2020 Segunda División play-offs

The team that scored more goals on aggregate over the two legs advanced to the next round.

If the aggregate score was level, the away goals rule was applied (i.e., the team that scored more goals away from home over the two legs advanced).

If away goals were also equal, then thirty minutes of extra time would be played.

The away goals rule would again be applied after extra time (i.e., if there were goals scored during extra time and the aggregate score was still level, the visiting team advanced by virtue of more away goals scored).

If no goals were scored during extra time, the winner would be the best positioned team in the regular season.
