seal someone's fate

Guarantee inevitable outcome

To seal someone's fate is to make an outcome inevitable, usually a negative one.

The expression suggests that once fate is sealed, like a letter or document, it cannot be changed or reopened.

His refusal to cooperate sealed his fate with the committee.

The phrase often appears in contexts involving doom, failure, or punishment, though it can occasionally refer to positive outcomes that become certain.
