Another law school lesson courtesy of Wills, Trusts & Estates:
A court may find that a person does not have the mental capability to manage one's investments, to make a contract, or to make a gift.
A court may find that the same person does not have the mental capability to make a will.
But a court may find that same person does have the mental capability to get married.
Yes, a court upheld a marriage but invalidated a will made on the same day as the wedding. Funny that we have different levels of mental capacities for different types of contracts, and the lowest threshold is for marriage. It actually explains so much.
