Delaware: Delaware law presumes that real estate conveyed or deeded to a husband or wife during their marriage is a joint tenancy in common unless a joint tenancy is specifically created. During a marriage, a husband and wife may separately sell or mortgage real estate without their spouse signing onto it. The spouse may have an inheritance right, sometimes referred to as a dower, courtesy, or statutory share, in the real estate and usually the spouse joins in signing a contract, deed or mortgage. Delaware law requires that in the case of sale or mortgage both spouses sign the contract, deed or mortgage. Delaware Code §25-102 through 124; 25-311, 701.
