When people hire a lawyer, they are typically expecting this lawyer to be fully focused on their case and willing to put in hours of work researching and making plans to help their defense. In reality, lawyers are people too. They have lives outside of their work and they often have multiple cases at one time, which means that they can’t be fully focused on any given case.
It is actually better to spread the responsibility of research for the case and working on documents for it to a team of individuals. This is why many people seek lawyer assistance services where some of the research and document preparation is taken off of the lawyer’s hands. Having a team working on a case rather than one person can help make the case stronger.
