Die Prozesskosten stehen in der Akte.

Here, die is plural.

In German, die can be:

• the article for a feminine singular noun
• the article for plural nouns

In this sentence, it is plural because Prozesskosten is plural, and the verb stehen is also in the plural form.

Because the second part, Kosten, means costs/expenses, and it is normally used as a plural noun in this kind of context.

A very useful rule for German compounds is:

• the last part decides the grammatical gender and number

So in Prozesskosten:

• Prozess = legal process / lawsuit
• Kosten = costs

That makes the whole word a plural noun: the legal costs / litigation costs.

Because the subject is plural: die Prozesskosten.

German verbs change depending on the subject:

• es steht = it stands / it says / it is written
• sie stehen = they stand / they are written / they are listed

Since Prozesskosten is plural, the verb must also be plural: stehen.

That is a very common question. Stehen does literally mean to stand, but German also uses it for information that appears somewhere in writing.

So etwas steht in der Akte can mean:

• something is written in the file
• something is listed in the file
• something appears in the file

This is a normal German way to talk about written information.

Because in is a two-way preposition in German.

With in:

• accusative is used for movement toward something
• dative is used for location in something

Here the sentence describes a location, not movement. The costs are in the file, not being put into it. So German uses the dative:

• nominative: die Akte
• dative: der Akte

So: in der Akte.

Akte usually means a file, case file, record, or dossier, especially in legal, bureaucratic, or administrative contexts.

So in a legal sentence like this, die Akte is usually the official file containing the documents for a case.

Not necessarily. In legal German, Prozess often means a lawsuit, court case, or trial.

So Prozesskosten usually means:

• legal costs
• court costs
• litigation costs

A learner might recognize Prozess from English process, but in this context the legal meaning is the important one.

It is a typical German compound noun:

• Prozess
  • Kosten = Prozesskosten

German often combines nouns into one longer word. The basic idea is:

• the last noun gives the main category
• the earlier noun describes it more precisely

So Kosten is the main idea, and Prozess- tells you what kind of costs they are.

Yes. German word order is more flexible than English word order.

You could also say:

In der Akte stehen die Prozesskosten.

That version emphasizes where they are. The meaning is very similar.

The important rule is that in a normal main clause, the finite verb stays in second position.

Because they are nouns, and all nouns are capitalized in German.

So:

• Prozesskosten = noun
• Akte = noun

This is one of the most noticeable spelling differences between German and English.
