Thank you for your questions. Please permit me to assist you with your concerns. As you have fairly complex multiple concerns, I will go line by line with my responses.
If a business was started while married and this was originally my career and job but It was taken over by my husband and he blocked me from having access to it. This business was based on the internet and international, It originally started with Apple 10 years ago, if in the case of a divorce how do I figure out what it is & income generated by this if I dont know what the name of it is.
That is a fairly tough situation--you have to know the name or at least if the entity even exists. Typically that could be found based on his tax returns or by doing searches via state entities to see if he was listed anywhere as a principal of this business. That may be found with a private investigator as that tends to be cheaper than an attorney.
Secondly can a lawyer find this by looking thru his banking accounts?
Bank accounts, likely not. It is possible if funds were directly wired from specific accounts, but if there are no deposits, a bank account is to be of limited used.
can it be discovered by his SSN?
Typically you would need an EIN (Employer Identification Number) of the company to track the entity directly.
what if he is hiding this in countries?
That makes it even harder to find, it is still possible far less likely.
or has transfered ownership to his mother or an illegal alien who is in the process of getting citizenship.
If such a transfer can be traced, perhaps seeing if it was for value or not would be useful, but such a transfer is not necessarily illegal or fraudulent.
Is this considered fraud?
Not necessarily--not enough information to answer that in one way or another.
Can a business be hidden by not using a SSN?
Yes, there is no obligation to start a business under an SSN, a registered agent can be used and some stated do not require the identities of principals so long as a third party is used as a formal agent.
If you apply for a taxpayed ID # XXXXX you need to put a SSN?
No, you do not.
What are my rights to this in a divorce and how do I find out what it is & how much income it brings in?
You can subpoena
the records if you claim those earnings were obtained while married
He has also used my email addresses then he has put a hack in this to say Im a hacker or redirected information back to himself. If we get a divorce, will he be required to pay me my share because he has kept this money all to himself and cut me out. is this also fraud?
That is not fraud since there is no inherent entitlement to you if you are not listed as part owner of the business, but if it was earned while married, it is a potential marital asset that would need to be disclosed and potentially split between the parties.
Hope that helps.
