A New Jersey executor may block a surviving spouse's attempts to withdraw assets from a decedent's estate where the couple was in the midst of a New Jersey divorce at the time of his death and where the transfers would result in unjust enrichment. Possible remedies include constructive trust, resulting trust, quasi-contract and implied contract. Kay v. Estate of Kay, New Jersey App. Div., February 2, 2009; N.J. Super. (App. Div. 2009)
