A mortgage on property owned by husband and wife as tenants by entireties was valid, even though signed by only one spouse, when the signing spouse normally handled the finances for the family and the non-signing spouse benefitted from the mortgage because the proceeds were used to repay an existing mortgage, and so the “entireties presumption” applied and the signing spouse had the authority to act for both spouses with respect to entireties property without the specific authority the other spouse.
