Most guides to forming a Lithuanian UAB walk through the same sequence: reserve a name, draft the founding agreement, deposit share capital, register with the Centre of Registers. What almost none of them mention is that the founding agreement itself has an expiry date. Under Lithuanian law, founding documents that are approved but not submitted to the Register of Legal Entities within six months simply stop being valid. Not delayed. Not flagged for review. Invalid, as if they had never been signed. For founders who pause mid-process, whether due to a financing delay, a banking hold-up, or simply deciding to take more time, this is the deadline that quietly turns weeks of preparation into a redo.
Founding documents are not permanent until they are registered
Lithuanian company law treats the period between signing your founding documents and registering the company as a window, not an open-ended state. The founding agreement (steigimo sutartis, for multiple founders) or founding act (steigimo aktas, for a sole founder), along with the articles of association approved alongside it, must be submitted to the Register of Legal Entities within six months of the date the decision to approve them was made. If that window closes without submission, the documents lose legal validity. There is no grace period and no automatic extension built into the default rule.
This sits alongside, and is easy to confuse with, a second and separate deadline: the period for paying initial share capital contributions into the company's accumulation account, which is set out in the founding agreement itself but cannot exceed twelve months from the date the agreement was signed. The two deadlines run on different clocks and protect against different problems. The six-month rule protects the integrity of the registration process itself. The twelve-month rule protects against share capital commitments being left open indefinitely.
What the six-month window actually covers
"Founders treat the founding agreement as a fixed starting point. Legally, it is closer to a ticket with an expiry date. If you do not use it within six months, it stops being valid, and the preparation work has to be done again from the approval stage."
The situations where six months disappears faster than expected
Six months sounds like a generous window for what is, on paper, a process that the Lithuanian Centre of Registers can complete within one to three business days once documents are submitted. The gap between "registration is fast" and "founders sometimes run out of time anyway" comes from what happens between signing the founding documents and actually filing them.
For a foreign founder, signing the founding documents is often not the last step before registration; it is the start of a sequence that includes opening a Lithuanian bank account or e-money account for the share capital deposit, obtaining notarised or apostilled documents from abroad, coordinating signatures across time zones, and sometimes resolving a registered office address before the application can be finalised. Each of these steps can independently take weeks, and they often run in sequence rather than in parallel when founders are managing the process without local support.
A six-month window that looks comfortable on day one can be substantially eroded by the time banking and documentation logistics for a non-resident founder are actually completed. The risk is highest for founders who pause the process partway through, intending to pick it back up later, without realising the clock did not pause with them.
Founding documents are sometimes signed before every commercial detail is finalised, for example while a co-founder negotiation, an investor commitment, or a supplier agreement is still being worked out. If that external dependency takes longer than expected, which is common, the founding documents sit unregistered while the underlying business question gets resolved. Six months can pass during what felt, at the time, like a short pause.
If your founding documents have been signed but registration is being deliberately delayed for a business reason, it is worth tracking the six-month date explicitly, rather than assuming the documents will simply wait.
Set under Lithuanian civil law for legal entity founding documents generally, applying to the steigimo sutartis or steigimo aktas and the articles of association approved with them. If registration is not submitted within this period, the documents must be re-approved before the process can continue.
Missing the deadline means redoing the approval, not just resubmitting
If the six-month window closes, the practical consequence is not a late fee or a warning notice from the Register of Legal Entities, because the documents are never submitted in the first place. The consequence is that the documents you already signed cannot be used. The founders need to approve new founding documents: in practice, this usually means redrafting and re-signing the founding agreement or act, reconfirming or updating the articles of association, and in many cases re-approving the founders' decision or minutes that originally authorised the founding terms.
For a single founder using standard template documents, this is an inconvenience rather than a crisis: redoing a founding act is comparatively quick. For a multi-founder company, particularly one with international founders who needed time to coordinate notarisation, translation, or signatures across countries the first time, redoing the founding agreement means repeating that same coordination effort a second time, often under more time pressure than the first attempt.
| Situation | What needs to happen |
|---|---|
| Sole founder, documents expired | Re-approve the founding act (steigimo aktas) and articles of association, then submit promptly |
| Multiple founders, documents expired | Re-negotiate and re-sign the founding agreement (steigimo sutartis), reconfirm articles of association, often requiring fresh notarisation if any founder is a natural person |
| Foreign founder documents, expired | Repeat any apostille, notarisation, or certified translation steps that applied the first time, in addition to re-signing |
| Share capital already deposited before expiry | Confirm with your bank or e-money provider whether the deposit remains valid against new founding documents, or needs to be reconfirmed |
If you have signed founding documents for a Lithuanian UAB and registration has not yet been submitted, the relevant date to track is not when you plan to finish, it is six months from the date the documents were approved. Treat that date as a hard deadline regardless of where the rest of the process stands.
1Office Lithuania manages the founding document timeline as part of company formation, tracking the six-month registration window and the separate twelve-month share capital deadline so founders are never caught by either.
1Office Lithuania can review your founding documents and confirm exactly how much time remains before registration must be submitted.
Frequently asked questions
Do Lithuanian company founding documents expire?
Yes. Under Lithuanian law, a legal entity's founding documents (the steigimo sutartis or steigimo aktas, together with the articles of association) lose validity if they are not submitted to the Register of Legal Entities within six months from the date the decision to approve them was made, unless a different deadline is set by law for that specific legal form. If the six-month window passes without registration, the documents must be re-approved before the process can continue.
What happens if I miss the deadline to register my Lithuanian UAB after signing the founding agreement?
The founding documents become legally invalid once the six-month window closes. The founders need to approve new founding documents, which in practice means redrafting and re-signing the founding agreement or act and reconfirming the articles of association, before submission to the Register of Legal Entities can proceed.
Does the six-month rule apply to share capital deposits too?
No, that is a separate and longer deadline. Initial capital contributions for subscribed shares must be paid into the company's accumulation account within the period set out in the founding agreement or act, which cannot exceed twelve months from the date the agreement or act was signed. The six-month registration deadline and the twelve-month capital deposit deadline run independently and should both be tracked.
Why does this catch foreign founders more often than local ones?
International founders typically have more steps between signing founding documents and submitting registration: opening a Lithuanian bank or e-money account, obtaining notarised or apostilled documents from abroad, coordinating signatures across time zones, and securing a registered office address. Each step can take longer than expected, and a six-month window that looks comfortable at the outset can be substantially used up by logistics alone, particularly if the process pauses partway through for any reason.
