I no longer sell real estate so it could have changed ( I only do mortgages now days)
In California a buyer has 3 days to back out after getting any disclosure and get their full deposit back. So when I sold real estate I was a bit lax on it if I were the buyers agent. If anything went sideways and we needed out of the transaction not having the disclosures could turn into an asset. Many of the listing agents seemed to fall down on this point as well.
If I was a listing agent non the other hand, the buyers got their disclosures attached to the accepted purchase agreement.
I know it sounds a bit slimy, but as an agent I felt my job was to represent my customer and their interests. I never had a customer lose a deposit, though I did have to fight for one for about 7 months.
But yes the residential purchase agreement does call for the disclosures to be made within 7 days unless on line 14A, another time period is put in there.
