A: Im sure there are lawyers that are willing to help you but that depends on if you have a viable claim. And unfortunately you did not provide us with much information to go on. Please advise on what the underlying claim is regarding and why you believe the attorney committed malpractice.
A: I'm not sure what you mean when you say the reason is "lost lease." If she continued to have a lease when she died, and still had more time left on the lease, then her estate is still responsible for those months. That being said he would be allowed to retain the security deposit to compensate him for those lost months and could still bring an action against the estate for any lost rents until the lease is completed.
