Okla. Stat. tit. 60, § 1609.1

Damages for breach of trust - Contribution. Except as otherwise provided in subsections A and B of Section 175.57 of Title 60 of the Oklahoma Statutes, if more than one trustee is liable to the beneficiaries for a breach of trust, a trustee is entitled to contribution from the other trustee or trustees. A trustee is not entitled to contribution if the trustee was substantially more at fault than another trustee or if the trustee committed the breach of trust in bad faith or with reckless indifference to the purposes of the trust or the interests of the beneficiaries. A trustee who received a benefit from the breach of trust is not entitled to contribution from another trustee to the extent of the benefit received.
