Is the action/process of sharing something out among a number of recipients (beneficiaries). The distribution of the trust assets had been previously determined/planned by the Trustor (creator of the trust) and is stated within the trust.
The trust may have provisions that a child cannot receive their portion until a certain age, and this would mean the Successor Trustee may have to supervise that child’s portion until they reach the age that was required within the trusts provisions.
