點check 間 Partnership 仲存唔存在?

As this is not a limited company, you cannot check it from the Companies Registry. It is workable you can make a Business Registration search in IRD to check whether this firm is still registered or not. However, as you are one of the partners of the partnership firm, you can check with Inland Revenue Department for any tax return or tax affairs of the firm. And, it is quite useful to check whether the firm address is still used. If so, go to the address for checking for the mailings or even affairs of the firm. For more details of further actions, professional assistance in this issue is better seeked.
