Are we owners?

Thus question is probably beyond the scope of , but I will change the category. BTW, It would be wise to avoid the passive voice in such inquiries.

Your question is unclear. I don't understand how you have the stock certificate if the seller never surrendered it. The stock certificate is evidence of ownership. Check with the corporation and see if they list you as a shareholder of record. If not, you probably have a claim against whoever sold you the shares, except there could be a statute of limitations problem. Talk to a lawyer ASAP as there are deadlines for making legal claims.

Your question is a little confusing please clarify

You don't say the most important fact: did the seller sell the stock to someone else? Because, if so, your only claim is an action against the sell for money. However, if the seller still owns the stock, he could (depends on other facts) be forced to give them to you since you paid for them. You need a lawyer to review any documentation, talk to the corporation and look up any relevant state corporate and contract law.
