When to use it

Use ざるをえない when circumstances force you to do something you would rather not do. There is no other realistic option, so you accept it reluctantly. It is common when talking about canceling plans, admitting facts or accepting a decision, as in 大雪おおゆきのため、中止ちゅうしせざるをえない (because of the heavy snow, we have no choice but to cancel).

Nuance

Formal or written in feel, but also heard in serious speech. It carries reluctance: the speaker does not want to do it. It describes a forced action, so it is not used for something the speaker happily chooses.

Compare

ほかない / しかない also mean "no choice but", but focus on there being no other method (待まつしかない). ざるをえない stresses outside pressure and reluctance: 事実じじつを認みとめざるをえない. なければならない is a plain obligation with no special feeling of being forced.

Tip: Remember the irregular form: する becomes せざるをえない, not しざるをえない. This is a classic test trap.
