How do I know if what my lawyer did was legal malpractice?

It’s actually impossible to know for sure that your lawyer committed malpractice unless you consult another attorney. Often you have a feeling or an indication that the lawyer did not represent you properly, and that’s what causes you to contact an attorney who handles legal malpractice cases.
