Gifting question

[ltlhuzz]

My mother is executor of her father's estate. We are equal shares of that estate and each year she has gifted myself and my husband and herself and her husband the sum allowed by law. This year she claimed that my grandfather (who has dementia) agreed to only 2 gifting checks. My mother gave the checks to her and her husband (who is not part of the trust) and my question is, shouldn't one of the checks have gone to myself rather than her husband?
