After notice to the qualified beneficiaries, a trustee may combine two (2) or more trusts into a single trust or divide a trust into two (2) or more separate trusts, if the result does not impair rights of any beneficiary or adversely affect the achievement of the purposes of the trust. If the trusts to be combined or divided have different trustees, the trustees may negotiate the terms of the combined or divided trusts, including which trust or trusts will be the surviving trust or trusts, who will be the trustee or trustees of the surviving trust or trusts and any other matter relating to the operation of the surviving trust or trusts.
