signed on the dotted line

Made it official

To sign on the dotted line is to commit formally to an agreement, contract, or obligation—from the literal line where signatures go on documents.

The phrase often emphasizes finality or reluctance: I had my doubts, but I signed on the dotted line.

It can mark the moment a deal becomes binding: Once you sign on the dotted line, there's no backing out.
