Clients Sueing Coaches

I am currently enrolled in the coaching certification program, and I am concerned about being a solopreneur because I am worried about being sued by a client.

What can coaches do to prevent themselves from being sued?

I understand that coaches are not responsible for their client’s success or lack of success; if we put that in writing in the contract, will that provide enough protection for us?

However, we live in a litigious world.

Thank you!
