My spouse died 4 years ago. No will was filed. I just found $1000 worth of stock she owned. Is this likely?

Haha...she was saving for her and your future maybe? It might cost you more than the stocks are worth...but you can save a lot by doing the paperwork yourself. I believe that all states now have self service law available in civil cases. Call your courthouse. They will explain the process and the fees involved.
