Formal conditions (andernfalls, gegebenenfalls)

Consequences with "andernfalls"

In professional texts like software licenses, you often need to explain what happens if a requirement isn't met. To express "otherwise," use the formal adverb andernfalls.

Because andernfalls is an adverb, placing it at the start of a clause takes up the first position. The conjugated verb must immediately follow it.

You must buy the license, otherwise we will prohibit its use.
Sie müssen die Lizenz kaufen, andernfalls untersagen wir die Nutzung.
You must pay the fee, otherwise the developer will prohibit access.
Sie müssen die Gebühr bezahlen, andernfalls untersagt der Entwickler den Zugriff.

Conditional Actions with "gegebenenfalls"

To state that an action will be taken "if necessary" or "where applicable," use the adverb gegebenenfalls (often abbreviated as ggf.).

where applicable
gegebenenfalls

You can simply place gegebenenfalls in the middle field of a sentence—typically shortly after the conjugated verb—to add a formal condition.

If necessary, the developer will offer a paid license.
Der Entwickler bietet gegebenenfalls eine kostenpflichtige Lizenz an.
The developer will cancel paid subscriptions if necessary.
Der Entwickler kündigt gegebenenfalls kostenpflichtige Abos.

Because it functions as a regular adverb, it easily combines with causal clauses starting with da (since) or sentences connected by deshalb (therefore).

Da der Verstoß schwer ist, wird die Berechtigung gegebenenfalls ungültig.
The authorization is invalid; therefore, we will delete your account if necessary.
Die Berechtigung ist ungültig, deshalb löschen wir gegebenenfalls Ihr Konto.
