“What is the law concerning the distribution of assets like a diamond ring to a minor child. Can the executor decide to hold it in a trust for the child on his own, even though the will doesn’t mention a trust? Or do the child’s parents or guardians have the say about when and how the child receives the ring?”
This depends on the language in the will. If the will is silent on the manner in which the assets are to be distributed OR leaves those decisions to the executor, then it is possible to set up some formal arrangement like a trust to distribute the ring. However, if there is language in the will controlling the distribution, then the executor must abide by the wishes of the deceased.
