Legal Question in Investment Law in California

Your question is rather vague. Are you asking whether receipt of investment income may disqualify you from receiving your disability income? If so, I understand SSDI is not "means tested" and the fact that you have assets or income will not disqualify you. Your eligibility for SSDI benefits is based on prior employment and disability. For example, acting as a landlord and renting out investment property does not disqualify an SSDI recioient because doing the things landlords do (collecting rents, showing vacancies, etc.) is considered passive, as would be managing a stock portfolio.

Not sure what you mean by "asset protection." If you want asset protection, buy quality government bonds or put your money in an FDIC-insured bank account.

I suggest that you visit a local SSA office and discuss your concerns with an advisor.
