Documents Required for SIA Registration: Complete List

The Register of Enterprises in Latvia returns roughly 20% of SIA applications due to incomplete or incorrectly prepared documents. Knowing exactly what to prepare before you start saves at least one round of corrections — and the 2–5 business days that each correction cycle adds.

Here's the complete document list for SIA registration in 2026, with notes on common errors for each.

Required Documents

1. Application for registration (Pieteikums ierakstīšanai komercreģistrā)

The standard form available on the Register of Enterprises website. Contains company name, legal address, information about founders and board members, share capital amount, and NACE activity codes. The most common error: incorrect or missing NACE codes. Select all relevant activity codes — not just your primary one.

2. Articles of association (Statūti)

The company's constitutional document. Specifies: company name, share capital amount, share structure, shareholder rights, board member appointment rules, and profit distribution procedures. For single-shareholder SIAs, the Register provides a standard template that most founders use as-is. Custom statutes require more careful drafting — inconsistencies between the statutes and other documents trigger rejections.

3. Founder's decision or meeting protocol

Single founder: a written decision establishing the company, approving the statutes, and appointing the board member. Multiple founders: a meeting protocol documenting the same decisions, signed by all founders.

4. Share capital deposit certificate

A bank certificate confirming that the share capital (EUR 2,800 standard or chosen micro-capital amount) has been deposited into a temporary accumulation account. The certificate must come from a Latvian bank and reference the company-in-formation. This is the document that causes the most delay — because it requires the bank account to be set up first.

5. Legal address confirmation

Proof that the company has a registered address in Latvia. This can be:

• A lease agreement with the property owner (with a clause permitting use as legal address)
• A virtual office service agreement
• Property ownership documents (if you own the premises)
• Written consent from the property owner (if not included in the lease)

6. Board member's consent (Valdes locekļa piekrišana)

A signed document confirming that the appointed board member accepts the position. Includes their personal details and signature.

7. Identification documents

Copies of founders' and board members' passports or ID cards. For non-residents: apostilled copies may be required depending on the country of origin.

For Electronic Submission

If filing through the Register's online portal, all documents must be signed with a qualified electronic signature (eParaksts or equivalent EU-recognized e-signature). Documents submitted electronically don't require notarization in most single-shareholder cases — a significant cost saver.
