無限公司唔係法人,法律上同東主個人係冇分別!
For example, 你間無限公司叫 ABC Company,
你想轉做ABC Company Ltd. 首先要check吓 ABC Company Ltd.呢個公司名係咪已經有人用緊, 如果冇...當然可以成立ABC Company Ltd.
但係你所講嘅"經營歷史和商譽"就只有你講!因為ABC Company Ltd.嘅歷史就只有由成立嗰日開始!
至於你提及嘅"XXX Company O/B XXX Company Limited"
喺呢個example就即係 ABC Company O/B ABC Company Limited
ABC Company <--只不過係Trade name, ABC Company 只係under ABC Company Limited 嘅一個Branch.
伸延開去, 你可以有
ABC Company O/B ABC Company Limited
DEF Company O/B ABC Company Limited
GHI Company O/B ABC Company Limited
只要每一個Company攞一個BR
