ulawk: ulak (Turkish for messenger) + law — the messenger of law: whatever changes in the official register, it brings you the news.

And if anyone asks how you knew: a little bird told you.

    Two ways to work

    Add a company fast, check every fact at its source.

    The same record serves both: a quick add for your watchlist or your own forms, and a sourced view for decisions that need evidence.

    Quick add

    Type the RCS number or the name. The company’s details are filled in from the official record, so your list starts clean.

    Why it matters

    Not knowing is no excuse.

    A change in the official register can affect your contract, your loan or your claim from the day it is published. Nobody can follow hundreds of companies by hand.

    Once a change is published, you are expected to know about it.

    A counterparty whose director changes, whose capital is reduced or who goes into insolvency: you are expected to know. Ulawk checks every day, catches the change, tells you and updates the company profile.

    1. Add your companies

      By RCS number or by name, or as an Excel list. Companies in other countries by their local company number or LEI.

    2. We read the history

      Everything the official record holds is read and turned into a sourced profile.

    3. We check every day

      A new entry reaches your inbox the day it appears: its type, a plain summary and a link to the official record. Or into your own systems by webhook.

    4. You decide

      See officers, ownership, risk and sanctions in the profile where the register publishes them, download a PDF report or pull everything by API.

    Türkiye in depth

    What you learn about your Turkish partners.

    For every company on your list Ulawk reads the Turkish Trade Registry Gazette and KAP from incorporation onwards, and turns each notice into a sourced profile.

    When this matters

    • You import from Türkiye or export there
    • Your supplier or customer is a Turkish company
    • Your business has partners, shareholders or family companies in Türkiye
    • You give Turkish companies payment terms or credit limits

    Concordat filings in Türkiye rose markedly in the first half of 2026. If you have open receivables, you need to see a respite notice the day it is published: a notice spotted late can mean a missed deadline for your claim.

    Company file

    Instead of scattered records, one up-to-date file.

    Everything the LEI record holds, in one profile: legal name, legal form, status, address and group links, with every change on a timeline. Pick an entry to see the record behind it.

    Coverage

    What we cover, country by country.

    We state plainly what a profile contains in each country. Where there is no direct connection to the official register, we follow the company through its LEI record and say so.

    Coverage: Registry record

    Luxembourg companies through the international company identifier record (LEI) and the official annual accounts register.

    An RCS number is matched to its entry in the international company identifier record (LEI): name, legal form, status, address and parent/subsidiary links; a company without an LEI is linked through the official annual accounts register (name, annual accounts and filings). Annual accounts figures (turnover, result, total assets, equity) and filing dates come from the official annual accounts register; statements a company marked confidential or did not have to publish are shown as not public. Officers and shareholders are not included; the register of beneficial owners is not public.

    Who it's for

    For every team that works with company data.

    The same register data, four different questions. Each team follows its own list and gets its own alerts.

    Banks and finance

    Can this person sign this loan for the company?

    • Current officers at onboarding (KYB), wherever the register publishes them
    • Ownership and control as filed, with the source
    • Officer changes, capital cuts and insolvency notices across the loan book; by webhook into your systems

    Law firms

    Who represents the other side today?

    • Before signing: who holds office at the counterparty
    • In disputes: current address, officers, insolvency and liquidation status
    • In M&A: the history of shareholders, mergers and name changes

    Investors and funds

    Has anything changed at our portfolio company?

    • Capital increases and new shareholders as they are filed
    • Officer changes, share transfers, group links
    • Before investing: the record history from incorporation and related companies

    Companies

    Did the supplier we prepaid just go insolvent?

    • Add your supplier and customer list once from Excel
    • Liquidation, insolvency, strike-off and frequent officer changes flagged
    • Check who signs a contract before you sign it

    Business parks and incubators follow the companies on their site from one panel, too.

    Trust

    Every fact linked to its source.

    You do not have to wonder whether an AI summary is right. Every line in the profile is linked to the record that says it.

    The official record, one click away

    The source button opens the official record behind each fact. Information we cannot source does not go into the profile.

    No guessing

    If the register does not say it, we write “not in the record”. Calculated conclusions are marked as such. Report anything wrong from any line with one click.

    Full-name sanctions screening

    The company, its officers and shareholders are screened by full name against eight official lists, including the UN, OFAC, EU and UK lists. You confirm a possible hit with date of birth and nationality.

    GDPR

    Personal identifiers are masked. Your watchlist and notes stay in your account only; connections are encrypted and data is backed up regularly.

    Frequently asked

    Questions and answers

    If your question is not here, write to [email protected].

    Which official sources does Ulawk use for Luxembourg?

    Official annual accounts register of Luxembourg and international company identifier record (LEI). An RCS number is matched to its entry in the international company identifier record (LEI): name, legal form, status, address and parent/subsidiary links; a company without an LEI is linked through the official annual accounts register (name, annual accounts and filings). Annual accounts figures (turnover, result, total assets, equity) and filing dates come from the official annual accounts register; statements a company marked confidential or did not have to publish are shown as not public. Officers and shareholders are not included; the register of beneficial owners is not public.

    Which law and authorities govern Luxembourg companies?

    Civil law; commercial companies are governed by the law of 10 August 1915 and the register by the law of 19 December 2002. Authorities: Company registry: Official company register of Luxembourg; Official notices: Official gazette of Luxembourg; Public disclosure: Securities filings of Luxembourg; Financial supervision: Commission de Surveillance du Secteur Financier (CSSF); Central bank: Banque centrale du Luxembourg (BCL); Financial intelligence (AML): Cellule de renseignement financier (CRF); Beneficial ownership: Official beneficial ownership register of Luxembourg (not public). Ulawk shows official records; it is not legal advice.

    Can I follow Turkish companies together with Luxembourg companies?

    Yes. Turkish companies come from the Turkish Trade Registry Gazette, Luxembourg companies from their official source (official annual accounts register of Luxembourg and international company identifier record (LEI)); both are in the same panel, and a foreign company can be linked to a Turkish company as its shareholder or officer.

    Is the panel available in English?

    Yes. Choose Luxembourg from the flag menu and the panel switches to English, with dates and amounts in the local format.

    Is this legal advice or a credit rating?

    No. Ulawk shows official records with their source. Risk flags are explainable signals from public filings, not a credit score, and nothing here replaces legal advice.

    Never miss a change.

    Add your companies by RCS number or from Excel; new records reach you the day they appear, with their source.
