First comment (please do not take it wrong), if you are accepting documents for a trust, and do not understand the wording, it should go through someone else in the department that can accept responsibility for accepting it. There may be too much liability for accepting a response from BOL, especially if there is a state law interpretation.
From internet.
The natural meaning of the word ‘issue’ is descendants of all degrees, meaning one’s children, grandchildren, great-grandchildren etc. Interpretation problems can arise when it appears in the will that this term was intended to mean only the first generation of descendants, or ‘children.’ The word ‘issue’ will only be given the secondary meaning of ‘children’ if that meaning was intended by the testator, based on clear and cogent evidence from the rest of the will.1 Therefore, my recommendation is to only use ‘issue’ in a will in the context of its primary natural meaning of descendants of all degrees.
