Severance and unemployment, do they overlap? - 14 weeks in

My employer is paying severance in instalments and I am not sure whether to file now. I have read a lot of threads here and could not find my exact situation. The agreement mentions a release and a payment schedule. Who should I ask before signing?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

Rules differ by state. I called the claims line and asked directly, then wrote down the answer and the date.
