DUGGAN, J. The petitioner, Deborah Beck, appeals a decree of the Rockingham County Probate Court (O’Neill, J.), which found that she is not entitled to a spousal share of the estate of David J. Bourassa. Beck argues that the trial court erred in failing to find that she was Bourassa’s common law spouse pursuant to RSA 457:39 (2004). Because the probate court reasonably held that Beck and Bourassa failed to acknowledge one another as husband and wife, as is required by RSA 457:39, we affirm.
