Unlimited company (or Welsh (cwmni) anghyfyngedig). There is no limit on the liability of its members. It is not a requirement under company law to add or state the word or designation Unlimited or its abbreviations (Unltd., or Ultd.) at the ending of its legal company name, and most such companies do not do so. Unlimited companies are exempted from filing accounts with the Registrar of Companies for public disclosure, subject to a few exceptions (unless the company was a qualified subsidiary or a parent of a limited company during the accounting period).
For businesses in industries like construction or real estate, where unforeseen circumstances and hazardous conditions may hold the owner responsible, consider starting an LLC. The protection gained means you will not be held personally liable, protecting you and your family from litigation or the debts of the business. An LLC may not be the best choice for business owners who plan on raising capital through outside investment. LLCs are not public structures and do not have shareholders, so taking a company public is not an option either. However, in the event that you'd like to take your business public you may switch to a public legal structure, like a C corporation, later on.
