Sorry it took me longer than expected to find this. I think this answers your question. So long as your married whether you have a will or not your spouse is entitled to the spousal share. The only way you can avoid this is to divorce her.
Here is the relevant statute language:
§ 30-15. When spouse entitled to allowance.
Every surviving spouse of an intestate or of a testator, whether or not the surviving spouse has petitioned for an elective share, shall, unless the surviving spouse has forfeited the surviving spouse's right thereto, as provided by law, be entitled, out of the personal property of the deceased spouse, to an allowance of the value of thirty thousand dollars ($30,000) for the surviving spouse's support for one year after the death of the deceased spouse. Such allowance shall be exempt from any lien, by judgment or execution, acquired against the property of the deceased spouse, and shall, in cases of testacy, be charged against the share of the surviving spouse. (1868-9, c. 93, s. 81; 1871-2, c. 193, s. 44; 1880, c. 42; Code, s. 2116; 1889, c. 499, s. 2; Rev., s. 3091; C.S., s. 4108; 1953, c. 913, s. 1; 1961, c. 316, s. 1; c. 749, s. 1; 1969, c. 14; 1981, c. 413, s. 1; 1995, c. 262, s. 4; 2000-178, s. 4; 2009-183, s. 1; 2011-344, s. 7; 2013-81, s. 1.)
