Answer

Yes — in Jain tradition, a Tirthankara is commonly described as having avadhi-jñāna in the final human birth. However, the exact way this is explained can vary slightly between the two sects.

• Digambara: generally accepts that a Tirthankara has avadhi-jñāna in the final life, often described as present from birth or very early life.
• Śvetāmbara: also accepts avadhi-jñāna for Tirthankaras, often explained as arising in the womb or very early, depending on the text and tradition.

Explanation

Avadhi-jñāna is a type of limited direct knowledge, not full omniscience. It lets one perceive things beyond ordinary sense perception, but it is still incomplete.

A Tirthankara does not attain kevala-jñāna at birth. Kevala-jñāna comes later, after the destruction of all knowledge-obscuring karmas.

So the usual Jain understanding is:

• Before kevala-jñāna: avadhi-jñāna may be present
• At kevala-jñāna: complete omniscience arises

Spiritual Understanding

This shows the extraordinary purity and merit of a Tirthankara’s soul even before complete enlightenment. Their life is unique, and their knowledge is not ordinary human knowledge.

Takeaway

So the short answer is: yes, broadly both sects accept avadhi-jñāna in a Tirthankara’s final birth, though the timing is described a little differently in different traditions.
