the warranty catalogueThe document your remedies live in.

Most of the closing problems can be avoided with a few questions to the founders before money moves. Ask them in writing, so the answers sit in the pack too.

  • Are these new shares or existing shares? The answer decides which remedies you have and whether the start-up investment deduction is available.
  • Has the general meeting already passed the resolution, and does it state the same price, share count and rights as the agreement?
  • Which account do I pay into, and what happens to the money if the round is undersubscribed?
  • Who warrants, up to what cap, and for how long after completion?
  • If a warranty breaks, do I get compensation shares or a claim against the founders?
  • Who is filing with Foretaksregisteret, and by what date inside the three months?

What you do with the answers changes with your experience. It also changes with whether you are subscribing or buying.

  • A first-time angel pays only into the dedicated share-issue account, only after seeing the signed minutes, and asks for the registration receipt as soon as it arrives. Do not accept a cap-table spreadsheet in place of the share register.
  • An experienced angel buying existing shares gets board consent and the pre-emption waiver before money moves, and reads the exclusivity clause. It can quietly take away the Sale of Goods Act remedies that made the purchase route attractive.
  • An angel with a technology focus presses hardest on the intellectual-property warranty. Ask to see the written assignments for work done before incorporation and by contractors, since neither statute covers them.
  • An angel leading a syndicate has one person collect the closing pack and circulate it, so every co-investor is entered in the register and has signed an accession declaration. A co-investor who misses the accession is outside the shareholders’ agreement.

The Norwegian start-up investment deduction applies only to shares acquired at incorporation or through a new share issue, never to a purchase of existing shares. If the deduction is part of your return calculation, the route into the company decides whether you get it. Everything else about the tax treatment of the two routes belongs with your own adviser.

Key takeaways

  • A purchase of existing shares falls under the Sale of Goods Act. Complaint, price reduction and rescission are available against the seller.
  • Subscribing for new shares in a share issue is not a purchase, so those remedies do not exist. The warranties in the investment agreement are the only protection.
  • Founder guarantees are the Norwegian answer to that gap. Compensation shares are the usual alternative to a personal cash claim.
  • A capital increase must be registered within three months of the subscription deadline. Otherwise the resolution lapses and subscribers are repaid.
  • Refuse to complete without the general meeting resolution, the subscription document, payment confirmation and an updated share register.
