Capital increase in a company

The capital increase is one of the most common procedures in the business world. It allows a company to increase its financial capacity and, to complete this process, specific steps must be followed. For this reason, at JLA Notarios we provide our clients with a team of experts in Commercial Law and companies to meet their needs.

We can process your capital increase either in person, if you come to sign at our Notaría Barcelona. And if you wish, we can also process your capital increase entirely digitally, handling every single one of your procedures online and signing your capital increase from anywhere you are, through notarial videoconference signing.

What is the service or act of capital increase?

The capital increase in a limited company is regulated by company law and is a type of financing operation for a business that allows its share capital to be increased. In this way, the own funds available for the business can be increased. In any case, it is necessary to analyse it on an individual basis. It is essential to ensure legal compatibility, which is established in Spanish legislation and also in the company’s own articles of association.

This additional capital injection allows a business to face new challenges for the future. These may include entering new markets or even reducing debts. When setting the price of the shares, several different methods can also be used. On the one hand, the price of the old shares can be maintained and, on the other, the price of these can be increased.

Types of share capital increase

Capital increases can be classified according to the purpose they contribute to the share capital of a company. We present them below:

  • Capital increase with cash contributions: money is contributed by new partners or partners who acquire more capital. In addition, a share premium can be established, which is common in practice.
  • With non-cash contributions: movable or immovable assets are contributed that are not money but must be registered and valued in euros (Capital Companies Act, articles 61 and 63 respectively). It is worth highlighting the contribution of cryptocurrencies in companies in this classification. This form of capital increase is considered an intangible asset.
  • By debt compensation: part of the company's liabilities or debt is converted into shares or stock to resolve cash flow and indebtedness difficulties.
  • Capital increase charged to reserves: capital is increased with the profits obtained by the company. In theory, it offers guarantees to creditors and potential investors.
  • With share premium: this is a financial operation with the issuance of new shares offered to the company's shareholders at a price higher than the nominal value of their existing shares. It is very common in practice and ensures that those who receive capital pay the true value of the company.
  • By conversion of convertible bonds into shares: shares are issued in exchange for "bonds". The conversion of bonds into shares increases the share capital to finance projects, reduce debts or support other financial needs and eliminates the need to pay interest on these bonds. Among the advantages for bondholders is their conversion into shareholders, gaining ownership rights and obtaining profits through dividends or the value of the shares.

The responsibility of the contributor

In accordance with article 64 of the Revised Text of the Capital Companies Act, the transferor of movable or immovable property or rights assimilated thereto is obliged to deliver and guarantee the item contributed, according to the terms established by the Civil Code for the contract of sale. Furthermore, the rules of the Royal Decree of 22 August 1885, which approves the Commercial Code, shall apply regarding the transfer of risks.

If the contribution is a good or right, the contributor shall be responsible for the reality of what is contributed and for its ownership.

If the contribution consists of a credit right, the contributor shall be responsible for its legitimacy and for the solvency of the debtor.

If a business or establishment is contributed, the contributor shall be obliged to guarantee the whole, if the defect or eviction affects the entirety or any of the essential elements for its normal operation.

Steps to complete a capital increase

In general terms, there are two ways to carry out this type of procedure. On the one hand, by increasing the number of shares; on the other, by increasing their nominal value. Both existing shareholders and any other individual have the right to acquire these new shares. However, previous shareholders will always have a preferential right to acquire the new social participations issued.

In this way, they can maintain their percentage of participations within the company itself or sell their rights. On the other hand, third parties who wish to enter the company's shareholding must first purchase their rights in order to be eligible to acquire the new shares.

Furthermore, when increasing the company's share capital, old shares can also be exchanged for others with a higher nominal value. When completing this procedure, credits can be paid to creditors or bonds converted into shares. Additionally, a greater share capital can be contributed, which will be converted into shares. We will explain later the different methods for increasing share capital.

The increase of share capital must be agreed upon by the general meeting before proceeding to amend the company’s bylaws.

Both the directors and the partners who are going to subscribe to participations or shares in the capital increase must go to a Notary to sign the capital increase, which will be reflected in the Commercial Registry.

Agreement on capital increase in limited liability companies

In this type of company, more than half of the votes at the general meeting corresponding to the shares into which the capital is divided will be required to approve the capital increase.

The agreement in public limited companies

In public limited companies, the regulation requires the attendance of shareholders representing 50% of the subscribed capital with voting rights at the General Shareholders' Meeting on the first call, while on the second call the attendance of 25% of such capital is sufficient. The resolution to increase or reduce capital must be voted on independently of others and will be adopted by an absolute majority if it exceeds 50% of the capital present at the first call. In the case of a second call, the favourable vote of two-thirds of the capital present at the meeting will be required.

The role of the Notary in a capital increase

The Notary is a legal professional with extensive training and considerable experience. Among their functions is advising and counselling impartially and free of charge.

Applying total impartiality, the Notary's mission is to inform all parties involved equally, providing greater assistance to the party that needs it most. Whatever the notarial procedure or act being considered, it is advisable that the interested party, when in doubt, does not hesitate to make the necessary enquiries, both on the day of signing and in the days prior.

In the capital increase of a company, the Notary certifies the authenticity of the agreement, as well as that all documents related to the capital increase comply with laws and regulations, authenticates the signatures of the parties involved, and helps to guarantee legal security and the validity of the procedure carried out.

Documentation to sign a share capital increase at the Notary

To sign the increase of share capital before a Notary and to execute the deed of capital increase, the presentation of the following documents is required:

  • Valid identification document of the administrator or representative of the company. This will be the DNI or residence card or passport plus NIE.
  • Certification of the capital increase adopted by the company in its general meeting or by its partner, the stipulated amount and the method to proceed with its management. If necessary, the notary office can assist you in the preparation of this document prior to signing.
  • Supporting documentation: if the capital is to be increased through cash contributions, a bank certificate of the payment of the contribution must be presented. In the case of non-cash contributions, a report with the valuation of the contributions made by the company’s administrative body must be presented.
  • Documentation of the company and its representative: documentation relating to the company will be necessary, such as the authentic copy of the deed of incorporation of the company or those related to the amendment of the company bylaws. However, this requirement can be replaced by consulting the company information in the Mercantile Registry.
  • Real ownership certificate: authentic copy of the notarial deed identifying the partners who hold more than 25% of the company’s share capital at that time. The act of increasing share capital modifies the capital percentages of the current partners or causes the entry of new partners, which may result in the creation of a new Real Ownership Certificate.

Processing a capital increase at a notary's office

The price of notarial acts is regulated by the Government and complies with the regulatory framework of the NOTARIAL FEE SCHEDULE (RD 1426/1989, of 17 November, regulating the Notaries' Fee Schedule). In the case of a capital increase, the registration cost of the deed must also be considered, taking into account the operation, its economic value, or the number of registrations to be made, among others.

However, the exact price of a notarial document cannot be calculated until its specific content is known, that is, until it is signed, as many circumstances can cause it to vary. The number of copies requested of a document, the number of pages it contains, as well as possible changes or additions, can slightly alter the final price.

If you wish to receive a detailed quote, we invite you to contact us directly through the channel that is most convenient for you. You can do so via the contact form on the main page of this website, through the contact section found in the footer of the website, using the direct WhatsApp access at the bottom right of this page, by sending an email to bcn@jlanotarios.com, or by calling us on 93 159 17 62.

As a guideline, we can inform you that, according to the current regulatory framework, the usual price of the notarial act necessary for the formalisation of a CAPITAL INCREASE before a notary for an amount of €10,000 ranges between €320 and €550, including VAT. Meanwhile, the price of a capital increase before a notary of €100,000 is between €500 and €900. One of the main criteria that increases the amount is whether there are contributions of real estate or not.

Furthermore, the price variation range for capital increases of the same amount is due to the different number of documents to be submitted in the various cases of increases and because, in some cases, more or fewer procedures need to be carried out, so we provide the usual price range for capital increases, which must then be specified according to the type of increase and the specific case.

This indicative price has been calculated for a document of usual content and with the issuance of the necessary copies in the most common cases.

We answer frequently asked questions about the capital increase

It is a right that members of companies have to obtain preference in taking on new shares or participations in proportion equal to those they already held in the company in cases where a capital increase is agreed by the board. The objective is to maintain their participation in the company’s capital to prevent it from being minimised compared to other shareholders.

This pre-emptive subscription right is granted in capital increases with the issuance of new participations or shares, provided that it is carried out through monetary contributions. Therefore, in increases through non-monetary contributions, this pre-emptive right should be understood as waived.


Yes, by board agreement, the partners can expressly waive this right at the same time as agreeing the capital increase so that third parties can enter the company's capital as partners.


The share premium is a very common mechanism in capital increases that allows the partners who participate in the increase to pay the real value corresponding to the percentage of the company they acquire.

Therefore, if there is a share premium, the partners entering a capital increase will pay, for the new shares or stocks they receive, an amount higher than the nominal value of the shares. Thus, alongside the nominal value of the shares or stocks they subscribe to, the new partners will pay the share premium.


As a general rule, capital increases are subject to the Corporate Transactions Tax, but exempt from payment of the tax. Therefore, as a general rule, capital increases do not entail tax payment but must be declared to the Tax Office as exempt.

At JLA Notarios we offer a comprehensive service in capital increases and Company Law, so we can handle the tax declaration of the capital increase deed signed at our notary office in Barcelona on your behalf.

The exception is that there is one case in which capital increases are taxable, which is when the capital is increased with the contribution of a mortgaged property and the company assumes the payment of the debt secured by the mortgage. In this case, the Transfer Tax on Onerous Property Transfers should be paid on the outstanding mortgage capital.


Yes, the deed of capital increase must be registered in the Commercial Registry, to record the new amount of share capital.

As JLA Notarios offers a comprehensive service in matters of companies and capital increases, if you wish, we can take care of the registration procedures for your deed of capital increase in the Commercial Registry.


As a general rule, a capital increase does not need to be registered in the Property Registry, but only in the Commercial Registry.

However, there is one case in which the deed of capital increase must be registered in the Property Registry, which is when the capital increase is made with a non-monetary contribution consisting of a property.

At JLA Notarios, if you wish, we can process any registration procedure in any registry for the capital increase deeds you sign at our notary office.


Yes, it is possible, although it is not the most common case. In practice, it is known as a concertina operation and is used to try to resolve difficulties that may arise during the life of companies.


The released procedure also consists of the payment being made from the company's reserves. If it is 100% released, this will mean that it is completely free for the shareholders. By increasing the number of shares to be distributed, the price of the securities will decrease for each one.
