Answer

If you mean the Jain Ramayana tradition, then no — Sita does not attain moksha in that life. In one Jain account, after renouncing the world, she is said to be reborn as the King of the 12th heaven. In Jainism, moksha means complete liberation from all karmas and the cycle of birth and death. ( jainqq.org)

Explanation

So, Sita’s soul is shown as highly virtuous and spiritually elevated, but not yet fully liberated in that story. Heaven is still part of the cycle of rebirth; moksha is beyond that. ( jainqq.org)

Spiritual Understanding

In Jain Dharma, every soul has the capacity for liberation, but moksha comes only when all karmic bondage is destroyed. Sita is honored as a very pure and noble soul in Jain literature, yet that particular narrative places her in a heavenly birth, not final liberation. ( jainworld.com)

Takeaway

Sita is revered in Jainism, but in this version she does not attain moksha immediately; she attains a heavenly birth instead. ( jainqq.org)
