Practical Guide on setting up your Lux General Partner: how to avoid common pitfalls

For U.S. sponsors looking to set up their Luxembourg fund structure in a partnership form (i.e., by way of a Luxembourg special limited partnership (SCSp), limited partnership (SCS), or partnership limited by shares (SCA)), the incorporation process of the General Partner as a Luxembourg corporation, can sometimes prove to be (much) more involved than anticipated. Due to the (current) Luxembourg law requirement of having the share capital available on a bank account at the onset of the future company, and the bank’s KYC requirements to open such bank account, the process inherently spans over several weeks and sufficient preparation goes a long way to smoothen the experience. 

This post aims to provide a practical, sponsor-friendly overview of what to expect, what to prepare, and where delays most often occur in the incorporation process of your Lux GP, with specific attention to the bank account opening process. Spoiler alert: the Lux authorities have recently introduced a draft bill which may be a complete game changer, speeding up the process significantly.

1) Incorporating the GP: what the process looks like in practice

For Luxembourg partnerships, the General Partner is typically structured as a Luxembourg private limited liability company (SARL) for substance purposes. SARLs are incorporated in front of a Luxembourg notary (a profession quite different from their US counterparts: they are government appointed legal professionals with strict ethical rules and confidentiality obligations which have a monopoly on certain legal acts, including the formation of certain types of corporations). Your Luxembourg law firm will typically interface between you and the notary to ensure seamless communication.

Key decisions to make early

Company name and registered office in Luxembourg

The exact legal name of the GP must be determined upfront (post-incorporation changes are possible, but can be time-consuming and costly, as they require a new notarial deed). Your GP will also need a registered office in Luxembourg. If you do not have a permanent office in Luxembourg, the registered office can easily be provided by a licensed domiciliation agent.

Shareholder structure

The GP is typically held by a single shareholder to simplify future corporate decisions. This sole shareholder needs to exist before you may proceed with the incorporation of your Lux GP. Such sole shareholder can have multiple forms (corporation, trust, partnership, etc.) and can be incorporated in another country than Luxembourg. The full corporate details of the sole shareholder (including its legal name, registered address, and registration number in the relevant corporate registry) and beneficial owners information will usually have to be provided to the notary.

Share capital amount

SARLs require a minimum share capital of 12k EUR, or its equivalent in other currencies (for a capital in USD, count 15-20k USD), which needs to be on the future’s SARL bank account before incorporation.

Management and substance considerations

SARLs are managed by one or more managers. From a substance perspective (for Lux tax considerations), the GP should have at least one Luxembourg-based manager (in practice, sponsors usually appoint two). As a rule of thumb, the number of managers with a professional address in a specific non-Luxembourg country should never exceed the number of Luxembourg-based managers (e.g., a board composed out of one Luxembourg-based, one UK-based and one US-based manager is fine). 

To balance those local substance requirements with control needs, Sponsors often opt for a classified board (commonly referred to as Class A and Class B managers), where one class is composed of Luxembourg-based managers (often independent or provided by a service provider), and the other is composed of Sponsor-affiliated managers that may be based outside of Luxembourg. Any such distinction must be clearly reflected in the GP’s articles of incorporation. It’s worth noting also that all managers must obtain a Luxembourg national identification number (LNIN). Your notary can request such LNIN on behalf of the managers needing it at the end of the incorporation process (more on that below). 

Documents you will be asked to provide

Blocking certificate and proof of funding of the share capital

Luxembourg law requires the share capital of the company to be available on a bank account before the incorporation takes place. To that end, Luxembourg banks will issue a “blocking certificate” to confirm to the notary that this is indeed the case. Some notaries may also accept certificates issued by banks from other EU countries. 

As more fully set out below, this step is often the most time-consuming, as it is entirely dependent on the bank’s AML and KYC review to open a bank account. For this reason, initiating the banking process as early as possible is critical to maintaining your targeted timeline. However, this step may significantly evolve with the introduction of the proposed reform (see below). Some notaries may also ask for proof of the wire transfer to ensure that the capital comes from the sole shareholder.

Draft articles of incorporation

These set out the GP’s corporate purpose, governance framework, and management structure and are executed before a Luxembourg notary. Your Luxembourg counsel will provide you with a boilerplate template with some elections for you to make (classified board, chairperson, capital currency, etc.).

Power of Attorney

To facilitate the incorporation, Sponsors typically provide the notary itself (or, if preferred, their Luxembourg law firm) with a PoA to execute the Articles on their behalf, thus doing away with the need to travel yourself to the notary’s office in Luxembourg.  

Notary KYC Documents: Declaration of beneficial ownership, structure chart and passports

Notaries are subject to KYC obligations and will require a handful of documents to meet them before they can proceed with the incorporation.

As such, notaries will generally require a signed ownership structure chart and UBO declaration. UBOs will be determined in accordance with Luxembourg law (in a nutshell: any natural person with over 25% of direct or indirect voting or holding rights in the GP, or having “control by other means” over the GP, shall be considered a UBO, with specific rules for trusts, and a waiver for listed entities). Expect to also provide a copy of the passport of the UBOs and the managers of the GP (as a reminder, Luxembourg notaries are subject to strict confidentiality obligations when receiving this info). 

Constitutive documents of the sole shareholder and evidence of signatory powers

This generally includes the shareholder’s articles of incorporation or equivalent constitutional documents, together with evidence of its existence and registration.

The notary will also require documentary evidence confirming the authority and identity (passport copy) of the individuals signing the incorporation documents for the sole shareholder (e.g., power of attorney, the UBO declaration, etc).  This is usually a quick process, noting e.g., standing resolutions or Cayman/Delaware manager registers are generally accepted to document this. 

LNIN documents (as needed)

The LNIN is a unique identification number assigned by the Luxembourg register of natural persons, which is required to register the managers with the Luxembourg Business Register. To obtain such number, a copy of the identity card or the passport of the natural person applying for such LNIN will need to be provided to the RCS, along with proof of residence. You do not need to be a Luxembourg resident to obtain a LNIN and obtaining such LNIN will have no Luxembourg tax implications.

After incorporation

• The GP must be registered with the Luxembourg Business Register by the notary within 30 days of incorporation
• The GP must be registered with the Luxembourg Register of Beneficial Owners within 30 days of its registration with the Luxembourg Business Register. The people mentioned in this register shall depend on your ownership structure.

2) Opening a Luxembourg bank account: what really drives timing

Luxembourg banks operate under a stringent AML and KYC framework. As a result, opening a corporate bank account is a structured and highly document-driven process, where preparation is key. 

For fund sponsors unfamiliar with European banking standards, this process can feel demanding. Banks require extensive information not only on the company itself, but also on its governance, ownership chain, and the individuals ultimately controlling or managing the structure. For Luxembourg banks, these requirements stem primarily from Luxembourg’s AML/CFT framework, notably the law of 12 November 2004, under which banks must apply robust “Know Your Customer” (KYC) procedures to all legal entity clients which mostly incorporates EU law into Luxembourg law. 

Understanding this process and preparing for it early can make the difference between a smooth onboarding process and weeks of back-and-forth with the bank. We listed the main steps to keep in mind, so you are ready to start this process.

What banks typically ask before incorporation

While requirements may vary slightly from one banking institution to another, the following items are commonly requested in order to open your bank account:

Corporate documentation of the entity opening the account

This includes the entity’s constitutional documents, detailing its legal form, share capital, shareholder(s), and registered office.

Ownership and structure chart

A dated and signed structure chart showing the ownership chain up to the ultimate beneficial owner(s), including ownership percentage, legal form, and country domicile.

Account currency

Confirmation of the currency in which the account will operate.

Full description of the purpose and expected activity of the account

A clear explanation of the entity’s role within the broader structure, together with details of the anticipated transactions on the account, such as transaction types, expected volumes and amounts, and the relevant jurisdictions involved.

Once these elements have been submitted and reviewed, the bank is generally in a position to issue an IBAN to allow the funding of the company’s share capital. Following receipt of the funds, the bank can then issue a blocking certificate, which must be provided to the Luxembourg notary as part of the incorporation process.

Regulatory developments to watch

As touched upon above, under the current Luxembourg legal framework, the incorporation of a private limited liability company (SARL) requires a minimum share capital of EUR 12,000 (or equivalent in another currency), which must be fully paid up at the time of incorporation. This rule, rooted in legislation dating back to the 1930s and inspired by the legal environment of that era, no longer reflects the realities of today’s business landscape. Given the increasingly strict banking and compliance checks, this step can significantly slow down incorporation timelines. 

To bolster Luxembourg’s attractiveness, the new Luxembourg draft Law No. 8669¹, introduced before the Luxembourg Parliament on 16 December 2025, seeks to remove this hurdle.  The bill proposes allowing the statutory minimum share capital of a Luxembourg private limited liability company to be paid at a later stage (up to 12 months after incorporation), thereby easing incorporation requirements and improving flexibility for new businesses. If adopted in its current form, this would mean that a blocking certificate shall not always be required anymore for the incorporation, thus significantly speeding up the incorporation process.

Certain safeguards would however remain. For example, (i) the deferral mechanism shall only be applicable to contributions in cash and (ii) any amount exceeding the statutory minimum capital must still be paid at the moment of incorporation. It remains to be seen how the latter will be interpreted by the Lux authorities, considering e.g., a lot of US fund managers generally use a USD equivalent for the purposes of the 12k minimum share capital.

What banks typically ask after incorporation

Once the entity has been incorporated, banks will generally request a final round of documentation to complete their onboarding process and fully activate the account. In practice, this involves a combination of incorporation documents, evidence of registration with the Luxembourg authorities, identification information for the company and its representatives, and confirmations relating to the ownership. 

The exact scope and sequencing of these requests can vary from one bank to another and will depend on the nature of the structure, the jurisdictions involved and the bank’s internal policies. 

Timing

In practice, the onboarding process typically takes a minimum of 4 weeks for new sponsors, depending on the bank’s internal approval procedures, risk assessment and (crucially) the quality, consistency and completeness of the information provided upfront.

Understanding the bank’s expectations early, aligning corporate structuring decisions with AML/KYC requirements, and anticipating follow-up questions can significantly reduce friction and avoid costly delays. Beyond initial onboarding, ongoing compliance with reporting and monitoring obligations remains essential to ensuring smooth day-to-day banking operations.

3) Conclusion

While Luxembourg is a highly sponsor-friendly jurisdiction in Europe, making it an attractive choice for fund sponsors establishing their fund and GP, it is important for new sponsors to be well prepared in the context of banking onboarding and AML requirements.

For U.S. sponsors, navigating European incorporation formalities, aligning U.S. ownership and governance structures with local expectations, and responding to detailed bank and AML information requests may require a shift in approach. 

Successful and timely execution ultimately comes down to strong alignment between legal, tax, banking advisors, and the sponsor team. This is where having the right local partners makes a tangible difference. With deep experience supporting U.S. sponsors, our firm guides clients through each stage of this process. By anticipating issues before they arise, organizing communication with Luxembourg notaries and managing the process end-to-end, we help sponsors focus on launching their fund, rather than navigating administrative complexity.
