I hope you are having a wonderful holiday yourself. I am happy to hear that you are satisfied with my first response--please let me review the second question to see if I misunderstood it.
Currently we have on going case against a certain unit owner which owe us several month of common charge , The issue is when our attorney who is handle the said case send me a bill dated on Aug9 , and requested me to pay the bill right away , but in our agreement , we have 30 days to review and pay , the attorney get mad and inform the lawyer of the other party (unit owner ) that ‘there is a lien for my legal fees (to be calculated to the present date later today) and imply any settlement between the unit owner and me , the attorney of unit owner should pay his legal bill first because we owe him money
Legally he is within his rights to do so. He is owed money if you haven't paid the bill. I do agree that if you had 30 days to pay, you are not yet in breach of contract, but the debt is valid--as a consequence that obligation can be disclosed and used as a means to place a lien against the settlement amount. He does not have to wait 30 days to place this interest, he can do so the moment the debt is valid. While it is possibly shady, it is not illegal.
When I question him why he lien the settlement for his legal fee , he cited ABA Rules of Professional Conduct 1.8.i.1 (which is my first question ) do you think he is right or he violate any professional conduct
I do not see this violating the professional conduct in this instance based on my explanation above. I do apologize for the confusion, I thought you replaced the attorney with someone else, but in this case letting the other side know that he has an interest in the settlement is not a violation.
