I recently sold a company to an individual in NY. Now this individual is complaining left and right, and I can't deal with it anymore. There is one issue that is legitimate on his end, but the others are absurd. So I am willing to negotiate on the one issue, and to come down in a settlement negotiation. Now the individual is threatening suit and saying there are other issues. He is saying that there are compliance issues. I never had compliance issues before I sold the company to him, and he did his due diligence and I provided him with everything he needed. He did not retain counsel for due diligence and to review the PSA, he signed the PSA which is very beneficial to me. Now he is bringing up issues outside of the PSA, saying that the PSA doesnt contain what we negotiated.Is it my fault that the PSA doesnt contain his arguments? He should have retained counsel for this, correct? He did his due diligence and nothing came up under compliance issues before. I used an attorney for the PSA, but now I don't want to spend so many financial resources for that. What do you recommend? Thank you for your help. If he sues, then I will retain a good attorney.
