Answer

Yes, a non-Jain can become Jain.

Jain Dharma is not limited by birth, caste, nationality, or background. A person becomes Jain by accepting and practicing the principles taught by the Tirthankars, especially:

• Ahimsa — non-violence
• Satya — truthfulness
• Achaurya — not stealing
• Brahmacharya — purity and self-control
• Aparigraha — non-attachment

Explanation

In Jain Dharma, the soul is most important. Every soul has the potential to become pure and attain liberation. Therefore, anyone who sincerely follows Jain teachings can live as a Jain.

For a layperson, becoming Jain usually means:

• Having faith in Jain Dharma
• Following Jain ethical principles
• Practicing vegetarianism and non-violence
• Learning about Tirthankars, karma, soul, and liberation
• Following vows appropriate for householders
• Respecting Jain monks, nuns, scriptures, and temples

There is no requirement that one must be born in a Jain family.

Spiritual Understanding

Jain Dharma teaches that liberation depends on right faith, right knowledge, and right conduct — not on birth. A sincere person from any background can progress spiritually by reducing violence, attachment, passions, and karmic bondage.

Takeaway

Yes, anyone can become Jain if they sincerely accept Jain principles and try to live according to the path shown by the Tirthankars.
