What agent told you this? PM if you don't want to post here.
Basically under section 107(6) of the Belize International Companies Act.
107(6) A company that has been struck off the Register under this section remains liable for all claims, debts, liabilities and obligations of the company, and the striking off does not affect the liability of any of its members, directors, officers or agents.
109(3) The fact that the name of a company is struck off the Register
does not prevent,
(a) the company from incurring liabilities;
(b) any creditor from making a claim against the company and pursuing the claim through to judgment or execution; or
(c) the appointment by the court of an official liquidator for the company under section 110 of this Act.
111(1) If the name of a company has been struck off the Register under section 107 of this Act and remains struck off continuously for a period of three years, the company shall be deemed to have been dissolved.....
So basically you have a three year wait for company to be considered officially dissolved. Striking off and dissolution of a Belize company are two totally different things. Basically no one is gonna come after a Belize company and Belize will not come after you unless you did something really shady with the company in which case creditors can themselves actually pay to get the company put back on the register over the next three years and come after you in worst case.
