In Jain Dharma, a married couple are गृहस्थs (householders), and their vows are centered on dharma, mutual purity, restraint, and non-violence.

The main vows for a married Jain couple are:

1. Ahimsa — not to harm any living being, in body, speech, or mind.
2. Satya — to speak truthfully.
3. Asteya — not to take what is not given.
4. Brahmacharya / marital fidelity — to remain faithful to one’s spouse and keep purity in conduct.
5. Aparigraha — to keep limited possessions and avoid greed.

For married life, these are practiced as Anuvratas — the smaller vows for householders. A Jain couple also vows to:

• live with mutual respect,
• support each other in धर्म,
• avoid violence and harsh speech,
• observe restraint in desires,
• and practice compassion toward all beings.

In simple words, a Jain married couple’s vow is to live together in faithfulness, self-control, truth, non-violence, and spiritual support.
