Subscription and share purchase agreements (tegningsavtale, aksjekjøpsavtale)

Buying existing shares and subscribing for new ones involve different legal rules. A purchase gives you a seller to claim against. In a subscription, the investment agreement and company-law remedies matter, and registration sharply limits your ability to undo the subscription.
Practitioner13 min readLast reviewed 2 September, 2026 Norwegian lawFrom the founder’s perspective

When investing in a Norwegian company, you can buy existing shares or subscribe for new ones. Your choice determines what remedies you have 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 The Supreme Court rescinded a share purchase where an undisclosed claim of more than two million kroner surfaced after completion.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. Statutory buyer remedies therefore do not apply.

Registration normally makes the subscription binding despite grounds of invalidity, subject to the exceptions in aksjeloven § 2-10, applied through § 10-7. Damages claims can remain available under the agreement, § 17-1 or general liability rules. Do not assume that fraud automatically lets you recover the subscription payment after registration.

When subscribing, you depend more heavily on the wording of the documents than when buying existing shares. 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

Review each clause of the proposed agreement before agreeing 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. Record responsibility and contractual deadlines as well as the statutory requirements.
Subscription and payment mechanicsHow and when you subscribe, where you pay, and what happens if the round is undersubscribed. Under § 10-13, cash normally goes to a blocked subscription account until registration; the resolution can permit direct payment to the company. Check the minimum-round condition and repayment terms. Never pay before the resolution exists.
Warranties and remediesThe agreed protection alongside any statutory or negligence-based claims. 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. In Norwegian angel practice, founders are asked to guarantee a short, specific set of matters.

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. Employee software normally transfers under åndsverkloven § 71; other employee work follows purpose-based rules. Inventions have a separate procedure under arbeidstakeroppfinnelsesloven. Verify the rights and keep written evidence, including any contractor licences or assignments.
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 the agreement to state the total warranty-liability cap and the contractual claim period after completion. Both are negotiated for the particular investment. Silence leaves those contractual limits unsettled; it does not remove statutory limitation rules or make liability last forever. Check the time limit, its starting point and any notice requirements together.

Remedies when a warranty breaks

The agreed remedy determines what you can recover if a warranty is breached. 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. The documents must specify who funds the subscription and whose ownership is diluted.

New compensation shares require a valid capital increase, payment and registration. Set-off requires a claim against the issuing company and the prescribed board report and auditor confirmation. A claim against founders personally cannot pay for a company share issue; a founder share transfer or cash settlement is a different route. Have counsel specify the mechanism and capital-protection limits.

The share purchase agreement (aksjekjøpsavtale), clause by clause

Buying existing shares from a founder or an early shareholder involves a simpler agreement and different risks. 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. Read the scope and limits of both title and company warranties; neither should be assumed from the label. 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. Agree a fixed price or adjustment mechanism and assess whether an escrow or holdback is proportionate to the warranty risk. 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.

For existing shares, the sale agreement determines when ownership passes between seller and buyer. Exercising rights against the company is a separate question under § 4-2. New shares follow the capital-increase rules below.

  • 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 after the company received notice of the acquisition (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 enter you in the share register without delay once you have notified and substantiated the acquisition, unless a transfer restriction under § 4-15(2)–(3) prevents it (§ 4-7).
  • For existing shares, rights can generally be exercised from entry in the share register or once the acquisition is notified and documented, provided no statutory or articles-based transfer restriction blocks it. Dividends, other distributions and pre-emption in new issues are exceptions to that condition. Until the rights pass, the seller may exercise them (§ 4-2).

Completion mechanics of a share issue

Completing the share issue depends on following this sequence and meeting the three-month filing deadline. 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 addresses existing shareholders’ pre-emptive rights in a cash issue (§§ 10-4, 10-5), setting them aside where the allocation requires it. 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 full contribution must be received and confirmed before filing.
  5. Payment is confirmed. For a cash contribution the confirmation may come from an auditor, a Norwegian or EEA financial institution, a lawyer or a state-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

Collect the closing pack in stages. Before payment, check the signed resolution, your subscription, the agreed conditions and payment instructions. Payment and its confirmation precede filing. Require the company to deliver the registration evidence and updated share register afterwards, with named responsibility and a contractual long-stop date.

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.

You can avoid many closing problems by asking the founders a few questions before paying. Ask in writing and keep their answers with the closing documents.

  • 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?

Your next steps depend on your experience. The distinction between subscribing and buying also matters.

  • 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 clause specifying whether contractual remedies are exclusive. 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 for written evidence that the company has the rights it needs to work done before incorporation and by contractors. Review assignments, licences and any applicable statutory rights.
  • 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 unless the agreement changes that position. Read the contract for complaint deadlines, price reduction, damages and rescission.
  • Subscribing for new shares is not a purchase. Negotiate the warranties and remedies; statutory and negligence-based damages claims may also be available.
  • Identify who gives each warranty and how a claim would be paid. Cash, transfers of existing shares and new compensation shares require different arrangements.
  • A capital increase must be filed within three months of the subscription deadline. Late filing releases subscribers; money in a blocked subscription account must be repaid without delay.
  • Check the resolution, subscription terms and payment instructions before paying. Obtain payment confirmation, evidence of registration and the updated share register at the stages when they become available.
