If a husband or wife makes a valid devise of real estate to his or her spouse, for life or otherwise, without expressing whether or not it is intended to be in lieu or bar of dower or curtesy, the surviving spouse shall not be entitled to dower or curtesy in any real estate devised by the will, unless, within 6 months after probate of the will, he or she files with the surrogate of the county wherein he or she resides or wherein the real estate so devised to him or her is situate, a written refusal to receive the same in satisfaction and bar of dower or curtesy in other real estate. By such refusal he or she shall be deemed to have renounced the said devise.
