Well, your attorney said 4-6 weeks from the mediation, and you sgned the settlement paperwork a week after mediation. My estimate of 30-45 days after signing is about what your atty. told you.
Checks typically take 3 days to clear if it's an instate check, 5 days if it's out of state.
You can pick up the check at your atty's office if you say you want to pick up the check.
Your atty should be able to tell you all of this....
