Does severance delay my unemployment claim? - 12 weeks in

I was offered severance of 14 weeks after being let go as a web developer and I am unsure how it affects benefits. I have a mortgage and need to plan. Who should I ask before signing?

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

I filed on day one anyway and reported the severance honestly. The agency decided what to do about the timing.
