hinzuzuziehen

Hinzuziehen is a German verb that means to bring someone in or to involve someone in a process, in particular to consult or obtain the input of a person or expert. It is commonly used in professional, legal, medical, scientific, and administrative contexts when additional expertise or information is required to make a decision or assessment. A related expression is zu Rate ziehen, which means to consult someone for advice.

Grammatically, hinzuziehen is a separable verb. In present tense, the prefix hin- is separated from ziehen, so a sentence can say: Wir ziehen den Berater hinzu. In the past tense, the participle is hinzugezogen, as in: Bei der Untersuchung wurde ein Sachverständiger hinzugezogen. The infinitive with zu is often formed as hinzuzuziehen, for example: Wir planen, einen externen Experten hinzuzuziehen. The simple infinitive without zu can also be used in many contexts: Wir sollten einen Experten hinzuziehen.

Usage notes and synonyms: hinzuziehen emphasizes the active act of bringing in external input or expertise rather than simply including someone. It is closely related to einbeziehen (to include) and hinzugekommenes Fachwissen, but it carries a nuance of sourcing additional authority or guidance. In formal or administrative language, hinzuziehen is common when documenting who was consulted or when describing the steps taken to obtain information or advice.
